Hi .no this is a problem with the crankcase recirculation. in all vehicles a certain amount of exhaust gases escape past the piston rings into the crank case this is then fed back into the induction system for reburn and expel.. This type of system normal has a pipe that runs from the lower part of the block and into the air filter housing in the middle of this is a gauze type filter that gets blocked clean this or renew . regards rob
Thankyou would this increase the oil preasure.
