The Solution to oil burring in ISUZU V6 is a clogged EGR tube. Tube is located inside of intake manifold.
1, Take out, I think it is call mass air flow! it is in front of intake manifold. Four bolts and few vacuum lines. Not that bad.2, Take out EGR Valve.
3, Take a new can of carburetor cleaner. Clean the tube that goes to EGR valve from the front side not EGR side. Tube will be inside intake manifold. If you have Shop Vac you can use it to suck from EGR side.4 Last take a long brush, which is use for cleaning oil passages, and clean the tube thoroughly. (Auto parts store, I got 5 brushes for $10) you need only one.
5 Assemble everything and you are good for another 40000 miles.KALIM KHAN
