    Now that i am finally able to turn some wrenches after my Shoulder surgery. I started pull parts off the motor to access the valves. I tried to get the motor running about 3 weeks ago, I could barely get it running and i decided to do a comrpession test. #1 - 75, #2- 0, #3 - 85, #4 - 95. So i knew i either had a stuck valve or a broken spring in #2, especially when the fuel mixture and oil was being shot back into the carb and made a nice oil slick on top of the carb.

    The culprit

    A bit of a gap between lifter and valve


    Besides being filthy in there i also found some antifreeze on the top of the valve adjustment screw

    So it looks like i have a leaking head gasket also. SOOOOOOO good thing i had the had gasket already. I am soaking the bolts to prepare to remove the manifolds and head.

    So looking at the cruddy valve galley, what would be a good course of action to clean it out? I know to plug the oil holes so crap doesnt get into the oil pan. Should i scrap or use brake cleaner? Pulling motor is not in the plans. Or should i just leave the gunk as is?

    Although I hate leaving things dirty like that if it was mine I probably would do just that. I'll bet that stuff would not come off easily. If you were going to pull the pan then I'd use anything that would get it clean.

    Yep. Next it will be connecting rods being inspected, and since you'll have the head off.......you know the rest. ;)

    May not be a head gasket.
    Hope for the best.
    Prepare for the worst.

    At minimum, the head is coming off to "unstick" the valve and find the water leak, and the pan should come off to inspect the oil pickup with that much crud in the engine. With the pan off, you can use aerosol brake parts cleaner to clean up that lifter galley, and anything else you can get to, as well as the inside of the pan itself. It will take at least 3-4 cans of cleaner, but catch the runoff with the pan to keep reusing with a stiff brush.
    Good Luck! -Donny

    I think you better keep in mind that with those compression readings that engine hasn't got much life left in it anyhow. :whistle:

    Might be time to consider a full rebuild.

    Oh dont say that Howard. Cause you know with me... I will end up putting something odd under the hood to power it next. I hope to get it back to life to drive around a bit. Heck with those readings i should have a few years of service out of it :)

    Not an esy swap but one of the neatest repowers I ever saw for a flat fender Willys was in a CJ-3B one of my younger brothers dads had they put a GM 215 V8 in one also known as a Rover V8 as they used them in a BUNCH of English cars. tiny little aluminum block V8 weighing only about 318lbs making about 150-185hp at 4600rpm and around 220 ft lbs at 2400rpm You would want to drop the compression on one now to about 9-1 for fuel considerations so I would think with headers and a little work you would be looking in the 175HP area with that torque thats double a 134L

    I started out to fix a suspected fuel problem and got into a three year frame up rebuild. I hate something that is not correct - and I kept finding stuff that needed to be fixed.
