My /5 is leaking oil from a few oil-pan holes. I've determined this by observation over a period of days. The push rod seals are leaking as well, but there is definitely oil getting past the bolt threads.
I know that the oil pan bolt-holes are "through" holes.
This started recently with a) an oil change, b) a new pan gasket, and c) installation of stainless steel bolts (sequentially torqued in three steps).
I strongly suspect that the new stainless fasteners are to blame; possibly a slight difference in "specifiation" allowing more major-diameter clearance(?).
Has anyone else experienced this situation (leak after stainless bolt installation)?
Two possible fixes:
a) drain the oil, drop the pan, clean holes, reinstall with new gasket using appropriate thread compound on stainless bolts.
b) replace with the original steel bolts (if I can find 'em...
) WITHOUT thread sealant, to see if the leak stops with the carbon steel OEM bolts (indicating that the stainless bolts were indeed "out of spec").
c) implement total-loss oil system
d) none of the above
