Group: 26Number: 91-06
Date: 10/25/91
Subject:
Rasping noise From Exhaust
Model(s):
All 100
M.Y. 1992
Condition:
^ When the exhaust system is cold and the RPM is increased, a rasping noise can be heard at the end of the tailpipe. There is no rasping noise when the engine and exhaust system is at operating temperature.
Cause:
^ The exhaust system is designed to extract water from the exhaust when the system is cold to reduce corrosion. This design feature may cause a slight change in noise level during engine/exhaust system warm up.
Service:
^ Inspect exhaust system for leaks, i.e. round clamps and fittings.
If no leaks are found do not replace components or attempt to repair.
