Well, yet again another update. I was able to put the engine back on the stand, and remove the pan. I left the block off and head installed so I can continue to pressurize the block, and see where that crack is

here is what I discovered...time to start looking for an used engine
Mercruiser 3.0 internal cracked block - YouTube

and the crank bearings are toast

I have disassembled the entire engine today, nothing left but an empty block!
I needed to take out some frustrations lol

I will be working another engine this coming weekend for a friend. I will be replacing the head gasket, timing chain, ect, ect.. on a 2004 Ecotec 2.2 double OHV, has a misfire in cylinder 3. I have narrowed it down to a possible burnt exhaust valve, cracked head, warped head....we shall see

I will make some decent cash from the repair, and will put that towards another engine
