The most common cause of massive oil leaks on this car is a failure of the front balancer shaft seal. You will need to replaced the timing belts and the seals under the timing cover

I need instructions on how to do this. Can you please email them to me?

Ok, I will. Have you done a timing belt before?

This engine also has an extra belt for the balancer shafts.

Customer: replied 5 years ago.
Is this all the instructions including changing the oil pump?
Expert:  John G. replied 5 years ago.

Do you mean water pump?

Once its all apart the water pump is jut 4 bolts and its off

Customer: replied 5 years ago.
If it is the water pump, why is oil leaking out as fast as I put it in?
Expert:  John G. replied 5 years ago.

The front balancer shaft seal has popped out. look at the image of the front shaft. You take that pulley off and remove the old seal. Then install a new one.

Most people replace the water pump as long as the timing belts are off, but if ours isnt that old you can leave it alone

Customer: replied 5 years ago.
So if I do all of this, will the oil stop coming out.?
Expert:  John G. replied 5 years ago.

When you remove the timing cover you will see that the seals for the front balancer is no longer in the block, it has popped out and is spinning around with the front balacer shaft.

There is a huge opening where the seal should be and oil comes out rapidly.

The timing belt should be replaced because the oil will cause it to break before it should
