Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I dropped the oil pump and found quite a few brown plastic pieces. Cleaned the pan and the oil separator and found the one for Cylinder 4-6 clogged. I wonder if these caused the cylinder 4-6 head to crack? The ones in the picture are all from the pan, more came out of cylinder 4-6 oil separator.

POST 2Original post

Probably not. Many heads crack that have no other signs of any possible cause. The head just cracks from the stresses encountered over time, possibly aided by a cast mold/core shift or slight mis-position during the casting process that has the wall thickness thinner than it would be normally.

POST 3 / ORIGINAL POSTEROriginal post

You are probably correct Macster about the clog not likely the cause of the crack. In checking the Oil circuit diagram, a clogged separator would likely not cause a hot spot but more like it would allow more oil to pool in the cylinder head since the extraction pump can not move the oil out as fast...
