I haven't notice any heating or aluminium colour in the oil as of yet. i will however replace the filters and have a closer look.
Meanwhile we did replace the starter as it was filling with oil. After replacing it, we noticed oil was still coming out of it. We then cleaned the breather out as it was clogged solid. Seams to have solved the oil heading to the starter. As far as I know that is when the leaking from the breather started.
I'll have a look for the scavage line to see if it's crushed.
Any idea on how much could possibly cost replacing seals on converter ?
