Cylinder head epoxy?????
 

I had to modify an oil passage on my aluminum head. A small part of the head surface goes beyond the block. Maening I'll have to fill it with something To stop an oil leak. This is an oil drainback passage not a pressure passage.
I have to seal an area about 1/2 inch square by about .070's deep. This is on the head to block surface of the head. Don't want to weld it because the head is finished and don't want to resurface it.
. There isn't a lot of heat there its right next to the water jacket. What type of epoxy should I use? Or should I just use rtv sealant?

JB Weld. I've used the stuff many times and it holds. It withstands heat and liquids with no problems. Clean it good...mix the stuff up and fill the area and after it sets up a short while you can shape it close.....after it sets completely (24 hours) sand it or file it flat.....

Also Rich, the Moroso 2 part A and B epoxy is really good!

Hi Woodro.....how are you? I never tried the Moroso stuff but have seen others say it works good too. Devcon also makes all kinds of epoxies that work well. What do you think of the rules changes for next year? I should be at Atco right now but my trailer is down at the moment and I have a day with my son planned for tomorrow.....We are going to a Yankee game in NY.......

This

is the best stuff I have ever seen or used.
Does not crumble or deteriorate like JB Weld over time.
Expensive but well worth it.
