DDog,

If the pushrod is noticeably lower, your lifter has probably popped out. With a good light you should be able to look through the hole and see whether the lifter is there or not. I was able to reuse my lifter.

Barry is correct, it may be possible to reset it without pulling the manifold with the proper tools and a lot of patience. On my engine, there is a splash pan over the valley, so it would have been nearly impossible for me to do it without pulling the manifold, particularly because it was the #4 cylinder, which is the furthest from the distributor hole. With your issue on #5, you may be able to reset it. Second hole from the left should be intake.

As a precaution, if you haven't already done so, it might be prudent to buy new intake gaskets, just in case. I've found they are not always in stock at the local parts store.

Good-luck. Are you planning on going to San Marcos at the end of the month?
