how often or how man miles should my timing chain be replaced at?

 

Never. They are made of "search type steel".

 

I just laughed my *ss off. Thank you.

 

Our timing chain srt weak and tend to stretch out at 40 k from what I read . I'm long over due with 150 k. Going to be getting mine installed so I don't have that lag off the line anymore .

It's something you don't notice till you replace it .

 

wow lol i guess i should prob change mine 115,xxx

 

mine was shot at 125,000 so i'd say at least every 100,000 or so - or better yet - every time the water pump is replaced, however often that might be.
