Thumbs up Cleaning the PCV System

You can do the PCV your self.

Get a can of spray carb cleaner from wally world or parts house, 99 cent. Remove the metal tube and rubber hoses. Spray clean the tube. Spray some cleaner into the throttle body.

Use some new rubber hose (3) if needed. Toyota wants too much. You can use fuel line, or A/C hose (from parts store) that fits.

Heater hose will eventually (sooner than you'd like) soften up, as it is not for fuel/oil vapor.

Before re-installing, place one end onto the throttlebody, place finger over one open hole, then blow into the tube to make sure the passage is open. If it does not blow easily, spray some more cleaner, then repeat the test.

Now replace tube/hose assy back into position. Start car. It will probably stumble a bit from the carb spray, so rev it up a few times.

What about the PCV passages in the cam covers? When I had mine off for the 2nd time during my head gasket replacement you should have seen the amount of sludge in there. I actually had to scrape it out with a screwdriver. Serious restriction.

If you have over 100k miles I highly recommend removing the cam covers and cleaning out the PCV passages in them also.
