The experiment to determine if a catch can can reduce the oil consumption on the M54 engine is over. My results are:
394 miles: no oil consumption at all
NOTE: I have uninstalled the catch can that I installed in this video. I was getting an occasional problem where I could smell oil fumes and it was honestly very annoying and unpleasant. Please do not purchase the oil catch can I used in this video. Find a better one that doesn’t have the oil level indicator on the side and thus will be better sealed to vacuum. Even then, take great care to completely seal up every part of that can.
There is an alternative to running a catch can if you live in a climate where condensation and clogging of the OEM CCV system is not a problem. Please see this video:
Here is the parts list for the Oil Catch Can project:

Any leads on after installing this, having misfire and SES light but no limp mode EML light, you can just feel it misfiring at certain throttle positions.
Greetings.Great video! I just wonder, I have seen a few setups without PCV valve. What is the worse that can happen if we do the same setup without the PCV valve?
So you switch the pcv to the valve cover 3/4 hose, but the switched it back again to the 5/8 tube on the intake with the new pcv?
A little confusing with all the changes
28:40 Those "slip in" connectors are not siutable for vaccume. they holod prerssure really well. They don't have standard orings. U need to use screwed connector with nut for this pipe, instead of "slip on" type.
Thanks your video.
I have some questions
My E39 is M54 525i engine
Are there any disadvantage to delete original ccv systems after long time test?
For example: oil consumption or air leak problem
Will OBD detect error code after delete ccv systems?
Great vid!! Is this the same with the m56 sulev e46 325i? I’m pretty sure my ccv system failed as I drove 3 hours and after parking up and restarting the car I had the most insane misfire I’ve ever felt. Plugs and coils and common vacuum leaks previously sorted. Do you recommend a catch can on the m56? Let me know thanks!
I know this is a long shot cause this is 5 years old, but what about the vacuum likes that come from the fuel rail? Do I just need to plug it off?
HERE is a much better catch can that doesnt have that oil level indicator. This one has a threaded dipstick instead… https://www.amazon.com/gp/product/B076BKV7JF/ref=as_li_tl?ie=UTF8&tag=scottykilmerc-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B076BKV7JF&linkId=2633bfde063561407fe85724ff492bf8
hey man awesome videos great job
is there any plugs to the stock ccv that will throw a code after deleting system ?
or does computer just forget about it ? per say
Hello 50'sKid, I just want to thank you for all your time and effort spent on making these repair videos on the BMW E46. I have being running BMW's for a little while now and I really enjoy the ride and power available, also I think the car looks cool. I live in New Zealand and the second hand cars here just don't seem to get any rust on them so they keep very well. Only problem is if you damage an older car here the insurance companies tend not to want to repair them. So now I'm one my second 2001 325i Sedan with 138,000 km on it and yes it's right hand drive. I'm a Outboard motor mechanic in my first trade so wrenching is my favorite pass time now. I'm a 50's Kid also and I feel a comradeship with you. Your my savior and best bud when it's time to work on the car. Keep up the good work friend.
Oil catch can is a nasty name for a part I would want to install on my M54 BMW. I would suggest looking at the German Auto Solutions upgrade. It looks very professional, opposite to an eBay product.
Great hard work though!
50s kid is one of the few people who understands that PCV valve is still needed if you use oil catch can. Basically you rebuild the original M52 PCV system with aftermarket components. Without PCV valve the high vacuum (when car is idling) will suck a lot of oil fumes from the crank case. This is the purpose of PCV it should be only open when throttle body is open.
help help help
today I was out for a test drive and much oil comes out of the exhaust … I installed a PCV ( PTC 345 ) but i was wondered these is a metall and its clicking when the PCV Valve is chacked, should the is a sping inside?
I open my catch and see there is no vaccum the direction of the PCV is correct
Also I wonder the catch on my last 30 KM around 20 Miles testdrive have catched much water // I must say I drive the car most time in short distance
next step the check the valve or installation without a pcv valve // or close the intake ports and output from catch to the air filter
Not going to work. The check valve to the dipstick is spring loaded , the can wont drain. If you take it out it will suck from the pan
Is he planning to drain gunk from that catch can back into the oil pan?
Did this and now oil is shooting out of my o2 sensor..
Update on catch can systems?
HI 50's Kid, just asking hows the vehicle oil consumption rates at about 1000 miles and engine oil smell or smoke inside the vehicle as what you mentioned in the video. I'd like to know what is your final assessment on the oil catch can project and it's latest part update. I have an X5 with M54 engine and interested with your modification, as usual and normal oil consumption issue.
Is it also a good idea for diesel?
you’re the best dude !!! you got solution for it all shout out to you
