FWIW, I had a lot of leakage and seepage going on with mine. I have tackled all the leaks aside from the sweating vacuum pump (have the BMP gasket kit and I'll install it next oil change). That reinforcement plate (aka drip tray) has been off more times than I can count. I've reused the bolts, but I don't like it. They are TTY. I have a new set which I plan to install after my next oil change and leak repair.
