You're mainly looking for the difference between the cylinders, a difference of more than a bar between two or more of the cylinders is not good. Remember to crank it over with the throttle wide open too (and disconnect the fuel pump) Quote Link to post Share on other sites

A L 3 X Posted August 18, 2012 Share Posted August 18, 2012 (edited) I think maybe youve got a duff tester especially to have the exact same across each cylinder and still running perfect, is the smoke blue or thick white?If your getting no oil out the breathers or take the oil cap/ dipstick out when running and see there, shouldn't get much more than a few spatters out the oil cap and nothing from dip stick, you using any oil?If all signs seem good swap back to your other turbo and see what happens mate, something sounds a bit strange. I had mine comp tested on a cold engine with king lead on and a shit tester, mine was low but due to the test not being done at right conditions, but was a lot higher than yours and was again exact across all four though Edited August 18, 2012 by A L 3 X Quote Link to post Share on other sites

A L 3 X Posted August 18, 2012 Share Posted August 18, 2012 That's what I'm hoping for you mate, I only had slight oil in my tmic but nothing in the fmic or so it seemsAnd again just dry black soot in the exhaust, but I've been told unless its pissing oilOut the seals the exhaust side won't get oily as it just burns offAlso if your compression was that low I'm pretty sure you'd have running issuesI'm not 100% but it's better than stripping the engine down just yet mate Quote Link to post Share on other sites
A L 3 X Posted August 18, 2012 Share Posted August 18, 2012 Also mate, when you say you primed the turbo and cranked it with oil return and king lead off, what do you class as priming as I always assumed that was priming but I'd like to know for when I fit mine?Cheers Quote Link to post Share on other sites

But id dont!Also mate, when you say you primed the turbo and cranked it with oil return and king lead off, what do you class as priming as I always assumed that was priming but I'd like to know for when I fit mine?CheersMy head was up my aress yesterday so didnt realy know what i was saying haha..The best way to prime the turbo is to crank the engine a few times with the king lead off as it still pumps oil into the turbo without the turbin spining fully!..I crank it over about 3times i.e turn the engine over let it rest for 5min then turn it over again let it rest then finaly start the car!

ro55ifumi Posted August 19, 2012 Share Posted August 19, 2012 To prime the turbo leave the oil return off and remove king lead turn over engine, oil light should go out whilst doing this and when oil starts to run out the oil return you know the turbo is primed, fit the oil return pipe an you are good to goI get someone to turn it over whilst i watch the oil come out the return and catch it in a container ;)John Quote Link to post Share on other sites
