Disadvantages of the Toyota 22R engine
The carburetor’s competent setting is the primary challenge for the owners;
The distributor is more concerned about ignition system issues than anything else.
The timing chain frequently stretches and begins to make noise during a run of 150–200 thousand kilometers;
There are no hydraulic lifters in this motor, and the valve clearances need to be adjusted on a regular basis. Other than that, it is a very dependable motor with a resource of roughly half a million kilometers.
