Just purchased a 1998 Rav 4 2.0GX Automatic for my wife, but the valve train appears to be extremely niosy.
The mileage is 101, 000.
When purchased the oil had not been changed for some time, so this was changed, the engine flushed and a valve lifter additive was also added to the oil.
The niose seems to be very loud when the engine starts from cold and the valve clearances are all near the top end of the range, but within it, there is no visible deterioration on the cam lobes.
As the engine warms up the noise then sounds like it could be just one valve/lifter, but is persistent and quite loud, although not always noticeable when inside the car and driving.
I didn't expect a Toyota Engine to be this noisy, has anyone else had a similar experience, or can anyone point me in the direction of a cure?
