Rear main seal
OK...have an oil leak. A pretty good one. 1997 Blazer 6cyl AWD sat over the weekend 3 days. Moved it and found oil under car. Not a whole lot but enough to notice. Looked under and looks like oil commming from the weep hole and the two rubber hoses where the engine and the transmission meet. Is this the dreaded main seal? I think it has been leaking for awhile because the whole underside of the engine has oil on it. Havnt looked hard yet for a leak from valve cover or not. Any advice would be great!

Usually It is the oil cooler lines. They go bad all the time. Never changed a rear main on these. Clean off the area real good and start it and watch it while it is running. It will be leaking around the hoses or the gasket set at the remote oil cooler mount at the block.

Re: Rear main seal
Look everywhere, it could be something as small as a valve cover gasket.
