Last Sunday I got around to checking the main bearing clearances and got some good results. All 5 of my main bearings were in the .0013-.0015″ range which is within the limits of what it’s suppose to be. I had some time today so I posted how it all went.
I wiped off the area where the bearings sit in the block and placed the new bearings in place. I then used the Green Clevite’s Plastigage to check the clearances
I cut a small piece of the plastigage and placed it across all the journals
I then put the other half of the bearings on the main caps. As you can see in the picture on the right the plastigage is barely visible.
Two of the main cap bolts in the D16Z6 are longer then the others so I made sure I inserted them in the 2 middle holes on the main caps. I remembered to lubricate the bolts and the washers in oil for better torque feel.
Working from the middle I started finger tightening all the bolts first, then to 18 Ft-lbs then to 38 Ft-lbs. Once they were all tight I loosened all the bolts in the same pattern and took off the main caps.
Then I checked the journals using the plastigage and mine were reading .0013″ to .0015″ which is way within limits for my D16Z6 block.
