muy f22b1 vtec engine has 22222 stamp on crank and ccbcc stamped on block which comes out to y/g,y/g,y,y/g,y/g. (that's yellow and green.)
with yellows in the block and greens as well..(I know it meant one half yellow one half green, but I wanted to see the difference in the bearings...)the yellow had a clearance of .0020, which is the service limit for journals 1,2,3 & 4...
here are muy books' readings
-oil clearances-
# 1 &4 standard .0005-.0015 service-.002
# 2 standard .0008-.0018 service-.002
# 3 standard .0010-.0019 service-.0022
# 5 standard .0004-.0013 service-.0016
I also tested browns and acl bearings.
these are the clearances I got with a dial bore gauge.....
green bearings- .0019
yellow bearings- .0020
brown bearings- .0015
acl bearings- .0025

any help would be great

 

what should I go with? the stamps on the the crank and block are keep the clearances in spec with different bearings..

 

Sounds like you are rebuilding the motor, you want to go with spec's. The markings are just where the "engine started". So if you have pulled the crank and no machine work done and are just going for new bearings....get them to spec's. Try the next "thicker/smaller" bearings. So, it looked like brown was there.....close on #5, edge of 1 & 4.

 

yep going for a rebuild here... just a little confused cause of the stamps on crank and block... the bearings that were in there was working. never had oil pressure trouble or anything but when you read the specs they kinda make me worried cause the yellow/greens was working but are out of spec
