    Default b18 connecting rod bearing, is quite loose..What to do?

    The stock spec for the b18a rod bearing oil clearance is supposed to be between .0008" and .0015", and all of the bearings so far have met clearance within specifications, slightly on the loose side of things though. Until, connecting rod #3; its bearing clearance is looking closer to .002" than anything. What should i do, would it be safe to run it like that or is it an absolute must that i get an oversized bearing for that journal to bring the numbers within spec?

    UPDATE: i just re-did the plastigage on that journal, just to make sure, and this time around it came out nearly perfect. The plastic was crushed slightly flatter than .0015 but not so big that it fit in the .001.

    I personally measured all the bearings on the build and recall them being in spec.. make sure the crank doesn't get rotated or the caps get shifted when installing them or it can throw the measurements off.

    if you measured once and its off spec, and then measured again and its within spec... your doing or did something wrong, or you cant measure lol
