Default Tricks for removing distributor cap "snout"?

In the process of installing a cam advance key, new belt, and WP on my NA and I have everything off the car except the cam gear. I can't get this part out: (not my picture)





I've heated up the sleeve around it with a torch and grabbed it with vice grips but can't get it to budge. Tips or tricks? Car is distributorless so destructive removal is ok...although I'm trying to avoid drilling.

you could tap the hole in the end of it for a bolt/slide hammer.
i've had to channel-lock those things before.
if you can get it to rotate in place it will eventually slide out.

I had to use vise grips as tight as I could get them and the used a hammer on the vise grips to break it lose. Heat didn't seem to help. I don't think I had to hit it too hard with the hammer to break it lose, but it was still a lot of work to get out even after I got it moving.

I would think these snout pieces would be easy to replicate in Delrin, and you'd never have to worry about them seizing. As a side benefit, I've noticed holes I've tapped in Delrin always impart a tighter fit on the screws going into it, which could work to reduce the likelihood of the rotor ever coming loose, as is known to happen with these.

Michael didn't we get them out on my cam towers with judicious use the blue wrench and lots of hammering?

The rotor coming loose is the consequence of people over-tightening the little bolt that holds it in place - the threads strip and the bolt falls out...
Delrin is good stuff but the steel part is just fine.

Just a tiny little tweak with a hand wrench on the 7mm? or whatever size it is.
I don't even use threadlocker there.

To the people working on these things - it helps to put a little bit of oil/grease on the "snout" part that sits inside the cam gear so it doesn't seize up.

Seems that I remember that there is a key somewhere in the mix...perhaps if you can get that out, the rest will slide off OK. You might have to block the cam gear and put a killer wrench on the hex. The key is softer than the nose piece, but you might wipe out the keyway inside the hex, like I did on mine when I was doing the initial disassembly..Seems that Haynes forgot to tell anyone about the bolt inside the nose piece..DUH!
