GM makes the top engine cleaner part number 50001 as I recall, it is about $5 for a quart. This stuff is magic on carbon. Bring the cylinder causing problem up to TDC, then pour this stuff in injector hole and let sit over night. See if the carbon is not all dissolved.
Note you will want to change oil after this. Also if the cylinder does have carbon it might be time to change the valve guide seals. I had this problem on one glow plug once, but I just kept twisting and pulling until it came out.

If so, does the glow plug have to be removed before you unscrew the prechamber? Thanks -Dave Walton 94 S350, 99 E300 On 12/31/05, redghost <[EMAIL PROTECTED]> wrote: > Tried to fix the mess in Cleo.
