I had this posted in tech/misc forum but I am not getting much response.

I just plastigauged my Gsr block with the new main bearings, everything came out to be .008-.011. I have read in an archived post of suggestions of using the acl race bearing kit when this happens, but can I use these Oem new bearings?
When I bought the oem bearings I went by honda's color chart from my helms manual. the honda color chart gave me 3 blue, 1 black , and 1 brown. All of which are thick, but that is what everything equalled. Now they are all measuring between .008 - .011.

so people will have a visual here is an archived post of the same problem. these are almost exactly how mine measured out. the number 2 journal which looks to be tighter than .010 is how most of mine looked.

Should I try to clean everything better, and measure again? Or order thinner bearings? Or put it together and let it ride? any help is appreciated

 

are you sure you are using the right plastigauge, should be green on the outside

 

it is green. I was not aware that the bolt threads should be cleaned, etc, i just cleaned the actual surfaces it was touching, but i am going to have to clean everything and re-measure, but i was wondering if anyone has ran tight bearings like this?

 

anyone have any suggestions?

 

the middle bearing on the mains should have the most clearance.. depending on what you want to do with your motor will dictate how much clearance you will want..

 

it is a gsr block, with jdm itr rods/pistons, all new oem bearings.

then I have a b16 head with crower cams, supertech valves, springs, retainers, etc.

it will be tuned as soon as I break it in.

this bearing issue is the only thing holding me up, i don't know if i should remeasure, or buy acl bearings, or what.
