Hawwy Posted July 9, 2013 Share Posted July 9, 2013 Compression results Efi removed King lead removedAll plugs removedEngine warmFull throttle i had somebody crank till it builds much compression as can and put foot down and i also push throttle pully downTest resultsCylinder 1 : 170psiCylinder 2 : 180psiCylinder 3: 170psiCylinder 4 : 170psiAlso for cylinder 2 i didnt push throttle pully all way down but was pressed from inside carIs this okay Quote Link to post Share on other sites
Flaminsam Posted July 9, 2013 Share Posted July 9, 2013 Yea seems good. I do believe any larger difference than 1 bar across all four cylinders would indicate a problem. 1 bar is 14.7psi. Quote Link to post Share on other sites
Ryan_EP82 GT Posted July 9, 2013 Share Posted July 9, 2013 Seems real healthy mate!Mines turned out at 140, 140, 140, 70 Quote Link to post Share on other sites
Hawwy Posted July 9, 2013 Author Share Posted July 9, 2013 Okay as when i took oil cap off and gives out smoke/steam and it goes away.But when i rev it, it does slightly give smoke unless its steam.But results are okay so. Quote Link to post Share on other sites
Ryan_EP82 GT Posted July 9, 2013 Share Posted July 9, 2013 When I take my cap off the oil shoots all over the bay.. And if I rev it, it pisses out! Quote Link to post Share on other sites
Hawwy Posted July 9, 2013 Author Share Posted July 9, 2013 It would because of the cams? When i rev it it does go everywhere but sprinkles Quote Link to post Share on other sites
Hawwy Posted July 9, 2013 Author Share Posted July 9, 2013 Only thing im thinking is what if on cylinder 2 if i held throttle pully down aswell it may be like 190 or something?I didnt hold it down on cylinder 2 , only accelerator was pressed from insideAnd for cylinder 1 it was 160 psi with accelerator down, but i did again with the throttle pully all way down it went to 170 Quote Link to post Share on other sites
mikey4410 Posted July 9, 2013 Share Posted July 9, 2013 (edited) around 180 is best u will ever get from these engines standard.checked mine and got these results a month ago. years ago when i bent a conrod one cylinder went down to 90 odd i think.i made a banana of the rod.

Sounds like this as it is only open under vacuum and closes under boost. So if your getting excessive vapour come out the oil cap it would indicate your getting excessive crank case pressure.

AdamB Posted July 10, 2013 Share Posted July 10, 2013 Maybe try an oil change mate, you might have some fuel or coolant floating on top of the oil. Quote Link to post Share on other sites
