Sigh, the new breather valve did not solve the problem.... or maybe I've got a new problem, don't really know as I never knew where the "old" leakage was...
I've now got bubbling from the bottom of the breather valve housing, when the car is hot and left idling for a while.
My first thought was that the 0 rings were not seated properly. I've re-installed the breather valve 3 times, checked for dirt, cracks or anything that might cause a leak. Can't see anything and the bubbling is always at the same exact spot !
The threads of the bolts holes in the coolant tank seems fine, but is it possble that the leakage is from one of the bolt holes ?? Bubbling is from the side of one of the hole locations. I'm pretty sure the O ring is seated properly. The bolts are tighten to hand tight and then about 1/8 of a turn more or less. The bolts were really loose on the original breather valve.
Any ideas ?? Other than a new coolant tank ??
