Just to follow up on my "new" secondhand 190 D 2.5 1987:
I purchased it in feb. 2004.
1. two oilchanges within first month - and oilfilter
2. changes top gasket myself - naturally - Marth 2004 (oil in coolant!)
3. april 2004 oilchange and oilfilter-change.
4. may 2004: engine flush:
Drain and fill up with:
- 2 liters of dino oil
- 5 liters of diesel oil
Run engine for 30 seconds idle.
Drain and fill up with 7 liters of good prefered oil like 5W50 synth or
dino. I use 10W50 synthetic.
5. may 2004:
added Redex injector clean additive and later ATF oil to fuel.
6. adjusted the gear and speeder linkage.
Now I am getting a Mercedes Benz. No more no less. No rattles and no
bi-sounds left - almost.
Might give it more ATF within this month.
