Hello all.
I have a 190E 2.3 (1991-2), 8 valve. I don't know what type of timing chain and tensioner does it have. It has 188.000 Km on the clock. Should I change the timing chain?
And... should I expect a noticeable effect on performance when I change it due to its wearing and the timing error it can produce? (basing on this number of kms and the fact that it has never been changed)?

Thanks!
