The Stovebolt Site Forums The Shop Area Engine Shop cold valve adjustment 235-solid lifters

I'm setting the valves after replacing the engine. Just had the engine out so the truck could be blasted.

I thought I recalled a cold adjust procedure..something like bringing cyl 1 up to TDC and gapping the valves...then moving on the other cylinders somehow..I must have been dreaming it..none of my books or online manuals discuss it..They simply say heat the up and gap while running..which I've in the past.

Anyone heard of a cold procedure?

Thanks,

Keith

Have you done a Search on valve lash adjustments?

What your describing will work. Just make sure both valves on the cylinder are fully closed. Right after the intake closes.
There is a procedure that involves less turning of the engine. Where you can set several valves at once. I don't remember how it is done. Maybe some one will step in and describe it.

I found the prodedure in the Tech Tips.

I can take a hint Dave-Yes I am lazy..thanks

Thanks Cleon-Will check it out-Appreciate the hustle

I used Oly's method. Seemed to work great.

Thanks again..and thanks Oly.

Here is another very well explained and written adjustment procedure....

I have to comment on the above writeup at www.speedprint etc.
First to be correct, I think the adjustment for the solid lifters should be done at "UDC" or Upper Dead centre, as marked on the flywheel. The steel ball is not at UDc but it is close to it.

Second: I don't have a manual here for the hydraulics but I am sure that it is more than 1/4 turn and personally I do that with it runnung. I suggest going past where you want it and then backing off to the correct turn count. This is to be sure that the lifter will not jam in the bore.

Third: The 235/261 hydraulic lfters do not click at idle. Also, the engine oil pressure only fills the lifter, and the lift force is created by the reaction of the piston in the lifter bore. The early Poweglide 235s had low pressure oil systems with hydraulic lifters.

Back to the main question: How do I adjust the valves on a cold engine. The answer is to adjust them the same as hot and then recheck when it is hot.
