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

[Jake Raby]

Waste oil does not exit at part 24. The IMS tube is fitted with a plug that is designed to keep the oil exiting between part 27 and the male end of the flange. Part 27 includes a design integration that promotes oil shedding at this point, during operation. This doubles to act as a safety for cold starts before oil pressure is achieved.

The IMS Solution was the very first IMS Retrofit technology that we invented. It has more developmental and practical application time than any other product we've released to date.

All other specifications being equal, ceramic is likely "better".

Steel bearings are inexpensive and available from the high quality brands NSK and SKF. (about $15 for a single row and $50 for a double row)

Hybrid ceramic bearings apparently have an excellent reputation; you will need to do some research if you want to avoid Chinese bearings. Costs seem about triple that of steel.

IMHO...

The IMS Solution is best retrofit for single row cars because plain bearings do not fail catastrophically as ceramic and steel ball bearings do when they collapse.

The Gen 2 Single Row Pro IMS Retrofit is the next best option for single row cars because its design allows it to carry loads almost as high as dual row bearings

Ceramic ball bearings are the third best replacement for single row cars and the best option for dual row cars because ceramic balls last longer than steel ones on tough operating environments.

Depends upon whose bearing it is. The right ceramic bearing should run rings around a steel counterpart; that said, not all ceramic bearings are the same, as some have discovered to their detriment. 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.

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.
