I have no visible oil leaks but I do have some blowby going on but not excessive. The truck runs good and strong and this problem has not gotten worse over time. I have the truck serviced every 8000-10000 miles. Anybody got any suggestions?
oil could be leaking into your fuel system... have you looked in the tanks for dark fuel?
