I purchased this Suburban new in 1999.
At 21,000 miles it began to use oil.
The number 5 cylinder valve guide had
to be replaced. At 55,000 miles the
right side head gasket began to leak
antifreeze and had to replace gasket.
However, I will say this is the best
highway vehicle built. It rides better
than the best cars. The 5.7 L (350) is
too small for this size of a vehicle
and that is a downer. The 4wd works
like a champ in mud and slick roads.
The auto on the fly is great. This
will be the last "beast" I will own as
gas goes up in price.
