Don’t have a supercharger or turbo so you’re not worried?  Think again!  Neither do I!  Have you checked your throttle-body lately?  This amount of oil blow-by comes out after only 250 miles of driving.  You don’t want this gunk getting sucked back into your intake do you?

After just 250 miles

Nasty.  Make sure when you clean your throttle-body that you only use cleaner that is safe for coated throttle-bodies, or you will eat the finish right off, not good.  For about $100 you can get a nice looking billet oil catchcan.

I went with the UPR Products version.  I’m happy with it, but I have a few complaints and UPR didn’t care nor did they offer a remedy.  I’ll get into that later.

See the tube coming out of your driver’s side valve cover and going into your intake in front of the throttle-body?  Yeah that’s the guilty party.  The vacuum is needed in the valve covers or you lose power, that’s fine.  But you don’t want this junk getting sucked in your car’s lungs with it do you?

You may need one on both sides if you have a turbo system or supercharger.  Just make sure you don’t lose vacuum.  Also, DO NOT just pour this blow-by back into your engine.  It contains vapor and other junk you don’t want to put in your engine.

Now about the UPR catchcan.  Overall I’m happy with it, but here are my main beefs:

Either way, the UPR kit is otherwise well made, just keep in mind that you’ll want to get some nice braided tubing and connectors so the tube doesn’t collapse or break down over time.

Now go stop that blow-by from gunkin up yer junk!
