I stumbled across a very clean, very smooth running 1989 420 SEL. One owner. 210,000 miles. Timing Chain changed at 110,000 .. It starts on the first grunt of the starter, less than a 1/2 second. No ticks, no leaks, no smoke. All maintenance logs, interior clean (not detailed to make it just look clean). The only odd thing is when I checked the oil, it looked very clean and I smelled it. It had a smell that I associated with a failing motor... hard to describe, but thin, almost like oil and hydrocarbons mixed.
I know that timing chains should be changed every 100,000 - But the 210,000 does concern me. I also heard if the chain snaps in these, you can bend a valve? Is that true that the 1989's had interference motors?
Thank you in advance for your opinions.
