Mcprodesign, I have always used silicone on the intake where it meets the block & see no problem with that. But silicone on the front cover, both sides of the oil pan gaskets, and trying to seal o rings with it is not cool. That's what was going on with these engines.

I have seen failures on the intake before ( oil leaks). They put silicone on the factory gaskets to the heads which I thought was weird, and then made the front and rear gasket with it..They caked it all over the dipstick and then used another stuff on all the pan gaskets and end seals.Gobbed it all over .. Funny thing.... When I took the engine apart. It had the equivelent to great stuff on the intake ( ends only) and nothing on any of the pan gaskets or or end seals. And the engine never leaked a drop.

They reused the timing cover seal and used an aftermarket 1 piece rear main seal.( even though we supplied them with all new factory quicksilver stuff i found for cheap on ebay). Morons i tell ya morons

Looking good Randy. Did you ever get straightened out with Ateco?

Yes

[ATTACH=CONFIG]538991[/ATTACH]Another step closer. The twins are almost dressed for the prom. Lol

Awesome

I think most marine valve covers want accept stud girdles,

Ive never had a failure out of crower stuff

The other engine builder to stay away from in that area is Entech out of Toronto... not a clue what they are doing other than ripping people off. The stuff that I have seen come out of their shop is unreal --- like a half assed Briggs and Stratton lawn mower shop! And charged big money to do it.

Randy -- I'm sorry you went through the Bullet crap -- hopefully your new builder is a different breed. Good Luck.
