NLTS cost me my headgasket

steviek · #1 03-30-2009, 02:43 PM

I'm really f'en pissed right now. My car was running beautifully and I had never used nlts before. I say what the heck lets try it out. It worked the first time I tried it just took a little getting used to. The second time I try it foot is mashed on the pedal engage my clutch and then the Knock cel light flashes I lay off. Didn't think anything was wrong went to the gas station. Filled up still didnt know anything was wrong see the front of my car and there is coolant on the floor. Start it up and its white smoke and the sweet smell of your ass is ****** mixed with oil. Bring it home car is beginning to overheat. fill up the coolant. take out my spark plug. Compressed air into the cylinder and the water is shooting out like a ******* geyser.

I'm just so peeved right now.

On the bright side I have been putting off my INtake manifold install and now its the perfect chance.

Blown head gaskets suck. I've been there plenty of forgettable times. Sounds like you have an excuse to make it fun though. What intake manifold did you get?

How did it do that though? I think I just don't understand the feature well enough

Basically when you go to shift gears stay on the throttle and push the clutch in. The computer sees the clutch is in and cuts fuel/spark until you release the clutch. So all power is lost from the motor just like you left off but air continues to circulate and is not released so when you let go of the clutch the boost has only dropped a few psi and will come back super quick.

I cant see how that caused a HG to blow. Are you sure it wasn't getting ready to blow anyways? Did you log the run with link?

So you got that much knock when you pushed the clutch in or when it was released? It sounds like you are saying when you pushed it in you started getting knock and then it blew. That doesn't make much sence. The motor shouldn't have much load on it so it shouldn't knock. How much have you increased the timing with the meth?

I know I agree with you it doesn't make sense and I can't explain it either. I'm kinda devastated right now but its the truth. IT had a little knock less than 2 degrees up until when I shifted (remember this is just testing the nlts function out) then I disengage the clutch (wot) the nlts activates rpm level off but knock shoots up. KNock led flashes I get off the throttle but its too late car is smoking.

I should have it done by next week or maybe this week hopefully
its already in motion.

got the cometic head gastket (mls) and doing the IM so should be interesting.

see that red line that goes down thats the clutch switch thats when the NLTS gets activated.... correspond that with the green KNock line and hmm :S

SilvrEclipse · #14 03-31-2009, 08:48 AM

Thats weird. I looked over the log for a few minutes. It seems your timing dropped and fuel cut out when you pushed the clutch so there should be no way the motor knocked. Guess you wont be trying that anymore. I do it with MS and it works fine. Keeps boost up between shifts so I bet it would help 1/4 times some. Have you posted it on the link forums to see what they say?

steviek · #15 03-31-2009, 02:21 PM

yea I did

i engaged the NLTS about 100rpm too early but that wouldn't have the effect on the knock. The admins seem to think that there was a possible boost/vac/boost extremely quick situation which may have caused it to blow out.

Yea I don't think I'll be using that feature .... unless someone else gives me there car to practice on lol.
