Issues with Milky oil
« on: September 07, 2016, 08:47:14 AM »
Hey guys,

Having an issue with my 455...rebuilt the engine before the season, it has a torker manifold a xe274 comp cam and its bored .30 over has exhaust logs. took it out in June got the milky oil issues...replaced the intake gasket and the head gaskets (thought it was the intake gasket, had a water trail in the front part of the intake valley) and I installed a pressure relief valve...set at 10psi. did all that then I ran it on the hose...no issues and then took it out to lost lake the sunday before labor day weekend...no water in the oil Did some good short runs. Took it to needles for labor day weekend...launched it (sat on the trailer for a minute or two) then did a good 8 or 10 minute run before I took it back to the beach...milk shaked after that run (saw it cause it came out the breathers on the valve covers). What could this be...the oil temp was pretty hot felt it on the dip stick (don't have a oil temp gauge) engine didn't get past 110.

The front water plate on the engine I've seen and had water leaking in there from gasket.  Just something to check.

Do a leak down test on cooling system... Make sure it holds pressure

Took the water pump cover off...looks like it was leaking thru one of the bottom mount bolts, there was water on the bolt. Going to redo the timing cover gasket also then pressure test the system just incase.
