Going back through the records, at 101k the water pump ac drive belt, ac belt tensioner, acc tensioner pulley with lever, and ac tensioner pulley with lever was done o rings etc., drive belt. Acc belt tensioner tons of o rings lol., thermostat or ING, camshaft solenoid gasket, adjuster seat, timing cover seal strips. Hoses were done prior to that.


Based on all this I think I can just do the complete timing chains and guides and not have to do the water pumps etc.

But if there is somethingim missing let me know. I just got the bently manual and will try and learn more. Someone mentioned CCV. What is that?

Thanks. I may not be a diyer but am an enthusiast. My last bmw was an e24 that I did a full ground up on. Loved that car. But that car was the beginning of the end of my marriage. Lol. It was worth it!


Thanks again for sharing your knowledge.

That's exactly what I meant. You reuse WP and of course buy the new gasket. The problem with kits you either waste money on parts or kit doesn't enough parts since every car has a different repair history.
While it does make your car being longer down, I always advise to tear everything down first since that way you exactly know what you do and don't need.
Besides Bentley, familiarize yourself wit REALOEM and for example that's where you'll see what they meant by CCV:

Being serious DIY, I have respect for very few Indy's and none for dealers. Most of them tell you we've done bunch of these, we know what we doing... bla bla.
While I made plenty of mistakes, I know I've done them and I'll correct them. You take car somewhere for TC guides, you're basically playing lottery who's going to be working on you car and how professional they feel that day.
