[Fot] Cylinder head freeze plug help

Jack,

The old freeze plug was found last night under my catch tank at the battery tray. It didn't have much of a ding in it

so I suspect it could have been flattened more/better when it was first put in.

Last night I was able to clear stuff as required to drill a 1/2" hole in the firewall directly behind the plug.

I already have a length of 1/2" solid round bar, tapered/rounded at the end in the hole just waiting for the new plug to arrive.

The round bar runs right under the dash. I'll be able to knock it in from the cockpit with a 3 pounder.

The car was running better than ever when it went, compression is at 200 psi on all four so at the moment

I don't have any reason to believe there are other problems. No evidence at all of water in the oil or cylinders.

However, once the plug is replaced and running again there will be detailed inspections once it's back up to running temp.

When I was racing, and had to pull the head at the race track, I could get it off and back on, new head gasket, and nuts torqued, in under an hour.  By the time you make clearance under the dash, and drive the plug in, possibly not aligned correctly, I'll bet you will have over an hour invested.  Good luck.
