UPDATE and MORE PROBLEMS with my KA-T=(

[doriftomunkee]

alright to whom that has been following my story here's the update on it. If you want to view the history here you go:

http://www.nicoclub.com/zerothread?id=98332

but newayz.

heres the update:

-car was running pretty good and i had some taste of quick boosting (playing it safe coz dont wanna blow anything up)

**I had 2.5 qt of oil at the time since i didnt wanna have the drain line backed up. new plugs...intalled ngk plug wires and timed it to 16. Car run nicely and sounded sweet.**

-I noticed a slight ticking on the lifters so i figured i need more oil..added atleast a qt.

-washed my car to take pics for you guys when car started to act up again.

It started to misfire again like a mofo and had alot of white smokes out of the exhaust smelling like fuel. I did check my coolant but it was clean. BUT my oil seemed watery and smelled like crazee fuel.

WHAT IS CAUSING MY OIL TO MIX WITH GAS!!????!!!

TIMING GOT JACKED UP AGAIN EVEN THO I HAD IT SET!

I STARTED SEEING OIL COMING OUT OF THE TURBO=x

so heres what i did:

-drained oil and put new one in there ..only 2.5qt again to play it safe

-installed new NISSAN orings to fix maybe oring injector leakages

-cleaned plugs

NOW HERE'S WHATS HAPPENING AS I LEFT IT FOR THE NIGHT:

-car still idles roughly and SMELLS LIKE FUEL! The car would turn on with no problem when i have the fuel pump relay out and the car would idle for about 5min or so before it stalls...but it starts right up...I EVEN TRIED IT WITH THE INJECTOR HARNESS UNPLUG AND IT STILL WAS ON FOR A BIT OF TIME!

So when i finally have it release all pressure ( car wont start anymore), I plug the injectors harness back and plug the fuel pump fuse. IT would turn on but same junk...it has crazee white smokes and its smells so strong! So i turn it off and try to crank again...JUNK WONT TURN ON...IT CRANKS AND CRANKS AND SOMETIMES IT WONT EVEN CRANK..LIKE IT WAS LOCKED UP OR THE STARTER IS NOT STRONG ENOUGH TO TURN. I did check my battery and its still 12.54 so its still good.

ANOTHER THING...I SEE FUEL DRIPPING DOWN THE EXHAUST PIPING FLANGES AND ALL THE WAY DOWN THE MUFFLER!!...MY FLOOR IS WET WITH FUEL NOW FROM THE DRIPS...

AT THIS TIME IM SOO FRUSTRATED AND PISSED WITH THIS CAR B/C EVERYDAY I HAVE TO BUY NEW PARTS AND WORK ON IT BUT TO ONLY FIND MORE PROBLEMS..IT SEEMS TO GET WORST AND WORST.

I was talkin to my bro since he just got home and i showed/explained to him the situation. He said he hears the injectors spraying fully and loudly from the moment i put the key on ACC. We talked and thought about it. That could be the reason why my car is soo flooded with fuel. But i cant think of anyway what is causing the injectors to do that other than the ECU sending signals for it. I do have still a AUTO ecu after my 5spd swap. But I heard that auto ecu will work just fine but have rough idle till it warms up. So i dunno. I AM STUCK HERE. ANY HELP/SUGGESTIONS WOULD BE GREAT GUYS.

I DIDNDT EVEN GET ANY PICS FOR IT SINCE THIS CRAP CAME UP. BUT I DO HAVE A SNEAK PEAK..PLEASE DO HELP ME AND THANKS IN ADVANCE

heres the walkthrough:



AND FINALLY.....(drum roll)



but newayz...HELP ME OUT AND POST YOUR COMMENTS/SUGGESTIONS/IDEAS ...THANKS DUDE..I LOVE YOU GUYS FOR ALL YOUR HELP

anyone?

[fiznat]

okay I told you over AIM but just to keep it on board in case people wanna add to it or whatever...

-check your fuel pressure-check your s-afc. I would actually just disconnect it and see what happens-check your MAF sensor-check your injectors (resistance test/noid light/and bench test the flow if youre ambitious enough)

The fuel in the oil is most likely from you running incredibly rich and the fuel just washing down the cyls... Even though fuel in the oil is usually a sign of worn rings, I really dont think this is the case in your car.

If you cant find anything wrong with your fueling (even though I REALLY think thats where your problem is), start checking for ignition failures...

[turtl631]

Um, only using 2.5 quarts seems like a bad idea to me...is that somehting you do when you're just breaking in a setup? KA holds 4 quarts and having the lines to/from the turbo would use up even a tiny bit more. I'd imagine you should fill it with the normal amount of oil.

[doriftomunkee]

I have a problem of the oil backing up the oil return line b/c i start to see oil drippingfrom the turbo area if i add close to full capacity of oil...i only put 2.5 qt b/c thats the amount im sure that the line wont get backed up with oil to the turbo..i am aware that factory spec is 3.74qt...but yea...anyone else? ideas and such?

[Structure240sx]

i also have to keep about 2.5q of oil in my pan for the same reason.

to get the oil level just right do this:jack up the car all around as level as possibleremove return line from panfill with oil until it drips out of the return bungremove dipstick and mark off new oil levelput return line back on

i just dont understand how it can run for that long. as fo having tons of fuel spray in the maf is a defintily possibility

[hannibal]

I'm curioous about this 2.5qt thing. Where do you have the return bung installed? Maybe its not close enough to the top of the pan...

[Structure240sx]

mine is about 1 inch from the top of the pan i believe. the bottom of the bung is maybe 1.5" down. the directions in my nsport kit i believe said 3inches from the front of the pan and one inch down. there may have been a spot weld around there my grandfather said would crack if he welded there. so we had to move it slightly

[NateDogg]

Did you lube the o-rings when you installed them??

Really sounds like an injector problem. They shouldn't be spraying when you have the key 'ON'. Maybe turn the key to "ON' and then pull the plugs to see which are soaked. That will tell you which injectors are leaing.

[WDRacing]

This low oil thing is a new one on me...lol. ARe you guys sharing the same crack pipe Tony?

White smoke billowing out the exhaust means your eating water. Could be an intake gasket or head.

Another thing, I've never seen fuel leak all the way into the exhaust piping!!! WTF are you doing over there? That means it would have to pool up in the block, perhaps leaking past the rings and mixing in the oil, exit the exhaust ports when turned over and run out through the turbo into the downpipe.

You have serious issues my friend.

[doriftomunkee]

well ya thanks for the encouragin words wdracing...i need some advice not words to bring me down...heres what happend today...i found from the plugs that #2 injector is leaking..well right about where im about to compression test my car and such...starter gave out on me=(...now im really discouraged about this car...as for the orings..i did lube them with petroleum based grease and tighten the bolts just enough for me to handtight and torque them. any other ideas?

[DammitBobby]

I am by no means an expert and my KAT project is not finished. Do I feel your pain YES! Anyway from my experience I have found a few things are important. Fuel gauge that is connected on the pressure side and not the return side(Oh yea I did that one my friend let me know how smart that one was!) It is important to know your pressure because the computer does not compensate for pressure changes. So a stock 240sx should be around 35psi at idle. So if you hook up a fuel gauge and it is reading a lot higher then you will know you have fuel pressure problems. If your pressure is correct then you need to look elsewhere.

[skatanic28]

another vote for leaking injectors/o-rings here.

will an impedence test ensure a non-leaking injector?or do you have to pull the rail / flow test them?

[doriftomunkee]

man ...my starter gave out on me since i been cranking and cranking the car to trouble shoot..well after so much scratches on my arms..i got it ..now the car cranks but wont start...man the fuel flooding is soo bad that after i turn off ignition i could here inside the motor like a sink draining water..and i see soo much fuel just dripping out of my exhaust pipings...its like a faucet man...i wasted a line i think since i parked the car in the garage with this problem...what can i do now? is there anything else to do here? how can i move forward and fix this...comon guys i know u prolly annoyed at me by now but please...pretty please heh

[DammitBobby]

I am bored tonight and read your post a few times. I am going to take a guess you have multiple problems. My guess you have a blown head gasket. That fuel you have flowing out of the exhaust pipe is water mixed with fuel. 2nd guess is you have either to much fuel pressure or you might have a intake valve sticking open. I would stop what you are doing now since nothing is working. Try doing a compression test. This will tell you wether or not you have a blown head gasket or valve stuck open. Did you replace your timing chain?? Maybe the cams are not lined up correctly. You can get a compression gauge for around 40bucks. A fuel pressure gauge for under 20. Both would be good investments and would you give you a lot more info about what is going on with your car.

[Projex240]

If the o-ring is leacking that is definately the problem, its like having the pump pour fuel stright into the cylinder. It can be fixed, but you need to have the oil drained before cranking it again.Do a comp tes after the starter gets replaced. Oh and from cranking over and over, are you sure its the starter and not just the battery being dead from cranking it so many times?Good luck.

[bruinbear714]

If you have a multimeter, you can check the voltage on the injector plugs to see if they are kept open with key in ACC position.

Or, see if you can hear the injectors click when the engine is started.

Fuel dripping out of exhaust = bad injectors, leaky o-rings, or like the dude above said, blown head gasket mixing with fuel and forced out through the exhaust.

[WDRacing]

Any 12VDC test light will show power at the injectors.

[DammitBobby]

Haven`t I seen that pic on some truckers mud flaps? LOL and what are you doing up at 1:30am?

[eddiec]

i once had leaky injector o-rings. it took several tries to get it right, but here is the skinny. at first i replaced the rings and hooked everything up only to find out they still leaked. in the end i installed the injectors and hooked up all the plumbing, but left the fuel rail hanging loose. then turn on the key, which turns on the fuel pump and pressurizes the system. if you still have a leaker you'll know. the injector itself should not leak out the tip, but fuel will come out around it where the o-ring is supposed to do its job. also having one leak will allow that pressurzed fuel to leak put into the cylinder. i also had fuel run into the exhaust.

like someone said above do a cylinder pressure test. that will tell if you have a bad head gasket.

also if your starter dies try whacking it with a hammer. sometimes after continuous crankning they heat up and seize. dont beat it to death. just a few persuasive blows should do the trick.

hope some of that helps.

[doriftomunkee]

i will be working on it today..ill keep u guys posted and see wat happens

[Projex240]

I didnt know they did that. Sweet--learned something new today. Last time my starter quit, i reaplaced it. I still have it..i wonder if its still good.

-Josh

[klattr1]

if you think its a headgasket problem, try a leak down test.sometimes compression tests wont show a leaking headgasket at all.

[doriftomunkee]

update after working on it today.

-drained the oil and man! its like draining a gas tank...so there goes all my gas =P IM ON "E" now hehe..

-cleaned plugs

-took out 370cc and put stock ones back in..JUST AS I SUSPECTED..it was injecto #2 leaking b/c when i pulled it...the bottom oring was ripped.=(.

GOODNEWS!

-car now starts and idles perfectly...no more white scary smoke in the exhaust and no more leak as it seems.

-i finished cleaning up my interior and put it back together.. its coming along pretty nicely

NEW ISSUES:

-took out safc and 370cc and will NEED to sell them to afford and get a fmu. you guys think 12:1 too rich for my set up.??

-i hear a hissing sound around the turbo area and i cant seem to locate it. i was using my stethoscope and still cant find it..

-i test drove it and now i have a hesitation problem during boost rpms around 2k-3k

-after i drove it i pulled over to my garage and i see smokes coming out the turbo from the exhaust turbine compressor housing..not sure if its just something evaporating or if my turbo is blown.

WHAT I DID:

-checked the maf and it was good before and now this new problem

-double check and made sure all the ecu harness wiring were good since safc removal

so now i have to figure this out.

CAR IS NOW BACK TO 20 degrees TIMING (my timing light is acting up=X

DID COMPRESSION TEST ON ALL CYLINDERS..CAME AROUND 145-150 ALL ACROSS...seems low since fsm is 151 min....so i did the wet test and they all bump to 155..so i guess my piston rings are worn out either way..but now i have no fuel flooding problems...so thats okay with me.

any suggestions wit this hesitation? could it be that vacuum leak i think i hear and cant locate...or its prolly turbo blown coz of the smoke..both would make sense to me b/c they have the same symptoms...i just hope its a vacuum leak...thats it for today..i might work on it some more tomorrow...

ANYONE WANNA BUY 370CC INJECTORS AND SAFC? 300 SHIPPED FOR BOTH...i realized my set up is not needing this fuel management and is more of a headache for me to tune..just wanna go ahead and get a fmu and boost away=)

ANYONE GOT A FMU FOR SALE...I CAN DO A TRADE PLUS CASH...help each other out

thanks for any help guys...

[fiznat]

Nice, I'm glad it was something as small as an injector leak.

The smoke coming from your turbo is most likely burning oil. It is possible that either the seals are worn OR you are feeding it too much oil. Did you put a restrictor inline on your turbo oil feed? It should be about -1AN or 1/16". The restrictor size is different for BB turbos but I dont think you have one if I remember right...

...Or it could just be oil that you dropped on the exhaust mani or in that area at some point... See if it keeps happening but install that restrictor if you dont already have one.

[nissanfanatic]

I am very tempted to do the trade, but I need to replace engine mounts and I need a wideband before I go near that stuff. If I have 300 before you find another buyer, consider it yours.

Did you forget to open the throttle on the compression test?

About the hesitation, did you set timing correctly? Check the tech section at http://www.ka-t.org I had really annoying hesitation issues because of improper timing setting.

[doriftomunkee]

oh ya stupid me..i was so concerned with the compression test i forgot to do it right...i didnt step on the gas on the floor hehe...well i guess ill try again tomorrow...but yea i need a fmu badly...i just want to start driving it..as far as the turbo goes..im not sure wat it is...ill check it tomorrow...and ill set timing as well..maybe ill HOPEFULLY get rid of the hesitation issues...MAN I NEED TO GET GAS AGAIN..HEHE..well thanks guys...let me know if anyone got a fmu for me..heh

[nissanfanatic]

How much would you want with a 8:1 Vortech FMU with 1600 miles on it?

[00_Altima MD]

ok a few things that you can check first. have you checked the ECT or IAT and also another thing you should check is the O2 sensor. you also might want to check the secondary wiring in the ignition and check the resistance in your plug wires, but i dont think that is your problem. One definate problem that i think you should change is the computer b/c nothing is going to work right with the wrong computer. Also if the car stops cranking and all you smell is fuel then you have probably just flooded out the cylinder and you could have almost hydrolocked the motor. so check out those sensors and check to see if the EGR valve is still stuck open, there are so many things that it could be just start testing the sensors. Another thing that you might check if it is idling rough is the IAC. You may actually have a serious vaccum leak as well so check your hoses and your gaskets around the intake manifold.

[crzycav86]

oh ya stupid me..i was so concerned with the compression test i forgot to do it right...i didnt step on the gas on the floor hehe...well i guess ill try again tomorrow...

Don't forget to have the engine warm up too. Otherwise the piston rings won't be expanded to spec, and you'll have excess blowby, and lower compression.
