Common oil leak areas?

[maomaonsx]

Can I take an informal poll of where have you discovered oil leaks on your NSX? I have seen some drips near the right side of the oil pan just yesterday at the track. When I first drove in the morning, I was trying to learn the track, there fore not driving very aggressive. There were only minor leaks. In my third session, I was pushing the car very hard, the leak increased quite a bit. So I ended my day early and came home. Anyone here can share your experience with oil leaks on your NSX?

The only leak I've had so far is from the rear Spool Valve the car has 82,000 miles on it and just had it serviced.

Spool valves and pan gasket on my 91. None of the leaks were very bad. Never enough to actually affect oil level. I never tracked the car or drove it very hard so I don't know if it would have increased as yours did.

Hmmmn... near right side of oil pan. Oil pressure increases as you drive harder, which explain increase leakage.Your oil filter,cooler base assembly is on the right side and oil pressure switch as well.I doubt it to be the oil pan gasket cause the oil prssure doesn't increase as great in the oil pan. But,pull your right rear wheel off to get a better view anyways. If it appears to come from a location no higher than the oil pan itself, it may easily be the front main crankshaft seal. The oil tends to leak from behind the timing belt cover and appears to be coming from where the oil pan meets the bottom of the oil pump housing/timing belt cover. The higher reving and increased loads on the crankshaft would induce leakage on this seal. The oil pump is directly behind the seal as well. Regardless, I think once you pull the wheel off you will easily see where it is coming from.Good Luck...
