I have the car back since last Monday night. Drove the 200 miles return trip at a calm speed to bed well the new con rod bearings. The engine now sounds smoother than before.
Before I left he showed me the old bearings and they had identical wear and were still in good shape. My mechanic did notice that the con rod bolts were a bit stretched compared to new ones.
He didn't have time to replace the left track rod end before I went to get the car. He also noticed that the front sway bar bracket bolts were a bit stretched and that I didn't take new ones for him to replace. I had to look up online the part numbers since ETKA isn't very explicit to indicate which are they (they're not represented in the side picture). I ordered them later after I found a topic about them.
Yesterday I took the car to a local friend who replaced both track rod ends (the left one was really busted and the right one had a small tear that wasn't obvious to see) and replaced the front sway bar bracket bolts.
The list of parts replaced in this maintenance is a bit bigger now:
-Diesel filter (116 mm) (1K0127434B)
-Oil filter (071115562C)
