Hi i've got a bit of a problem. I've got an 02 jtd with 59k on the clock and its getting a lot of oil in the MAF. I cleaned the old MAF but it appeared to be creating a problem so I bought a new one and fitted it. I noticed the oil when fitting the new MAF. it appears to be carrying over from the rocker box breather to the air filter then into the MAF. Is there a filter in the crankcase breather system that would block and cause oil carry over? I am obviously getting smoke from the exhaust due to oil being taken through the air system. Any thoughts?
