Model T Ford Forum: Forum 2015: Valve adjustment
Top of pagePrevious messageNext messageBottom of page Link to this message  By john aquina on Saturday, September 12, 2015 - 12:08 pm:

I am trying to adjust the valves on my engine. I put a feeler gauge in one of the valves(.015) and it was swimming!. I tried turning the nut, but it did not help. It seemed like the valve guide was spinning. It has one flat side, but I don't have room to get a wrench on it. I bought this from a guy that said it was completely rebuilt. It has never run. Any suggestions?

My TT's were like that, I had to turn the engine over until it pushed the valve up and then adjust, took several tries. On mine past owner had put adjustable valves, but did not machine the block. So the adjusters would go down into the hole and you could not git to them. It was a pain, but I got it, good luck.

Turn the engine over with the hand crank until the lifter is raised. You may need to use two thin wrenches. In the raised position you will be able turn the bolt in the tappet.

ya, those can be a pain in the
As stated before, turn the engine with the crank until the lifter is all the way up.
Then hold the lifter with one wrench while you turn the top nut up with another. Turn it about one flat, then turn the engine until the lifter is all the way down and recheck the clearance.
I would shoot for about .010". .012" would be ok too. .015 will probably be noisy.
You can tell when the lifter is all the way down by watching for its opposite lifter to be all the way up.
It's a nasty job, but somebody has to do it.
At least you won't have to take the valve out and get a longer one!

Each flat of the bolt = about .006. Turn so the next flat come around and you will have opened or closed the gap by about .006. If you need to go .003 just turn the bolt 1/2 a flat. ETC
