So, changed valve cover gaskets recently. Noticed an undue amount of oil in the pcv vac lines coming off the valve covers, which seemed odd to me. New pcv 4000-5000 miles ago; it still seemed to be working fine.
Just for poops and laughs, tried an experiment.
Ordered a $30 amazon catch can with a filter. Took the vac line off the driver's side valve cover, and installed the filter from the kit on the right angle elbow coming off the cover. Capped the breather tube port on the throttle body.
Installed catch can under the throttle cable bracket. Figured out that the lightweight filter foam that comes in 100mL antibody/serum shipping boxes is the exact same size as the "filter" canister on the "out" side of the Amazon can. Cut off a slice and stuck it in. Fluffed up a stainless steel pot scrubber and put it in the body of the can. Plumbed can backwards so that the pcv went into the "out" side of the can, and the "in" side attached back to the pcv port in the plenum. Hooked up backwards so that the engine vacuum would draw through the filter on the driver's side via the pcv, gasses would flow into the stainless media, then foam filter (hopefully blocking stainless steel shrapnel from entering the throttle body), then exit the can into the pcv port in the plenum.
My truck has always ping-ed under strain on hills, especially the ones in North Pittsburgh.
I DID NOT clean anything. Just hooked up the can. Went for a drive. ZERO ping. I mean zero. Nada. Zip. Zilch. Idle usually was at 1000-1100 when the engine was at temperature. Now sits at 800-900, and all hesitation and roughness is gone. Exhaust smells noticeably different. Noticeable new "pep" when pulling out from a stop. Checked the can after 50-ish miles. The media smells like a fraternity couch was thrown into a volcano, and is oily.
Anyone else try this? It seems my 2.9 was extremely sensitive to oil vapors/pcv crap/the factory dual vacuum setup that didn't make sense to me.
Feel free to criticize.

I'll bet $1 at least one person will respond with, "put a 4.0 in it"
