I am learning how to adjust my valves for the first time on my new 1981 LUV 4WD with the 2.2L Isuzu diesel engine and have two questions.

1. Should I believe the valve clearances on an Isuzu sticker on the hood of the vehicle or the clearances in the Series 11 Shop Supplement (which contains the diesel engine info?)

On the hood it says the valve lash (cold) should be 0.016 (0.4MM limit) for both intake and exhaust valves. In the shop manual it says the intake valve clearances are 0.039-0.068 and the exhaust clearances are 0.064-0.093 (0.20 limits for both.)

One exhaust valve was in a position where we could check it, and it was at 0.016.

BTW, I have no idea if this is the original hood although I see no evidence of a front-end collision (I'm no expert, of course, but one of my Mercedes 300DTs is a front end wreck and I know what that looks like.) I don't know if this is the original engine, either, although with the odometer only at 123k it would certainly seem like it should be the original.

2. What's the best way to turn this engine? There doesn't seem to be much space to work in at the front of the engine or from underneath.

Thank you!

I am not used to forums and see now that I posted this in the wrong place. I'm going to re-post it over on the Diesel area
