The secret is that tolerances were ran "tight" during the manufacturering process and every motor was "hot tested" before being shipped. That way if there was a problem it was caught before it left the factory.
Yea they are great engines. Only thing to go wrong with mine since I got it 55,000 miles ago was the lower coolent intake gasket. Everything else is just regular maintenance or small, like this IAC.
Speaking of that I'm looking around and not finding a place to buy the part. I've looked on Napa's website and can't find anything relating to intake. Maybe I'm blind, but if someone finds a site, could you post it.
Thanks.
