I need to do guides on the 4.6 I think, it got noisy all of a sudden.

Currently sidelined while I research parts needed.

I have a good idea about replacing the main chain guides reading other posts and looking at realoem, but what I am not sure of is the 2 camshaft chains and their parts.

I see people have done just the main guides, and some that do the cam chain/guides/tensioners too, basically the entire engine timing mechanism.

Interested to hear your opinions on this, espcially those that have done it.

It only has 55k lol but it's old so I guess age did it in.
