Valve adjustment issues... when will this valve ever co-operate???
I've spent as much time on this one valve as I have on four other cylinders. I'm turning the nuts toward the left of the picture below (looking from the driver's-side, turning towards the timing chain). I've loosened it this much several times and it's STILL too tight (.35 mm is the exhaust spec I'm using).
What is going on? Am I turning it in the wrong direction? Something else wrong? It is loose enough for the intake specs -- so it's not crazy tight -- but this is an exhaust valve.

Cam lobe is pointing up right?
Is the rocker arm straight - doesn't look very straight in the picture but that could be an optical illusion. Are you holding the cap on top of the spring with the third spanner?

Cam lobe pointing right up at the oil feed tube per Roy's instructions.
Rocker arm appears straight. No, I don't have the third wrench. Is that the problem? I've been able to do all nine others without.

The ideal way is not to have the spring and valve rotate while doing the adjustment. That is what the third wrench is for. Reason being is the valve rotator beneath the spring could be worn and not able to spin the valve causing an uneven wear on the valve seat and stem. Once you rotate the valve, you disturb the position where it was wearing down on and the valve will not seat correctly. This valve seat wear could cause the adjustment to be used up.
Also the not so drastic, what stretch said above..^^^ .

It can be if the valve spins in the valve seat - the top nut seems like it is stuck!

 . I can still turn the bottom nut both ways. BTW, I realized that I broke a PP technicality by not specifying the engine -- OM617.952.

Are you bottoming out with the adjuster nut? Or you are just spinning the adjuster and lock nut and no movement is happening.
What I said earlier is a drastic case. Didn't mean to bring fear in the equation so early in the discussion.

Richard -- how could I tell if that is the case? How would I reseat the valve?

Hopefully Roy got you straightened out. But I suspect you are spinning the whole valve and not adjustment is being made.

This thread shows how to make the third wrench. http://www.peachparts.com/shopforum/diesel-discussion/180280-home-made-valve-adjustment-wrench-info.html Since several of my Hazet wrenches vanished. I choose to buy both a 27mm and 30mm box end wrench, and cut a 20mm slot to make custom line wrenches. .

It's always reassuring talking with Roy
. Yup, what I was calling the "bottom nut" was actually the middle nut and the 27 mm REAL bottom nut was stuck onto the middle one. Roy gave me instructions on making the third wrench myself, but I ended up using a screwdriver instead as shown in the picture. What a difference it was! I got it adjusted right off the bat.The red arrow points at the screwdriver tip...

Just be damned careful with screwdriver tip. As noted, I broke a valve guide screwing with that.
