Paul,
The instructions in the manual are easier to follow, but yeah, pretty much the same. I went into my garage and snapped a photo of the instructions in the Haynes Manual that I follow.

RYE, is your method of adjusting valves consistent with Alex’s? I suspect they are the same

Except for small, air-cooled engines that may have an automatic compression release mechanism built into the cam shaft (either in the cam grind or as a centrifugal device), I always taught my shop students that you can never go wrong by bringing each cylinder up to TDC-compression and then adjust the valves for that cylinder. There are often a variety of short-cuts where a manufacturer will tell you to adjust certain valves at TDC - Compression of #1 cylinder and then the rest of them at TDC – Exhaust #1 cylinder but those are engine specific. Most 4 cylinder engines have a firing order of 1-3-4-2, so if you see “valve rock” (exhaust closing, intake opening) on # 1 cylinder, you know that #4 is at TDC – compression and its valves can be adjusted. Then, turn the crankshaft a half turn ( total number of cylinders divided by 2), and adjust the next cylinder in the firing order which would be #2. Then 1. Then 3. Distributor rotor position on a gas engine will help you figure out who is at TDC – compression. Diesels don’t have that option, other than pump timing marks for #1 cylinder. Look in your shop manual for details.

Subject: [TR] Setting valves Procedure
Is there a universally excepted method by which to adjust the valves for A TR three? I know when I asked about this before that Randall sent me a link to a bunch of articles but I don’t think any of them concern setting The valves. Where can I learn to do this?
Thanks, Paul Dorsey TR three 1960
