It does not burn any oil or smoke but it does have some cam and lifter wear.(no lifter noise after valve adjustment). Small amount of front and rear seal leaks even after replacement. Oil pressure is low when warm at idle. Would I benefit changing to 10w40? Posts show various opinions regarding oil. I live in Virginia.
Thanks,
Howard | | |
