im thinking on installing springs and retainers and i want to know more about them. i searched on here and all i have found was people who have already done it. i would like to know more facts about it and how it will help and if there is anything else i need to do when installing them. and maybe a how to

 

assuming you're not removing the head, you'll need a spring compressor, and a way to keep the valves from dropping (easiest way is to pressurize the combustion chamber, but im more of a fan of a mechanical stop of some kind)

 

I haven't on a cobalt, but when I changed the springs and retainers on my GTP I pressurized the cylinders and turned the crank pulley by hand until the piston in the cylinder I was working on was at TDC, that way If I lost pressure somehow I still had a chance of grabbing the valve without having to pull the head.

 

lol well it seems like im just gonna have to get someone to do it for me, cause i dont wanna mess anything up

 

I have a spring compressor tool, and a thread on RLF on how I did it (easy!), check it out and the compressor is for sale btw.
