• How often should valve adj be done on 1990 535i. I had head gasket replaced about 25K miles ago. Is that usually done when head gasket is replaced?

• Are there symptoms that valve adj needs to be done?

• How much can I expect to pay a good indy shop to do valve adj??

• Car is running great...should I worry? I've had car for about last 60K miles. Other than head gasket, nothing major done.

Thanks guys!
