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.

I’m only replacing the bank 1 tensioner which is positioned under the engine so yes, can be replaced with the engine in situ.

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.

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

POST 1Original post

Hi all, I'm finally getting close to getting my 06 Boxster S ready for inspection and registration. Took it for a sneaky drive around the back streets here tonight to get the engine up to temperature and plug in the iCarsoft Por2.0 and see what the car tells me. Whilst I took it pretty easy the car seemed to run pretty smooth but I did have a "check engine" light appear. Here is a link to a short video of the display from the Por2.0 showing bank 1 camshaft variation Any suggestions or ideas? Thanks, Julian

POST 2Original post

High enough Cam deviation readings could indicate chain stretch, deterioration of the chain guide rails and/or chain tensioner issues.

POST 3Original post

So after a bit of research and a couple of brave pills I decided to take off the sump and see what was sitting in the bottom of my sump. I was really hoping to not find bits of metal because that would be bad. None found. I was also hoping to not find a bunch of bits of plastic chain guide because that would mean I'd have to take out the engine etc etc.... None found, well actually 3 tiny tiny pieces. I'm now working on the theory that my bank 1-3 tensioner is/has failed so I'll be ordering one tomorrow (Marin Porsche had them for $96). I'm not sure if I can just take it out and poke in the new one though. I saw somewhere that it was thought toy need to lock the cams. That doesn't really make much sense to me but I'm not a mechanic. Has anyone else done this? Anything I should be aware of?

POST 4Original post

Can those tensioners be replaced with engine in the car?

POST 5Original post

I’m only replacing the bank 1 tensioner which is positioned under the engine so yes, can be replaced with the engine in situ. I have just picked up the new tensioner at lunchtime so will be installing this weekend and contrary to my previous post I will be locking the cam/engine at bank 1 TDC. Fingers crossed I’ve got this diagnosis right and everything is all good after this…. Stay tuned.
