Aloha,

changed the oil on the g at 176k with 5w30 mobil fully synth, its now on 178.5k and I've used 3 litres in that period topping the car up with oil.

it breathes heavily, but the charger pipes and intercooler have no more than a fingerful of oil at the most, just a light coating all around.

there is a spattering of oil remants around the bonnet where the oil breather vents to atmos, as the vapours condense on the bonnet.

I've had to top the coolant up twice (amount of the expansion tank) in 3.5k.

2 weeks ago when the car was started from cold, when setting off and on overrun (lifting off the throttle) there was quite alot of white smoke out the exhaust, enough to cause alarm to people behind me (best thing to deal with tailgaters), the smoke was gone after 5 minutes.

the last two weeks have been smoke free, just showing a very small puff of whitey smoke on gear changes, even when warm.

started the car today (-1/0 degrees outside), not been driving since friday night and we had smoke screens again (white smoke from the exhaust) until it had warmed up again.

the car was hit off the limiter twice at the awesome gti rolling road day, I've hit it twice by accident in 3.5k.

when the car was on the rollers at awesome and it hit the limiter, it kicked out a load of oil from the oil breather (as it vents to atmos)

car only smokes when cold, or on overrun or pulling off, doesnt smoke at all on boost and if you apply a bit of boost when cold, it doesnt accentuate the white smoke (dont use boost when cold, but just wanted to check if it made a difference)

charger was last serviced in june (full set of seals, kluber grease and new belt) and has done 8k since.

engine was fully rebuilt 28.5k ago with the following new oil pump, new rings, all bottom end shells, seals, gaskets and a thinner metal headgasket.

i will have one of the other cars for driving about in february but just want some input from you guys if you think the symptoms seem charger or headgasket based?

id be doing the work myself bar the charger seals which i would probably take to pete, but i have a spare dead charger to practise on first if neccessary!

cheers guys =]

added pics

plug 1 - looks normal

plug 2 - looks normal

plug 3 - looks normal

plug 4 - looks more carbon deposit based rather than oil based deposits (this plug being nearest to the dizzy).

done around 1k on those plugs

didnt get a chance to check compression today as the engine builder is moving into his new gaff!

might be hard to check while its on, but there aint a hairline crack in the head is there??? worth a look?

maybe a around cylinder 4 by the looks of it :(
