Bought a new impact socket from Lowe’s on the way home from work. And 2 seconds later everything was done.
those craftsman sockets are crap I guess.

So I’m obviously a moron or something bc I can’t figure this thing out. It doesn’t seem to compress the springs enough to get the retainers out. Am I doing something wrong here. I’m getting really frustrated with this whole thing now.

That’s back not conrpressed again didn’t want to leave it under tension. And that first pick was all the way down. I’m sure I’m doing something stupid but I just don’t get it

One thing I noticed is you should have some washers under those 2 allen head bolts because it kinda looks like the blue part is being pulled up at an angle. Is the plate compressing the springs hitting the blue part before springs are fully compressed?

with the nut loose you need to run the threaded rod all the way down until it bottoms out, then start tightening the nut and it should press down on the plate which will compress the springs and release the locks... the big washer probably needs to go under the nut, the smaller washer looks like it should go on the allen bolt on the right side (the one that is slotted)

Nope doesn’t remotely work. The way it’s facig which I consider upside down will compress a little bit not nearly enough.
The other way just rocks on the screw hole between the springs and can’t do anything at all. So friggen pissed off rigt now.

the first pic looked correct except needing a washer on the slotted hole and threading the rod down before tightening the nut... the tool I have is not exactly the same but very similar and it works fine

The blue base plate does look right in the first pic. Next the threaded rod goes into the base plate, then the compressor plate, large washer and finally the nut. Make sure you don't have a nut between the base plate and the compressor plate and also make sure the 2 mounting bolts aren't too long which would cause them to bottom out before the base plate is fully tightened down. In your pics it looks like the base plate is crooked. When you compress the top plate does it go all the way down until it is flush with the base plate?

Yeah so the conpression piece goes down and hits the blue piece and it’s not compressed down enough to come close to getting the retainers off. That’s why I think something is wrong

After looking at the pics I'm going to jump in here and offer up my 2 cents worth (probably wrong). I looked at my tool and it doesn't have the upward bevel on the vertical part of the "T" shaped base plate. It looks like this upward bevel on yours causes the compression plate to bottom out on the base plate before the springs are compressed enough to free up the retainers.Are you sure yours is for an LS engine? At any rate, may I suggest that you place a couple of spacers between the valve hats and the bottom of the compression plate? I think this would allow enough space to allow the springs to compress enough to clear the retainers from the valve stem. I would make sure there is a big enough hole in the washer to be able to access the retainers and the washers were wide enough to sit securely on the hats. Without being there (which I would like to be to give you a hand but I live 1200 miles away) I'd guess that 3/8" space would be sufficient. If not you could add more washers. Hopefully I wrote this clearly enough to help. Keep us posted on your progress!
