Thumbs down Timing Chain Replacement

Hey all,

I was going through the service manual today, and found nothing on Timing Chain maintenance.

Was wondering, has anyone replaced it yet and what is the maintenance recommendation for it?

I already bought an aux drive belt and was planning to do both soon.

Thanks!!!

Generally speaking you shouldn't have to replace a timing chain for the life of the engine. They don't tend to wear out like a rubber composite timing belt does.

If you mean timing belt which is the rubber one, I replaced mine at 70k miles on a 2003 X5. Because at winter start ups, it really gives that really loud squeaking noise.

I traded the X5 on 2011

The timing chain tensioner have been a real problem. Make sure you have your dealer check it when you have it serviced. I just chained a timing chain 2003 316ti. The tensioner caused my problem.

Changed the timing belt on the wife's Hyundai Tucson this summer... 6hr. PITA. I'm glad these BMW's don't have one.

Re: Timing Chain Replacement

Somewhere around 150k mi, it is a good idea to replace the tensioner spring. It's cheap and easy.
