    I bought this Chinese half-liter can from eBay for $14. It does not have an internal diffuser so I'll probably replace it in the future. I reused some hardware to make the bracket from yesterday's Tru-Cool project.

    I had no clue to where the PCV hose was and where it went to so I found some instructions on the internet for a kit for UPR's $109-159 catch can (depending on the options). Word to the wise - before you cut anything just know that the 90-degree adapter on the top of the engine is not as the instructions portray. I sliced it close to the fitting and discovered that I had destroyed the part. What I should have done was cut the rigid plastic tubing out about two inches. As you can see in the photo, I ended up drilling out the fitting and friction fit a piece of the tubing back into it. Also, I used my OTC Master Flaring Kit to make flared ends on the rigid tubing so my 3/8" hose wouldn't slide off. can01.jpg can02.jpg can03.jpg can04.jpg can05.jpg

    This entire project cost about $18 if you account for the six feet or so of 3/8" tubing. I might order this catch can that has a baffle of sorts but is only $23.

    I'd advise against the one with the breather on top since it will be a vacuum leak and cause high and/or erratic idle and an SES light. That one may have a plug option to replace the breather, though. I recently bought this one for my brother's truck (I have a catchcans.com one that I'm happy with). It looks to be a well-designed unit, especially for the price, and the only thing I'd do to it is add a piece of stainless scrubber pad on top of that round silver disc. I did this to mine and it improved it's efficiency. I just wish that Amazon one had a larger capacity. But it's easy enough to drain with the valve. I also wish the inlet and outlet ports were swapped around. They have an identical model with 3 ports that has a second inlet port that I should've gotten. I would screw a plug into the other inlet and then the ports would be oriented in a better position for a cleaner look on our engines.

    Here is an update. I think I’ve driven about 400 miles since I installed the oil can. I drained it and some nasty emulsion came out. I’d guess about three ounces. I was quite surprised that south water lurks in these engines. I need to install a miniature ball valve and drain hose at the bottom of the can.

    The water is condensation formed inside the can
