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?
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:
- They ship it with radiator hose that breaks down from oil AND collapses under vacuum and heat.
- They suggest mounting it under an existing bolt near the strut tower on the driver’s side, but that location will not allow you to remove the reservoir for dumping.
- I had to drill a new hole nearby their suggested location and buy some hardware to mount it in such a way that I can remove the “tank”, since you have to do that every 500-1000 miles or so.
- There is a wire mesh in the top to help catch particles and blow-by, but some people have reported this mesh breaking down and getting sucked into your engine as well. I have not seen this yet, but removed mine nonetheless just to be safe. I don’t see how removing it will hinder it’s performance.
- UPR claimed to have never heard of any of these issues and didn’t care that I had these problems.
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!
