Hi, New to the page and just recently switched from my stock oil pan to a moroso 7 quart. I left the motor sitting without oil for a week because I had to go out of town for the holidays. Once I bolted everything back together and added 7 quarts of oil I noticed smoke coming out from around the headers or spark plugs. Any guess what this could be? I'll try posting a video tomorrow morning, but any advice would be helpful. Car only ran for a few minutes as it's pretty late already. Also sounded if the car wanted to turn off towards the end of it running.
