Smitty 77
I had a small exhaust manifold leak in my ISL last year. I had it repaired and headed off to Alaska. All was well until we reached Edmonton Alberta when I noticed a oil film on the back of the coach. After investing where the oil was coming from I found a small hole in my dipstick tube close to where the manifold is located. It was determined the manifold leak had been blowing out on the tube making it soft and after driving 2K miles it finally blew a small hole in the side of it. The service center ordered a new one from Spartan and when the technician installed it, I had him split a small heater hose and put around the new dipstick tube so this problem would never happen again. Might be something you may want to consider.
