2007 Volvo D12 coolant in oil

Wow 1.9, I knew a guy with 1.6 and no overhaul but he did have quite a bit of blowby so he ran a tube to back of truck. (the D12 blowby tube sits pretty high and any fumes/dripping gets blown on the tranny)

 

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

 

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.
