What are you guys using for leaky cometics? I have a small leak between the 3 and 5 cylinder. This is my first go around with cometics so i don't really know what to use. Thanks, Jesse

My W5's did the same thing once I got a few heat cycles in, it stopped leaking. Is this a new build I hope????????? I have had sucess with the Moroso ceramic engine sealer it will seal up anything

Yes, it is a new build with W5's also. I've only heat cycled it a few times, but it didn't start leaking unitl the last time a run it. I'm shooting fro a test and tune next weekend so a hope i can get it fixed.

My W5's leaked before I even fired the engine. No gasget sealer. It stopped leaking after about 2-3 minutes running. Not uncommon. They stopped leaking before I gave it the sealer treatment........
Damn! I dropped my change.............

since nobody has asked yet, have you backed off one bolt/stud at a time and retorqued them yet. often times that solves the problem. what was the torque # you used initially and what kind of block?

Yes, i've retorqued the studs and i'm at 90lbs with them. This is on a stock 340 block, with super smooth finishes on both the heads and block, we also drilled the rivets and sprayed coppercoat between the layers and used silicone around the water jackets. I was really hoping not to add anything, but i guess i have to. Funny thing though, they only leak when the car is running, not when the engine is cold. Thanks for the help guys, Jesse

That's interesting, i did not pay attention to that, my heads are a later casting so i bet they are slotted, thanks for bringing that to my attention, Jesse
