TrisK Posted July 9, 2012 Share Posted July 9, 2012 My mate has had white smoke and stutteringSo got him to do a compression testHe got (in bar)1: 9.72: 8.63: 7.84: 8.2What do you guy make of that? Basically after a ragging till smoke white and thick after stopping for 30 seconds then clear and be fineHe also claims its flat boosting although his guage is showing a solid 1 barWhat do you guys think?Results seem a bit all over the place Quote Link to post Share on other sites
AdamB Posted July 9, 2012 Share Posted July 9, 2012 Probably headgasket mate, they are all over the place. Did he do a wet test? Dropping oil down the bores to eliminate the rings. Quote Link to post Share on other sites
Flaminsam Posted July 9, 2012 Share Posted July 9, 2012 As a rule of thumb I always go for if there's a difference of over 1 bar across all four cylinders there must be something wrong. Do you have access to a bore scope? That would give a better indication of the problem. Quote Link to post Share on other sites
