What do you mean drive it for a while before I bring it in? You mean to get the engine light to come on for the mechanic?An engine can run lean enough to set a code without pinging and rich enough to set a code without smoking. I'd be leery of tearing down a 178,000 mile engine if I wasn't going to completely go through it but I also wouldn't buy a 20 year old used engine unless I was going to rebuild it. If it passed the leakdown test that indicates the rings are sealing but at 178k they've got to be worn. It might be worth a second opinion but drive it for a while before bringing it in for diag and do not plug your code reader into it. We had an autozone 1/4 mile from the dealership and their $29 code readers caused us no end of problems.
And how can a code reader cause problems? You mean the customer came in with false assumptions base on bad reading from crappy code readers? or the code readers messed something up?
