I read on other forums that if you replace the chain tensioners one at a time, there is no need to lock the cams.
Although i get it that buying the tools and plugs and locking is "safer" is there really a big risk in doing one at a time?
Also if in the future I replace chain guides, can that be done without removing the engine reasonably?
Thanks

I think there are 3 tensioners on this 5-chain engine.
I’m pretty sure the IMS chain guide cannot be replaced without splitting the case.

Yes u can do the tensioners without locking. U still may want to put a pin in the harmonic pulley so nothing spins.
I would not recommend doing the variocam pads jn the car although it can be done. Its very tight and u have to get creative on a couple of the proceedural steps.
Just drop the motor its more to do but it may even be quicker in the long run.

In the 5 chain engine you can replace all the pads except for the Crank to IMS chain pad without splitting the cases but you will have to drop the engine, remove cams and other items.

I would still change the tensioner but don’t be shocked if the noise is still present. The 99’s had an earlier version of Lokasil that creates some noise like you describe for the first 30-60 seconds after a cold start. My 99 has done it for the 10 years that I’ve owned it even though I changed all three tensioners.

I don’t recall if it came with the crush washers. You might search the PET and see if they are the same size as the crush washer(s) used on the manual transmission plug(s).
