Im worried about a crack in the block somewhere too. Machine shop said they have no way to check an aluminum block for cracks. However, None of the pistons were steam cleaned, and there was no water in the oil, no milky mixture in the pan or any milky deposits anywhere in the heads or valley etc. However, when driving it you could hear the sloshing sound in the dash and when looking into the coolant reservoir it did put off bubbles at a fairly steady pace. I really expected a bad gasket or steam cleaned piston or a slipped liner and I found none of the above. Only a trashed crank and rod bearings. Everything else really doesn't look that bad. The sloshing and steady stream of bubbles really make me think the was a leak in the cooling system somewhere, but now I'm at a loss

Rover Doctor, if you have your heads off, can you tell just by looking at the liners if they have dropped? Just curious, it sounds like you've got lots of experience with these engines. Thanks for your time!

Well, the best thing to do would be to pressure test the block at this point. You just have to seal off the four ends of the block faces and the water pump housing as far as I know, then put some pressure to it and see what you get. Check out the video on youtube from the singing camel rover shop. I think it's called "slipped sleeve syndrome" if you want to see what it will look like if you're losing pressure. Good Luck!

I thought about that, but I read of other guys who pressuere tested blocks and they were fine, but then installed them in the car and ran them and still had block problems/leakage. Problem seems that if the block passes the test it doesn't really tell you anything. Only that it might be ok but no gaurantee
