help! the lower pin on the drivers side timing chain guide is frozen solid. Somebody brilliant tell me how to get it out!

There are writeups how to make a cheap pin puller. Search timing chain guide replacement.

What method of removal isn't working for you?

inserted bolt, shimmed to 2 washers short, tightened. this normally works fine just adding washers as pin comes out but whoever did this before drove pin back in until it bottomed out (about 1/8" recess). pulled threads tightening. Going to try drilling corrosion out, threading in bolt with jb weld, making threaded collar out of 3/8 bolt and nut. Let you know how it works. Never had this problem before.

Worse comes to worse the opposite end of that lower pin can be accessed from the rear by grinding away a small area of the alloy cylinder head on the backside. Then the pin can be tapped to break it loose or driven out towards the front of the engine is the internal threading is completely useless.

I always run a tap down into the pin's threads first and then clean them up before threading whatever puller into them, you want the maximum connection you can achieve on the first attempt to pull it.

Be sure you are filling all the threads with bolt before trying to pull.

You need to get at least six threads (six complete 360 degree turns) of the bolt into the pin to get about 95% of the theoretical strength of the pin/bolt combination.

You also need to make SURE your washer assembly or whatever is dead flat so the bolt pulls directly out and not to the side at all.

Heat can always help. Plug in the block heater for an hour, apply the blue wrench to the area. Once the head is nice and hot (and the hole is as big as possible) try rapidly cooling the pin and then pulling it out. Canned air, turned upside down, shoots out very cold liquid. Be careful of freezer burns!

I did that to access the back side and drive it out with a punch. I then replaced the pin with a hardened bolt and lock nut.
