I was using the washer/bolt method to remove the upper timing chain guide and it went great for the upper pin. However, the lower pin seems to be stuck real good. I've been hitting it with PB but it hasn't helped yet.

When I first put the bolt in I stripped a few threads out of the pin so I took some washers off to get further into the pin. It worked well as the bolt went much further into the pin, however once I got to the point where I thought the pin was about to pop, the bolt broke instead. Now I've got a partially stripped pin with a bolt stuck in it.

The bolt should be easy enough to get back out since it's covered in PB but I think if I just try the same thing again with a new bolt I will break the bolt off in the pin again.

Does anyone have any ideas?

That happened too me once. I was able to get a prying device inback of the pin and get it out. (pull at the same time) Now when I pull one I get WAY down in the threads and just go a little ways at a time.

Now I've got an ez out broken off in a screw that is stuck in the pin. Maybe I should just stop "working" on it for now.

How did you get a pry bar behind the pin? The pin hasn't budged at all yet.

Well it looks like I'm totally screwed, there's no way I'm drilling through a hardened ez out. If anyone has any ideas please let me know before I try something stupid.

So here's my idea; I'm going to drill through the back of the head and then push the pin out from behind with a punch. Whadda ya think?

How good are you with a torch?

I broke an easy-out in a bolt on a furnace. I thought I was toast.

Took the torch and very carefully melted and burned away the easy out.

Decided to increase the drill size until I finally reached the minor diameter of the threads. Then took the tap and rethreaded it. By some miracle it picks up the old threads. Did it three times on three different bolts.

Now, I caution you..........the furnace was cast iron...........the head is aluminum.

If you ever can get back to the threads in the pin, it might make more sense to rig up a slide hammer type puller. The screw can take quite a bit of force in tension...........probably more than the pin needs to move............but the screw can't take it in torsion.
