OK, after 41 years of owning my ?36 Pontiac I am going to attempt a valve adjustment on my own. Here?s what I think I know about how to do it:
? Don?t even try to adjust them when hot (the exhaust manifold is right on top of them and I would surely fry my arms).
? Leaving them a little loose is better than getting them too tight and risk burning them.
? Adjust them .002? over when cold. My specs are 9-11 hot, so I?m thinking 12 would be a good middle setting.
The problem I haven?t figured out is how to know when the valves are in the right position for adjustment. #1 is easy: find TDC (when both valves are closed, the lifters free and the gap the largest), then adjust. But how do you accurately and easily find TDC on the other five cylinders? Turn the engine over by hand and watch the lifters until they seem to be in the right position? (tedious) Use a compression gauge? Seems like it would be a lot easier if they had marked all cylinder TDCs on the flywheel.
How did they do it in the old days? My Flat Rate manual says the time allotted to this job was 30 minutes. I?ll be lucky to get one done in that time I?m sure!
