🔧 Replacing The Head Gasket On A Willys L134 Flathead Engine

[@stevewaterhouse3025]

Hi there Scot, Thanks for this great site ! I have a 1943 GPW, it's been lovingly restored by a dear friend who was meticulous with every detail. So generally I have only had to replace the coil in the year that I have owned it this little gem. I'm sure at some point it will need a repair of some sort and Team G503 will always be the place to go for top advice !! Thanks again!

Good job guys! Hearing that run put a smile on my face.

Curtis Harrenstein as to mine my friend, I was really worried with all the steam coming out after we did the job😉👍

[@stevewaterhouse3025]

loved the crack of the cold one at the end of your vid. I have a 43 GPW and it is a source of joy for me. Keep Jeepin brother!

Awesome job guys 🤙

I heard that "Fresca soda" bottle cap jumping off the bottle. Hope that opener was "drab green" in color!

[@TeamG503]

al bugnfront you caught that huh😉 Janton recently received a lot of attention for his installation of a coke bottle opener on the back side of his Jeep on the G503 Facebook Page😉👍

Need a little carburetor adjustment or new points n a condenser sound like???

Hi! Great job you guys! I have a question. I just got a 1951 CJ3A. It was sitting for 20 years. I started to remove parts that I'm going to replace on the engine. I accidently removed the entire stud which the oil filter is held down by and I noticed antifreeze bobbing around in the stud hole. I have not removed any fluids yet but I don't know if that is normal or if I have a bigger problem. Do you guys know?

[@peterrath9097]

Nice, I have the same problem! What thread locker did you use?

[@leftcoast9261]

If the threaded bolts were corse threaded into the block. (A good possibility) Then they should be torqued at a higher value. Been there, blew the head gasket for my education. How much higher? For the Jeep, I don't know. My engine (Dodge) came with either, so I was able to look up the difference.

[@Cycle9568]

Should you pull the studs out of the block every time you do a head gasket? Thanks. Sounds like you have some valves out of adjustment.

[@baioszisimos3367]

I have a m38 that also have issues with head gasket. Lots of White smoke .i m thinking replacing the head gasket. Did you also do cylinder head flatness?

[@TeamG503]

baios zisimos on this one we did not. You can check the block side with a straight edge and or visual inspection. The copper spray helps seal the small imperfections. To machine the top of the block, I believe would require removing and disassembling the block.

[@jonjon9047]

That head should drop nicely once it’s square on. Clearly they have a bent stud or two.

[@TeamG503]

Jon Jon studs are all brand new, quality. There are many helicoils in the top of the block. I personally have never had a head just drop on. It worked out well👍

[@Frankensteins_Highboy]

Also have never had a head drop on easy Always hangs up on something weird

[@shall2117]

What carb do you recommend? I also have a Solex

[@mudgrippmike3489]

hmmmm my 1951 CJ3A HAS bolts for the head, not studs and nuts.... Would the torques be the same?? 9/30//24

[@badrussian4999]

Fuel filler neck is not under the driver's seat. Tell me please, what year is this Willys?

[@TeamG503]

BadRussian Jantons Jeep is a 46 CJ2A that has been militarized. That is why the filler is on the outside of the tub. 👍

[@badrussian4999]

@@TeamG503 Many thanks!

[@453421abcdefg12345]

I think you will find that was steam, not smoke! Just don't leave your fingers under the head when you drive it down, it is even harder to get the head back up than pushing it down, especially when your fingers are under it!

[@devonguthrie2234]

What copper spray did you guys use on the head gasket?

[@thomashynd2291]

I hate it when the head initially doesn't want to go down and then when you least expect it, it drops. The tips of your fingers don't like it!!!

[@TeamG503]

That is a great tip. That would be keep those finger tips. 👍

Kopparsraj är inte bra att sätta på en topplockspackning! Det göra att den glider lättare å brister, 😢 det ska inte vara olja,fett, eller annat glidmedel mellan ett bultförband, å speciellt inte på en topplockspackning.
