On my '29 roadster I had to remove the distributor once and that included removing the #8 stud nut. Some coolent {Sierra brand anti-freeze & water} came out with the stud when I tried to back off the nut. The stud was out for about a day. After replacing the dizzy and the pop-out cable clamp on #8 stud. I drained
the oil and found only a very little coolent in it. However, I added new oil.
Re-torqued all the head nuts and since then I have just barely cracked the oil drain plug twice. To check for coolent leakage, first time one drop came out. The second time no coolent. I only use distilled water and water pump lube/rust inhibitor now as a coolent.
And when I add my new Snyder 5.5 head I am going to remove the #8 stud pop-out cable clamp!
