Any body got any other ideas short of pulling the head for unsticking a vavle? going into 3rd week of auto trans fluid pb blaster tap tap tapp ,daily or more , tried the rope nothing, it is down and the spring hasn't moved even with pry bars in it . I don't think compressed air will work and i am not willing to load it with grease to try it . It was running but very rough until i pulled the valve cover , spose i could try that again ? ------------- Play on 38 B 49 WF , working on D14, D15 B10, Bee 12 B110. use 185 and 190 |

I would have pulled the head after the second try but I am always in a hurry when I get around to doing something even if it has been on my bucket list for years. One more thing you might try before pulling the head. If yo can compress the spring enough to remove the keepers you might put the keepers in the groove, grip it with vice grips and use a slide hammer to pull it up some so you can start working it up and down. If it is stuck because it is bent nothing will bring it up without moving the guide. If the spring is not fully compressed you can put a socket over the valve and hit it with a hammer and the keepers will fall out. Or maybe fly out so you need a rage over the spring if you don't have extra keepers. I bet this didn't help much.  Actually removing the head is not that big of a deal. You will need to buy a head gasket. |

I've done the slide-hammer trick in a pinch, but I'm with Dick- if it's stuck that much, you'll be best to just pop the head off... and while at it, pull and check each valve spring height and tension (probably have a weak one or two in there), wire brush each valve, scrub the stems clean, and make sure every guide is good (not loose or binding) all the pushrods and rockers are straight... clean out the chambers and ports. Many a 'tired worn-out' engine woke up for me after this process as a perfectly healthy, happy machine.
