Other than the possible affects to performance created by the increase in pressure, The next weak link would be the valve cover gaskets.
What other possible affects could there be?

That's the thing. Without knowing the flow rate of the valve, there is no way to know if the result is more, or less, crankcase pressure, or if the intake sees it as a bigger, or smaller, intake leak.

I grew up watching him in the 80's. I would probably still be transfixed by all the amazing experiments again if they would play some re runs.

Did you find your PCV was dirty/clogged defectoive when removing? I often liked to (previously) remove and lightly clean 'em along w/ the breather hoses every other oil change or so in past, maybe I can forego this for a while now?

Though I'll still probably opt to change it (PCV), and the plugs (cuz they seem to "Weld" to the heads if left in longer), air filter (2nd time), brake fluid (at least empty/refill the resoivoir every other oil change to keep clean fluid through the system), clean the TB butterfly area (every other OC) and maybe the Wal-Mart $18 fuel system cleaning at 60K~ before the plugs also...and all the fluids based on the manual severe service interval. Especially since I only put 6K~ miles a year on my vehicles..

Good idea about break fluid change... what is the resoivoir capacity?

I want to buy right size fluid.

I buy 2-3 of the mini bottles and toss any opened ones left , they (plastic bottles of brake fluid) are hydroscopic so not good to keep around, ... even using a turkey baster and suction/refill every 18K miles will help keep the system clean w/ fresh fluid. Good maintenance also for vehicles w/ refillable hydraulic clutch resoviors (JK's are sealed though). Do the same w/ your Power steering fluid too. Follow the manual for proper fluid spec...

Just an FYI, It's my understanding that the clutch cylinder on the JK actually gets its fluid from the brake reservoir. So you are essentially servicing it without even knowing it.

What do you use to take out old fluid?

And you don't need to spend the money on the Deluxe Automatic "Master-Baster".
The regular hand operated baster will do just fine.
