I hate to ask but water in oil (using water 1/2 gal per oil change water never in oil for 3 years) using 1/2 gal in 80mi so I changed the head gasket/oil+filter ran the truck 54mi turbo failure water in oil not much but did I fix the problem? the question was in my mind. changed turbo/oil+filter ran truck to work used 1/4 gal 100mi is this burbing and me parinoid? or dose any one not think the head is warped. I pulled a small trailer empty and it started over heating that was the reason for the gaset change.
