Timing Chain Repair
I finally got around to starting the job.
I made an engine support that looks like the one in the service manual.
Took off the cam cover, belt, tensioner, engine mount, and front cover.
The non-adjustable chain guide was in 3 pieces.
Now comes the bonus hard part. The upper bolt for the non-adjustable chain guide was snapped off flush with the hole. The one that you can only access by removing the access plug in the head. So now I have to drill and easy-out the broken part without actually being able to see it directly. The only way to look directly at it would be to pull the head or the engine.
Luckily there is enough room to get an angle-head drill between the inner fender and the hole. Tomorrow I'll probably tackle it.

I have a question: Where did you guys buy the bolts for the crank pulley and the cam gears? These can't be reused and I haven't found them at the web sites for the auto parts stores. Are these dealer parts only, or do they actually have them at the parts stores?
Thanks

Dealer. They aren't stretch bolts, so ........
I will try to check with a mechanic later today, but I don't think they really use new bolts. I think that's a CYA instruction.
I am not an authority, though.

Well, the broken screw doesn't want to come out. I drilled it (not exactly centered but not wildly off) and tried an easy-out but it just breaks loose from the screw or pieces of the screw break off. I also noticed that the original broken off screw head part had wobbled around the hole and did some damage to the aluminum (gouging, etc.).
I could drill out the hole larger and use an insert, but I don't know how much material there is around the original hole (I don't want to break through the aluminum or weaken it).
The next step might be to remove the head and take it to a speed shop so they can bore it out with their horizontal drill through the access plug and put an insert in. I'll call them first to get their opinion before I take anything off.
