Rattle from front of engine on slight acceleration and deceleration.

Quick test to rule out PS pump.

Take off the v belts, start the car, see if it still does it.

Don't run the car very long- you have no water pump now- but if it's not
quiet, I stand by my initial diagnosis....

Sorry to report back so late. I did the tests as suggested above but noise didn't change. I decided to swap the timing belt, tensioner and water pump. Something I noticed when I removed the timing belt cover was the contact and groove formed from the belt rubbing on the inside. Is this normal? What prevents the belt from moving in and out on the cam and crank ?

I think would be the most logical source of the noise. On slight acceleration, engine speed increasing.

Another update. Definitely was the tensioner! Holy crap I got lucky. Thank you R3V!!!

It was wobbly and I grabbed it to spin and checked for noise. It fell off in my hand.

Got the same noise out of mine.

Head was rebuilt/timing belt, tensioner, water pump, everything was done about 3,000mi ago. At the dealership. Would a tensioner die that fast?

I got mine replaced and its fixed. Went with the Gates racing belt and all new parts from Ireland Engineering

When I had my head gasket done it was supposed to be replaced. It only 6k miles when mine fell apart. Looks like the bearings or race seized and sheared itself.
