87 dodge b350 ext with 5.9 360
When I bought it, I was told I needed to clean the heat riser. Not the one on the exhaust manifold where it meets the exhaust, but the one in the intake..
2 questions...
1- If your not in a cold climate, do I even have to worry about it...
2- If I should do it.. What is entailed in the job? Is it something I can do by myself or do I need to take it to a shop?
