Wow! Factory service tools. You'll have to let us know how they work. I don't know why we have heard of so many of the little bolts coming loose. The interesting thing to me is that many have reported oil leaks from the carrier, but only one that I can recall reported a loss of coolant. That cover seals both. Maybe it is just that the oil is under higher pressure and will be the first to seep through.

Have you been able to find replacements for the little plastic retainers? I would think the silicone would do just fine.
