Stuck cylinder head plug

Do whatever you have to do to get that plug out, then e-mail me your address and I'll send you another one.

Thanks Steell. I bought a bolt extractor at Lowes. I think it'll get the broken bolt out. Then I have to try removing the plug again.

I'll start with another bolt and be more careful about torquing it down too hard. I tried pulling and levering the thing with vice grips and just couldn't get it to budge.

I'll try heat and some penetrating oil to see if that does the job.

If I maul the plug during removal I'll take you up on your offer.

Here is how I get them out: you use the 10mm cam cover bolts. Thread one all the way into the cap plug, but don't torque it hard. Then lay a piece of wood across the top of the head (I think I used a paint stir stick) and situate it so it is near the head of the bolt and about level with it. Then get an open end wrench and use it to pry under the head of the bolt in the cap plug using the wood piece for the fulcrum of the lever. That always works for me.

Kroil is good if you can get some.

An open end wrench sounds like a good idea. I don't know why I didn't think of that.
