Take the car out and drive the piss out of it, Lots of high RPM/redline driving. This will do two things, 1)It will ensure the lifters are full and all air is blead out of them and 2)The oil is at full operating temperature. One other thing of note is that the check balls in hydraulic lifters sometimes won't seat properly seat if there is debris in the oil. ensure you are changing the oil at 7500 mile intervals max, BMW's recommended oil change intervals are just plain too long. Keep me up to date on how you make out, I am very interested to see if your engine stops making this noise!

A ticking sound that is coming from the motor is not something that should whimsically be dismissed when your pushing the car to its absolute potential. But now that the car is stock I dont give the slightest shit about it anymore and if it blows it blows and I bring it to the dealer. Last edited by erm324; 09-26-2012 at 12:47 PM.. |

But def keep in mind that all M cars make a lot of valvetrain noise. My e46 m3 used to sound like a sewing machine, and my e90 isn't too quiet either; you need to learn to discern the differences in sounds (i.e. valvetrain noise or something bad). Just enjoy the car! |

Well...12 days in the shop now. The ticking sound was what most of the other people have reported. Main crank and bearings. Can't say I'm real happy, especially being so new.

@RushRuin and Helmsman unfortunately I don't have anything to help you guys. The engine was dismantled to some extent by the dealer and BMW's regional M technician I believe and they found nothing. A few thousand miles later (maybe 8-9k on the ODO) the ticking miraculously disappeared. Totally bizarre. I had the car up to about 50k miles or so before trading it and there were zero engine or other problems.

Welp, after noticing a non rhythmic ticking sound during idle when my car was warm earlier this week, I decided it was not normal and time to jump on the trusted m3post.
After watching the video at the top and reading, I am about ready to head to the dealer and flip out. I have 2013 with 21k miles and I love my M. |

Once the cooler ambient temps hit, I'm sure there will be far fewer "ticking/OMFG/WTF" threads around here.

Posted in another thread but wanted to add it here, as it sounds very similar to OP. I've only had the car for 3 months, about 2000 miles (touch over 50k total miles). I had a PPO performed and the car recently spent a month at the dealer for a warranty-covered fuel system issue. Unfortunately the warranty expired 400 miles ago and noticed this sound. It has been warmer than usual and the oil is at the halfway mark, when I got it it was all the way full. Happens when car is warm after a normal 20-30 minute freeway drive. Don't really want to replace bearings unless I have some indication that that's what's causing this, any input appreciated.

Personally speaking (as a car mechanic of 25yrs), I think the sound in the ops video is a tapping hydraulic cam follower failing to maintain the right gap. This can happen after an oil drain (especially a long one), but normally it would bleed out any air after a few miles or so. I can't explain why this one took so long to sort itself out though! Maybe their was a tiny bit of debris in it's oil feed???
[edit]I LOVE MY M3 - if you ever come back to this forum+thread, can you tell us more as to why that engine was pulled apart? Judging by the photos the bearings are in pretty good shape, bar the slight uneven wear on the main bearings, so I assume it was a preventative/investigative strip down?

Which would sound nothing like the ops video
(I was tempted to revive an older (2014) thread earlier, someone said something that was blatantly inaccurate, but I just resisted temptation ) (PS I also have a white M3, awesome colour for them ) Last edited by Assimilator1; 02-13-2020 at 02:18 PM.. |
