[T86951]

my shop, when they did my belts on my 951, says my external oil cooler is leaking a bit coming out the the engine and a bit at the oil cooler both. Not a lot just a bit. Would this be the O rings on the lines?

anyone have any experince with this. I guess this is where the half quart of oil goes between oil changes which is about once a year as I only put about 5000 miles a year on it in the summer and keep it garaged in the winter.

thanks
