ims bearing panic

If the IMS to crank chain wore thru the wear pad of the aluminum tensioning paddle shown on the right side in this pic of a 2000 Box engine crank housing, it will make shavings like that until it breaks in half. If you remove the chain tensioner right beside the oil filter you can get a peak at the paddle & Maybe see if it is damaged. The chain & wear pad are on the backside, so it could be excessively worn, & you can't see it thru the hole. When you remove the oil sump plate you will probably see more shavings there.

This is what I was referring to.

You can fit a boroscope through the hole and inspect it as well. We did this once --
found one of the chains (of two) had broken. We saved the engine - but it still had to be torn down and put back together with a new paddle and chain assembly.
The chain broke because it was wearing a groove in the paddle.

That's a lot of shavings -- and my gut says that you would be down to some material
in the bearings that was ferrous (isn't there copper in most bearings -- I know there is on the 944)

There was a slight tick in the area of cylinders 4 and 5 that I thought might just be injectors. It was faint.

Pull the sump plate and post pics. I have seen this one before.

Email me the pics to jake@flat6innovations.com.com as well since I am seldom on these forums these days.

Will do Jake, and I appreciate you willingness to have a look at it.

Sump screen.
Obviously someone has been in here poking around before me. they used silicone for a gasket, and quite a lot of it. I was very suprised not to see the material from the filter litter thruout.
