This is the valve train of a 2003 Toyota RAV4 1AZ-FE engine. We had the car since new and I used Valvoline conventional for every single oil change, with 5k OCI. Every valve clearance is still within specs (original shims). I was only able to measure two of the cam lobes with my micrometer, since there was not enough room to measure all the lobes with the cam still inside the engine. The two lobes I measured were still within specs. What do you think?
