You can buy just the seal for the oil fill cap. They eventually dry up and don't seal properly. We replace them as part of every 30k mile service. Now if you think the pcv system is plugged up, you may want to have it checked out. Usually lack of maintinance causes sludge build up. If this is the case then you will need to replace the oil trap box and make sure you clean out any sludge build up on the bock and also clean out the banjo nipple that is attached to the intake. You need to be very carefull not to break the nipple since you need to remove the intake manifold for this repair and the banjo is on the bottom and hard to get it. If it breaks then you will need to replace the whole pcv hose assembly and that could be a little pricey.
