Thanks all for the respopnses. All of my valves are pot metal / aluminum and not plastic and I have the two in the rear and one in the front. I have changed the valves out before but never had this kind of a problem. Never thought of the WD-40 but will give it a try this weekend and let you know if it works.
The valve on the rear drivers side of my '99 Allure is acting up. If I dump the air to level it when we park and then when I restart the engine and set it to travel mode the valve leaks air out of the exhaust port at a very high rate. If I crawl under and put my finger on the port and hold back the air for about 10 seconds the valve makes a clunk and the air stops. After that all is normal as in leveling when going down the road. Any ideas out there? Thanks.
