Hello i built a forced induction b18c1 motor for my integra, the motor is already in my car and i found out i got the rod bearing clearences a little too tight. Is there any additive i can put to help wear the bearings or anything i can do to fit this. I just dont have the time to pull the motor and redo this. thanks

 

Nope, you have to pull it and swap out the bearings. No getting around tight clearances.

The surface of the crank journals and the faces of the bearings never actually touch, they're separated my a film of oil.....so they don't wear in at all. What were your clearances and how did you measure them?

 

How do you know you have them to tight?????? And when did you find out?

 

didn't you measure the clearances before you put everything together?

 

you dont have to pull it out. i have rolled rod bearings in my gsr twice and its easy.

 

What are the bearing clearances?
