AC PCV Tester instructions?

[BusterofKnuckles]

I recently picked up a very nice AC Positive Crankcase Ventilation Tester (PCV Valve). Would anyone happen to have a nice, clean copy or scan of the instruction sheet? Thanks.

1950s lore, but if it rattles when you shake it, it is good.

Agree. As long as it will take you hooking up that thing, you could have shook the PCV to see if it’s stuck or not. Loose= good. Stuck=bad. That simple

If that's vintage, it's in perfect shape. Nice find.
I'm sure someone here has the Google chops to find the manual for you.

In the meantime, here's some directions: Remove the pcv valve from the engine and blow into it from each direction. Air should flow in one direction only. Then wipe the oil off your lips, spit on the floor, and replace it anyway "just to be safe".

You forgot running and entire can of brake clean through it, after blowing through of course.

Here's a partial shot, off of ebay.

Just replace the PCV valve. The time needed to test it with that tool is more expensive than the valve itself.

I didn't buy it to test PCV valves. I turned wrenches for nearly 30 years and have a meager GM collection, among other brands and makers. Items as pretty as this one are sometimes irresistible to me, especially at a very fair price. This one, however, is missing the instructions, which I always try to acquire for the tools I have, where applicable.

My 2 cents worth to those who offered advice on testing PCV valves: shaking isn't much of a test. I've replaced MANY bad valves that passed the shake test.

If I remember correctly you have a gm product with a 1.4L engine right? If so and you get bored google 1.4 pcv valve replacement. Cliff notes, it involves replacing your valve cover and intake manifold.

Yes, I do, and it's under warranty, so I won't be replacing it at all. The power train warranty is five years, and I drive it less than 3000 miles a year. No worries.

That's all fine and dandy and you mentioned that in the post I remember. Was just pointing out that a pcv isnt what it was 40 years ago so when you comment to just replace it I was letting you know your engine doesnt have a traditional pcv and while that tester isnt for modern day engines, modern day engines arent as easy as swapping out a 5 dollar generic pcv. And gave the example of your own engine for you to see. Glad your 1.4 is under warranty because it's one of the worst engines I've ran into and I've made a good deal of money fixing all the issues on them.
