alum to alum

I have M/T aluminum valve covers and 1/2" spacers. I want to bond them together permanently to avoid using 2 sets of gaskets. Have looked on the "net" and everything is so expensive, plus I want to be sure that anything I buy will withstand the heat. Besides two sets of gaskets are 'fugly' .

JB Weld maybe ?

I've not had the best luck with JB weld , but I think it might have been in the preparation. I'll probably use it, thanks.

There is a 2 part system called "5 minute epoxy". Devcon is the manufacturer. Good stuff!

If you bond it to the cover having well cleaned surfaces with "the right stuff" being sure to allow it a full week to dry, you will have no issues. Cut off the excess after it dries with a razor blade.

Or some 3m yellow weather adhesive for weather stripping

Duck tape it Terry.

I guess you have considered different "tall" valve covers?

I saw a t.v. commercial for that Mighty Putty it's gotta be good.Guy glued a hard hat on his head and is hanging from a steel beam.

Yes, but my M/T's look so 'right' on the '64 Galaxie.

Okay, sand w/60 grit paper and clean with brake fluid. Find the right stuff, JB Weld or the epoxy or the mighty putty (I'll check them out). Clamp and let cure for 1 week.
Thanks a lot guys .

Something else to consider. I used to paint a lot of Harley engine parts and because the aluminum was so porous the paint would start to blister after they got hot from the oil trapped in the castings. To solve the problem we would clean them then put them in the oven for about an hour at 450 degrees, let them cool and clean them with brake clean. Problem solved

The valve covers are in vgood shape, thanks for the tip.

I've got a set of those M/T's Terry. Pretty cool covers.

I have 2 sets, bought both of them at the Super Swap

Picked up some JB Weld Marine Weld, it's the only JBW that lists Aluminum in the Applications.
