The oil cooler seals are probably worth doing just for the piece of mind if nothing else. For the record, the turbo does NOT have a heat exchanger (oil cooler) in the oil filter housing like the N/A's. In it's place there is a short tube that has two o-rings on it that need to be changed to prevent the oil/water mikshake, and potential rod bearing + damage. The turbos have external oil coolers. The kit will have several parts you do not need. For the turbo, you will need the following:

1 ea. gasket 944.107.147.03 for housing
2 ea. o-rings 999.707.043.40 for connecting tube
1 ea. connecting tube 951.107.152.03 (replace if damaged)
2 ea. seal rings 900.123.011.30 for oil line adaptors (these leak if disturbed at all!)

1 ea seal N 043.815.03 for OPRV
1 ea o-ring 944.107.935.01 for OPRV
9262/1 alignment tool for late model blocks

This may not be the list you are referring to, but here it is my list anyway.

1 each Guard rail (for updated pump) 944.105.210.01
2 each Lock nuts (for guard rail) 999.084.092.02


Notes:

1. Spacers and oil pump sleeve should be replaced if they have wear grooves, or burrs which could damage a new seal. Use some fine
grade scotch brite to clean up the old ones, but replace them if in doubt.
2. The front crank seal is prone to leaking if not installed perfectly. I use an old crank gear and oil pump sleeve that I honed the center bore of to make it easy to slide on and off the crank, and use these two as spacers with the crank bolt to press the seal in squarely until flush with the oil pump face.
3. The balance shaft front housings must be removed to properly reseal them.
4. Oil seals and o–rings must be thoroughly lubricated before installation.

Have fun!

When does surgery start on yours? I have a suggestion for you. Rent a tow dolly, remove the front bumper cover, drag the car to my garage (heated!) on a Saturday morning, we can take it out and put the front end back in it and you can drag it home that evening and put it in your garage. We might even have time to start dissecting the engine and see what all is broken.
