Hello, I have a 07 Volvo D13. The engine is mixing Diesel with the oil.

Mechanic's Assistant: What's the make/model/year of your truck? Engine type?

Volvo D13 2007. I have changed every thing i can think off that would cause that problem, including injectors. My last thing is to change the cylinder head. Is it possible that the cylinder head could have a crack and cause this to happen?

On your question, I have not seen a crack in the head that would cause this. The fuel galleys are deep in the head and that would be very unlikely that the head is cracked in that area. One thing I have seen a lot of is the fuel galley plugs leaking. If you pull the valve cover off and look behind the gear in the back of the head you will see 2 threaded plugs. I add an entire bottle of fuel dye to the filter and run the unit for about 10 mins and check the overhead with a black light. That seems to work the best. I hope this helps with your issue. Thank you

I have just been informed that new injector sleeves have been fitted, but they did not put the washer on the injector before installing. Could this cause the same as i would say the injector is sitting lower into the sleeve and not sealing the diesel properly.

That should only cause a hard start. Those need to be on there though

It does have a hard start as well.
Technician: Mike Mcmillan, Shop Foreman/Triage Tech replied 1 year ago
I would reseal the injectors and perform the black light test
