Now throw into this the different push-rod lengths used and their ability to be assembled into the wrong engine. Think VALVE-TRAIN GEOMETRY.

The FE and MEL had similar maladies.

Hey, thanks for the heads up! When I take the spring off for the new seals I will give it the “wiggle test”.

Well, I’m done. I pulled the spring today and cant budge that valve. It had some black rubbery goo kind of like carbon but not hard. I was able to scrape it off with my fingernail. It was on the guide and the stem.

Whatever it is I suspect that’s what’s hanging it up. I put on a positive seal and buttoned things back up. No smoke at all for the first minute. Still running kind of rough at times. Once I took it on the road though it started smoking again. I think the head needs to come off and it needs to be cleaned. I’m tapping out at this time.

On a separate note I adjusted the valves on that side and it sounds real nice lol.

Thanks again for all your help. I’m sad I can’t fix it myself, but “A man’s got to know his limitations”

Good news. I got the valve unstuck and she runs again!

The facility that was going to fix the truck had a month and a half before they could even get the truck in. Two days ago I said “screw it” and opened it up again. Sprayed some PB Blaster on the stem and let it sit for a half hour. Gave the valve a few whacks with a hammer and a wooden dowel and it started moving. More PB Blaster. A few more whacks and good to go! I couldn’t believe it. Put her together and she runs.

Thought you guys would want to know. Thanks for your help!

Guess you didn't know your limitations, you conquered it!

Actually, what you did is correct and leads to no need for head R&R.

I wonder if the black goop you described was what was left of a failed umbrella seal?

Most likely. It was a bit rubbery and not hard like carbon. I will plan on replacing them all this winter just to be safe.
