I had a local engine shop rebuild my motor this year for me. The first time I took it out it seemed like it was way down on power, and was turning 700-800 fewer RPM's than it should've, then it locked up on me. When I tried to start it back up the next day, it blew watter out the left pipe. I had a neighbor who is also an engine guy come over to look at it and he found loose head bolts right over the cylinder that was full of water. So I took it back to the engine shop for them to check it for and repair any dammage. They said there was nothing physicaly wrong with any of the parts ar gaskets.
Now here's the fun part: They said that the bolts "somehow loosened up" when I started the motor, which led to the water in the cylinder! (I suppose I wasn't supposed to start it!)
Fun fact #2: There was a $300 bill waiting for me when I went to pick it back up!!!
They were actually trying to charge me for repairing what could have only been their mistake! If there were no broken parts or pieces, how else does water get into the cylinders? I had to threaten them with a lawsuit before they finally canceled the bill.
I guess my question is: have any of you ever herd of head bolts loosening up just by starting a rebuilt motor? These are ARP bolts, not junk. The thing was put under no stress until I took it to practice, and the problem was there from lap number one.

after a engine rebuild where I use new head bolts I alway's go back and re check the bolts after I break in the cam they tend to loosen up a little. when I use old bolts it's not so bad but I still check them.

They'll loosen up a little on some engines. We retorque all our head and intake bolts after the engine is broken in at the shop. That is a widely known standard practice.

I'd say it's time for a new engine builder...

Trust me, I've already found a new builder, and he's going to go through the motor FOR FREE to check the new work done by the old shop. The head bolts were new last season, so they should be fine. I can understand losing a couple of ft. lbs. of tork, but I just don't buy that they loosened up that much. (they were supposedly torked to 70#'s) Regardless, it seemed pretty s***y to me that they were not willing to back up their work. Especially when the new one will check someone else's for no charge.

Live and learn, I guess.

Thanks for the replies.
