I'm going to replace all 4 guides. #20, 6, 14, 7 as well as #11 the tensioner #17, 18 and 19. I'm also going to replace the bolt #12 and washer #13. Should I replace any of the other bolts? #15 and 16? How about 8,9,10? My cam gears #4 are in great shape so they are going to stay along with the crank gear #2 and I figured I'd keep the chain #1 because from what I understand the gears and chain should be allowed to wear together.
I'm also going to replace all the gaskets. Upper and Lower front chain case cover 11-14-1-721-802 and 11-14-1-721-802. Thermostat housing #11-53-1-721-172. Front crankshaft seal 11-14-1-439-570. Top of lower chain case gaskets #11-14-1-247-837 and 11-14-1-247-849. Lastly the Valve cover and spark plug gaskets #11-12-1-721-876, 11-12-1-721-475 and 11-12-1-721-476 (x3).
Is there anything else I'm missing? Anything else I should do while I have it all apart?
The PO said the thermostat and water pump were recently replaced. I may do the thermostat because its cheep and I'll have to take it out anyway.

I'd be tempted to add the rear timing case gasket. I'd also see if there is a spec anywhere for timing chain maximum permissible length (stretch).
You might want to put in a different temp thermostat while you're at it. OEM is 88degF IIRC. Do a cooler one for better performance or a hotter one for better mileage & longer engine life.
-
Don't replace the case/block gasket unless you have to. Do you k ownif your profile gasket was ever changed? It was recalled a long time ago.
-
Main things missing are the crankshaft bolt and a chain.
You don't need 16 and 19.
You probably don't need 12,13 and 15
9 and 10 have to be upgraded to the new longer bolt.
You don't need the inner case profile gasket.
Just buy a valve cover gasket kit that includes the rubber seals for the bolts.

Yes BMW of seattle did it at 60,000mi for over $1500.

I wasn't going to do the chain because I'm not replacing the cam gears or crank gear. I always thought the chain and gears should be replaced as a unit. I'll add 9 and 10 to the list. 19 is out too, I thought it was part of the tensioner at first.
What bolts are you taking about with the valve cove gasket? The one from Pelican comes with the parts I have listed.
-
If you don't do the chain you will have what RED IS 91 had in the bottom of his pan.
Looks like pelican's kit doesn't have the rubber seals (Part #11-12-1-721-879) in it's kit.

Well I didn't know about that with the thermostat
How much difference will a cooler one make

A little. I haven't run one for long enough to give a qualitative answer. I'm just going on conventional wisdom. With 277k miles IDK if it'll run long enough either...

A little off topic but what wheels are those in your sig Carlos?
