    Ok quite simply I'm burning through oil and i'm sick of the smoke, the mess on my rear bar and the constant cost of oil.
    So i want to know is there and simple way to diagnose what's screwed? i figure it's either my oil rings, valve stem seals or a head gasket problem but i'm not a fully qualified mechanic so i really don't know. Also i don't want to replace the head gasket and valve stem seals if they're fine and it turns out my oil rings are farked coz that'll drive me absolutely bonkers, anyone got some ideas?

    do a cylinder leakage test. that will tell you EXACTLY where your problem lies....

    Oh right yeah one of those.......um... How?

    I did a compression test today which i realized while doing that i'd never done to this engine, wish i hadn't now, the results are what i refer to a catastrophic.
    I remember my ADM read close to 160 across all cylinders, after these reading either I've had a shit load of wear in the past few onths or the guyi bought the engine off and the guys who installed it did a dodgy on the compression test.
    Cylinder #1 150
    Cylinder #2 130
    Cylinder #3 120
    Cylinder #4 150

    I don't like the looks of Cylinders 2 and 3

    basicly its a gauge (and an expensive one at that) you screw into the plug hole, you spin that cylinder to the compression stroke (take off the valve covers, makes it a lot easier) next you apply your air pressure the (line is a part of the leakage test gauge) , you will need one of your "trusting" friends to have a socket on the crank pully, (3/4 and a johnson bar) to prevent the air pressure from just spinning the engine backwards, watch out though, if he lets go, it will hurt lol then you turn your dial full open, and read the gauge, if its ANY less than 95% sealed you have a leak, drop the pan, and listen, listen by the cams, intake, tailpipe ect.. and that will dictate your leak... a stethoscope is a handy tool for this.. good luck...

    you didn't do the test right. it would run horrible all the time with those numbers.

    Well that could be good news, it was a pox tester you gotta really hold it in cause it's not a crew in one, perhaps i should invest in a proper one or get my mech friend to track a good one down for me to borrow.
