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.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

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.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 2Original post

There are many things that could have happened. You certainly should not start the engine until it has been checked out by an engine specialist. This could be a very early IMS bearing failure, but it could be so early that the engine could be saved. You must prepare for the worst and that can save you A LOT of money. Smoke and noise are never good, period.

POST 3Original post

I had that happen once. I had just washed the car. Started it and drove into the garage. I did not drive it for a day or two and then when I did start it I got a white poof and tapping. After 5 min the tapping went away. I checked the oil levels and all was good. I chalked it up to a start and stop within 15ft and possible water in the intake area. Just my .02
