RULLINEUniversal 350ml Oil Catch Can Tank 0046 Aluminum Polish Baffled Reservoir Black Upgraded Braided Hose

Throw away the hose, it's not vacuum line. They shouldn't include this accessory since it perceptively cheapens the product.I used 5/8 to match up with my system, so the I didn't use the 1/2" fittings, but the fittings are good quality.The catch can is nicely made and I added a drain valve by drilling and tapping the catch cup with a 3/8" npt. Once installed it would be difficult to get the can off. Now I can just flip the lever valve open.Others claim the aluminum will shed shavings after use or cross thread easy. I wouldn't worry about this. It's anodized nicely which provides a hard coat on all the Al. As for cross threading, just be careful, any careless person can cross thread steel too. Some say the dipstick is useless but it actually works, if I see the yellow/brown goop on it (see picture) I know it's time to clean. One person complained that it needed an o-ring seal for the dipstick. This is a low pressure vacuum system, and uses a tappered wedge seal like many water bottle lids use which is completely effective and I prefer since simple is better in this case.The bracket was worthless to me. I can't see it being that useful to any application. I welded together a bracket of my own.In the end it took a while to get everything I needed for the odd ball connectors on my Audi but it's done and is hopefully working. I'll check back after a few thousand miles.Update:After having this on for 20k miles it definitely collects a lot of gunk and and a some oil, my car only uses 3/4qt/10k miles. Most of what it collects is a emulsified oil & fuel mixture. It smells like paint thinner and kerosene. I added 2 stars back since it works so effectively, see picture above. When I poured this mixture into a clear tea bottle it does separate over time with about 70% water and a couple other layers of stuff on top.I found my drain valve became plugged and I need to add a larger valve with a least a 1/4" diameter through hole rather than the small toggle air valve with a 1/8" orifice. Since it wasn't draining properly through the valve, it filled to the top and my car began to smell like gas or exhaust on the inside. If you get this smell, clean your seperator. Once I cleaned it and put it back together the smell went away. I'll be checking this more often like every 3-5k.I think this is must have on the Audi pre 2016 engines that have carbon build up problems on the intake system and valves. I have the 2013 A6 with the 3.0 supercharged V6. It now 58k miles and I've been running this for 20k miles.

I ordered three (3) of these and installed two on both of my cars; one on ny 2012 Prius "v" and another on my 2016 Nissan Versa Note.The quality of the the billet T6061 aluminum components is exceptional. The cup is made from a multistage deep draw process like that used to make oxygen and scuba high pressure tanks. It's wall is thicker than it needs to be. The outside is still precision machined for a near perfect match to the valve body. Having been a machinist in manufacturing processes and an auto mechanic for many years, I can tell quality when I see it. At $36 delivered by Amazon Prime, these oil catch cans are an exceptional bargain.Yes, the vinyl hose in junk. I replaced it with the recommended 3/8 inch gas line hose.The fittings are also high quality CNC "ORB" or (o ring on boss) hydraulic quality fittings. The O rings supplied are undersized for the fittings supplied. I replaced the low quality undersized O rings with Viton ones. There was no O ring on the dipstick, while there is a channel to take one. I placed a correctly sized Viton O ring in the channel, so that it would seal correctly.Instead of the worm drive band clamps, I used OEM quality 5/8 inch constant spring tension hose clamps for the entire installation. The Hillman brand was also purchased on Amazon.com. Since some of the component nipples on the hoses are plastic, worm drive band clamps exert perssure points on plastic that would eventually damage those fittings. That's why constant even tension spring clamps are suppied as OEM equipment,The install on the Prius "v" was fitted with custom made stainless steel strip brackets fashioned to fit the OEM mount in the space left by the removal of the original filter box to install the HPS cold air intake that I purchased last year from Amazon.com.On both installs, I repositioned the OEM PCV hose and connected it with the 5/8 clamps to hone nipples that I custom machine from black PEEK (polyeitheretherketone) plastic. Those who do not have machine tools can use commercially available hose nipples.I would highly recommend this oil catch can to any user.A friend of mine liked the photos of the Prius"v" install so much, that I sent him a prepared set with the correct brackets, hoses and clamps, that he installed it in 30 minutes.

First the bad, some reviews say these things stink coming out of the package. I thought for sure that was an exaggeration. I was wrong. This thing REEKS. Once you get past the smell, the threaded surfaces fit up very well. An O ring needs to be fitted to the dip stick. The hose fittings appear to be straight thread and fit up with the can is good enough. I'll probably use a sealant to be sure that they don't leak. Two sets of hose fittings are included that should cover the vast majority of installs. The inlet filter is actually two parts, so a mesh screen screws into the lid, filter material is added, and then another screen is screwed on. Well done. The hose is crap, the intestines out of a pig would be a better choice. Just leave it in the box and buy good hose, odds are it won't be long enough for your application anyway.Update 4/27/2018 As I suspected, sealing of the fittings is an issue. Replaced o rings with quality o rings and sealing is much better. Mounting can be a real pain. If I was going to do it again, I'd probably use a hose clamp instead of building a bracket.Update 4/7/2018. Took a 150 mile journey this weekend, mixed highway and off roading. I was amazed at how much oil ended up in the can. Blow by on this engine is very minimal but oiling must be excellent. Hose to the intake was dry so it is doing a very good job of separation. I'm using stainless steel scrubbie material for my filter medium. Available at Wally world in the dish section.Update 4/18/2019 This has continued to perform well. If I have one complaint, I wish I'd bought a bigger one. In winter commute driving, it needs emptied about every 600 miles. It's shocking just how much water is condensed inside an engine during a typical Montana winter.
