Hawwy Posted July 31, 2013 Share Posted July 31, 2013 Very low compression Quote Link to post Share on other sites
Flaminsam Posted July 31, 2013 Share Posted July 31, 2013 Yea 6.5 is low on compression. You should be looking around 10bar at least with no greater variation of 1 bar across all four. Quote Link to post Share on other sites

AdamB Posted July 31, 2013 Share Posted July 31, 2013 That's very low compression. Did you try a wet test? Quote Link to post Share on other sites
FrancyGlanza Posted July 31, 2013 Author Share Posted July 31, 2013 yeah ino compression is very lowdidnt do a wet test but i may to see if its rings but i dont tink it iscould timing affect compression ? Could Be valves ? stem seals ? Quote Link to post Share on other sites
AdamB Posted July 31, 2013 Share Posted July 31, 2013 The engine timing will affect the compression yeah, but that's clearly not your problem if its burning oil. Sounds like a ring sealing problem to me, could well be valves but it would be very unlucky to happen on all 4 cylinders. Quote Link to post Share on other sites
Danb Posted July 31, 2013 Share Posted July 31, 2013 comp test done with WOT and on warm engine? Quote Link to post Share on other sites

Danb Posted July 31, 2013 Share Posted July 31, 2013 If throttle was not wide open then pressure results will be low (like yours) Quote Link to post Share on other sites

AdamB Posted August 1, 2013 Share Posted August 1, 2013 Do the test again with WOT. Quote Link to post Share on other sites
FrancyGlanza Posted August 21, 2013 Author Share Posted August 21, 2013 Test done with WOT and reached just over 7 bar would the 1.4 headgasket not make it as low ? for a car that has low compression it pulls like a train Quote Link to post Share on other sites
FrancyGlanza Posted August 22, 2013 Author Share Posted August 22, 2013 Got a compression txt with another tester and came 10 bar cross all four :/ Quote Link to post Share on other sites
FrancyGlanza Posted September 5, 2013 Author Share Posted September 5, 2013 Any anything else ?Still doing thisCompression was done again twice with two different testers both came up 150psi across all cylinders bang onBoth side of turbo are dryDoesnt smoke on idleSmokes abit on boost and as you come off it and put throttle back down puffs a smoke comes out I think myself it is valve seals but want to be sure ? but they were only done ?
