Oil catch tank vs PCV/breather

[RICK LAKE]

951mat Mat if you do 95% street driving, the PCV system will work just fine as long a you have a breather for each valve cover. If you get the racing bug, you might want to go to the tank. For racing, autocross and roadracing. I run just a PCV on my car with a breather in each valve cover. They are the tall ones. I also have resistors in both heads for oil control. I run .080". This allows my heads to fill with oil, but not overfill to the tops. The oil was checked at 3,000rpms. The valve springs are covered and the oil is draining back through the return holes and pushrod holes to the valley. If you go racing the tank might be the way to go. I drive street classes. The pros use both tanks and vacuum pumps on there motors. You can test your motor for pressure with a vacuum,pressure gauge. If you hold vacuum at 3/4 throttle, stay with the PCV if you go to pressure, you may want to add a tank and drain. Do you have any blue smoke coming out of the side pipe on hard turns? if not, PCV will work fine. For the worry about the oil mist getting into the cylinders, there are orifaces to control this. The gas mist will mix with the oil mist and burnup. I would worry about this unless you are running a 13-1 compression motor. Check the spark plugs after 500 miles and see what color they are. Then you can go them there. You might want to think about adding an Accusump to your car as a peroiler for the motor and protects it if you go racing or pull high G's in autocross or roadracing. They come both manual and electric. You can mount it under the hood. I my case it has saved 15k motors. Just a thought. Rick L.
