I have an LET engine and its started to smoke.
It is blue smoke and happens all the time, although sometimes it can appear white-ish.
The oil is going down quite quickly and when running low on oil (ie. not shown on the dipstick) the smoke lessens to almost nothing (not something I intend to test on purpose!)
I suppose it could be the rings, or head gasket, or maybe turbo...
How can I go about working out what is wrong with it, without taking it apart (too much)?
