Great video. Btw I appreciate you removing the engine cover so that excess heat can be dissipated easily whenever the engine is running & after it is shut off. All turbo engines need their plastic covers removed in my opinion.
So today I was at auto polishing center to get a wash. The line was extra long today, I waited about 45 mins before the car was rolled into the bay for its hand wash. The whole time I had been idling. Boy was that a mistake. As soon as it went in a loud whistling sound was coming from the car and then massive amounts of white smoke was being released from my exhaust that smelled like gas and oil. Turned the car off immediately. Then turned it back on a couple mins later to move it out the bay and same thing started smoking. Turned it off again popped the hood no smoke from the bay no leaks and everything was sealed. Immediately I thought it was my turbo and could possibly be something catastrophic. But then again no CEl Light and I drive reports system ok. Decided to let it sit for 30 mins. Started again and no smoke idle was fine. Drove it home 25 mins away no misfires drove like nothing ever happened obviously I drove conservatively and put it in the garage. After reading threads and forums I came across this video and hey man, thank you because I can sleep tonight lol. Gonna get this replaced tm.
I think I might be the only person who has been bold enough to seafoam my b58 and s58 straight through the throttle body and into the intake valves as many times as I have . And I can promise you it works , you just have to do it the right way.. and make sure the car is at a certain elevation so it can hit every cylinder . My tail pipes don’t even get dirty anymore when i run my finger on them after a hard drive
Positive pressure in the crank case would not push up against a downstroke piston unless you have a one cylinder engine. With multi-cylinder engines, every downstroke is matched by an upstroke for an opposing cylinder, so overall volume (and thus pressure) should not fluctuate over time. Another way of looking at it is that any upstroke piston is helped with the exact same force that is resisting its opposing downstroke piston. It's adding equal weight to both sides of a teeter totter. Positive crankcase pressure (PCV) can cause oil leaks and engine oil sludge though
Positive Crankcase pressure is always pushing up on the bottom of pistons whether they are going up or down. It creates resistance when pistons are on the downward stroke.
Great video Kevin, as always! Cant get more didatic than this! I have been wasting my thoughts on this subject recently. Debating whether to run a catch can or not. I really like the catch can idea, but dislikes the added maintenance item to keep track of and also I am very concerned about adding a container of likely flamable content on top of a hot turbo area, with extra components such as hoses and fittings that could also be another point of failure. I also dislike that, in most cases, seems like I would have get rid of my engine cover. Last week, during my regular oil change, I wanted to know how my PCV system is doing, so I decided to pull the breather hose out of the valve cover that goes into the air intake, to look for some gunk in there. After 5 min trying to pull that little shit out, I gave up and went straight to the charge pipe xD. Pulled the charge pipe and was impressed by how CLEAN it was, not a single drop of anything, pefectly dry, including the throtle body. I could eat on eat. So that gave me some peace of mind and makes me believe the PCV system is working as it should, even after running on Stage 2+ for almost a year/20 k km on both normal / spirited driving conditions, including a few trackdays in the count. A bit off, may I suggest topic for another video? Oiling capability in our B58 under high G! This is a topic I catch me reading up late at on night on the bed every now and then xD I have a number of logs from my trackdays this year that shows no oil pressure losses, but Im on Michelin PSS, and im pulling like ~1,2G max when cornering on a fairly long sweep. I wanted to go to some proper track tires, but this is something that bugs me a bit, so for the time being, grease my tires will be at the end of the stint
So would you recommend a catch can or a vent to atmosphere solution. I saw a video basically saying you wanted to make it bulletproof, doing a vent to atmosphere solution, how do you prevent any type of leaks to the valve cover?
You think you can make a video making a list of maintenance things to do to the 340i/b58. I bought my 2016 340i 2 years ago with 62,000 miles and I’ve done pretty much the basic maintenance and I’ve recently hit 100k. I just want to make sure I keep this car as clean and reliable and happy as I can. Please and thank you
I bought 6 kits of diaphragms for me or for my homies. I usually idle for long periods of time in my car due to my job, and the heat is definitely nothing to play with so I gotta keep AC on full blast. Having this extra few kits keeps a peace in mind cause I can change them on the go.
Thank you Kern for this video. I have been on the fence about whether or not to purchase a BMW with the B58. I have 1 question, the photos of the intake valves on your B58, were they taken prior to or after you installed the PCV delete? Thanks for the informative and helpful content.
You know maybe about a month ago I just received a letter from b. M. W north america on a warranty extension for ten years or a hundred and fifty thousand miles on that p c v system
My 440 has been smoking and whistling still even after I just changed the diaphragm. I’m thinking it could be the either the valve cover itself or the o2 sensor. It also struggles and startles after refueling. Please help 😅
What year is yours ? Mine did the same thing and I fixed but at first It still did same symptoms and come to find out, I didn’t install diaphragm correctly, so make sure you correctly seal it and it should be back to normal, if not then possible valve cover but I doubt it.
I have a BB kit and it doesnt use the evap fuel line. Do I need to put a filter on it? Do you happen to know the fitting for it? I dont want to delete it.
I have an issue whenever I accelerated up to 4k rpm To redline. Ill hear a whistle. Happen whenever I hit boost, I drove up the rpm without hitting boost. Whistle isn’t there. Just changed the PCV but sound there. No check engine light.
Running a BigBoost G35-1050 with built trans, motor, and pretty much all supporting mods pushing around 33-36 psi. Ordered the V1 Ross catch can and delete instead of the V2 on accident. I was wondering if the V1 would suffice or not. I also have oil residue in the intake right now without the catch can so one is definitely needed.
Hi Kevin, My car has already 55,000 miles, it is B58 Gen1 and tuned with MHD Stage 1, it does not consume any oil between the change intervals I do 5,000 -6,000 miles... It is my daily driver, I do per month approximately only 1,000 miles and I do not usually push it to the maximum constantly, only sometimes when the highway allows me to do so. This engine does not consume any oil? Or only in some scenarios? Greetings from Spain! 👋🏻😁
I had a 18 F32 440xi with stage 1 93 from BMS traded it last week for a new G42 M240xi. The 440 had 44,500 miles on the clock and it never burnt oil. I did have a issue with coolant but changing the cap on the main tank fixed it.
I check the level when I bought the car and I check the level between the first oil change and same bro. Level was the same. Crazy how efficient these cars are!
Oil consumption on the B58 is something that intrigued me a bit. Because my car has never shown any oil consumption (level sensor oils reads MAX level, no excessive soot in the exhaust tips), I decided to experiment. Last weekend I measured how much oil went out. I drained it hot, as per service instructions and let it drip until it was dropping. I managed to get ~6L out of 6,5L I put in. So there has been some slight consumption in between 7k km of normal daily driving, spirited, occasional race and 3 track days. Oil in question is Motul 8100 xcess gen2 5w40. After replacing the oil, I measured on ground level, downhill and uphills … same MAX reading in every occasion. That bugged me so I bought a new oil level sensor which will be replaced in my next oil change, likely end of the year prior to storage for winter time. Either my level sensor is faulty or it is not accurate enough.
You'll never be able to drain all the oil. There's oil in the galleys of your cylinder head, your turbo, and between all of the components. Even if you remove your oil pan and leave your engine overnight, you'll wake up to a puddle of oil underneath.
Im at 57k miles looking to keep stock turbo as long as possible as I don’t care to go fast and my car is bagged, currently only have tu pump and downpipe but im looking into pcv kit by Ross. Kern, let’s say you had my car and looking to only go fbo let’s say within 2 years what kind of maintenance mods would you do??
If you have a PCV delete there's not much else. Just keep up with regular maintenance and run logs/diagnostics from time to time to make sure it's all healthy.

That would only be true if the pressure had nowhere to go. In the case of multiple cylinders it has other places to escape.@@kern417

Not in my experience. If you have oil consumption then sometimes thicker oil reduces it.
