If the leak is under the timing belt cover i would inspect further and make sure it is not coming from the water pump and if so i could recommend replacing the water pump because the sealer will more than likely not help your issue

It has a timing chain for both pushrod and DOHC engines! Have system pressure tested to FIND your leak.
