im looking for some ideas as to how i have water in my left cylinders of v8 engine. im getting ready to pull the manifold, riser and head from that side. what could be the cause of this. water jackets, heads,?????? i had taken boat out and it ran pretty good but near end of an hour plus run it became hard to start and i ended up burning starter up trying to restart.so i brung boat home and it sat untouched for 4 days. now on the 4th day when replacment starter showed up i installed. at this time engine seemed liked it didnt want to turn over very easy. then on 3rd turn of the key i heard a deep metal clunk, and at that time i stopped and was like that did not sound so good. im thinking a broken rod but not sure yet. but anyway at that time i pulled one of the spark plugs and water just come pouring out. now at this time im scrapping my heart up off the bottom of the boats floor. but i went ahead and unscrewed drain plugs on manifolds and risers and then all the plugs and turned motor over to push water out. motor turned over but did not sound so hot. anyway thats where i stand as of right now. im thinking of going out there now and sprying some pb blaster in the cylinders and cranking over a few times. i know this is going to lead to removeal of engine but any ideas of to the cause is great. ive got my ideas but other insight is what im also looking for. im thinking something with the heads. i had ran engine several times in a 55 gal. before i took it out in the bay and had no problems. granted it did not reach the temps. that i got it to out on the bay. but when i had it running on the water in drum it had water flowing through it with no appernt leaks or problems. could it of been thed salt water that i left sitting in it for 4 days after the starter. im going out now to start ripping apart i guess.
