Pedros Techno DOF IMS fix?

[thom4782]

Data provided in the IMS class action suit indicated single row IMS bearings fail about 8% of the time whereas double row bearings fail 1% or less. Structural weakness is the best explanation for the difference in failure rates with all things being equal except the 1) the relative amount of contact surface areas of the balls and races of the two designs and 2) IIRC the thickness of the bearing support,

Even the dual row bearings, however, do fail so structural weakness cannot explain all failures. I believe compromised lubrication probably explains a lot of the rest and the 1% underlying rate. This phenomena happens when acids and particulates in engine oil causes bearing seal degradation that allows oil to mix with the bearing's grease. The combination lubricates very poorly and after some time the bearing fails.

THOM4782 based on all the info at hand,if u had an 06 thru 08 with the newer large single row bearing design that could not be removed without splitting the cases would u do the DOF mod or just leave it alone and change out the oil more frequent, especially at end of season before storage (if needed).

I just don't know enough about the large single row bearing to offer a useful recommendation myself. With its low failure rate, I wouldn't worry and, if I did worry, I probably would simply change oil frequently.

The vendors sharply differ on the question of efficacies of splash oil (the IMS Retrofit website's oiling section) and DOF (the TuneRS site and Pedro's video). I don't know whether they would hold these same opinions when opining about the large single row bearing.

My car is a single row bearing and when I get to it I plan to install the IMS Solution.
