I am rebuilding a 4-134 f I cant find an exhaust valve that matches the one I have. The shaft is 12/32 in diameter the outside diameter of the valve is 13/32 the inside diameter of the valve seat is 8/32 The length of the valve is @ 5.75 in The valve clip holder at top of valve is 7/32 deep. Then this has a .25 in hold space/ then has a .5 inch taper to the shaft width do you have a replacement valve like this? It is stamped Eaton 28EX

Willys Jeep Parts Tech:
If you have the valve that accommodates a tapered shaft where the retainer is that is available used only.

I am rebuilding a 4 134f my existing valves( exhaust)valves have a rotator cap.i bought new exhaust valves thay are longer and looks like thay will need a different spring retainer and locks then my old ones are thay going to work

Willys Tech:
Sounds like you have a military 4-134F engine. Please call us toll free.

I am rebuilding a 4-134F in my 53 M38A1. Are these the correct valves for my application?

Willys Tech:
800829 is the exhaust valve for the military. Please call us toll free. We have limited supply. These are the proper one for all civilian motors.

I am rebuilding an F head military motor. If I use NOS vaulves, do you think I will have issues with the current unleaded fuels.

Willys Tech:
If they are stainless then you are ok. The ones we sell are for the unleaded fuel.

I have a 1963 willys jeep, I have the valves out of the engine. Are these the correct ones?

Willys Tech:
These are the correct exaust valves for all civilian 4-134 F head engines. The military ones were different but we can help on those too.
