Hello fellow powerstroke owners, I have a 97 obs f350 with 219,000 miles on it. I have replaced the oil pan and recently did the injectors. Prior to replacing the injectors I had virtually no blue smoke or blow by, now I have both. Since I am doing some body work I haven't gotten around to looking at this yet. My question is when I replaced the injectors could not torquing the injectors bolts all the way cause these symptoms? Or could it be a o-ring that got damaged during installation. I had made sure to put oil on them when I installed them. Any help would be very appreciated. Thanks.
