Lash hydraulic valves Chevy 250 292 Inline 6 cylinder 

Crazy how those motors keep running long after

Have an old USGI manual for military trucks that someone long ago wrote in pencil beside the 6 cylinder firing order "too young, too old, just right". I haven't forgotten that firing order since reading that.

No,because,while 1 is at intake,,6 is at exhaust.Camshaft wise,,that is.

Great to hear!

It’s little bit hard, but if you live in the usa or Canada it’s gonna be easy for you. The things you gonna deal with is the 1_power steering pump bracket 2_ transmission kick down bracket. Btw you can cut the ps bracket and reuse it with the regular head. 3_alternator bracket. You can use the same alternator bracket if ur engine got the older alternator bracket.

HALF PINT Same here. Didn’t explain how how he came to the first mark. Must be magical.

Yeah, he did. He says he set the engine to #1 TDC (look about 0:35 into the video), and he made a mark (the yellow line). The second mark is 1/3 around the balancer, and the third mark is 2/3s. You don't need to be exact, you just need the valves to be fully closed, which is on the base circle of the lobe. You can estimate the difference, or measure the circumference of the balancer and divide by 3. Technically, you don't have to do that. You can set the engine to #1 TDC, then set the #1 intake and exhaust, #2 intake, #3 exhaust, #4 intake, and #5 exhaust. Then rotate the crankshaft one full turn, then set #2 exhaust, #3 intake, #4 exhaust, #5 intake, and #6 intake and exhaust. Both methods work. Tom's way allows setting the valves in pairs (both intake and exhaust for each cylinder), and requires rotating the crank 5 additional times (1/3 of a revolution each time). The factory service manual way allows setting half the valves, then one full crank rotation, then setting the other half of the valves. Take your pick, which ever feels more natural to you.

I would probably estimate, then you can see the piston at the top through the spark plug hole pretty easily to confirm.

Nope. Older compcams

@@telowe2000 thank you!

Anything past zero lash preloads the lifter, doesn’t open the valve...

if you have solid lifters it will act as north west described, Tom's procedure is for hydraulic lifters

My 250 looks different than his. So I’m totally confused.

Thats right YouTUBE NOT YOUR FRIEND!

Why do you think they are needed? Pushrods are fully supported by the head. Geometry and alignment is fine.

Oh OK I was just wondering because I've seen them on so many motor's before especially when used with aluminum roller rocker's I didn't know the head supports proper push rod valve train geometry Bro sorry dude .
