I applaud King for seeing a potential problem and making an effort to engineer a solution. Marketing hype or not, at least they can defend the changes they made and why they made them.

In the end I'm with Turn In I just don't want to test something new on a customer engine or even on my engine when frankly there isn't a problem there for us to fix. Oiling issues (not related to g forces found in road racing) have always been a build issue and if you maintain adequate oil pressure you don't have a problem. Time and time again I see engines with inadequate oil pressure, I warn the customer, they don't listen, and the engine spins a bearing.

If these bearings can actually improve oiling without reducing oil pressure then maybe it's a winner. If oil pressure drops due to increased oiling it will lead to more failures, not less as we have a limited selection of bolt on oil pumps.

Thanks,
Phil Grabow

I agree that there isn't an issue to 'fix' and that build quality is the leading cause of bearing failure...that and tuners not having an understanding of MBT
However, that doesn't mean that there isn't room for improvement.

If they are improving oiling, as I was stating to Jeff and actually briefly spoke with him about last night, you aren't losing oil through the radius and out the chamfer (which drops oil pressure at the rod bearing). A higher percentage of oil pumped to the mains is getting to the rods instead of simply being spewed past the shells and back to the pan. So if you can sustain necessary pressure for the cams and mains, while maintaining essentially the same oil at the rods, what do you have to lose? It might actually allow a lower pressure.

I want to see a leak decay test results or to have done now. However I have a feeling this will just leave me to do my own testing...

Isn't the company supposed to make all the testing and prove us where they made the improvement with the new design ? Instead of people being genuine pigs.

It's nice that there is a representative for the company but he is not showing us any proofs.

Did they even test them in an ej engine pushing good power ?

I really am curious to hear of what testing they did. I imagine for the claims that they're making, the would have done a decay test at least. We did this at Volvo Powertain to diagnose and analyze the oil system (flow and pressure) in the real world to study implemented changes.

As for the guinea pig bit; I'm an engineer, I always do my own testing.

^^^makes me wonder why you're asking that.

I'm curious why Gideon hasn't replied. I know he's logged on since I posted my questions...

If they whould be available for Subaru that would be nice! AFAIK only the rod bearings are available from Mahle/Vandervell at the moment and they have "normal" looking tang.

Got this from the other thread on this revised bearing http://forums.nasioc.com/forums/show....php?t=2431764

also would like to know, from what I see, it "appears" as though the new bearings came in this new package and were swapped before the customer got it. Reason I say this, is because the new style (both in same new box & same part # on label, purchased at same time) came shrink wrapped/never opened, and the old style w/out the ovaled hole came just as the bearings sitting directly in the plastic tray
btw, place items were shipped to and customer quoted above, wasn't directly purchased from you

If King could chime in on this question, Is there anyway old style bearings went in this new package? I guess from what jeff mentioned, this isn't the first instance for him

glad to hear there's nothing wrong with the old style as they are in my motor now I haven't even got back yet

I would loved to have you build the motor just didnt have the scratch for the honeybadger & had to go fairly basic, Thanks for the phone call back answering all the questions, def a good guy to deal with here

No we will not ship the older style EJ Subaru bearings in the new packaging.

King tested the new design main bearings in a high horsepower engine and the result was at least 10 lbs of oil pressure increase. The new design stopped the leakage of oil at the main and forced more oil thru the crankshaft to the rods. The oil slots allow a better distribution of oil into the main bearing clearance space.

Did you have oil pressure? Did you check clearances? Use assembly lube? You said the stock ones lasted 234000 so I'm assuming you had a bearing failure then rebuild it did you hot tank everything and replace the oil pump and oil cooler to get out all the metal shavings?

the rebuild was due to a piston ring land being crushed , i wont even respond to the guy that just has to flame people.
cowboy ...yes i did every thing you said ,plus had the motor rebalanced when i put fordged pistons in head studs,plasti gauged it ,heads were done ,and crank was polished .i think i got a crapy oil pump is all i can figure .i'll have a pressure gauge on it next time . but i never had a oil light come on .been building engines since i was 15 years old .high school and college auto tech classes and GM school built a lot of motors ...never had one do this .Thanks for the tips

Plastigauge works fine. Plenty of people use it all the time. I used it on my build and went 43k before I cracked a cylinder after changing turbos

King, why haven't you mentioned that you worked with http://vtcar.com/ on these bearings. The company that builds all the cars these kiddies look up to haha.

All these pages and still no pictures? I have been using these bearings since the release and have yet to have an issue in the 10+ motors I used them in.



Here you can see the 360 groove, the smooth ID side where the tang indent would usually be, and the slotted oiling holes.

I would of kept using the NON-G bearings over the ACL anyways. King always has better tolerances for me, and the differences bearing to bearing are all within .0002"

I don't need to make a reason for people to buy them, the less people that believe in change is good, the more bearings for me. No dreaded backorder issues... ughhhh...

What sort of clearances has everyone been using with these? I notice there is no extra clearance option. My mains are stock tight. I'm okay with that but it would be nice to hear that someone else has done that also.

Ok guys - I'm willing to give the new bearings a shot on my personal motor that will be going together soon.

Problem is the King website is a nightmare to get to the catalog to figure out even the part numbers.

Can someone help me out?

^^^ beat me by THAT much! I'm also putting these in my current build.

MB5382XPG are the mains in standard size, #5 thrust.

CR4125XPG are the rods in standard size, 52mm

Both are available in STDX for .001 extra clearance.
