I take it you have the carb 4.2? There is an emissions hose coming from the top of the valve cover into the air cleaner assembly. On the valve cover, there is a PCV valve to help keep most of the oil where it belongs (inside the engine. Now alittle will still get through due to the vacuum of the intake, so there is a small 'sponge' filter inside the cleaner housing to get the rest of it. Both of these items should be replaced every 12,000 miles, or every year. Total, the parts will run you 5-6 dollars depending on where you get them. Hope this answers your question. Josh
