Oil Leak - The 1947 - Present Chevrolet & GMC Truck Message Board Network

toddtheodd · 01-09-2010, 11:24 AM

So...
I know there is a hole in the front of the 350 block by the fuel pump that if you don't have a bolt in it, will leak oil.
Is there something like that on the back driver's side of the block? Like maybe where some clutch stuff bolts to the block? (zbar?)
I ask because I am SOOOO not finding this oil leak, and I know it is coming down the block from somewhere, to dribble down the oil filter and also to dribble down the transmission where it connects to the block.
It's not a bad leak, but it's annoying to have a nice beautiful motor that leaks.

Maybe leaking from the intake manifold or oil pressure line.

valve covers?

Already checked the oil pressure line, and it was loose, but is good now (oil leak was reduced...)

I don't think it's the valve covers, because there isn't any oil on the heads. I checked the heads too, and it's not coming from there either...
