After doing headstuds on my truck, I have a few problems. One is when starting, it stumbles then runs fine. Rail pressure builds quickly still, cranks for 3 to 4 seconds then starts but sounds really bad for a few seconds then is fine. It's much worse when warm. The other issue is I have oil coming out of the stud on the passenger side thats not under the valve cover. I may be getting some fuel in the oil too. And can't find a coolant leak on the passenger side. I'll start digging into it in the next few days. Just want to see if anyone has any ideas. I'm thinking maybe that head didn't seal properly for some reason. New heads were put on. Thanks in advance.
