I replaced the timing chain about 3 days ago.
It was work for the whole day, beautiful weather, lots of fun. :big_grin:0
The timing chain did not look worn as much (fraction of mm), all the guides were completely and nothing was broken, at that time I thought that maybe someone actually changed it at 60k. [picture 1 and 2]
After setting the engine in the right position and locked it I saw that:
- Inlet Camshaft is OFF about 5' (degree) [picture 3]
- Exhaust Camshaft is OFF about 3' (degree) [picture 4]
Because everything was unscrewed, I replaced the entire system with the timing chain anyway. [picture 5]
I measured the new chain with a BMW special tool and it turned out that in fact the old chain was more worn than it looked. (New chain 64mm)
Yesterday I have made more than 60 miles and everything looks that it is correct and the problem is fixed. I will check it on some longer routes as well.
The conclusion is as always; that you can not trust people and you have to take care of everything yourself. ::wink::
