Yea, not too bad.
BUT I would never go 50,000 miles before checking/replacing the PCV.
I clean them around every 5-10k miles, nad if they don't rattle freely, I replace them.
I'm with you...but plenty of vehicles have them buried now and use the "life" moniker. As in 100k or under I'll sell it and it's some other dude's problem when it fails. I love the 95 Camry in my sig; I change the PCV every Fall. Cost is less than $3 and it takes as long to open the hood as it does to change it out.
Mean to add: Thanks for the link. Good read.
It seems like if you removed your PCV valve, your engine would run like it had a vacuum leak. If you have a fixed orifice tube somewhere in the PCV system, that might not be a problem.
Also, giving the PCV the shake test is a huge problem in some cases. On very old cars, the PCV grommet becomes rock hard and stuck to the engine, and the plastic PCV valve would easily shatter.
All the idea about changing PCV valves out really doesn't mean much on most late model GM engines. My 2013 5.3L doesn't have a PCV valve. Only a port at rear of driver's side valve cover. Like Indydriver, I put a catch can in the PCV line. In 12,000 miles, it captured enough to fill a 16 oz water bottle.
