Hey guys I just got a Volvo 740 turbo 1987 from my uncle that diesd. It has been sitting for 5 years. I cleaned the gas tank fixed the pump and got the car running. But when it runs for 30 sec the oil filter spits out oil. We blew air thru all the holeses in order to get gunk out and still doing it. What can my problem be? Thanks for the help in advance.
