Spent a few days last week replacing the head gasket on the 6by. Was heading down to the Mods gathering in sth Qld but didn't quite make it. Got down near Rocky way and had a low water alarm. Pulled up to check and found water ****ing out of the overflow tank. Thought I must have had a malfunctioning thermostat so I pulled the guts out of it and fired her up again. About 20k's down the road it comes on again so I guessed it was the head gasket and turned around. By taking the cap off the expansion tank I managed to get home with only 1 stop to refill the radiator. Then tossed some of my camping gear in the Falcon ute and headed off again. When I pulled the head this is what I found. Had been leaking under compression between cyl's 2 and 3. The head was slightly warped up in the center so i had to get it shaved. Some of the head bolts in the center were noticeably looser than the others so I think this problem may have been caused by human error on the assembly line. With the low k's mine has done I am sure it hasn't been tampered with before. All good now - just did a 650k round trip and goes like a ripper!!!Attachment 125252Attachment 125253Attachment 125254
