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

Suggestion
Apparently you are replacing the chain rails which requires pulling off the oil pump housing, so you removed that already.

But replacing corresponding long chains (from IMS to cams) requires splitting the cases, unless you split the chain itself.

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

Hello all, I was doing my timing chains and guides on my 2002 3.2L Boxster. Everything seemed to be going well till I went to install the oil pump/water manifold and my ims is not sitting centered in the bore. I was going to see if any one has seen this before? Is this a symptom of ims separation? I was going to tap it with a brass drift and hammer to se if it would straitened out. I will up load a picture shortly. My photo isn’t in the right format.

POST 2Original post

Did you lock the engine at TDC and employ cam holding tools before starting work on the chains and guides? If not, the engine has jumped time due to the pressure exerted on the cams by the valve springs, causing the IMS shaft to move upwards and usually to the right.

POST 3 / ORIGINAL POSTEROriginal post

Hello, I did have the crank lock tool in but not the cam lock tool. I still have the plugs out and can see that the cams have not moved on either bank. I was trying to post pictures up but it appears they need to be hosted, which I don’t have the ability to do anymore.

POST 4Original post

Do you have ALL the hydraulic tensioners out of the engine? The cams also do not have to move very much for this to happen....and "eyeballing" the cam positions questionable at best, they should have been locked down before you started.

POST 5Original post

A little more elaboration on what you did would help. If you save your picture in jpg format you can upload it. You are saying you are doing chains. Which ones? Apparently you are replacing the chain rails which requires pulling off the oil pump housing, so you removed that already. But replacing corresponding long chains (from IMS to cams) requires splitting the cases, unless you split the chain itself. But then it doesn't matter what is happening at the heads because they should come off. So I'm confused.

POST 6 / ORIGINAL POSTEROriginal post

I loosened the cam sprocket fasteners for bank 2, after reinstalling the locking tool, and it pretty much fell back in to place. Thank you for the help guys.
