Default um Uh-oh

Ok guys. I had the LIM off for the port job. I went to inspect the Pushrods and noticed one was loose. ( Last one on the right if you were facing the front of the engine.) Enough to wiggle it and spin it . I noticed a tick in my car before I took it apart. What do you think it is Lifter, Rocker or spring?

The pushrod should have very little play in, but a little play none the less. The OEM lifters loose pressure extremely fast. The longer the car has sat the more play/slop you will have.

Rotate the crank over a few times, most if not all of your P/Rs should have some play. And all should be very similar to the others.

If you feel uncomfortable with it, or feel you have an extreme ammount of play, buy a good set of 04+ lifters from Ed M. [email protected] .

Buickman104 and I Laughed hysterically when we read that.

Back on topic.

This is the only one with play, all others are taught. I am assuming I need the LIM off to change the Lifters. I have never done that before and believe it is out of my mechanical abilities.

Glad I could entertain you.


Remove LIM, remove rockers, pull out rods, remove some sort of lifter keeper thingy don't know what to call it, pull out lifters, out in new lifters soaked in oil, put in rods, out on rockers, LIM... everything else.

Most difficult thing is torquing everything, IMO. It'* tedious.

Shouldn't there be a little play in there? Room for heat expansion? Unless the cylinder is in its intake or exhaust stroke, of course.

With a solid lifter, yes.
With a hydraulic lifter, no. The hydraulic lifters are designed to compensate for just such things. The real benefit is they are quieter and lower maintenance.
