Im installing new head gaskets in my car and removed the dowel pins to clean the surface, one pin will not come out. I've put vise grips on it and it will turn but it wont come out. I dont want to put any upward force on it. Im scared to mess up the deck surface.

I got the surface clean around it, but now it has to be replaced because its burred up, the other possibility is to clean the burs off with a dremel but the the pin will be smalled. Will this cause an issue?

Any ideas?

Thanks

Leave it alone and clean around it. Use a wire wheel on a drill.

I wouldn't want to use a smalled pin.

put a little heat on it and the try and pull it out... usually works pretty well

There is a seam in the dowel, rotate it around where you can take a punch and hit one side of the seam and fold it in. Grab the folded in part with needle nose vise grips and pull it out.

those dowles should be solid in that block...........heat it up and pull it out thats how i got mine out

Woops, your right.

Grab it with a par of side cutters laying flat on the block, push the handle down to pull the dowel up.

Drill a small hole down thru the dowel. Drill and tap the top of the dowel with 1/8 npt and screw in a grease zerk. Pump the dowel out with high pressure grease.

I would just leave it alone and clean around it.

No need to over complicate things, it wont hurt anything to leave it. Why risk possibly marring or scratching the head surface?

The dowel pin had too many burs on it to even fit the gasket over. I ended up clamping it with vise grips with a slide hammer attachment. Worked like a charm. Hopefully I can get this thing together this week for the final track day this weekend.

Thanks for the ideas guys

I know I'm bringing this back from the dead. Did you guys heat the pin itself, around the pin or both? I tried the area around the pin and just ended up grinding into the pin with my channellocks but couldn't get it to turn or move. Now it's kind of deformed and I can't even get the head gasket over it.

I wouldnt heat the pin itself. You can heat around it. Heating the pin will expand the pin and make it tighter. Do you have a slide hammer or can you rent one from the parts store?

To keep from scarring up the deck: lay a piece of paperboard (cereal box, etc.) with a hole in it over the dowel, place a large fender washer on top of that, chamfered side down/ flat side up. You could try a stud extractor with that extra protection in place.

So I ended up getting 3 of them out with some ice packs and vice grips. The 4th I crushed with the grips. I tried getting a stud remover on it but that didn't work as it was so crushed already. I ended up having to drill it out. No fun.
