Any tricks to remove one that seems to be stuck in full flowed case besides buying below tool.

Hit it with compressed air somewhere with no Spring installed?
Bump the motor over with no spring installed & no ignition so it won't start?
Any tricks?

Would have to weld a rod on the end of a tap to do it that way.

Anything?

Use a wooden dowel with a taper on one end and wedge it in the bore of the piston, or I've used a large slotted screw driver the same way.

I've used my pocket magnet and some carb.cleaner. If that doesn't work a long curved pick that fits inside of the plunger & some digging will get it- just be careful not to stick yourself with it (that hurts)- sears sells some picks that fit.

Use a tap. Screw it in the piston and use a pliers to work it out. I can't remember the size but I think it's 1/2".

One of the guys in our VW gang tried for hours with a puller, tap, cussing, etc. Finally he cleaned the cup real good with brake clean, let it dry and then used a long bolt and some JB weld and JB welded the head of the bolt in the piston cup. He let it dry overnight and then pulled it out ...worked great. Just be very careful that you don't get JB weld in the bore...just the piston cup.

I've never had a tap not work for me. M12 tap.

You could try some air pressure into oil pressure sender port and see it it blows plunger out, if that does not work, see above....

"I've never had a tap not work for me. M12 tap."

I may be dumb but I thought the tap won't be long enough to stick out of the case so there will be no way to grab the end and turn.

A tap should be long enough, the piston isn't that deep.

Yes it is long enough - that plunger and tap that I pictured above, I just went and took this picture of them in an engine block with the piston all the way at the top of its travel:

My son made the comment of heating the block and using a magnet. Strong magnet and about 10 seconds with propane torch equals: Dad/0 and son/1. :oops:

What's the best way to get the big screw plugs off? I don't have a big enough screwdriver. Is there some trick to loosen them or should I just go out and buy a big ass screwdriver? Does it help to heat them up a bit? thanks

Yes, take a big screwdriver and put it at an angle to the lip of the plug that you would normally turn counter clockwise to unscrew and hit it with a big hammer-that should knock it loose.

They have screwdriver attachments for ratchets that are about 3/4" wide. They work perfect.

If you have a 3/8" impact driver, the kind you smack with a hammer, get a drag link socket.

The DL socket........

along with the impact driver

make short work of removing those plugs.

Thanks Roy and turbo, I thought such a tool may have existed but wasn't sure.

Thu Nov 06, 2008 10:43 am

Yeah, and here's my socket - thanks for mentioning the name of it - the drag link tool, as I'd forgot that name, I just knew it was some suspension tool. I found mine at a used tool stand at an indoor flea market/antique store. And I've never once needed to use a hand impact with it, just a breaker bar was more than sufficient.

Why would you want to put a direct flame on a magnesium engine case?

I use a wide chisel bit that came with my air hammer. I use a wrench on it.
