Hello,
I am back with some back news. The car started producing a strange noise, it can be heard like knocking, and vibrations occur every time when the engine is at 1800 RPM. The vibrations occur always, no matter what the load on the engine is, whether it is in neutral or in gear, the clutch pressed or depressed ...
I took an oil sample from the dipstick tube, the oil only has 2000 km but I sent it for the analysis this week. But it seems the analysis won´t be done this year yet, because the shipping times are very long these days during corona lockdown.
Anyway, because I pumped out a little too much oil I put the rest of it in a crystal clear glass jar. I washed it several days before and dried it, it was really spotless. now, as the oil was sitting a few days inside, I see the deposits on the bottom. I have no idea what that could be. Could this be metal contamination? I have no idea any more. The tubing that was used to collect the oil was also crystal clear and clean, the pump was a vacuum pump with no direct contact with oil. And since I have a lot of waiting coming for the oil analysis to be done, these time are really not fun at all anymore ...
Deposits can be seen below on the attached picture. If anyone has had onfortunate circumstances to deal with metal conamination in oil, then please tell me whether this seems like metal contamination or not ... And the oil only has 2000 km on the clock. You would expect it to be spotless.
