So I adjusted the timing as instructed, and after doing so I am on the edge of the slots with no more room for adjustment, this seems to me to be not an optimal place, but it is working.

2) I don't believe it is a bad vario cam, I base this on I pulled the cam cover and inspected the tensioner.

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 1 / ORIGINAL POSTEROriginal post

So I am hoping someone here can help with my question. I have an 2001 boxster S that is having an issue with Timing. I found the DIY on setting timing here. My timing in bank 1 looks like the photo where the timing is off and the slot is NOT vertical. So I adjusted the timing as instructed, and after doing so I am on the edge of the slots with no more room for adjustment, this seems to me to be not an optimal place, but it is working. So My question, What would cause 1 side of the engine to be out of time and not to the point of triggering the CEL? Is this something that normally happens? Should I be worried of a bigger issue? Here are the things to rule out for sure. 1) No it is NOT the IMS, this was my first thought so I pulled the tranny and clutch, bearing is still perfect, but I went ahead and replaced it with the LN bearing. 2) I don't believe it is a bad vario cam, I base this on I pulled the cam cover and inspected the tensioner. The chain guides look new, I don't see any wear on them to indicate a failure there. 3) I pulled the sump, there was nothing in the sump to indicate chain wear.

POST 2Original post

Okay some stuff I don't know: Has your engine ever been apart? Not sure how you're able to see all the chain guides to verify they look new. 5 chains, two plastic guides per chain. You might get a look at the ones between the cam shafts but you'd have to be an ant to see much of the others. First guess? Pressed on sprocket on the IMS has been known to slip a bit (or a lot). I pinned mine with a set screw using a procedure I found on line

POST 3 / ORIGINAL POSTEROriginal post

Im not sure on if engine has been apart. The car is fairly new to me. So i dont have entire history. You are correct on chain guides. I can only see the ones on the cam shaft. I was expecting they could be worn since only 1 of the 2 banks was off time. But the vario cam unit and guides look really good. So the sprocket is a press fit, and if someone was to downshift hard and over rev that could spin in the shaft. Thanks
