I came back from a flight and there was a large puddle of oil under the engine. I opened the oil door on the upper cowl and saw the right hand pin that holds the cowl in place sitting on the battery. It turns out the pin had shorted between the battery and the oil pressure hose. The hose has a large leak. I obtained new hose and will assemble it and install it soon. Vans drawings do not show a retainer for the pins at the firewall. I know how I will make retainers for both top cowl pins and that will be done after I clean up the oil mess. I lost only 1/2 quart but that does make a big mess. I see the advantage of modifying the cowl attach to 1/4 turn fasteners. I am confident the vertical pins on the side of the firewall will not be a problem.
