Quick question. I'm building my block and went to my local parts store for some supplies. Having never used Plastigauge before, I simply asked the guy behind the counter for some. What he brought me looked like everything I'd seen on HT so I didnt think twice about it. After putting my main caps on and torqing it down, I realized that the clearances shown on the Plastigauge package werent even the clearances I was needing. Then when I started looking around on here again, I noticed most people had green Plastigauge while mine was blue (this may explain why everything looked so tight). So my question is this: Between the different colors of Plastigauge, are the crush characteristics different? For example, is blue softer than say the green (making it crush more?). Or is all Plastigauge the same and only the reference chart on the package changes? Thanks in advance.

Hey man, you need to use GREEN ONLY, the red is meant for Industrial use on machines and things like that, ive never seen the blue personally, but you need to make sure its GREEN or your measurements are going to be way off... Just go to an Auto Parts store and pick some up. I think i got mine from Car Quest. Hope this helps

 

Thanks man!
