Just built a tunnel hull jet with 500 horse 502 engine and a american legand pump with droop snoot and place divertor. still in the break in period and it has blown the gasket between the jet and the snoot. What is the best way to seal this? Also the person who built the engine did not install a pcv valve, instead they just put in breather caps, I was going to install a pcv valve what are your thoughts? Thanks
