1. Did you leave it uncovered outside in the rain? 2. Did you reuse your old head gasket or buy a new one? 3. Did you check to ensure that the block or head wasn't warped? 4. Were there any cracks in the deck of the block that are extreme? 5. Does the head have any cracks in it that would allow water in the cylinders? Reccomendations in order: 1. Even if you left it uncovered in the rain, unless it was a deluge water should not enter the intake and exhaust ports. There are 4 drain cappilaries in the bottom of the exhaust/intake manifold that are designed to prevent water from flooding the engine. These are usually rusted closed and you will need to clean them out as well as the valley that the water collects in. 2. If you reused the old head gasket then it's probably not going to seal. Once it gets crushed to fit the deck and head it usually won't reseal as well if removed. 3. If the head or deck of the block is warped then you will have a tough time getting it to seal until you resurface the offending part. If the warpage is bad it just wont seal and you will indeed flood all of your cylinders. Check this with a straightedge. Be sure to do the head too. 4. These blocks are prone to freeze cracking due to the lack of sufficient freeze plugs on the side of the block as well as from negligence from former owners who did not add the appropriate 50/50 mix of antifreeze to the coolant. Cracks aren't bad, just weld the ones on the outside up and all will be well. Cracks on the deck aren't bad either unless they span more than 3/16" apart close to the sleeves. Something like this is perfectly acceptable. [IMG]http://img.photobucket.com/albums/v425/EZFEED/a37526.jpg[/IMG] 5. Cracks in the head can be tricky. If you find a crack, use a cutoff wheel and grind a channel in it the weld it up. For your problem be sure to check for any cracks from the water ports to the combustion chambers. Hope this helps!!!!! Pat
