DOF IMS Bearing - remove 1 seal/pierce the other?

LN Engineering developed their own bearing system, experimenting with different materials both for the balls and the cages before settling on the design marketed. The resulting product is made exclusively for them, and is not available "off the shelf", regardless of what many seem to think.

And their design works, with over 10,000 installations there have only been a handful of failures, most related to poor installation techniques, retrofitting an engine already full of metal grit from an existing IMS failure, or contamination of the bearing by metal from an unrelated engine component failure.

with over 10,000 installations

Soon that number will be doubled, its already near 18,000 for all the various LN/ IMS Solution offerings. There were 350 installs last month alone.

DOF IMS bearing is in. Outside oil seal removed as suggested by Pedro.

The instructions call for: "Working from the top of the engine, remove the factory oil port plug on the left side of the top of the engine, next to the air filter box and
under the rear end of the fuel injector bar (on the Boxster)."

The oil port refused to come loose. Eventually I resorted to extraordinary means. I don't imagine anyone envisions this approach to remove a little plug.

A less violent alternative might have been this?
NEW Development – DOF Oil Feed Plate
And it has other benefits too.

I like the concept. You get the advantages of the Bilt Racing Oil Cooler Delete. For installing external oil cooler. Eliminates heat exchanger. M96/M97 only. - Parts & Upgrades - Products LN Engineering while supporting the DOF.

Maybe another time. I am anxious to check out the transmission that we rebuilt by ourselves.

And draw backs. On the Boxster M96, use of this plate requires the use of the smaller base engine oil cooler in order to fit under the intake manifold; so you give up oil cooling capacity and the oil runs hotter. In no way is that an advantage.

Yikes! We want cooler oil, not hotter. I guess I thought that a remote oil cooler could be larger.

If you configured the car to run a remote oil cooler, it might, but most people (and correctly so) want to run the large "S" oil to water OEM cooler as it effectively cools the oil in the summer and warms it on cold starts in the winter, and it simply will not fit under the Boxster intake with that plate underneath it. And I have no idea where you would mount a remote oil cooler of any appreciable size on a street driven Boxster so that it could get ample air flow over it; there is little room at the rear of the car, and the front is too far away for the OEM oil pump to handle the load., which is why Porsche went with an oil to water cooler in the first place.
