How to remove dowel pin from the block?
The pin that holds the pilot bearing down got crushed down a bit, it's probably half has high as a regular 'good' one. How can I get this thing out to replace it?

use a torch, heat up around the dowel, not the dowel itself, expand the block with heat.. keep heat away from the dowel. it will either fall out all by itself, or need your assistance with vice grips.

I am guessing that you mean the front main bearing pin. It does not have to stick out much – just enough that the bearing does not rotate. It’s a roll pin (made of roller sheetmetal) – you should be able to coax it out with a pliers – you may need a new one if it gets buggered up!

The pilot bearing is the sealed bearing that fits in the rear end of the crank where the driveshaft fits in.

Where did you get that part number? It appears to be an actual dowel pin (solid) rather than the roll pin you are looking for. It's hard to tell from the picture if it is too low (it does look low though) -- have you tried putting the bearing in there and seeing if the pin still feels like it is providing a mechanical lock?

I did put a bearing in there and felt nothing lock it down, but it doesn't want to spin either. It's too short to get a real grip on it with pliers of any sort.

If it were in my shop I would tack weld (Tig) a piece of steel to it and pull it out.
I don’t think there is a part number – its just standard roll pin material – any good fastener place will have it.
If you buy a new block from Porsche the roll pin comes free with it…..
