Engine ticking sound

Hello All,

I'm experiencing what I believe is a variation of the N52 engine valve lifter ticking issue. My symptoms are as follows:

- At startup (cold engine), no ticking.
- When idling (warm engine after driving), slight ticking.
- Above idle, no ticking.

The ticking is never severe. Are these symptoms cause for concern or normal? The car runs fine.

Thanks
cinergi

usually a VANOS or lifters issue. Search it.

Thanks Bad Debt, I've read about the lifter issue, BMW's TSB on this topic, and its resolution involving the replacement of valvetrain parts and in some cases the entire head, with varying degrees of success. However, my symptoms seem slightly different in that there's NO ticking at cold startup, and slight ticking only at idle when warm (disappears above idle). Also, in the threads I've read there seems to be no consensus on whether this issue is harmful to the engine (BMW claims it's not, some others claim it is). I'm wondering if it is in fact harmful, because otherwise I can live with the slight noise since my car is out of warranty and replacing valvetrain parts or the entire head are very costly and in my view drastic measures.

Thanks!

How about worn timing chain guides?

cinergi,,,,Try getting a piece of wood 1/2 inch by 1/2 18 inches long (I kno,,, sounds primitive ) put one end on any engine part while running and the other end on your ear. Wood has a great transfer of sound, ull b amazed at how good all the engines sounds travel through the stick. It will pin point the location of the ticking sound.
Even a long screw driver will work but I think the wood stick pics up sounds better...Put the end of the stick on your injectors, valve covers, timing covers ect.. Im Positive you will locate the sound this way. its worked great for me in the past. Its a cheap, primitive but very effective tool

Thanks everyone. The sound definitely comes from the valve train. Since it's so minor and only happens at idle with the engine warm, and since I can't really do anything about it without spending lots of money for BMW's updated engine head design, I'll live with it. I can't even hear it unless I'm outside the car standing right in front of the engine in a quiet location.
