I am having problems with my system. No water in the oil, oil coming out of the oil filler hole, when open, puffs of white smoke. Dripping oil from the oil filler. Sounded like a valve that is stuck. Havent found it yet. Oily number 1 plug. Ran great, then started to miss. And ideas on this problem? I changed a broken valve, it was a pain to monkey it into the hard plastic line. Any help is good. Thanks
