Findings: sludge buildup after 50to60 thousand miles. source seems to be
under the air intake manafold. I have heard there is a problem with cracks
developing in the air intake manafold allowing infusion of air,ie increase
temps. then flakes of carbon particles. This stops up the oil pump. Is
there any validity to this? How do you check an air intake manafold for
cracks?

Nope...not really, altho there is a problem with the early models sucking
out the intake gaskets....altho, that leads to oil comsumption, not sludge.
Sludge is due to lack of oil changes, or a clogged PCV system.
