EA82 head problems

[rmgreer]

I recently picked up a GL Wagon that had been sitting for a "while". The previous owner had attempted to start and run before selling, but there were apparently some stuck valves. He had removed the valve covers and noted that the rocker arms had fallen from two cylinders. He said he had tried soaking the valve seals and running, getting it going on one cyl. only. When I opened the valve covers I realized that what he had in fact done was allow one of the lifters to come unseated and out of the bore in the head, which then was driven back into said bore by the cam and rolled the edge of the sleeve preventing the re-installation of the lifter.

  What I am wondering is: are these sleeves available to the average "Joe" and where would I find one? Also, would it be worth the time to remove and replace the sleeve myself or just give up and find an entire new head?

 

Thanks in advance...

You'll be replacing the heads. Lifter bore sleeves are not a serviceable part. Take a hard look at the engine overall - it may not be worth the effort.

Wow. How.m bad is it rolled?

 

I can't see it but Why not just plop it back down in there, maybe massage it a little if needed and run it? It just needs to sit there.

 

But yeah - install another head and carefully check the motor like he said.

Yeah, the link doesn't seem to work. If the lifter bore sleeve has been pulled or slipped out and damaged at the top, it's toast and as GD said, not serviceable. The bore has to be completely true and smooth or the lifter WILL bind up and seize especially after it gets warmed up. The damaged head is now junk. Yes, you could find a sleeve that could be machined to work and then installed, but the cost would be far greater than finding another set of heads or even an engine.

Well, as idosubaru said, it just needs to sit in there. The "lifter" does not move. It may rotate, but it is not necessary that it does so. The sleeve is only there to maintain a tight clearance around the "lifter" (In quotations because it's not really a lifter. It lifts nothing. It's a hydraulic lash adjuster, or HLA, for short), and control oil pressure and flow. It is not a bearing.

 

If you can clean up the roll with just a little file work, and get the HLA back in there, it's probably going to be OK. The only danger would be if the damage, or repair would be so bad, or so close to the oil galley that it would hemorrhage enough oil to lose substantial pressure. 

 

Me, I would clean it up enough to get it back in the bore and see how it ran, and what kind of oil pressure it had afterwards. If it's ok, go with it. If not, move on. And by "move on" I mean EJ. In one form or another.

a couple of heads in rebuildable shape should be easy to find.  just start with a better core since your rebuilding them anyway.

Scott is correct, I got ahead of myself... again. HLA's don't move up and down in the bore. I would still be a little concerned about it staying put in the bore and not walking back out due to engine vibration and causing an issue in the future. Once a sleeve like that gets free, it will move again. If you were set on attempting a repair, I would get everything clean with brake clean, apply some Loctite green sleeve locker to the outside edge of the sleeve where it is outside the bore, press it back in and wait 24 hours for it to cure. It won't come out again if you use the green Loctite. At least, not without using a torch. You'll want to debur it before doing this.
