SO YEAH , WHERE does it seep from AFTER you put it on ??
Well, I don't discount the possibility of seepage after installation. It is a risk with modifications like this. Problem was, if you recall, that the oil pan was going to "groove the salt" in the unmodified condition. So, something
HAD to be done . . . . . . I'll take my chances that any defects after the fact will be minimal. If they are not, we do not run. Simple as that. But I'll bet the "over" on this issue.
BUT, anyone who has worked on early Cosworths or, say, Jaguar V-12's, is familiar with "seepage", both oil and water, from unmodified, stock castings. British alloy castings were notorious for these defects. In fact, in both of the Coventry Climax books I've read, Walter Hassan describes various methods used by the Prototype department to seal up expensive castings for their F1 race engines. Cosworth had the same issues, which prompted them to invent and patent a casting process engineered to eliminate casting porosity.
When I was building Jag V-12 based race engines 30 odd years ago, I had to establish a protocol for sealing
ALL the bare casting with silicon silicate
PRIOR to any machine work or assembly. This was to prevent the seepage from the stock castings, which had been "accepted" by the previous builder and the team. Unfortunately, this cost the team a couple of engines. The situation required "correction".
I seem to recall that a lot of bike engine powered vehicles have to deal with "seepage", both oil and water, as a matter of course. We'll see where we end up on that spectrum.
