water in cylinders

[bosavy]

i have a 1995 5.7 500 hours ,stay docked in a marina . if i let it sit for weeks engine will not turn over find water in cylinder. not always the same one mostly starboard side but have seen it on port. Any ideas? It has stainless steel risers and replace those gaskets last year without fixing the issue.tks .

Ayuh,... I'd guess you've got a Manifold problem,...

Pull 'em, 'n pressure test 'em...

Not many hours for a 16 year old engine. I agree with Bill, manifolds. If you want things to last longer, you gotta use the boat more.
