Are these for F head 134 engine? Stupid question, but where do they go? I have a 1967 cj5 and a novice on this engine. Would you have a detailed drawing of that motor. much appreciated.

Willys Jeep Parts Tech:
Yes that is right. https://www.kaiserwillys.com/diagram/cj-5-6-diagrams This link will help alot.

do you have the plug for back of engine foe cam journal

Willys Jeep Parts Tech:
51460 is the part number.

Are your expansion plugs a dish or a shallow cup ?

Willys Jeep Parts Tech:
See 2nd image. They are shallow cup and made proper.

Is it normal for these not to hammer in all the way so that they are flush? You can physically see by looking at the free plugs that they are thicker than the hole in the block will allow for. The hole in the block has a bevel at about 1/8 inch and these are 1/4 thick.

Willys Jeep Parts Tech:
They should be tapped in for sure and be tight. But I wouldn't say hammered in.

Hi, will this plug fit on the 6Cyl Super Huracane engine? Regards

Willys Jeep Parts Tech:
No, I'm sorry but this plug is only for the 4 cylinder. You should be able to match that up locally. Thanks

How deep are these? The ones I pulled out were only slightly thicker than a coin, these look pretty deep in comparison.

Willys Tech:
There are different styles used. They are approx. 1/4 thick.

Does the lip/flange go into the body of the engine?

Willys Tech:
Yes that is correct.

How many freeze plugs are in a standard F134 engine?

Willys Tech:
I beleive there are 4.
