Rear main seal leak on 1996 Tahoe 5.7

That is beautiful

Back in 69-70 hot rod got a stock corvair (140-4 speed) to run low 14's with just some bolt on's. One thing people forget is they did not need a bunch of horsepower. they only weighed 2500 lbs in coupe form.

Even after adding the V8 in the back seat my crown car was only 2700 because we took out weight elsewhere. BTW the car in the pic has over 500 HP.

For what it's worth brake fluid will swell rubber seals up and stop leaks sometimes. I have no Idea how it affects the engine oil, but it does swell seals and stop leaks. It has worked for me, but I've never tried it on anything I cared about.

Brake fluid won't just swell seals, it will balloon them until they are absolutely useless.
