Malek has a pretty good reputation. I think he is able to correctly torque the bolts. I have no issue trusting what he reports.

2008 here with replaced bearings and were replaced with the newer OEM bearings. I plan to eventually do BE/VAC and will share pics of my OEM bearings. That is the first time I know of that someone has shown OEM bearings being replaced twice.

I don't want to slander Malek, but the info is out there on the testing of the bolts he was using, and at the recommended torque spec the big end bores of the rods show considerable distortion. I'm sure he has updated his torque specs/bolts since this info has come to light.

The worst part about all of this is.... EACH ENGINE IS DIFFERENT AND WILL SHOW DIFFERENT WEAR PATTERNS AND BEHAVIOR. You can't look at one engine's results and say " well mine must look the same". We have seen too many examples of the original bearings showing drastically varying levels of wear at similar mileage. Changing the bearings in 100 engines won't make every single one of them magically wear the same on the new bearings.

http://wiki.rcollins.org/core/index....2000_rod_bolts The bore distortion and extra clearance says to me, that pictures of the bearing shells after removal aren't of any scientific value to tell how well the bearings themselves did their job. |

It’s a thread specifically asking for those who have swapped their original bearings for BE bearings to chime in with progress reports after they have covered lots of miles. That way we can see if the extra clearance of BE bearings is a potential long-term solution. Hopefully this thread will become a resource in the longer term for those who are thinking of changing their bearings and wondering which replacements to go with. But thanks for your helpful comment anyway. |

But you're right . Instead of reading through the useful info that's been posted just LAST week about BE bearing and how the experience with them has been great , and how nobody except MRF or maybe deansbimmer has pulled them back out, where they also provided pics if I recall . Let's go fire up some 2-5 year threads and ask the same question again. |

Just a heads up for those who care. I have the non extra clearance VAC bearings. As the extra clearance bearings were released not long after I replaced mine in 2015, I considered if I had made a mistake using VAC bearings. To my surprise, 3.5 years and 20k miles later plus a super charger, my car runs great. No strange wear in the oil reports which have been done every time since the bearing change. Checked the filter every oil change for flakes from the coated bearings, nada. As others have stated, the wear that causes the bearing problem may occur early on then stop. As long as you replace them with something, you probably dont risk catastrophic engine failure from the rod bearings.

Hydrodynamic bearings should not need to be considered a wear item in a passenger car, even a really high performance car, when properly designed (read clearance is correct). How many Porsche, Corvette, Acura, Honda, Kawasaki, Yamaha, Ferrari, Bugatti etc. engines consider rod bearings as wear items? Cheers,

Math is math. Physics is harsh mistress. Blown S65s are costly. Simple truths. But alas, it is what it is.
