to get all the residue out?
this one was nasty.
drained about 3 gallons of snot out.
pulled covers and washed heads and valley with a brush and diesel.
poured a gallon of diesel thru just before i set the intake too.
did a 50 mile change and have about 300 miles on the current oil.
slight hazy look to the oil.
 
Have you determined that the intake gasket was the real problem?? I find Coolant usually dribbles out of the engine on the side of the block rather than going into the oil.

Headgaskets are not usually the case in those v8 vortecs.
 
i was definatly the intake gaskets.
they crumbled around the restrictor plates at the rear.
burned out around the egr crossover too.on both sides.
 
I would definitely change the oil if it looks even SLIGHTLY odd. Oil is cheap... engines ain't.
 
just did it again.
was just looking for someone who had to purge one of these engines after such a failure.
agree oil is cheap enough to change if there is any doubt whatsoever.
