Thread: Valve spring air compressor tool

So after being BS'ed around by alot of shops/people who either dont know what their doing or wont do my rocker install im deciding to do it myself. I ve been looking at nothing but videos and found a specific video on youtube that shows how to do it.

YouTube - Valvespring replacement


- Which spark plug hole on each head do i plug it in?

- When im working on the certain head, Does it matter which spark plug hole i compress the air into or can it be any of the 3 holes?

- All 3 spark plugs must be removed before compressing the air into the heads correct?

- Is pulling the heads as easy as removing the supercharger?

You have to put pressure in the cylinder that you are doing the valves on. The air pressure keeps the valve from falling into the cylinder when you pop the locks off and remove the valve.

So it doesnt matter which spark plug hole i use on the cylinder head im working on?

Must all 3 spark plugs be removed?

You have to use the plug on the cylinder you are working on you can't just use one plug and do all six springs.

Yes i understand that but im asking which plug (out of the 3 plug holes) do i use? The left, middle or right? And should all 3 spark plugs be removed before working?

You remove them all, then switch the tool from cylinder to cylinder as you work.

Each plug corrisponds with each cylinder. 2 springs to each cylinder. what ever 2 springs your working on plug it in that hole
