I'm running Bryon's 20% and OS A5s.

I should hope it's not wear, cause the engine has just over 1/2 gallon through it. As for an air leak, I wouldn't know how to figure it out.

Unfortunately, the only day I'll be in Northville is early sunday, since we're bouncing straight up to Traverse City since I won't be racing.

As for hot temps...well, it is Tennessee. Hot and high humidity.

How would I find any air leaks. I'd hope that a new engine wouldn't do it, but...
