    did you tq everything to the right specs ? round 1 ,22lbs . round 2, 90* . round 3 90* ? Clean all that old gasket off?

    Dont worry the side of my block has a lil oil , not as much as it had b4 i did my HG.

    yeah, you just fucked up. if anything its not as tight as it was b4. Your going to need to get a new set of head bolts, they are like 20-30 shipped. This is a very easy job since your not removing the head. Dont go cheap around this kind of stuff.

    the threads on head bolts stretch when torque'd down. you CANNOT re-use them.

    i guess technically you could, but it will most likely result in a poor'r running engine and possible internal damage.

    So you asked for our opinion, and went against what everyone said?

    So, this slowed the leak considerably but did not stop it all the way. I think I can live with it till I have time to fix it right.

    I performed #2 .

    I have not removed any head bolts yet...this motor is still intact, I am opening it up tomorrow.
    It is at my buddies garage so it will be stone cold when we start.

    It could have warped when u removed the old head bolts. Did u take them off in the right order and slow?

    Shit. Still gonna try the simplest thing first and replace the bolts. I have a spare head if need be.

    Thanks guys, It was a long time BMW mechanic who suggested to me that I could re-torque my old bolts...I am gonna go ahead and order new ones.

    I agree that the chance of success is low, but it could be worth a shot. Headbolt sets are pretty cheap - around $20.

    You can change the bolts, but as previously stated they can't be re-torqued. However, the chances of success for this are pretty low. The odds are that you won't fix this w/o replacing the gasket and probably having the head decked.
