Is any one using blue when they check ther tolerances, or should I just plastigage?

any builders out there? need some help getting my engine back together properly

Just a guess but you would probably blow your motor using all blues

I mean bluing agent to check for even contact between journals

this might sound crazy, but the best policy is to measure the tunnels with an accurate dial bore gauge, and to measure the journals with an accurate micrometer. Your measuring tools need to have resolution of one ten thousandth of an inch. I just had this argument with someone on here a couple of days ago. To me plastigauge is just a sanity check, the best and most proper method is to measure, then order the proper bearings, then plastigauge to make sure you measured correctly.

As far as using layout blue to check contact, that would not do any good on the journal side, but some builders use layout blue on the back side of the bearing, and the tunnel bore to check to see if the back of the bearing has even contact with the tunnel.

Short of having a micrometer, a quick/not-neccessarily-accurate way would be to plastigage 6-8 positions around the journal to "map" taper and out-of-round.

Or, just bring it over and I'll mic and look it over - free of charge.

Thanks Jim, but I'm trying to do the build myself. If I did that I might as well bring you the rest of it too lol. Did you get my E-mail about the pics.

Yes, did get your email. Thanks.
