2001 740il timing chain guides....

[Ethan89]

I have been an avid e38 owner ever since I bought my first 2001 740 in college I love the cars and I usually just drive them until the guides tear the engine apart then I buy a new one. This time around Im looking to be proactive and replace the guides before they destroy the car I have been through all the threads and watched a ton of videos my main question is which aftermarket guides last the longest? I've heard some say the aftermarkets are better then the originals and Visa versa just want to hear from someone who has done a few and can tell me who makes the longest lasting guides I don't want to have to do this again anytime soon.

Bmw guides are the best, I'm experimenting with the Febi guides now, still good at 5k miles

I myself would go with the factory guides and rails.
