Canton expansion tank question
For those of you running canton or other aftermarket tanks.
Do you notice coolant venting once in awhile out the side vent hole on the neck of the tank. (See picture)
Cooling system has been completely overhauled and bled multiple times. Level in the expansion tank is about half way. Also did a pressure test on the system and the cap. Both pass flying colors.
No issues with overheating.
just random it weeps out this hole.
Not sure if it’s normal or not.

While everything tests ok, it could be a simple matter of the height of the neck and overflow spout on the tank not being optimal for the depth of the spring gasket in the cap. Allowing a small amount of fluid or at high pressure only.
I'd do the same, simply route the overflow out of the engine compartment and keep an eye on it for now.

I have one of the Canton tank and had the suggested pressure cap on mine the pressure was too high. When the car would get warmer than normal it would never open the cap and leak out to the overflow it would push past one of the hoses on the radiator, I ended up going with the Canton 16lbs cap instead

My Mini will spit coolant after a long session of intense track driving, and me no-worry as long as I check the level regularly.

I may be missing something. But my brain tells me routing the overflow hose higher or lower will not make an iota of difference. The hose is there just to direct the release of excessive pressure of steam/liquid. You likely don't have a problem. Just let the coolant lower than half and watch it closely for a while.
