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

250 I-6

What do I have to do to keep the oil from leaking around the inspection plates on the left and right sides of the engine? I would be better off throwing oil at the outside of my engine than putting any in, that seems to where it ends up anyways. I know about the warping and gasket shift, but I didn't think that it would be a problem since I got new plates and gaskets. This is the third time I have had to get after this same problem.

On an unrelated note, how much would it be to rebuild an SM465? I think I am going to keep it and also add a Gear Vendors OD, instead of a 700R4.

Let me know what you think...

I always did lifter covers like valve covers, with yellow 3M holding the gasket to the cover, and Permatex liquid (#3 or Super 300) on the block side. Flanges must be straight, including the area under the bolt seals. You did put the seals under the bolts, right?

Yeah I did. Seems like all this thing does is leak. I got under it the other day to see what I would be POR-15ing in the rear frame, the metal is pretty clean. Well considering it has about an inch or so of old oil, I bet it is pristine....
