gazzaw Posted March 3, 2015 Share Posted March 3, 2015 Hi i am rebuilding my jeep engine and about to put in new (same sized) main and big end shells. What colour/ type of plastigauge should i use. i have green packaged plastigauge ( 0.007"-0.020") but the rods when compressed are red?? As far as I remember it was green rods that left a green/light green mark on journals and not a red marking. Has the green stuff changed to leave red markings now - this is a new sealed plackage they came out of. from the manual clearance should be 0.001" When I tried this stuff I got the following reading which seems wrong to me, all journals were approx same size on gauge gary Quote Link to comment Share on other sites More sharing options...
hummermark Posted March 3, 2015 Share Posted March 3, 2015 Hi, I think that you are using too larger scale as you say that your one does from 0.007-0.020" you need the red gauge which does 0.001 - 0.007. Regards, Mark Quote Link to comment Share on other sites More sharing options...
gazzaw Posted March 3, 2015 Author Share Posted March 3, 2015 thanks Mark Thats what I thought, what threw me was the green set has red gauge mark whilst I remember the green used to be green which was correct for the 0.001" - will order the red proper gauge -hopefully that doesn't have green gauge inside with a red check panel lol gary Quote Link to comment Share on other sites More sharing options...
Richard Farrant Posted March 3, 2015 Share Posted March 3, 2015 Gary, You need the red one which covers 1 to 7 thou. I recently got a new supply from RS Components so it is available. regards, Richard Quote Link to comment Share on other sites More sharing options...
