bigbloodyturbo Posted September 24, 2008 Share Posted September 24, 2008 they should all be pretty close, did you try pouring a drop of oil in the last cylinder and redoing the test? Link to comment Share on other sites More sharing options...
tooquicktostop Posted September 24, 2008 Share Posted September 24, 2008 I think I am right in that #6 is the most likely to have issues and yours is a little low, not a total loss however as a 10% spread is ok I think Link to comment Share on other sites More sharing options...

miko_supra Posted September 24, 2008 Author Share Posted September 24, 2008 Are they too low then? I just used a friends cheapo one so i'm not sure how accurate they are Link to comment Share on other sites More sharing options...
SimonB Posted September 24, 2008 Share Posted September 24, 2008 The actual values are not so important as the variation between them. Cheapo gauges don't always read correctly. The difference between your highest and lowest values is 20psi or 13%. 10% or less is what you want really. So it's not good but not a total disaster.

Guest Budz86 Posted September 25, 2008 Share Posted September 25, 2008 Thanks Simon I guess i might go for a rebuild over winter Compression test just seems like an excuse to do a re-build! Link to comment Share on other sites More sharing options...
Dazzi Posted September 25, 2008 Share Posted September 25, 2008 Thanks Simon I guess i might go for a rebuild over winter This is why I opted out buying a TT engine, you don't know where its came from or what condition its in Link to comment Share on other sites More sharing options...
