Hi Hal good to hear it came off so easy,only kidding .you comment about the use of two head gaskets leading to a problem or damage may not be true.this was a some what common way to deal with poor quality fuel back in the day by lowering the compression ratio a small amount. In some old motors manuals this was often refered to as preparing a car for export use like Mexico or south America where the quality of gas was very poor.I'd check it carefully but it's probably ok if compression was good to begin with or was lower compression the reason for pulling the head?

Problem appears to be lots of grease and crud and super tight tolerances on the studs. maybe one or two bent slightly. Good news is the cylinder walls are clean of any surface rust from what I can see. So now I pull the engine and start teardown of the lower half to see how that looks.

If you do get the head off, can you post what was holding the front on? I too have a stuck L6 (229) in my 1962 PU. I also can not get it to turn with a socket and pipe.

Hopefully the head is not held on and you can get a vicegrip on the remining shank of the bolt when the head is removed. |

Reason to pull the head was to see what the cylinders looked like, the last time this vehicle was titled was 1993, registered 1999 and it has sit since then. Plugs came out in my hands without use of a wrench. Was afraid the cylinder walls were solid rust. I was unable to turn the motor over with a socket so was I needed to see if it was worth saving or look for another motor. So far I will proceed to pull the motor and do a tear down. First motor rebuild for me so being cautious. Now to find parts for a 161, so far very hard to find. at least so far. Hal _____ From: WillysTech@...

You may not need much to get it rolling again, this sounds much better than my 161 that is still running off of used parts from the willys factory :). I would have everything measured, and if it is within specs, re-assemble with new rings, bearings and gaskets. Many machine shops like to get your money and will machine it all even if it is in decent condition. Parts are hard to find, try kaiserwillys.com, eggie (SP?) and kanter.
