Valve springs removal tool method

[d124716]

GEN 2

Can anyone recommend a tool / method to remove valve springs without removing the head. I am planning to pressurize the cylinder to keep the valves closed however, currently have no method for compressing the springs to remove keepers.

Also, does anyone know if the rocker studs are 3/8 or 7/16 or nether? I saw a proform tool and it is compatible with 3/8 or 7/16 studs but I have no idea if my studs are ether of those sizes.

Thank you!

You could also bring each cylinder to TDC but obviously you can only work on 1 cylinder at a time plus the valve could rotate too.

Personally I would not remove a spring without each cylinder (one at a time) your working on isn't at TDC AND pressurized.
Valve Seals?

It's pretty difficult to keep the piston at TDC when you pressurize the cylinder, it goes to BDC in a hurry.

I've wondered it one of these cheap LS compressors would work, maybe with a little modification.

Cut down on the pressure. I always put the piston on TDC in fear the valve will drop. I also give a light tap on the top side of retainer to free it up before compressing.
Just what I do anyways...

And put the car in gear and on the ground. Additional resistance to engine turning.

That makes sense... seals are good, trying to remove springs to test them. Chasing some odd knocking and someone suggested testing springs for being tired.

these do look promising, I was hoping someone had direct experience with a tool that they used.... I do have a "basic" mill and can modify parts somewhat if needed.

You could try one of these on head spring testers.

I never liked screwing in ot the head stud for fear of stripping it and causing a mess... I made a modified tool years ago to do valve springs.. it works good (even in hard to reach places).

I was able to use one of compressors on a Gen3 with a little grinding on 2 bolt holes (see photo).
