Tappets need shims

Question : DO the tappets on a 1998 Toyota Harrier 2.21 require regular adjustment? The engine on my vehicle rattles noisily but my mechanic tells me that there is nothing that can be done to silence the engine, save a complete overhaul.

Answer : THE tappets on a Toyota Harrier 2.21 can be adjusted to quieten the engine if, indeed, the tappets were making the noise in the first place.

However, unlike conventional tappets, adjustment is done by replacing shims, and not by a "nut and screw" adjustment.

Your mechanic would first have to measure the valve clearance, then remove and measure the thickness of the shims on each respective valve. The thickness of the replacement shim is then calculated in order to bring the tappet clearances to specification.

All this work has to be carried out on a cold engine so this may mean that your vehicle will be have to be off the road for at least 24 hours.
