The valve covers on my 1965 365 horse motor look great (correct, blah, blah, blah), but the right side cover weeps oil, and is usually greasy after about 1 hour running time. What can I do to fix this annoyance. No, it isn't the gaskets----the block is dry, and the oil residue is on the upper side of the cover.

Re: Aluminum Valve Cover Porosity
Buy a can of spray Glyptal (paint/sealant for sealing porous castings and insulating electrical windings). I'ved used it for years on rotating equipment and it's inert to hot lube oil, diesel and gasoline. Wipe the inside of the covers down with lacquer thinner and spray on two coats. Many engine builders us it to slick-up the inside of their blocks and to trap any sand which might shake out.Comment

Re: Aluminum Valve Cover Porosity
Terry excellent solution. never thought of glyptal, which would be a lot easier to apply than the RIGHT STUFF. thanks, mikeComment

Which Glyptal product?
Terry,
Glyptal makes a bunch of different paint/primer products. Do you know which one is best for
the inside of valve covers? Is it the 1201A?
Thanks,

Re: Which Glyptal product?
I believe the current designation is INSUL-8 or Sul-8-Red Aerosol Spray. I just asked for "red Glyptal". They also make it in pint cans - used to anyway.Comment

Insul-8 is made by Eifco, I think
Terry,
I think Insul-8 red aerosol is a product made by Eifco, not Glyptal.

gylptal
was originally sold by GE. they may have been the developers and any one who worked with large industrial vacuum systems kept it handy to seal leaks till there was time to fix the leaks right.Comment
