All cylinders filling with water

Oh boy...

Good way to distort the deck.

ARP kind of knows why they recommend certain procedures. How's the stud going to come loose? The nut you are tightening is turning the same direction as driving the stud into the block.

Did you ever identify where the water intrusion originated from?

Is this the solid lifters on the hyd cam deal too?

Granted I didn't read all 9 pages of this monster thread (just skimmed a few pages)...but THIS (see bold print above) should have been a clue right off the bat!! I remember the other thread about your engine builder and some of his "out of the box" ideas. Did you ask him how he accomplished this task of filling all 8 cylinders with water? Did you tell him you wanted a Marine motor :mrgreen:.

Sorry for your loss, that has to be frustrating. My advice would be to get an engine building book, read it, and build it yourself.
