Visually, it looks just like the older engines. They have re-designed
the intake gasket, both the side gaskets (new design has double row
of rubber that goes around the coolant ports) and they now include
an actual gasket at the front and rear of the block instead of using
RTV. Intakes look different, and there are some differences in
the exhaust system.
I keep hoping the General will fix the underlying design flaw that
lead to the intake gasket debacle. Maybe an increased fastener count
or adopting a 'dry' intake manifold design.
Wishful thinking, I guess.
Still like the engines, just wish some of the 'irritants' would be
properly addressed. I prefer a 60 degree design for a v6 (balance is
everything!!) The 3.8 with its split crankpins, balance shafts, UGH!
I suppose so, unless you have one that is in a high mielage vehicle.
Course it doesn't really matter...GM won't do anything about it now -
last time I talked to a local tech, the "tick time" was up to 15 or 20
