So heres the deal. I had this loud knocking noise that came from my engine. Couldn't figure out why. Sounded like it was coming from my head. Thought it was maybe a rockerarm or something. Turned out good. I can't figure out why it was knocking. The noise would disappear whenever I would step on the clutch. Figured it was my throwout bearing but the people I asked said no it can't be. It's my rod bearings. So I take those out and they're fine. Anyone run into this problem at all? Car died on me at a stop sign and won't start up anymore. Help anyone?

 

hmmm u need to provide some more data.

ur description is somewhat confusing.

 

might be main bearings on the crank.

 

ouch, +1 to check crank

 

Thrust bearings. If it goes away whenever you step on the clutch, it's because you are placing pressure on the crankshaft via the PP/FW, and this is taking up any slack that has worked it the phenomenon called "crankwalk". You will have to replace those, and since you are at it, your main bearings/rod bearings may as well be replaced, too. Time for a rebuild.

The 2G 4G63 had this problem, as well as the EVO IV. Read this to know more about crankwalk. http://www.overbore.com/?go=Define.CrankWalk
