Does anyone have a feel as to how prevelant these failures are on the 3800
II engine due to intake manifold gasket problems and the EGR stovepipe and
plenum deterioration? GM must have manufactured millions of these engines
over the years. Are all of them going to fail or is it just a very small
percentage that we hear about on the internet? Would be interesting to know
the true story about how many are really failing versus how many run for
miles without a problem. Can anyone shed some light on this?
