Re: VW Transporter AXD 2006 - Engine tuning over feels like hydro lock #

I've changed a few camshafts and followers on AXD engines now and not always on ones with high mileage (96k) or when the incorrect oil has been used. The last one I had in sounded tight on one cylinder as it cranked and it turned out to be because the lobes of the cam had worn round after wearing the surface of the lifters until they were 'punctured'. No unusual mechanical sound when running on this particular one by the time I got to see it but you could tell it was running lumpy. I don't know how healthy it sounds to you when it is running but the fact that your oil/water mix is only apparent in the filler neck and not on the dipstick would suggest more condensation from short runs than head gasket to me at the moment and possibly the coolant leak is unrelated. Don't want to send you down the wrong path but just wondered if you felt it sounds and feels nice and level when running. You might hear/feel it blowing back through the air intake pipe at the air box as a quick check. On the other hand I have a 2.0 petrol Audi A4 in at the minute with similar starting symptoms and that is leaking coolant across the gasket into cyl 4 but was easy enough to find with the videoscope down the spark plug hole. Without the aux heater running, does your vehicle always have hot air from the blower? Head gaskets on these tend to air lock the matrix. Liam
