Got a Mf 135 with a Perkins gas engine. I have being restoring and replacing for a month. Looking over the engine I got to wondering about replacing the vent tube with a pcv and routing to the air box. When the engine was built in 1973 gas was 25 cents and dumping excess down the front of the engine was no big deal. But at 3.29 a gallon can a significant improvement be had in routing the unburned fuel back through the intake? Would better ventilation make oil changes less frequent?
