Trying to adjust the valves on my 71 3000 diesel, IT manual says to turn the engine till the TDC mark on the flywheel is lined up with the timing mark. I removed the inspection cover and found what I think are timing marks but they are numbers. I set it to '0' centered in the inspection hole (don't see a fixed timing mark). I don't think I have it set for #1 at TDC as some of the valves they say to adjust in both cases are still tight.
One valve that seems to be all the way closed is the #3 intake and it's way too tight, I gave up when I wasn't able to get a .011 feeler gauge in the gap.
1. Is there actually a "TDC" mark on the flywheel?
2. Trying to do this by myself using a remote switch to bump the starter. Is there an easier way to turn the engine over while on your back looking in the inspection hole? I did jog it with a screwdriver to get it right on the '0' mark but wouldn't care to turn it 180 using a screwdriver.
3. Do valves tighten up with wear? No way can I get a .016 gauge in any of the valves that seem closed.
Thanks..
