Car has 100,000 miles and I'm about to change the timing chain guides and chains. What else should I replace when taking everything apart? I don't wanna have to take this apart at this scale again for at least another 100k miles so start naming things. Thank you for the help!
It's a long list. Make sure you crimp the vanos and replace the seals. Water pump, all the small hoses, the oil separator, chain tightener, tons of gaskets and seals.
You can pull a valve cover or drop the pan to inspect why do you think the guides need to be done? Mine went 172k and they were still in good shape.

Most of this can be done when needed but if you are just throwing money at it why not go all the way.

Agreed, anything you have to take off, replace, anything that is easier to get to while you are in there, replace.

You can check by taking off a valve cover? and I bout the car at 96k miles and its sounds somewhat diesel like as they say it can get but I've never head a good hear of one brand new so I don't know if its just fine rn or they are going out. I just don't wanna waste my 100k engine. I'd love to have some help to know if I can wait though, would allow me to put money somewhere is on it.
As mention above id drop the oil pan and check for any guides materials (pending if the oil pan haven't been dropped before). If all is good, I'd just replace the timing chain tensioner, change the oil out <10K miles or 1 year and keep an ear out for distinctive metallic rhythmic rattle at all range of engine rpm.
I think somewhere in 1998 is when they started to introduce vanos, only way to tell is you can see a vanos solenoid on the upper front timing chain cover on both bank. Most vanos will rattle when they age (hence diesel sound) though harmless it will affect the performance and torque linearity.
Im in the same predicament im at 120k miles and my engine sounds like diesel tractor at idle, and when accelerating I can feel engine is doing some strange rubber band effect under load between 2500-4000 rpm, so im probally will tackle the vanos and everything else in between which will likely cost about more then what I've bought the vehicle for (1500-2000 in parts alone) but it will be something i will tackle eventually.

Are the chain guides broke or do you want to just spend plenty of $$$$. If they run fine, keep changing oil at good intervals and drive it.
