Eynonz Posted June 26, 2014 Share Posted June 26, 2014 I asked this a while back and I was told that it should be 160 across all 4 for a healthy result. Quote Link to post Share on other sites

H_D Posted June 27, 2014 Share Posted June 27, 2014 The cause of the high compression will more than likely be due the head being skimmed to much in the past.When forging go for a 1.6mm or 1.9mm head gasket to bring the compression back down. Quote Link to post Share on other sites

AdamB Posted June 28, 2014 Share Posted June 28, 2014 Anything below 140psi requires a rebuild ideally. Providing results for each cylinder are within 1 bar or 14.5 psi of each other then it's fine. I personally wouldn't be using anything more than a 1.2mm headgasket on these engines, compression is already too low as it is imo. Quote Link to post Share on other sites
