im hoping keep it i love the car its only 150bhp but its such a nice drive

everybody i speak to say how good the engine is with it having larger exhaust ports and a smaller turbo so the engines apparantly last longer, im going buy a new MAF and lambda sensor just to see if it sorts out the flicker on idle and try clean the throttle body, the only other problem my car has got but its had it for quite some time is the turbo seals pass a drop of oil every now and then, i lose hardly any oil, but i can see where the leak is, and 4 mechanics have checked it over and told me, he sees it all the time on these 1.8 turbo's and its a common problem, but wont harm nothing is this right and anybody else had this ??
