Bmw N52 engine rough idle. Non return valves cleaned!!!

[@WarpDriveM]

Update on the video! after a few days the rough idle was back on cold start only and I've found out that my CCV valve was broken aswell! See that video here: kzbin.info/www/bejne/rWHWeHeVea1qecU Installing a stage 3 intake here: kzbin.info/www/bejne/iZLPh6aibZ2ebKc

Brooooo. You saved me thousands, the repair shop quoted me on some bullshit replacement.... these are the things ive done my self trying to solve the misfires, i replaced ignition coils,vanos solenoid,crank shaft sensor,new oil, new sparkplug, i even got the valve cover gasket replaced... and it sat there for 4 years... finally after watching this i did it my self this morning.. removing the front right wheel and removing the wheel well makes it a easier task! The bottom one had some particles, but the top nonreturn valve was filthy!!! I cant thank you enough!!!

I wonder how many people have spent $$$$s replacing the VANOS solenoids but never checking these... probably a lot! Makes me wonder if you even need to change the solenoids either... Maybe just remove and clean them like this and keep the engine oil good and clean, should avoid all the expensive VANOS issues BMW engines are so famous/infamous for!

[@makeshiftpatriot]

One of the best videos I’ve seen for fixing rough idle issues.

[@markbutler9291]

Rough idle can be caused by blocked engine crankcase breathers. The breather filters are built into the valve cover which will need to be renewed if this is the problem. When the engine is running remove the oil filler cap and remove it, if the cap is hard to remove or you hear any 'sucking' noise as you remove it then you have a breather problem.

[@doggboy6688]

Were is the oil filter cap 528i 2008

[@Crone85]

Isn't that only on N53? Believe N52 has the CCV attached to the inlet manifold

The CPV valve is built into the valve cover! Rock Auto LEAST EXPENSIVE by far!!

[@thecommenter7201]

I removed the oil filler cap but it is not sucking air at all.

[@islamilluminatedd]

Thanks for covering this. My rough idle is not as severe as yours and does it momentarily on cold start ups. I already replaced my valve cover assembly, eccentric shaft sensor, ignition coils, spark plugs, vanos solenoids, cleaned MAF sensor, and changed oil to 5w30 instead of 5w40. I will be ordering new non return valves to replace them, regardless if they turn out to be clogged or not. Update: I replaced my non return valves today. I noticed both the motor and trans. were more smooth, so far. I only get the rough idle after leaving my car alone overnight, so I am gonna have to wait and check how the idle will be the next day after a cold start.

If rough idle it's correlated with smoke when you floor it, check the O2 sensors, this was the culprit on my N52. Changed everything, vanos solenoids, coils, spark plugs, etc. Problem was Bank 1 pre-cat O2 sensor, NO check engine and NO fault codes...

This is why I love KZbin, just search and u can find. Edit Saved a lot also on doing my own starter, that went out again. First time paid over 1200 bucks at a dealership.

Change your spark plugs to the new 4 electrodes on them, BMW changed the spark plugs without telling customers to fix the idle problem The new plugs are available at BMW to replace the single electrode one.. The bmw & Mini dr on youtube has just given out the info recently..

You don't have to believe everything from the net.

My 2007 x3 also chugs but has a really loud high pitcged squeal and does it all the time. Everything i found on it is that i need to replace the pcv vavle... which just so happens to supposedly be molded to the valve cover.. atleast from what ive been able to find out about it.. its creating a ton of suction and if i take oil fill cap off it stops squealing but will still chug just not as bad.. took it to bmw dealership and they said my valve cover is cracked.. didnt say where just that it would cost 2500 dollars.. there is no oil leaking tho. Which my dad a mechanic of u.s. domestic vehicle of 20+ yrs says there would be oil leaking out of a crack if there was one... there is some sensor on the top front of my engine that has had caulk rubbed all over the case and there was a bit of oil in the plug part of same sensor.. cant find what the sensor is to replace it tho.. for all i know that could be the thing i need to fix..
