stuck valve collet help

joeboomer999 · Aug 9, 2012

Hi,
went to take out the intake valves. Compressed the spring and one collet came out as should but the other is real stuck.
tried the "smack it with a socket" trick but still nothing.
any help would be appreciated.
Thanks

Head off or on?

With the valve spring compressor in place, the collet should easily clear and drop out without fail. You do have a spring compressor dont you?

That i do, and thats what happened to the one side. This side just moves downwards with the spring/collar

Hit it with some compressed air.

I assume you are using the big C-clamp type of spring compressor so not exactly sure how that downward movement is happening. I'd tighten as much as you dare then smack the top retainer with a big punch to shock it loose.

push the spring retainer away from the collect as it will some times put a load to one side . when this happens you cannot remove the collet.

Just compressed the spring and shot it with 140psi. not a budge

I was originally using that type but was unhappy with the evenness of the pressure it supplied so switched a straight top type.
When i was using the c clamp style i did try that though, but no such luck

This was my original thought on what was happening but it does not seem to be. I installed the compressor to the side slightly to put a little more pressure pulling it away but still no movement.

Can you get a punch on it and give it a tap away from the retainer of which it seem to be stuck in. You should be able to spin the assembly to get better access.

have tried this lightly. Was worried of putting to much force on it though.

with comparison to the other intake valve the stuck collet is much farther down in the cap hence why its being such a bugga i guess.
The valve stem is pretty well flush with the top of the cap.
Would it be a bad idea to gently tap the top of the valve stem and see if i can work it threw that way? (the valve is being replaced anyways)
thanks for all your help so far.

presumeably its stuck on the VALVE ? wind the compressor so its at least half exposed , way in . flick out with screwdriver .

IF its stuck on the cap , lean something solid adjacent so a tap has the cap firmly supported . to jar it loose .If you use a hammer , you still got to be scientific .

Dings burrs or suchlike on collets are a big no no . Whowever , if youre replaceing the Valve , Cap, Collets & springs , a 8 in disc grinder will go through it like butter .
just watch how you aim it . :lol:

Sounds like the split keepers are totally wedged heavily between the collet and the valve stem.

As long as you are careful not to miss, the only success will be had from snugging down real well on your compressor then doing as suggested - smack the collet face with a rigid tool that can get in there to free it off. WD40 or other penetrant will help, spray it and tap tap tap, spray some more, get it to soak in, then smack it smartly. Make sure head is well supported so as not to break a fin.

Oh, yes, heat also helps...

Does it look like there is baked on oil? Or do you suspect a mechanical hang up like a scar on the collet? If it is stuck from baked on oil, I would spray it down with my favorite lube and set the heat gun up on it. If you are replacing springs you might be able to (carefully) reach in there with a cut off wheel on a Dremel and cut the coil so as to collapse the spring. Cut a number of pieces out and do the same on the inner spring. I am thinking this would be easier than cutting off the end of the valve!

Finally got it out. ended up fabricating a curved pick to go threw the spring and up into the retaining cap. While another person compressed the spring i gave the pick a sharp tap and the collet came right out.
Thanks for all the help.
