<VV> Rod Bearing Clearance Question

[Bob Gilbert]

Hi,

 

I've just started my 190 ci (3.l) build for my UltraVan and I'm using Bob
Helt's book plus the shop manual as my primary guides. Its' been 20 years
since I have done a complete engine like this so I'm using the books a lot!

 

The crankshaft was checked by both myself and a machinist we both found all
of the journals to be in spec and he recommended that all it needed was a
micro-polish.

 

I plastigauged the mains and the clearances were between the .0015 as per
Bob's book and .020. That was with standard size bearings.

 

However, I'm showing .002 clearance on the rod bearings. Bob says that .001
is ideal but I can't find anything to say whether .002 is enough to cause me
concern.

 

BTW, these measurements are being taken at about 40F. Is that enough to
cause the journals to shrink by .001?

 

Any thoughts or recommendations?

 

Regards,

Bob
