When I had my d12 my dealer ( my dads uncle Owens the dealership) told me they were bulletproof. Even though family owned the dealership I could not get past the ride. A lot like it I did not. I prefer to feel the road and not have a breeze sway your cab. Most of all lack of power mine had.

I'm usually not pulling heavy so lack of power is not a problem, last year I averaged real mpg of 7.5 month so was very happy with that. Volvo's do like to sway in the wind though. On the D12 you have to jack the frame up to get the oil pan past the front axle but that may be what needs to be done.
I pulled another oil sample going to send it off tomorrow, along with the one I pulled when I changed the oil last time and have them tested/retested. I tried watching the water pump weep hole and no coolant came out by just revving the engine, but today it didn't leak at all, compressor cycling or not! I did see a few bubbles come up in the coolant tank when the compressor first kicked in. I think the head gasket is just starting to go on compressor but should get one of those things that you check for compression gasses in coolant I guess and make sure. -

That's why I am ok with less power I like it to go in my pocketbook instead out the stack.....

I will have to check the air dyer, I did drain the airs tanks and nothing unusual there. Thanks

To the OP.
Don't know what year your truck is but I would say the EGR Cooler should be checked if it hasn't been. That is what it was when I had a D12.D12 Owner Thanks this. -
You had coolant in your oil? My egr cooler is blocked going over to the intake side and both coolants lines going to the egr were blocked but have come to find out its possible the rubber plugs used may worked loose.
