Rod in Forfar

Hi. I'm looking to this forum as a source of information as I attempt to maintain my 2005 es330. My son and I built a shop for auto repair, complete with a full-sized hoist, so there's no excuse for neglected maintenance except a lack of information. The oil change went fine. Next up is a suspected exhaust leak, as the car is noisier than it usually is. So I'll dig through your files and see what's up. It seems easier to take the Lexus exhaust plumbing apart than my son...
