Well I talked with the guys at Star Motors and took their advice and am replacing all four valuves and all four air bags. I would appreciate any comments in how to undertake this task, I may have a mechanic do the work but I have spent a ton on this car would like to save some money. How many hours should be allowed for this job if I get a tech to do it? There is lots of stuff with these valuves, bags are hard to get to. Any information would be appreciated. This is a very nice car I hope to post pictures when I am finished. Thanks.
