Great videos but those hairline cracks are harmless the piston crowns are very meaty on the patrols. Typical after an overheat to see hairline cracks on one piston, a bad overheat they could all crack. I cant see the crack so if its bigger than a tiny hairline crack then it must be changed because he will get some more blowby 😊 I rebuild a lot of these engines here in Ireland, mighty reliable engine if looked after and not overheated.

i’m about to replace the head in mine, are u saying if i come across a hairline crack like this it will be ok to run it like that?
Love your content. Great videos and a true workshop👍
Thanks mate
Could a cracked head prevent the engine from starting due to no compression? If it's cracked in a few places?
Thats a tough one mate , How do you know the head is cracked ???, you need to do a wet and dry compression test.
Could all the Crap mounted in front the radiator aided in this engine over heating?
No
How much did this repair cost?
i don't remmember
I have to pull the head on my GU Patrol soon as I suspect a cracked head, just hoping I don't find same problem with any of the pistons..
Hey mate how did you go? Did you only have a crack head as well as piston. I'm about to take head off mine aswell not sure what to expect.
