Ok so after a very long time and a lot of head pounding against a wall. I think I might have figured out what the problem with the Jeep is. I think I have a burnt valve. So I have started to tear down the head.
So anyways I am most of the way through the tear down. I am stuck at taken the head off. I'm trying to figure out if the head bolts are a 12 point 15mm or a 12 point 9/16.
Dose anyone know??

 

What feels tighter?

 

1/2 Twelve Point Deepwall ,I was told 13mm by several,that is incorrect. Sears sells them individually for around 10.00 in 1/2" or 3/8" drive. Most Auto parts dont have the 12 pt. Deepwall in Single or Sets

 

^^^^^^^

Exactly what he said...
