Cooler weather and ticking engine woes...
Hey guys, temperatures dropped about 25 degrees around here aaannnnddd my ticking begins. I bought my car CPO 4/2011, lifters were changed 3 months before I bought it. In the summer there's absolutely no tick, as soon as cooler weather comes around it begins ticking. I just don't want to go back and get more stuff done, I have NO faith in dealerships. They've done the dumbest stuff to me.
Any of you guys just living with the problem? |

I get it everytime I don't let my car warm up, but easy way to get rid of it as a temporary fix is just drive it till your car is at operating temperature.
I haven't had it come back for awhile now, so I just learn to live with it. |

N52 engine is known to have a clicking noise when cold due to bad engineering. I have an 08 328i with only 55K miles and it does it, even when the engine is warm, sounds like a freaking Chevy. But I notice everything I change out the oil, it stops. I used to change my oil at 8K miles, and it seems like the older the oil, the louder the noise. So l have been changing my oil every 5K miles now. Next time pay attention after an oil change, you will see the ticking noise will be gone.

They don't replace the heads anymore for this problem - they do the lifters and followers only...
And your engine has to have been made before a certain date - they check by looking at serial #'s on the engine. My car does it only when it's very cold, I took it in, and they would do nothing, as they stated my serial #'s show that I already have the most updated parts

My car did this when I first got it... cpo at 25K miles, I now have 55K and it doesn't do it anymore. It stopped when I started using lubro-moly oil additive. The stuff with the molybdenum additive, a tried and true friction reducer.

Replacing the lifters & followers works most of the time, yet some state that the ticking eventually comes back

The idea behind the lubro-moly is that it builds a layer of slippery molybdenum on all internal parts, including the upper valve train. So even the upper parts of the engine have lubrication in those critical few seconds at cold starts before the oil reaches up there. I don't doubt there may be an issue with the size of some oil galleries that prevent good flow till the oil thins, all I know is that for me I was able to severely reduce the knock to what I would call normal for any car by using this oil additive.

Just deal with it. I've had this fixed under warranty multiple times and it always came back.

They stated that NO, the instructions don't call for replacement of the head anymore - just replace the lifters & followers in one visit and that's it... Frankly, I really don't want service tech's tearing my engine apart to replace the head just to get rid of an annoying noise at only very cold temps anyway. My car only did it once or twice upon initial startup when it was 16 deg out. And it was not covered - the serial #'s on my engine showed it had the most updated parts available. So just goes to show you that even with the updated parts you will get the ticking from time to time.

I ran 10w-30 Castrol Full Synthetic in mine, and the dealer suggested trying 5w-30 to see if that would help the ticking. I was experiencing a lot of ticking about two months ago (probably the cold), so I went ahead and did an oil change with the 5w-30 and haven't had an issue since. I will occasionally hear a little bit right at start up, but it disappears within 2 seconds. The tech at the dealer did tell me that the lifter tick you hear is not harming the vehicle in any way. Not sure about how accurate that is. Nevertheless, the ticking is enough to drive you nuts, damage or no damage. |

Oh yea, I don't care anymore either. This is actually an old thread someone revived. I'm over the ticking. It happens at times in the cold, but whatever. |

It's also worth noting that the oil BMW uses in Germany, and the oil the engine was designed with, is 0W30. Not the 5W30 that BMW uses in North America (due to the high sulfur gas we have here.) Last edited by AlanAZ; 03-26-2013 at 08:27 PM.. |

Thats odd, because i just took my car in and got the lifters and rockers replaced and they told me that if the ticking noise does come back to bring the car back to them and they will replace the head.
