[Ekus]

I've tried several timing advances past days, engine did smoke white with 0.95mm. I finally set to 1.10mm, surely pump is not in perfect shape and that's the reason why it needs so much advance, but engine sounds and run perfectly there. I've tried more advance but overall impression was bad, 1.10mm seems fine for that old pump+higher pressure injectors(185bar).
Engine still having a gray/white haze that does not dissapear with the smoke screw adjustment in the pump. Engine is not missing coolant, and smoke has not blue colour and smells like diesel. I found that two exhaust valves have not clearance at all, meaning that they never be closed at all...
do you think that compression lost in two cylinders through the exhaust valves can cause the unburnt fuel make that haze?
or it will be a worn pump instead? Engine pulls nicely, sounds great, idle is smooth.
I will ask for adjusting discs on a vw dealer tomorrow...
