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

hi all is it necessary to remove all 3 chain tensioners before removing the oil pump (main pump) or is it enough just to remove the bank 2 tensioner?

POST 2Original post

Why do you think you need to change your oil pump??

POST 3 / ORIGINAL POSTEROriginal post

The pump is rattling at idle when warm. I have the cover of and can see is is starting to wear out. thats why I will change it.

POST 4Original post

Quotes source post: 15180553

That seems quite unusual, can you post pics? as far as I know the pump is very reliable, unless it ingests garbage and gets damaged

POST 5Original post

Could the rattling really be the IMSB? The pump is driven off the shaft.

POST 6 / ORIGINAL POSTEROriginal post

It was enough just to remove bank 2 chain tensioner. I locked the crankshaft just in case.

POST 7Original post

So, was the pump damaged? I had mine out this winter, they are pretty robust. I think I'd be checking filter and dropping sump. If you find anything there, pull the transmission and check that IMS.

POST 8Original post

I too would like to see what a damaged oil pump looks like. Have you dropped the sump and inspected your oil filter? As others have said IMSB would be my main concern!

POST 9 / ORIGINAL POSTEROriginal post

Nothing observed in oil filter and the pump had only minor surface scratches on end plate and opposite side of the two pump gears.

POST 11Original post

Then the rattling must be something else. Are you sure it's coming from the pump, maybe a pulley bearing? Lets us know what you find.

POST 12 / ORIGINAL POSTEROriginal post

Yes it was from the pump. It is now rattle free after replacement. I had also expected more wear inside to make it rattle like it did.
