RE: Why did this happen
ORIGINAL: 1991LX5.0
Well a couple days ago i tried to start the car and it wouldn't turn over so i ended up finding out that the #2 cylinder was filled with water. I just pulled the heads off and this is what i found
This is the #2 cylinder and the exact same thing happened on the #3 cylinder. Does anyone have any idea what caused this? I scraped down the old gaskets very carefully and made sure the surface was very clean and i am also using head studs and followed the torquing sequence very carefully. Are their any tips you guys can give me for putting the new ones on. Is there any cleaner or anything I should wipe the surfaces down with before putting the new gaskets down?

RE: Why did this happen
All good advice, but also if you had enough water in the cylinder to prevent the engine from turning over, you had hydrostatic lock, and hydrostatic lock = very bad. Before you put it back together, pull your oil pan and check to make sure the rods on the cylinder(s) that had water in them are straight. Liquid can't be compressed, so when you try to crank it and compress the water, the energy has to go somewhere, which is 1 reason why rods are designed to bend and absord the energy, otherwise you break piston pin bosses/ring lands, cranksetc. It wouldn't be a bad idea to actually pull the piston(s) and do a visual inspection to make sure they're not cracked as well, and that the rings and ring lands are still good. If it looks fine but runs rough after you put it back together, then something is damaged(possibly a bent rod that you can't see). Let's hope your starter was too weak to actually do that though

Do not go with the Felpro lock wire gaskets. They are crap and you will have to remove extra material off the head if (when) they fail. I runthe Cometic gaskets (MLS - multi layer steel -Viton coated)and they have not failed me yet. www.cometic.com

RE: Why did this happen
I just got back inside, the heads are already on, if i would have read this before i would have gone with the cometic. I took a straight edge across the heads and they were dead straight i couldnt even get a feeler guage underneath the straight edge. I cleaned the heads and the block off much more than i did last timeI did overheat once when I had an air pocket in the system and i think that might have done it. Hopefully theese hold up. Thanks for the help guys. And idont thinkthe starter had enough power to do any damage. When i went to start the car i could hear it engage but it didnt do anything just click, click
