Maybe, he said it could be the O rings too, he will check them - and could be that, although he said he has to check first, a cracked head - in case it is that, means Engine needs to come out, and then fix these right? ETA on Costs or so?
It's a known issue that Oil Coolers fail, but I asked him why would it fail since it was changed - and that could be the answer - the broken head - any tips appreciated it.
Do they sell these from here?
