if there was an oil problem the damage is done and it will only get worse

 

I dont believe all of the cars that are having this problem have an oil problem. The damage is caused by constant pressure on the end of the drive shaft. The stiffer the clutch the more the pressure. The longer you sit at the stop light with your foot on the clutch the longer the damaging pressure is there.

Not pushing in the clutch on startup does also seem to be a good idea.

 

Except for the hundreds/thousands/tens of thousands of S2000s that do all those without any crankwalk.

It's likely a mix of various problems, with the clutch having little to no bearing (no pun intended) on the issue. Bearings are made to tolerances, crankshafts are made to tolerances. When a crankshaft at the limit of it's tolerances is mated to a bearing at the limit of it's tolerances with the oil problems the F20C was notorious for (upgraded banjo bolts and burning of copious amounts of oil), it's easy to see where just a little low oil pressure combined with bad luck (regarding the tolerances of the parts involved) is more likely to result in crankwalk than a clutch that has been used for literally millions of miles by other S2000s with no ill effects.

 

Well LJ got back to me and measured the play. It is at .012-.013. He says he's gonna see how the oil looks in a little bit here.


Btw for you debaters this car in particular has never had any oil issues. Always checked on a weekly basis when I pumped gas into this car. Always perfect. Oil was changed very often as well.

 

You bought the car with the clutch already in it I thought you said so can't really say the previous owner didn't starve it for oil?

Anyways looks like your tolerances might be less than the service limit someone posted

 

Who knows though. Lets see what happens.

At these tolerances would pulling it for new bearings be a safe measure? Save it before it gets out of hand?

 

Your tolerances are within spec and right where my buddies was and he is making 680 whp on e85 with no issues. You should also be fine.

 

Thanks for the boost of confidence. I think I will be picking up a spare bottom end in the mean time anyways. Throw pistons and rods in that sucker. And if this one does let loose I got a back up.

 

There you go.....Rock that motor out until it gives, which I doubt it will with LJ tuning it and then just put the other one in later.

 

clutch, trans, turbo setup back on.

Waiting on some fluids, interior to be put back in, E85 to hit the stations and will be ready to try it out on the dyno. Crossing my fingers
