[Fot] Cylinder head freeze plug help

[Jack Wheeler]

Hi Jim.  Consider this.  Pulling the head may give you the most correct fit, and also may be quicker, all things considered.  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.

Jack

PS.  have you determined what caused the freeze plug to blow out?  The one time I had that happen at the race track, it was the result of a major cylinder head failure.  You may be looking at a bigger problem than just the freeze plug.

 I used one of those expandable core plugs on a BMW 2002 and left it in for the next 60,000 miles with no sign of leaks.

Duncan,

I think that’s where I’m going next, the freeze plug is just about in line with

the bottom of the dash or close. The good thing is it blew the old plug completely out.

I just need to knock a new one in.

I’m pretty sure I can go under the dash and through with a piece of ½ or even ¾” round

bar about 2’ long which I can scrounge at work.

I’ll have to remove some stuff but still better than pulling the head.

Can you drill a hole through the firewall and drive it out or yank it out that way?

I was wondering if anyone has a clever method of putting in a cylinder head freeze plug without removing the head.

I was instructing at our drivers school this past weekend when it blew out.

I may have enough room between the firewall to use a short blunt air chisel

but I have my doubts so if anyone has a better one please let me know.

Thanks as always,

jim g
