Normally, you won’t need to make any interventions on the timing chain of a Toyota VVTi engine, but if for certain reasons you have to, here’s a tutorial on how to do it.
The timing chain cover is found right at the front of the engine, located just behind the accessory belt and different pulleys. As you probably imagine, you have a lot of parts to remove before reaching it, so you’ll need a complete set of sockets, a ratchet, different screwdrivers and rubber gloves. Here are some steps on how to perform the job:
Now you’ll need to remove the engine’s mounting harness, so if the engine is still in the vehicle, you need to support its weight with a jack
Remove the timing chain tightener
Finally, remove all the bolts fixing the timing chain cover to the engine block
Use something to pry it open (you might need a hammer here) and you are done.
