Video? Yes! This is exactly how mind sounded pre-cylinder head replacement (which was successful by the way).
(This video shows a 5-series engine, but this ticking sound was identical to mine.)

MrDummy, does yours sound like the video I posted where there is a *distinct* very loud tick mixed in with the *normal* ticks? Or is yours more like all the ticks sound about the same? (The latter is for sure normal).

^^ It sounds like all the same and it goes WITH the RPMs.
But sometimes even when it is warmed up and full of oil with my window down I can hear the slightest ticking noise. But maybe thats due to the overhead design? Thanks

In the video above, you can hear a distinct, every sixth fire, loud tick amongst the normal ticking. That particular issue is fixed with the new head (or HVA fix these days).

I remember reading that on the double VANOS engines the EGR is controlled internally through valve control. However help me to understand how this happens. I am not quite sure how this exactly works. I can think that maybe near the end of the exhaust cycle the exhaust valves are closed at different positions many degrees before top dead center which retains varying amounts of exhaust in the combustion chamber which will be re-burnt on the next cycle. More exhaust cam advance more EGR, less advance less EGR?? Last edited by kkowalsk; 02-03-2010 at 08:21 AM.. |

Great VID! 1:24 and after is the best demonstration. This is exactly how mine sounded pre-head replacement. You are a prime candidate for that. Don't despair you will have a perfect engine with persistence.

so thats a good thing. The thing that sucks is I have to drive 150 miles each way to have it done. The dealership here in Madison doesn't like me, my car or it's mods. |

^^ lucky, I wish my SA or GM was that easy to handle, at least for THIS issue.
jrjinsa, I think mine is Normal, It sometimes get loud and even when I hear it after it is warm, it is very slightly noticable. Thanks again for your help on making me at least feel better about it, and thanks to ALL who have helped us in this entire sticky

Just got back from service where the exhaust cam lifters were replaced under warranty.
Took a little persuading but they acknowledged the problem and did the fix. |

Got my car back today after the cylinder head replacement. There were so many part numbers that I just took a pic instead! yeah i know, lazy!
SA said the parts would have been $6,200 and another $1,300 for the labor.

Well, shoot. 49.2k smooth quiet engine miles and this morning my engine's ticktickticking. It never did this even after several days sitting ice cold 20F. Warming it up didn't stop it. I think I'm 3 weeks away from the end of the original warranty, although I have CPO for another 2 years. I know it's pretty harmless, but should I take it in or forget it?

What did you say to the SA? (Just noticed the ticking today at the drive thru, didn't bother to read the entire thread)

HVA didn't eliminate all the tapping from mine. They are replacing the cylinder head now.
