Hi all. I'm new here. I'm fairly clueless when it comes to the inner workings of my vehicle, or any vehicle for that matter. Been pulling what's left of my hair out after the last 18 months of troubles with my bus.
2006 T5 VW Caravelle 2.5tdi 128kw (auto)
Milage ± 200 000kms
Problem started some time ago with leaking oil, losing water, and white smoke. Diagnoses was a cracked block and gasket replacement etc. Block was repaired.
Work done over the last few months:
Head was skimmed and a pressure test was done
New valves and stem seals done
New pistons, rings, and bearings done
New glow plugs
New top gasket and water pump
Compression test done (status: good)
PROBLEM: The van
still smokes excessively. Edit for clarity: Thick 'clean' clouds of
white smoke. Mechanic says there's no particular smell to the smoke, and the smoke seems to disappear at a higher speeds around 100km/h but as soon as the van idles at a standstill the smoke is back.
It's been to numerous people for a diagnosis and nothing. Any ideas on what the underlying issue might be?
