I bought this car at 85k, now has 250 k, and have never adjusted the valves. Engine run strong and gets great mileage. Do I really need to adjust the valves?
RepairPal Certified shops can diagnose and repair your 1999 Toyota Camry. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
According to the "book" valves should be adjusted every 30000 miles, so I would guess hydraulics. No they are not noisy.
