Jeff check your flame trap,it is a filter that is in a hose that goes to the large air intake hose that goes from the air filter to the intake manifold,the hose that the trap sits in usually teed into the large hose right before it connects to the intake manifold.Follow that hose down under the intake manifold and it will arrive at a junction that has a tee with a smaller hose connected to it that goes to the intake manifold,pull the plastic juntion apart and shoud find a element that looks like a cigarette lighter core.If this filter becomes plugged then the crancase will develope high pressure internally and cause oil leaks.You can order a new one thru IPD(www.ipdusa.com)for around 8 dollars for the entire kit which includes a new trap,hoses ect.
