Re: C-Drive Oil drain - Alternative
Thanks Craig.toggle quoted messageShow quoted text
So it’s entirely possible we had a small ingress of seawater while the seals “seated,” and that settles at the lowest point in the system, certainly not in the reservoir/expansion tank (and thus not seen). The key for me going forward, it would seem, would be to keep an eye on the volume of the reserve, if it increases...the ingress likely continues.
I’m trying to think of the tank height relative to waterline, I think it’s slightly above, which if the densities of these two fluids were the same would result in relative positive pressure of the system compared to the seawater. Is the key to the ingress problem that the oil is significantly less dense and so even with the column above the waterline, there remains a relative tendency of ingress vs egress? Does anyone ever “loose oil?”
This should be at the crux of the seal orientation debate I would think.
Thankfully, still lubricious,
