1989 Midliner MS250 Smoking

[missionsminded07]

So we have a 1989 Midliner MS250 with only 170,xxx miles on it that we use only 6-8 times a year primarily in summer on flat land, and no matter how long we let it run i continues to release smoke. What could potentially be causing this?

I'm still a newbie to the bigger truck things as I've only really dealt with my Saturn before

is it glazed a bit from idling to much sounds like its something simple like does it smoke much when working hard does it drink much oil ??

oh yeah welcome to the dog house

We had a few 89 CS200's. For some reason they (blue haze) smoked for ever with low mileage (200,000kms) but you couldn't kill them if you wanted to. Ours didn't have an oil consumption problem but as they warmed up they smoked a little bit less. Being city trucks they didn't work real hard and idled a fair bit. If you dont have an oil consumption problem it's most likely glazed cylinder walls or weak/leaking injector nozzles. Being an 89 it probably has a crap load of idle time, it's probably due for both an inframe and injector replacement. Parts will be expensive and possibly difficult to find. Only our 89' had that issue. I think it was the 06.02.12 Renault engine. None of the other Midliners we had ranging from 89-99 model years had that issue. It may be the engines from that period had blue smoking issues.
