is my water (cooling)tank too high?
« on: October 18, 2023, 06:23:20 PM »
was thinking about how the water pressure of having the water up high like I do might be lending itself to possible water leaks.  I haven't seen any this season, but in the past, I've had seepage at the top, beneath the rocker holder block.

Of course, I'd rather not change anything, but would love any thoughts.

top of tank - the into-the-tank point, where the water line is - is about 30 inches 75cm above water outlet of my 6/1.

When I was using a cooling tank the set-up was much like yours. My tank was a bit higher. The bottom fitting on the cooling tank was at least a foot above the bottom fitting on the engine. As a rule of thumb, about 2.6 column of water will give you approximately 1 psi of water pressure. Your cooling system would actually be a bit (just a bit) more efficient with the tank a bit higher. That said, if the circulation is working OK as it is, leave it alone! You are in the ball park.
Eventually, I replaced the 30 gallon cooling tank with a cast iron radiator, but that was for other reasons......less anti-freeze and a faster warm-up without using a thermostat.

Oh, I forgot to add: when using the Indian sandwich type head gasket, you can soak it in a silicone base grout sealer or seal the exposed edges with Permetex Aviation gasket sealer to prevent coolant from wicking into the fabric(?) part of the gasket

Doggoneit Hugh!  And here I was, beating my head against the wall....trying to figure out HOW I still had a weeping leak from my head gasket!  Your thoughts here are much appreciated.

@Powdermonkey:
Thanks for the kind words, I an just repeating what I learned from some of the older posters from years back. I have tried their ideas and they worked for me.
There unfortunately has been a lot of good (and some pure B.S.) info and threads with interesting characters that have been lost in the various LEF web hosting changes and upgrades over the years.
Cheers

Yes, I think that the diluted Aviation Gasket sealer trick (Hotater?) was originally posted about 18 years ago.  I also tried it and it worked great.
