I'm New Here And I have A Simple Question Thread, (No Flaming Allowed)

[needfaster240]

yeah, could be MAF, or bad injector. Hell, it could even be an O2 sensor. Try pulling your sparkplugs and see if they all look the same, or if one of them is blacker than the rest (indicating one of your injectors is bad).

can the air filter effect the maf readings?? i noticed its kinda ditry.

[PapaSmurf2k3]

Nope, not that badly.

[unibody_s13]

hey whats up guys! i also new here... i have a quick question that ive been trying to solve for 4 months now after my sr and LSD swap...

i have a s13 freshly swapped and i cant figure out why my rear tires are losing traction... it happens when i turn my steering L or R from a stop and releasing the clutch or turning on a corner. rear wheel spins and the car shakes from the rear. i feel that its coming more from the right rear and cant figure out whats wrong. i checked everything from the torque settings, fluids, replaced all bushings and even returned some parts to its stock part but no luck!!!it feels like inner wheel spins... bad!

here are the things ive done with my car... s13 sr20det blacktop swapLSD from s14SPL diff bushingDSS aluminum dstokico blue shocks and tien springs300zx brake upgrade f & rmegan front sway bartien tie rodsOEM front control armsgreddy fmichks ssqv

thanks in advance and hoping sum1 can help me!!!

[PapaSmurf2k3]

Wow, it sounds like you have a welded diff. Are you sure of the condition of your LSD?

hello i have a 240 sx with a sr20 swap did i had done to it not lon a go but now the engine sounds very bad and i hear a knoking noise in the engine, even when its in neutral.It sounds like the cam shaft but am not sure/if it is where is a good place to take it to repair ? I live in santa ana CA please let me know of any good shops around the area .

[PapaSmurf2k3]

Any shop should be able to diagnose that for you, and then tell you what it is.

[alfsnissan]

Ok, looking for help again. Had some noise coming from the rear when I made left hand turns. Changed the passenger half shaft and still has a noise. Could the drive shaft be binding up? Could the wheel bearing be doing it. The wheel has no movement so that should rule out wheel bearing correct? Thanks.

[PapaSmurf2k3]

Not always. Usually when there is a bad wheel bearing, there will be some play (jack the car up and try and grab the suspect wheel by the top and the bottom and try and rock it).

Can you describe the noise? Also, if you swerve the car back and forth, does it always happen when you turn left? If so, all signs point to wheel bearing. Good time for a 5 lug swap

OK, jacked it up and tried to move the wheel. No movement that I could see or feel. The noise is a deep thunking, Knocking sound. Its hard to tell... I feel it behind the console but the sound is near the wheel. Its hard to pin point the area for both. The sound happens everytime I turn left.... not a light left turn but semi sharp turns to the left it will make the noise. Hope this helps.

I have been wanting to do a 5 lug swap but what really does that intell. I know I need the hubs for the back, but as far as the brakes, what happens? The front, you need all different spindles? And for brake there, what do you need? thanks

[PapaSmurf2k3]

You'd just get everything from an S14 SE and it would all bolt right up.

So it is just one thunk? If so, its not a wheel bearing. Wheel bearing problems are long sustained noises that usually get louder the more you load that side of the vehicle. You might have a bad bushing or something. Check sway bar end links/brackets.

How hard would it be to find all of that?

No, the noise will stay as long as I hold the turn.

[PapaSmurf2k3]

I haven't done a wheel bearing in a 240, but I'm guessing it comes pre-pressed in the hub. So you'll get a hub/bearing assembly that has the studs and everything.

Sometimes NICO has advertiser specials on 5 lug conversions (which include new wheel bearings).

[alfsnissan]

So, your telling me that in your opinion, the wheel bearing needs to be changed? You think thats all that it could be? Could I have recieved another bad shaft?

[PapaSmurf2k3]

Its pretty tough for a shaft to be bad. I'd say a wheel bearing would go bad way before a shaft goes bad. If it is sustained noise, like you say it is, then yeah, I vote wheel bearing. Just make sure you replace the right one. I can't say 100% for sure though, as I'm not there to diagnose it myself.

[alfsnissan]

[QUOTE=PapaSmurf2k3]Just make sure you replace the right one.QUOTE]

What do you mean?

[PapaSmurf2k3]

I mean make sure you do the right wheel. Shouldn't be hard if you know exactly where the sound was coming from, but make sure its not "throwing its voice" if you know what I mean. Did you check the other side for wheel play as well?

[alfsnissan]

Yes, I checked both sides. I'm pretty sure thats its the pass. rear. The way money is right now I cant do the 5lug swap, do you think it would be better to just change the hub or have a new bearing pressed?

is it only in neutral or is itall the time??? does it get worse when accellerted or seem to go away?did you do the swap or did you have it done?

You would probably be better off changing the whole hub. You would need to bring everything to a garage/machine shop to get the bearing pressed out, and the new one pressed in anyway. In which case, you run the possibility of screwing up the bearing itself, and you don't save very much money at all.

[alfsnissan]

Papa. You wouldn't happen to know what this is called. Its part of the AC that opens and closes the heat vent. The arm is broke and this is part of why my hea ts not working. ANYONE???

[PapaSmurf2k3]

uhhh... not the official name. Maybe blower vent control, or something along those lines. You'll probably have to do some searching through the FSM. I have the link to them in my sig.

[alfsnissan]

Once again, thank you. I found it. I'm glad there are people out there willing to help like you do. Merry Christmas.

[Nashville Slider]

I own a 92 240sx 4lug. what all is required to convert it to 5ug?

[PapaSmurf2k3]

Pretty sure you just need the 5 lug hubs. You will remove the 4lug hubs/wheel bearings from the spindle and bolt on the 5 lug.

[hazukijitsu]

PapaSmurf!!! two questions.

First, My speedometer stopped working, then the next day it works on and off. I noticed that the mileage isnt moving either, so my cluster isnt showing how fast im going or counting my mileage, everything else is fine. I pulled out the speed sensor, hooked it to a voltage regulator, turned the little gear and its showing a signal. Any Ideas?

Also My 240sx seems to overheat when I exit the freeway and stop. I drive on the streets stop and go with no problem. It happened about 2 times. I drive on the freeway going about 70 mph for about an hour, I exit the freeway and wait at a light for about a min or so and my car overheats. But once I start driving with no stops, the car temp go back to normal

Thanks Papa Smurf

I'm not Smurf but I'll give it a try.

1. I seem to be having the same problem. I too checked my speed sensor and turned it and sure enough, the speedo needle moved fine. The conclusion me and my dad came to is it's not the speed sensor, it's the gear in the transmission that turns the speed sensor. Yeah, sucks if that's what it is.

2. Well since there is much more airflow when you are driving that could be what is keeping your engine from overheating. Either way, sounds like you have a cooling issue. Make sure you don't have any disconnected hoses or any leaks and go from there.

I'm sure Smurf will be here tomorrow to give more assistance. G'day to ya.

Not sure about the first but, the second I think I have a theory on that. On the freeway, you’re building up a lot of heat going that fast and at that rpm. Not going to bother the car because the air is moving right under the car moving the heat out. You come to a stop, all that heat builds up in the engine bay and brings the temp up. Does that make since?

[PapaSmurf2k3]

The stock cooling system is more than ample enough to provide adequate cooling for those conditions. Something is probably wrong with your stock cooling system. One of your fans might be out, or your radiator could be starting to rot out and doesn't cool like it used to. Lastly, you could be low on coolant. Give these a check (make sure you check coolant in the radiator when the car is cold), and let us know. If it isn't any of these, you may have to replace your water pump (easy job).
