Verslagen and I were both able to identify where a leak comes from, by hooking up the vent tube at the top of the cylinder cover - to an air compressor to pressurize the crankcase (I only had 5 psi in my compressor).  Once the pressure is applied to the engine, I used a spray bottle to apply a dish soap/water mix, and then I watched for bubbles.  It worked very well to identify the leak.  If your head cover is the source of the leak....then you might as well put a Verslagen head plug in while you have the cylinder head cap removed.



Also.....the left front cylinder had stud can leak oil from around the washer - that stud has an opening around it, and it functions as the drain for the oil from the cylinder head.  If that is the source of the leak, remove the nut, clean the nut and cylinder head, and then apply sealer to the nut.  The threads on the stud should have never seize applied, then the nut needs to be torqued.

I had some family health issues I had to deal with.  I appreciate the help so far.  With the test prescribed it looks like it is leaking from both places. But more from the top.  It looks like a head cover problem is the main culprit.  That means I have to remove the engine to repair it correct?
