Kevin,
That's bad luck. Hopefully, you can get the leaks sorted out and hopefully its not the main seal at the rear of the crank - it's a rope seal and if that's leaking, I am told that the crank has to come out.
All exhaust fumes in the cabin seem to be now eliminated. I've had a good opportunity to test is and there's nothing noticeable.
I do however, have to upgrade the seal along the back of the boot lid as the one that is there isn't providing an adequate seal. It is where the lid joins the lower part of the body- where the locking mechanism is located.
There is a story (a brief history thereof and a brief description of the refurbishment on this 410 published in the current BOCA Club Express magazine.
