Knocking noise in engine 5.3 GMC 2013
My truck only has 20,000 miles on it and started knocking at 19,000 miles
took it to the dealer and they stated it was normal characteristics of the
motor. i was a mechanic back in the 70 s and rebuilt motors before. I know
a rod knock or maybe piston slap when I hear it. It comes from from the oil
pan and then on top by the passenger side. It comes and goes and does
not do it all the time. I have a 5 year 100,000 mile warranty on it but seen
as they do not want to commit to something is wrong where do I go from
hear before my 5 years is up. It is a lower mileage than anyone having this
problem.
