Headbolt washers!

[100IH]

In response to Mikeinnj's post above, I would like to add - a coolant leak in any cylinder will raise the temperature in that hole and will also clean house on the oily residue and the hard carbon deposits, all visible on the plugs and the top of the piston.

I have also seen the porcelain that surrounds the electrode on the spark plug get a hair line crack from firing in a cylinder that has a HG issue

Also, why use WD40? Are you trying to remove moisture from the nuts? WD40 stands for "Water Displacing, formula #40". It's not much of a lubricant! Nor a very good penetrant!

Obviously you have not been shopping for a penetrant lately. WD40 has one!! The line is not just limited to displacing water anymore. Since I can't find Maltbees anymore, now, back in the day, THAT was a penetrant!

One problem with checking the washers for the grade is, they are already under the nuts and tight, somewhat. So, IF I decide to check for the Rockwell, I will just remove them all together. Also, just so there is no confusion, the Grade on a bolt is a shear strength test, not a pressure/smash/squash test.

So, I think with all the opinions and conjecture I will just spool up that rusty hard drive and go with what I remember from my childhood and growing up with Model A's. Clean the radiator to make sure it is still good, maybe make a new water pump, toss a set of points in the distributor and reset the timing, and make this run like it should.

You can still get Maltbees but you have to buy a case. http://maltbystore.com/
