A customer called recently to inquire about pricing. Apparently another repair shop reported that the rear main seal of his E90 BMW 328xi was leaking profusely, which they had noted while repairing a steering fluid leak. The owner wanted to hold off on the additional repair until he had more information.

Because a rear main seal leak on that car — with less than 100,000 miles — would be out of the norm, so I asked if the engine had been fully washed and de-greased in order to pinpoint and confirm the source of the leak. It had not. . . .
