Anybody know timing chains

Getting ready to do my long over due timeing chain and guide replacement on my 2003 2.7 because its been strongly sugested to me to do this. Whats the best kits i can get for this project?? And also Ive been told that their is a slight modification that I could do with the timing on these engines that can improve performance?? Anybody know anything about that?

 

OEM parts a mod is just advancing or retarding timing, , just do the chain ,and call it good the mods won't help at all

 

AFAIK, chains are considered a life-time part. I'll change it when it starts to get noisy.

When I rebuilt my 22R (needed rings) many years ago, I decided to change out the chain at the same time. I couldn't tell the difference between the old one (with 200k miles on it) and the new OEM one. The plastic chain guides were shot, however, and the tensioner was badly worn.

 

Unless something is wrong with it why change it?

what the above two posters said.

Why change it unless it is stretched or the guides are bad....IF the oil is changed regularly, the chains last a very long time.

 

It could be eliminating the 'vibration damper' mechanism. It uses a second timing chain. Supposedly, you can get a kit that eliminates that additional rotating hardware. I don't know if it really does any good.
