Comp Cams Valve Spring Compressor Has anyone used the Comp compressor?
http://www.jegs.com/i/Comp-Cams/249/...ductId=1433000
There doesn't seem to be much info on it anywhere. It looks like it might be easier than the Crane compressor that everyone seems to like.
Just looking for a review before I spend over $100 on a spring compressor.
Thanks,
Josh
Here is what they say about it:
The easy-to-use, custom design of the new COMP Cams Valve Spring Compressor for LS Engines enables the effortless removal of either one or two valve springs at a time, without the hassle of first having to remove the rocker stand or any of the other installed rockers. The tool works on all GM Gen III/IV LS-type engines, both with cylinder heads installed or with the cylinder heads off. The simple design facilitates easy usage in vehicles where other tools are incapable of reaching the tight spaces. This innovative Valve Spring Compressor is a must have for all LS engine builders and enthusiasts.
I'll be doing a cam and springs on a 99 c5

I prefer this one:

Only reason is that it uses a stud and nut to compress the spring. The comp makes you turn the bolt. When the threads start to die in the Crane style, you simply replace the stud and nut. Go to Ace Hardware and 5 minutes later you're in business. When the threads fail on the Comp unit, you're done. Either replace or helicoil.

Good points, I think I'm going to go with the Crane unit. That Jegs one in your link looks like a knock off of the Crane Cams spring compressor.
Thanks for the info!

30 seconds with a bench grinder will solve the bolt issue with the first tool.
I'd question using it on big springs though.
I won't normally buy an import but Crane really did everyone a favor by charging at least 5x the real price for that tool.
I'd rather build my own than spend that much.
The LSM version uses an acme thread on the stud so you'd have to order a replacement online for it.

I bought that tool and didn't care for it much. I like my Crane tool much better. Wound up trading it in to my Matco guy for something else.
The premise behind the tool doesn't really make sense. If you're changing springs, all the rockers/stands have to come off anyway. Doing 1 cylinder at a time while leaving everything else assembled makes absolutely no sense IMO. Especially if you're using TDC method to hold the valves up (I always do), then you're fighting spring pressure on all the other rockers/springs.
F that. The crane tool is far superior.

The Comp Tool Works Great as long as you dont use their bolts...
Just use 2 rocker bolts instead of the ones they supply and all is good
also.. if you have .700 lift valve springs like I do... you have to work a little to get the valve springs in....if it were only a1/4 taller of a tool..LOL
you can use the tool with the rocker plates or the 2 little spacers they provide... I prefer to use the spacers as it seems to sit better that way.
