I've read to remove a freeze plug...Use a center punch and drive a hole in the center of the plug and then pry the plug out. How close is the camshaft? will I run the risk of hitting the camshaft behind the plug? Do you need a tool to reinstall a new plug?Thanks,
Kevin

Sometimes that plug gets knocked loose when you install the cam. Try using a large socket and tapping it in a bit. If it moves much, it probably will seal again.

clean it good and run a bead of black sealer around it. be sure its all the way in, ping around it with a punch.Last edited by lt1s10; 08-24-2006 at 04:46 PM.

Thanks everyone.
I'll give all those suggestions a try.
Are these tapered holes in the block? Is that what tightens the plug, or
is it the plug expanding while being tapped in?
I'm a little reluctant to put a bead of RTV around the plug. If I do that, I'm sure it will seal...but for how long?, with the engine running at temperature and full oil pressure. Of course at that point in time the engine will be in the car.
I will try to press it in a little more and take it from there. How much room do I have before I hit the camshaft? Speaking of which...What holds the camshaft in position?As I recall I slid it in, attached the sprocket and chain and thats it. Is the chain the only thing that keeps the shaft from wondering?
Thanks,
Kevin

The plug was square and flush with the block. I Tapped it in a little further, about a 1/16th of an inch (It moved fairly easy).
BTW The plug is 2 7/64th.
Still leaks?Thanks,

they should have sealed it when they knocked it in. they are made to go in pretty easy, but hard to get out. it must have a dent in it.Mike

BTW for anybody that may have similar questions down the road...
The distance from the edge of the block to the cam is about .450
There is a lip at about .420 so the plug can't be driven in beyond that. But you can't drive the plug to the lip because the plug is bowed out so the center of the plug would hit the cam shaft before the outside edge came in contact with the lip in the block.Thanks,

Denny do you have any thoughts on your previous post mentioning "setting the cam distance"? I really don't want to go any further not knowing if I missed something. I did not set the cam to any reference whatsoever. Thanks again for all your help.Thanks,

Ditto on the model kits! My best were lost when the Hobby Shop burned under suspicious circumstances....
How did you get hooked on cars?
