3rd gen cctl?
 

My 06 f4i came stock with the updated cam chain tensioner lifter [14520-mbw-j23] and it lasted 28,000 miles before rattle and is now at 31,000 with no problems. So I orderd a new stock one and got a 14520-mbw-j24. I cannot find this part number in the parts catalogs online and want to make sure its the right one before I put it in. I also couldn't find anything about it using the search function. Anyone know about it?

yea its just the next design after j23...figure after 24 revisions they might get it right

they wont.. you would be better off with ordering a manual cct from APE. but since you already ordered it you'll get piece of mind for a lilttle while then you'll be replacing it again.

Right, in another 28,000 miles. Besides, cam chain tension changes depending on acceleration or deceleration which the manual one dosen't adjust for like the stock one does.

Go to this web site and and there is a easy fix that Uncle Jeff has come up with.Here it is
CBRWorld.net - OEM CCT MODIFICATION PIC'S he seem to know what he is talking about he has wrote alot on the bb noise check it out and let me know what you think I am going to try it.

This is where I stand also... Even though it rattles I'll stick with the auto-adjusting tensioner. It is just safer.
