Help....2001 5.0L EFI engine with approx. 250 hrs on engine. Always ran mint, no real engine issues over the last 5 yrs I have owned. Always winterize correctly (live on Long Island). This yr I replaced all exhaust manifolds, spacers, and risers (elbows) before putting in water this season. During my first run i noticed that my exhaust seemed louder than usual, hmmmm, also I noticed that at wake speed, less than 5 knots I had a lot of turbulence coming out the drive, water very "rough.choppy, instead of smooth flowing and sound..Engine still sounded great. All temps good. Next day I had same issue, opened up, temps good no issues other than at no wake speed still loud exhaust and turbulent water behind drive. (drive was down). Long story short I discovered water in my oil to the point it seeped out of dip stick tube. I have NO external block leaking, internal don't know....Can this be a exhaust manifold/spacer/riser issue?...The turbulance and loud exhaust is throwing me for a loop. I have no done a pressure test yet of the block....PS....I am having issues just finding the right fittings to isolate the cooling. I want to go through my stat housing via the temp sensor to apply pressure..Finding the right size plugs to block off the 2 water lines openings going to the bottom of each manifold ( i could "clamp" the lines, but not sure how good that would work) and then plug the raw water in and the circulating port is difficult getting right plug.....Anyway to find exact inside dimensions of the ports for the Thermostat housing for a 2001 5.0L EFI (TBI)?
