good day sir, i am an owner of a jdm, 3door pajero with a 4d56 turbo intercooled engine. Would just want to ask if my paj needs a overhaul already. because at idle it emits a bit of white smoke and a certain smell. Does smoke condition improve when temperature rises?

also, the dipstick and oil filler spits some of the oil when i open it at start. along with that white smoke also comes out of the breather hose.

and i think my oil catch can is being useless since oil still gets into the intake, plus my fuel consumption is just 6.5km/l on city and hiway about 8km/l. which i think is very bad.

just an info, about 6 months ago, we replaced our piston rings since my mechanic suspected loose compression. its now oversized btw.

what do you suggest for me to do? Your post seems to indicate that overhaul is the fix. Check piston ring groove width, replace if worn; replace piston rings, and resleeve cylinders to standard size....
