Thread: oil leak

Tweet

Don't know what the hell is going on with my chevy but took it out this afternoon, ran it up to 100, held it there for 2 miles(if it blows, it blows) brought it back down to 65 and ran it there for 5 miles and parked it with no oil leak. Two weeks ago I rebuilt my 350th tranny and didn't put in a shift kit. With my high gears it seems to hold at 75 in 2nd gear before dropping into 3rd. Might have a pressure built up that one day which causes it to push the oil out the pan

Next time you change the oil put 5 quarts instead of 6 and I bet that leak stops.

hhhmmm very interesting......this sounds like the mysterious earl leak my motor had when it was in a family friends coupe....it started when the motor was 6 or 7 years old....oil all over the passenger side of motor and firewall when running at freeway speeds 65-70 or more.

I still have a couple months before i fire that motor up after a rebuild, we didnt find anything off or weird when taken apart, we assumed it was the timing cover, but i will make sure that i put a bolt in that motor mount hole.............good info in this thread
