Greeting Everyone!
85 190D 2.2 White, Clean No rust with 211,000 miles

I have had the pleasure of owning my 85 190D 2.2 for about a year now. Recently she'd been sick. I had to replace glow plugs and engine Fuel Nozzles. All was fine for about 2 weeks when suddenly my baby benz temp jumped to 100c (with the radiator water level light on) about 1 mile away from home. She never overheated but started to blow a heck uva lot white smoke. I waitied till the car cooled down and re-plenished the coolant. Drove home (the temp stayed around 100c). I got home 5 minutes later and she started blowing the smoke and running really rough (like the horses in the engine were pissed off....

-I changed the thermostat...same issue looked in expansion tank and visually saw a little oil at the top of the coolant layer.
-Hoses were rock hard at start up and never got soft.
-Shutdown and after 2-3mins hoses got soft.

I search some of the threads here and could not find anything about (white smoke).

Is this a common thing with a diesel M/B with over 200k? Should I atttempt to change the head gasket or if its a cracked head (machine remanufacture) or replace? Some tech told me if I change my head it might ruin the rings and engine. Should I attempt to rebuild entire engine?

I love my M/B and I want to do right right by her not retire her....

I have read a lot of posts and they were always on point. Thank you all for the dedication on this forum! I feel you guys are the guru's of the M/B world...So plz help!
