I'm not getting a lot of work done on my car this winter. Its been so mild I keep driving it every time I open up the garage to work on it. I'm getting oily soot on the outside of my intake runners, clearly burping out from the joiner hoses at the manifold. Why is it there, and is it something that I need to be concerned about? Zach |

You have a wire unhooked. How old are those hoses? Are they hard and not sealing?

QUOTE(Krieger @ Mar 4 2020, 11:10 PM)  You have a wire unhooked. How old are those hoses? Are they hard and not sealing? The wire is the grounding wire that you use to put a new firmware on the ECU. The hoses may be 45 years old. They were on the 1.8 parts I got from Joe a decade ago when this engine was built. If the engine is backfiring I don’t hear it. But it’s certainly possible. Zach |
