There was a chunk of injector O-ring that got lost in the manifold, I can no longer smell burnt rubber, generally, and figured it had burnt off by now.... But it could be sitting on a valve?

I know I have bad valve stem guides/seals, I get that heavy smoke after letting off the throttle, and then giving it throttle, like when shifting or letting it sit and then racing it. But again, mostly fixed with heavy oil.

If you mean the pcv hose, like a bit of exhaust I'd say, and it does blow a (even and rythmical, not uneven and sputtery, like the exhaust) bit. I took off the breather filter and put it back on the intake to see if it was loosing enough to blowby to confuse the computer, but it didn't fix it. Anyway, that IS exhaust, right? it's blowby, which I have plenty of, as I have 50psi lower than a new motors compression.

The little line on top of my carbon canister is broken, I thought it was the vaccum one, but neither the canister side of hose has any movement/suction.... Been that way for a long time, anyways.

One thing I noticed is if I unplugged the bung on the intake manifold to re-attach the pcv hose, there was no difference, and it used to almost kill the engine.....

That's an interesting problem. It's not choking out. I wonder if your MAF is bad and it's kind of adapted to it not returning a signal... It's so hard to diagnose without being there. Where are you, btw?

West tx.

I got a maf code, cleaned it with carb cleaner, having heard that this would work (hopefully deposits are the worst possible outcome, and it didn't eat anything, or whatever), and even though the code went away, later, with maf cleaner to make sure that wasen't this problem.

And I did 3 injectors that must have been fine, and mucked up and ruined the originals with vice grips, they where really in there..... I thought it had something to do with a new injector and the rest being old, but it runs the damn same.

I punched a few holes in the top plate of my ecu, and re-mounted the diagnostic screw so the ECU doesn't need to be removed..... So far, it's easily been worth it. :whistle:

Also, I checked my o2 sensor with the test described in the FSM. it may not go lean/rich quite often enough that it would be okay, say for dealership maintenance back in the day, but it's obviously working well enough.

I want to think the problem is vaccum somewhere, and it's adjusted to it enough that it doesn't notice my unplugged pcv.... Or an egr or iacv problem? I'm a bit confused on how to play with this, though, fsm did NOT help, maybe I didn't know where to look. And the buggers expensive....

*edit*along with no mafs code (its got 55, all good) it's also not in that 2400rpm limp mode.

So i did a search and googled but didnt find the answer. I was wondering if anyone new off hand if there is a seat belt buckle from other vehicles that would match up with my 95 belts? My 92 ones dont match nor do 90 gtst ones. Any help would be appreciated kinda in a rush to haver done for an inspection.

Is it damaged in a way that could not be explained away as normal wear and tear, or age related failure? Or did you tamper with/remove it?

Well the situation is i have a 95 i picked up for the motor and subframe. Nuthen wrong with the seatbelts. My buddy just grabbed the 90 gtst and we had to swap the belts for the inspection. I know we could have stitched the tags but he wanted to just try the belts out and they fit ok. He made em work. The whole time we were stripping the 95's interior we didnt even noticed it had no buckles. Now he needs some buckles that the belts will click into.

Ps That was a very interesting read indeed. Good info to know in that link.

I've heard all manner of hate for bondo.... What's a good filler for standard stuff, from little chips up to massive damage?

And for going over sun eroded s13 bumpers, what type of filler should be used?

What should I do to the whole bumper before prime/paint, anything, to protect the plastic and make it stick right? Special paints/primers needed?

Planning on tearing apart the front end in a few weeks, bashing out and filling all the dings, painting, and putting it together strait.

Any general tips or lectures for someone trying to learn to do my own body work?

*edit* also, is there a forum or thread devoted to 240 body work/paint, where I can ask questions or see pictures? I decided I'm probably actually rolling rustoleum, maybe cream and tan 2 tone or something-but I'm trying to figure out what to do with the A pillars(hatch, so they have black vinyl to flow smoothly into the quarter window), and if I match them, if I'm deleting the grove above the doorjamb, where to put the color changing line, and if it involves rubstripping or deleting it.

Brake and clutch say on the caps. PS fluid is dexron for s13, dunno about yours though, cause I think they phased dexron out and s14 uses higher pressure I read.... transmission/diff are in the FSM. I forget the specs, but I know royal purple gear oil is safe for both.....

If you do gear oil, I suggest filling the transmission from inside the car, with the amount the FSM says, by using the little precision tip on a gear oil bottle in the shifter, and do the diff by using duct tape to hold a tube (I used bike inner tube) in the filler hole, and holding the other end and bottle ABOVE the bumper level, to pour it in-I tried one of those little oil squeeze pumps, it was total junk, didn't even screw onto the bottle right, and spilled gear oil on me before I decided to find another way.

transmission- GL4 75w90 or 75w140. I use Redline MT90 badass fluid.
Diff- Whatever you want in there. 75w90 80w90 75w140... it doesn't much matter.
Brake- DOT 3 or DOT 4

Hey all, I'm slowly learning about all this auto mechanics stuff so I apologize in advance for "annoying" questions: I own a 1990 Nissan 240sx, automatic, and has a KA24E engine. What would I need to swap it out to a KA24DE? Also, would it matter if I swap my engine for a KA24DE that came from a manual 240sx? Thanks in advance for tips/advice.

What is the best chip and remap to use on my 98 240sx SE?
I plan to do a remap to eliminate my catalytic converters soon, and I would like to know what are the best chips/remaps to use and where to acquire them.
Cost is not an issue for me.

Should be able to search to find all the details.

Would need the DE engine, wiring harness, ECU, intake, exhaust, powersteering setup, and transmission.

AT has a steel insert on the crank for the torque converter, the pilot bushing from the MT engine would need to be removed and that steel insert put on, if you were going to remain AT. But if wanting AT on the DE engine you'd need an AT transmission from a DE car as mention above, E and DE AT trannys aren't compatible (MT trannys are).

JWT and Enthalpy have the best reputations for ECU re-flashes. JWT has been around the longest that I know of.

Personally, I'd go with him. If you have any questions, I'm sure he/we can answer them for you. Good luck!

Thanks Biggie for the heads up. I think it'll be easier if I just swap for another used KA24E as a temporary fix for now. I need a DD for at least 2 more years.

I've got a vacuum line under my throttle body with no idea where it goes. It's by itself, not part of the PAIRC valve or charcoal canister group, at least where the hose attaches. Somebody know what this is/for?

EDIT: NM, based on advanceauto's website they are the same, for future reference.

Quick Thermostat Question:

My friend has a Nismo thermostat for the SOHC KA24E stanza (91 I think). Is the thermostat the same as the KA24E 240SX engine thermostat? Thanks in advance. I tried courtesypars but that nissan dealer doesn't have the stanza listed anymore :-/

Here is a picture of the hard vacuum line I was referring to(the one circled in green). From this picture it appears to go into the throttle body, is that correct?http://s1170.photobucket.com/albums/r52 ... 011107.jpg

I've also got the same hose with red tape as the picture, but mine has a T on it with a larger diameter and really short hose coming off the T. Where does this larger hose go? I am also assuming that his white taped buddy is supposed to have a similar hose to the same place.http://s1170.photobucket.com/albums/r52 ... AG0184.jpg

Good question... I want to say some are affiliated with the charcoal canister. I'll have to look at mine at some point to give you a better answer.

I suppose that depends on where you are.

NICO has classifieds here:
nissan-for-sale.html

240s are all over craigslist and autotrader, etc.
