    Need Advice | WPC treatment of Rod Bearings

    Guys!

    I am thinking of getting WPC treated rod bearings for my car.

    http://www.wpctreatment.com/about.htm

    Appreciate all advice and suggestions.

    Thanks
    Hasan

    Any updates on this? Seems like a good solution to the rod bearing issues on the S54 S65 S62 and S85.

    In the meantime I've been using Liqui Moly's CERATEC. Works on all friction surfaces and the motors treated seemingly run ever so slightly quieter.
    Life is a journey. Enjoy the ride. Enjoy it in a BMW.

      I got the WPC treated bearings and ARP rod bolts and replaced them. Below is my thread.

      If the engine is running quieter, it means the oil viscosity is higher and it is not good for your bearings.

        Thanks for the response. I've also switched to a thinner oil Liqui Moly 0w40 (also purple bottle full synth) and no longer the 10w60 TWS.

          That's a good choice of oil.

            2 train of thoughts of WPC treatment of OEM bearings.. One is that it reduced the space for the oil to run through, the other is that the bearing itself is tougher.. Beats the hell out of me, both seem correct to me.

              WPC is like a pinning process, it should increase the clearance of the bearings and oil should flow better. In addition, the uneven surface created should retain oil for better protection at start up.

                My guess would be that an uprated oil pump would be much more beneficial. ;-)

                  That is very interesting. How will an uprated oil pump help?

                    More px, more volume of oil going through the bearings under higher px. So much less likely that the join will be dry. If there was no contact between the bearing, there would be no wear, the higher px keeps the bearings apart. On a nano level of course.

                      Oil does not compress, so the additional pressure will not result in additional flow.

                      The problem is the clearance on the bearings. So you can either improve the clearance or use a thinner Oil.

                      More pressure on the same viscosity oil will not do anything. Pressure and and flow have inverse relationship.

                        Thats true, however using a thinner oil, you will want more flow, so how do you get more flow?

                        Oil can actually do work, so it must be able to compress. :) actually all liquids can be slightly compressed.

                        For what its worth, I also went with WPC bearings..
