    my thoghts on how to install my timing chain

    ok bare with me, long story short...

    broke timing belt .....Valves not bent ... the head is still on the block

    what i was thinking is i will rotate my crank so that the pistons are all midrange up the sleeve (hopefully i can do this i havent checked it out yet). then i would rotate the camshaft and get it to the position that i can lock the camshaft with the locking tool/drill bit....

    at that point what valves will be open?..if any..

    then i would bring the crankshaft around and lock it into its locking position.
    hopefully do all this by hand but i havent tried to rotate the cam yet. crank spins easy....

    Take a pictures of the cam gear. Its maybe in about the right place already. The valves will be closed when the camshaft lock tool is in place. The cam is easy to turn if you pull the rockershaft off. Just should use new bolts to reinstall.

    If the bottom case is off then the crank really doesn't spin all that easy. The crank will want to leave the crank bearings on one end and the opposite on the other and pretty much be a pain the whole time your trying to turn it.

    Please keep in mind that if something got caught up for enough revolution, something had to give somewhere I hope for your sake nothing is bent out of tolerance and that your timing chain took all the damage

    While you got it apart, I would go ahead and blueprint all parts and clearances just to be safe.

    ??? How are you holding 100 psi.
    A leak-down tester is a measuring instrument used to determine the condition of internal combustion engines by introducing compressed air into the cylinder and measuring the rate at which it leaks out.
