Toyota Corolla-1997; 88,000 miles; 1.6L-4FE engine: A couple of weeks back, I got the tappet valve seals replaced due to mild smoke from the exhaust at high acceleration. Since then, the engine (tappet) has become noisy. There is no noise at all when the engine is cold. The noise comes on as soon as the engine is warmed up and remains. The seals were replaced by pressurising each cylinder with compressed air, without removing the head. At that time, engine oil & filter was also replaced. The workshop replaced the engine oil again. No use. Then they added " RESTORE" - engine oil additive. No use. The noise is worrying. It has been a very smooth car all along. What should I do next?
