Can't agree with that. Ran a couple of my Vettes pretty hard at the track (see sig). They always came back for more without complaint or making these little girlie sounds. I would never dare go there with this car.

If you tracked a BMW, even with this discussed ticking, it would not be making any weird or "girlie" sounds. Most of those complaining of the ticking are afflicted with it during cold starts...goes away when warmed up. These engines, ticking or not, love to be driven! BMWs engines are awesome, I don't care what anybody says. Damn reliable from my personal experience. I won't own anything else. I love BMW!

Other reasons not to track this car. The current 3 series is about 800 pounds too heavy. Mine is also an automatic, so forget it. Tried to find a manual, but that is a long story for another time. The new parts, HVA & cylinder head, have been changed, so basically says the engineers agreed a fix was needed, right? Not trying to slam here, but I expect BMW, with its reputation, to get it right the first time. In fairness, early LS1 Corvettes weren't immune either, they had some issues with piston rings to work through.

Still reading through the old posts, couple references to it not being harmful. My dealer also said the car could be driven while the parts were being ordered (but I left it there instead).
Found other posts showing abnormal wear to various parts in the cylinder head. The first post in this thread was in 2006. I'm wondering why we are still reading about this? The replacements parts have a different design, so why weren't they introduced as standard production? I'll keep reading.

I actually told my service advisor that it sounded like a diesel when it was making the tapping.

In my case, the car is only used for short, in-town, errands. Which apparently creates a low rpm oiling issue in the cylinder head.

I've owned several American cars prior to this BMW and I've spent more time in the dealer for little items than I ever did with my LS1 Firebird Formula, Camaro Z28 (that was a 408ci with 150hp N20 wet kit), and my C5 Z06 that was a also built and used a lot for track duty as well as daily driving. Both the Z28 and Z06 were highly modified cars that rarely had any issues, the Formula was stock except for cat-back and the only issue was a window motor. BMW builds a very good car thats comfortable, and yet fun to drive. However, this car has been more maintenance intensive then any previous car I've owned. I've been into the dealer for HPFP, ignition key issues, steering wheel lock issues, reprogramming to cure other electrical bugs, addition of oil cooler, oil filter adapter leak, transmission shift seal leak, and then just regular maintenance items (brakes, oil, tire rotation). So to say that BMW are more reliable cars, I feel is just plain wrong. Tighter more stringent build tolerances, for the most part yes. Last edited by Brad335d; 02-13-2010 at 03:52 PM.. |

Summary ?
Just went through the thread stack. For anyone just jumping to the end, trying to summarize here, it seems to be a low RPM oiling issue with the N52 engine, short errands aggravate the situation. The ultimate fix seems to be a new cylinder head with a check valve that ensures proper oil pressure is maintained in the cylinder head. Unfortunately, SIB still instructs the dealer to change the exhaust-side hydraulic valve actuators first. So, it means you will make at least two trips to the dealer before it gets done right.
Cylinder head replacement was almost always a permanent fix, but there are a couple posts by people that continued to have problems. Some early posts showing scored parts, due to lack of oiling, so I would question any comments indicating this is just a cosmetic fix. Based on the expense, I'd have trouble believing BMW is authorizing the repairs based just on cosmetics. The latest SIB, quoted below, confirms which cylinder heads were bad and based on the date, does look like early 2009 builds (guess on my part, don't have actual production dates) used old parts before the new parts were finally incorporated into production. Keep that in mind if you are looking at a CPO. It's approximately a $7.5k fix out of warranty. Page 49, post # 1058 Quote:

I'm cross linking for future reference. Is there a break in period or procedure to follow after a lefter replacement?

So both the 328 and 335 have issues.....I mean I thought $6800 was a lot for 335 turbos, but someone just said the fix on the 328 head is $7500 out of warranty. That's pretty crazy....
I did get a X3 loaner that really sounded like a diesel when it was cold... |

you could try to talk to them, say the problem has been well documented and its been happening since before your warranty went out. Just tell um you went to a different dealership and they kept saying they couldn't replicate the noise and you felt it was a BS cop out. Raise a little stink and they might take care of it for you.
