If i can quote and correct some points would that be okay?
Since d24x powered engiens were pretty commonly used here on Finland on taxi's on 90's in 940series, and it had also it own fans in 80's too.
This is same problem as Mercedez-Benz had on w124/w210 on their 5 and 6 cylinder engines. Thing that kills both D24 and Mercedez OMxxx family is long idle times. Cylindergroup is so long at coolant dont cool anymore on last one or two cylinders
in idle enough anymore, neither oil pressure isnt enough to quarantee 100 procentish lubrication . These two compared together adds increased wearing to last two cylinders, and wears them to egg shape.
One solution is to raise idlespeed, which increases the oil and coolant flow.
Also every start wears d24, because the placing of oil pump,
few first second cylinderhead runs without/with low oil since pump needs to suck oil first from "oil storage" (lol what is the word).
To help to that case you can add 3 desilitres more oil as max.amount is without causing cranksaft to be in danger to hit oil surface in any situation.
Well, gone little out of topic sorry about that.
EDITED some really crappy writing and few other things.
