timing

1995 GMC YUKON


my problem is setting the timing after i r/r the intake gasket .now the dist rotor is set about 45degrees away from tdc i set the crank pullet at TDC and got the blow out from my #1 cylinder but im still 45degrees off (about)a mechanic told me to take the distributer out and stick a long screwdriver down the shaft and rotate the shaft for the distributer but i cant get it to move much more and it's still off a very little.I'm getting very frustrated can you walk me through it ,anyone?

Look at this article: http://www.chevyhiperformance.com/howto/45673/index.html

Scroll down and look for "if the engine was disturbed" and read on from there.

thank you for your reply to my posting ,unfortonently my other mechanic came last night and set the timing for me .it looks like i may have damaged a lifter possibly a vave ,but not likely .I'm on my way out to do a compresson test now.thanks again,SONNY.
