I'm building a B16 that I had golden eagle bore to 86mm. I went to put the block together this morning and after plastigauging my crank i'm sitting at a .002 inch clearance across the board. This is with new OEM bearings. On journals 1, 2, and 3 I have green bearings, on 4, I have yellow bearings, and on 5 I have brown bearings. I know that clearance should be between .0009 and .0017 inch so I was going to order new bearings but a few of my honda friends are saying that I should be fine at .002. What are some of your alls thoughts? What color bearings should I go to if I do need to buy new bearings? Thanks!

 

hi paul everthing will be fine

 

.002 is the service limit for honda bearings, some people like to run them looser because the motor creates a little less bearing friction and spins up a bit faster. its looser than i run all mine but you should be ok. i tend to run my bearings around .0017 to .0015

I ran my bearings at .003" on some journals. Dunno if it'll be a problem yet, hehe.
.002" is mint a riffic, you'll be good to go. I made mine looser cause I'd like to make a little bit more power, but if you want the bearings to have greater long term (like more than 200,000 miles, cause I've seen bearings at almost 300,000 kms that looked good to go.) then go with a bit tigheter.

 

Thanks Nick...just wanted other opinions too
