I suggest you take the oil lines off. I broke my oil cooler and oil line removing/installing the headers with the cooler and lines in place.Roulettetriple said:My pipes are brown, so I know I've been pretty warm, just looking for the best looking, and somewhat cost effective way to coat the pipes. The duplicolor probably isn't all that different than the coatings on the website you listed. When you pulled off your headers, did you have to disconnect the oil lines, or just taking the bolts out gave you enough clearance?
