Yea, the mechanic (my neighbor) that is helping me with the project said that since we don't know how long coolant has been in the oil and that after we are done something in the bottom end will go out (like a bearing). But I am not too worried about that because I am going to sale the truck in April. I am serving a 2 year mission for my church and my parents said I have to sale any vehicles before I leave. When I get back I am planning on buying a 1st gen Tacoma so I have a vehicle to drive to colledge. After I am out of colledge and get a good job I want to buy a solid axle toyota (probably 1st gen) and make a crawler.
