Can the push rods be removed just by unbolting he rockers and pulling them out with no ill effects? Seems to me like you could do that. On of the rockers is REAL loose when there is no pressure on the rocker from the push rod and I want to be sure the push rod is not bent. The truck has been sitting for two weeks. Would one think the lifter is not pumped up? I ran it all around about 10 or 12 times to do a compression test but it's still loose.
So I'm reviving this post a little. I finally got the new bolts(one was broken) from Ford to bolt down my rocker arms. As I stated earlier in this post, the fourth rocker from the fire wall on the passenger side is real loose. Considerably more loose than any of the other rockers. I am thinking to verify that it is a lifter that needs to be pumped up, I will do the following:
1. leave the rocker cover off.
2. install the injector pump.
3. leave the glow plugs and injectors out.
4. hook up a set of hoses tied together with tees from the end of the injector lines into a bucket.
5. crank the engine over until fuel runs out the hoses, meaning the pump and lines are purged.
6. by this time the lifters should all be pumped up and I can verify the push rods tighten up.
It should of pumped up when you ran it. Change it out. The valve isn't bent or a bad spring is there?
I'm not sure what you mean by "it should have pumped up when you ran it". It hasn't been started for nearly four weeks now. What my question is: With the glow plugs out, if I crank the engine over enough times to purge a new injector pump and lines, would that be enough revolutions to pump up a lifter if it drained?
Couldn't hurt, why not try it? Give it a few seconds of cranking and see what happens.
Just leave the valve covers off until you are sure it's working good -- you can run an engine with them off no issues, and you can see of things move correctly.
Sorry Eric, I thought I read you had started it for a few. I read to many threads I guess. I think with the valve covers off if you start it you should get lots of oil! It will take a lot of turning to get oil up there and lifter pumped up with out a start.
