1990 C4 Valve Adjustments
I had my car fitted with shocks and springs about 2000 miles back. Quite pleased with the outcome. I asked the shop to check if I needed valve adjustments at 68k miles, bought the car at 58K in 2006. They said the valves sounded fine and I agreed. What are the subtle signs of a valve adjustment short of the car running rough. I'm not hearing any ticking so I assume everything is okay and the car runs great cruising and downshifting. Thanks

Thanks MakMov, I'm good on both counts. Hate to fix anything if it ain't broke just because the manual says so. I'm sure if i tracked it, that would be a diferent story.

Ticking can tell you that the valves need to be adjusted. If a valve is too tight however, there will be no indication. This is more of a problem, because of the possibility of burning a valve. An adjustment/check every 15K is recommended.
