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?

Well I finally got the head off.

It took two pry bars, several drift pins and lots of wood wedges. Oh and a
2lb ball peen hammer and a block of oak to beat on.

The thermostat bolts do not go thru the head. thank god.

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.

Head had two head gaskets so head and block will need to be machined for
sure.

I didn't see anyone mention whether or not the bolts go through to the
block. 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. So I'm fixing to pull off the head as
time permits.

PS. I third the motion about the easy out. Too easy to break off-
hardened steel can require electrode burning to remove. 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.

Gary,



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

Hello Hal,
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.
