@dnewton3 - thanks for the reassuring post :-) I am definitely planning on doing another change in say 2000km - perhaps do an oil analysis at the same time as well. The silicon source is most likely the crankcase breathing pipe that was left off by a dealership :-( It is getting its annual...

Why do used oil analysis if you can't worry :-)

Originally Posted by Cressida My guess is there was/is something going on beside that slight increase in dust that caused your wear numbers to bump. Let's hope it was, and not is. In fact, it got four new injectors last year courtesy of VW - starting with a bit of smoke. One injector was not...

UOA done on my Volkswagen Amarok 2.0 TDI. This is the fourth yearly analysis - always done before service. Things were ok for the previous three. Now, however, things have gone horribly wrong in my opinion. Diagnosis from wearcheck: Cylinder/liner wear rates are high. Piston and ring wear...

I worked out: 7.1 litres of oil if changed "wet", and 8.1 litres if filled from "dry". Thus 1 litre of oil remains during a change. The vehicle had a fuel-in-oil issue before - and a 2 % dilution on the current 8.1 litres is approximately 162 ml of fuel. *If* the current fuel contamination is...

I made a mistake - the fuel percentage is actually 2 %, NOT 5 % .

I am looking at buying this vehicle, and did an oil analysis on it. Herewith the results. The vehicle did have an injector leaking / cracked head problem before, but this has been corrected (new head, new injectors, seals etc.) and oil has been replaced 3800 miles ago. The only worrying bit is...

Thanks Jim! It's running a standard paper filter, but I will definitely check out the whole air intake system to make sure it is intact. The crankcase ventilation system on the Disco 2 is from the tappet cover into the plenum, and into the throttle body - will check them too. The diagnostics...

Phoned the diagnostics department of Wearcheck this morning, and after chatting got the following revised diagnosis: ---------- Wear rates are normal for a unit bedding in but higher than normal silicon (dust) level in the oil - check air intake system for leaks and for defective oil filler cap...

Second analysis done on this engine... does not look good to me. Engine was overhauled at 199100km, oil changed at 200100. Mileage now 208400, engine in use 8300km (around 5200 miles). I have an engine monitoring system that tells me the engine has been running about 150 hours since the last...
