Thanks axgordon,

You convinced me, I am taking the thing apart and go to Home Depot today to get all the odds and ends.

QUESTION: I don't plan to use the Duralast PCV Valve (which is basically one-way valve with the spring inside to allow air to be sucked in at certain vacuum value) simply b/c I am afraid if the PCV is ever stucked closed, the crank case pressure will be very high and some seals will be blown, with the RMS being the worst to repair.

So, who uses Duralast PCV and who does not?
