Plus, he pressure tested the manifolds. Only the risers were not tested under pressure. And they were eyeball leak tested at no pressure, which would still show most leaks, and all bad leaks. That block and heads need pressure tested.

just got off the phone. He said he went back to the head gaskets and found signs of both leaking. he didnt surface the heads cause they were new. Heads are getting surfaced and block checked as well. Block was pressure checked and is fine.

i need to get a new fuel pump. Had a holley mechanical. I saw the thread reccomending cv pumps. $500 aint in the cards unfortunatley.

I was running a mechanical fuel pump ( I think it was a Holley ) and it supported 650 HP - You don't need a high $ electric one.

I dunno why you feel you need to replace that pump. It just got oiled up real good. But if you insist, I'll pay for shipping and you can send the old one to me...I still want to hear he-or you-pressure tested that engine before it goes back in.

The builder told me he called holley about it and they told him it was shot and blew out the diaphram.

Everything will be checked before it goes back together for sure.

Ok. Motor is back together and in the boat. just for the heck of it i decided to pressure check again

no water in block. Room temp. Pump it up to 20# and it slowly leaks down. Could hear air hissing in the front of the motor. Started spraying soapy water around and discovered its leaking air at each flange on the crossover. Ive never noticed water leaking there before. Pulled the crossover back off and gaskets looked ok. The flange does have a slight warp to it.

Is this a problem? Its never leaked water before. Can i double gasket it or has to. be replaced? Never had this issue before?

Are you using any silicone or installing the gaskets dry ?

Installed dry.

Can your engine guy have it surfaced .
