Thread: oil pan gasket replacement

Tweet

Are you dead sure it is not coming from above, running down to the pan/block joint, and then finding a path down the side of your pan? I chased a leak on my new 347 including changing the pan gasket and finally found problems with my valve covers (no baffles on the breather connections, poor fit to the heads). A new pair of valve covers and it has been dry as a bone, so far.

Auto parts stores sell a dye kit and a black light for tracing oil,coolant,and A/C leaks.Makes finding the source of the leak pretty easy.After finding the leak,you change the oil/filter.

I think your right

"dead middle of pan" ......(look at pic)

pan would not leak oil up on the oil pan rail setting there. less if there a rust hole there is a clip on oil pan pass side were gm holds the trans line they will rust thru there .other then that it top of engine oil leaking down .or fule pump /plate . valve covers . intake rails .oil sender .front seal . bad damper seal cut . no front bolt in fuel hole. not pluging the oil pump rod hole .crank case not vented....

the leak looks like this!!!!!!!!!!



running front to back!

thanks
