I just recently started driving my 90 SC and ive been gettin out in much more. but it has a damn valve tap just cruising around town and its annoying as hell. Its almost the same as my 91 LX with the 3.8 that i sold a while back. Is this goin to hurt my car in the long run? cause i was thinking about getting it fixed. and is this a common problem with the 3.8s?
