    I pulled out my distributor to replace the manifold and all went well until I tried to put the distributor back in. it seemed like it was about 1/2 inch from sitting flush with the manifold. do I just need to jiggle it and force it or am I missing something. also, is there anything special I need to do when I put the distributor back in? or should everything be good to go? thanks.
    by the way the manifold was a holley tbi manifold for a GM.

    You have a common problem. You are, most likely, a tooth off and are not lining up with the oil pump correctly.

    Pull it out, part way, with one hand on the base and one on the rotor. Then turn the rotor one tooth at a time untill it drops in.

    I am assuming you know how to find TDC /forums/images/graemlins/thumb.gif

    Don't bother finding TDC. Put it in the way it came out. Start it 1/8 turn from where you want it, drop it in. Hold your hand on it and have a buddy bump the starter and it'll drop in.

    Well, if you marked the distributor, and have not turned the engine over, you do not need to find Top Dead Center. You can just line up your marks...

    If you just pulled the distributor without paying attention to it then you need to find TDC to get it timed right.

    Any manual will describe how to do it.

    I'll sum up the procedure with little detail.

    You need the #1 piston to be at the top of its travel on the compression stroke (That is TDC). At TDC, you point the rotor to the wire going to the #1 cylinder (or close to it) and install the distributor. From there, you can use a timing gun to adjust the distributor correctly.

    Just make sure you are on the compression stroke and not the exhaust stroke. If you go 180 degrees out, fire will shoot out the carb /forums/images/graemlins/smile.gif /forums/images/graemlins/weld.gif /forums/images/graemlins/smile.gif

    the bvump trick i dont understand how that can work, unless you didnt move the crank or oil pump drive shaft

    in which case theres no point in bumping the engine over, i dont see how it works

    i always check for TDC and set on zero degrees on timign taba nd move the oil pump shaft so the slot is pointing at #1 cylinder then i drop in the dizzy

    everyone has to learn at some point or another on how to drop a chevy distributor in and set #1 TDC and set position of the oil pump drive rod

    It works for me . Most of the time the engine isn't disturbed . It just falls in and meshes . Just a simple intake swap or gasket change should be fine /forums/images/graemlins/dunno.gif

    I did mark exactly how the dist. line up. I was just worried that maybe the shaft turned a little, but it would have only turned a little which means I should be able to drop it in and set timing from that right?

    thats the i always do it. No bumping, no hassles. Turn it a bit until you get it pointed at TDC(after setting though)
