Just bought a 73 914. Previous owner has resealed the engine. No noticeable oil leaks. Also the outside of the heat exchangers are very clean.
Problem: The inside of the heat exchangers have oil in them. When the engine gets hot tons of smoke comes bellowing out of the heat exchangers. You can actually hear the oil crackling and burning. Is there anyway to clean all of this oil out of the "inside" of the heat exchangers without taking them off the car or will this car always smoke with these on the car |

Pull them so you can verify there are no cracks or holes in the actual exhaust pipes, especially if they're stainless steel HEs.
You can perform this test by pressurize each pipe, or pulling a vacuum through each pipe to verify they're is no leakage ... then spend the money to have them hot tanked as previously mentioned. Peace of mind is a wonderful thing (IMG:style_emoticons/default/idea.gif) |
