How do I remove valve springs?

[talontsi01]

Do I have to make a special tool like this one? - http://www.dsmtuners.com/forums/showthread.php?t=161173&highlight=spring+retainer

Or - Is there some way to take them off without?

lay a rag over top of the valve keeper, place the head on a level flat surface, place a socket that will not be big enough to go over top of the keeper on the top of the spring keeper, smack the socket with a hammer (dont beat on it hard), remove rag and collect the valve collets, then remove valve

Ummm.... Well that can get the valve keepers off. But then you are still going to need a valve spring compressor to put them back in. Just make the one with the C-Clamp. I did and it's not to bad. Total costed me $15. Just be sure the put some rubber on the bottom clamp that touches the head so you don't mar anything.

Or you can just go to autozone and buy a valve spring compressor for 20 bux and do it right.

To bad those $20 valve spring compressors won't work for the 4G63 head. I bought 3 different spring compressors and none of them will work due to the tight pocket the springs are in. I've seen a few that looked like the bolted to the head and compressed the spring with a jackscrew type socket which would work with the head on the motor. Pretty smooth. But the home made spring compressor will work just fine as well and not cost you a lot if you have the head off..

you probably should'nt reply to this since you have never had a 4g63 head apart (obviously), no the regular valve spring compressors will not work, i use one that is made for sport bikes, but it's pricey if you are only going to use it once.

Thanks for the responses.

I'm actually getting my head machined, so I'm leaving my valves/valve springs on the head.

www.plymouthlaser.com is a great website on how ot build the C clamp for hte valve springs.

That's how I used to do it at work every day.

Its cheap, its easy. If you don't have the means to build one yourself and don't want to spend stupid amounts of money on something you are hopefully only going to use once, this is what you need.

Ive had equal sucess using a tool like this, they sell them at home depot and you dont have to modify the tool at all to use it.you still need the O2 socket. This clamp actually wraps around the entire head similar to a valve spring compressor.

Yeah that looks like it would work alright. Might have to add a different handle on it so it'll be a bit easier to compress the spring, but useable non the less...

 

[killab443]

surprisingly the handle is very easy to turn to compress the springs. You slide the clamp down the bar until you touch the back of the o2 socket, then you screw the clamp down.

i always use an adjustable pneumatic valve spring compressor, but i had to throw a 3 inch peice of 1'' tubing on the mill and notch it out and use it as an adapter on the end of the spring compressor because the valves are so tight in there and the depth at which the valves are at. ive done enough of them that i just tack welded the peice to the end of the spring compressor.
