Thanks but I went ahead and ordered a pair of aftermarket ones for $170 last night. The dealer wanted about $565 with a discount for just the intake one. I found that the spring had worn into the outside of the cover on the old one plus there appeared to be some wear on the inside as well. Taking one apart was kind of nice way to see how they work. I think the groves the spring wore into the outside stopped the cam from springing back to normal position when the oil pressure stopped.
