Does your S30 leak oil?

Mine weeps. I should just replace the gasket, but I'll get to it when I get to it...

It did, until I tightened the previously finger-tight oil pan bolts.

Not even a weep. I think that it's a factory original 1978 engine, looks like it's never had work done on it.

Mine was leaking badly when I got it. Turns out the timing cover was loose. With each bolt tightened to 8 lb/ft I haven't seen a drop of oil in my CLEAN garage.

For what its worth, my '71 was tight as a drum as well.

Dry as a bone. Engine rebuilt & I replaced rear seal on tranny as a precaution. Original diff is still tight and there are no records of anything being done to it. (I have all records).

I'm hoping my rebuilt 5-speed doesn't leak after I install it!

Interesting. I guess I should overhaul the Z soon, with new gaskets. Not too familiar with This car.

I have a leak at the rear main seal. Been leaking for at least the last 14 years. Yes I have the parts to fix it, just to many other demands on my time.

73 Z, 136000 mi. Leaked a little til I put teflon tape on the oil pan plug and torqued the pan bolts. Also tightened the trans cooler line clamps, and torqued trans pan bolts. Saw some oil by a front cover bolt that didn't drip to the ground though- need to torque those.

FWIW, when i attended the 2011 convention in Savannah, they gave everyone a plastic mat to put under the cars that were in the convention center. When the judging was done, and the day was over, and the S30 group pulled their plastic mats out from under the cars, NOT ONE had a drop of oil on it. I was so proud.
