I have a 99 z24 with the 2.4 LD9. About 200 miles ago, The water pump started leaking, so I had the water pump, timing chain, guides, tensioner, and cam sprockets replaced with the PCI preffered components timing chain kit. Ever since I had these parts replaced I have been getting slight timing chain rattle briefly for about the first 2 seconds after a cold startup.
I have read about people converting to the older style mechanical timing chain tensioner that came on 1996 year LD9's, However on partsdinosaur it says that the mechanical style tensioner is strictly for 96 model engines only and NOT to use that tensioner on 97+ engines.
It seems to me that the hydraulic tensioner would have to be removed when converting to the older mechanical style tensioner, however wouldn't this cause oil to leak out of the engine block where the hydraulic tensioner bolts on ??? I would like to hear from people who have converted to the older style mechanical tensioner. Please
!!!!
There are two versions still used. A one piece and a two piece. I can not remember which on is better though without looking through old posts.

I prefer the 1 piece design (which is strictly mechanical). It is from a 96.
The 2 piece design is both, but really hydraulic. I have had many many issues with these even new.
The only real thing you have to do to use the 1 piece is remove the stud that is used to hold the shoe on for the 2 piece unit.
I have been running the 1 piece design for over 100k no issues.

Does the mechanical tensioner bolt up in the exact same place as the hydraulic tensioner ?
Nevermind, I feel like an idiot ! Somehow I had the idea that the mechanical tensioner bolted up to the block in an entire different location than the hydraulic tensioner. I'm Not sure why I was thinking that. Upon further research I have found that the mechanical tensioner bolts up in the exact same location as the hydraulic tensioner. I still don't understand why partsdinosaur say DO NOT use the mechanical tensioner on any 97+ models...
