I had the same problem for about a year. Finally my water pump locked up, which is driven by the timing belt. In the process of replacing it I realized the bearing to my timing belt pulley had gone bad. I replaced water pump, timing belt, tensioner, and both pulleys. The terrible noise I couldn't figure out is now gone. If possible I would recommend replacing all of these. If you do it yourself you will need a particular tool to set the tensioner pulley. The part # for the tool is MD998767. I found it online for about $30. Simple to use. It is made to fit into the 2 holes on the tensioner pulley. With the tensioner released the bolt to the pulley should be hand tight. Using the tool apply 38 in. lbs. of tension against the belt. While holding the tension against the belt torque the pulley bolt to 35 ft. lbs. The In. Lbs. and Ft. Lbs. I found on another forum. They are what I used and I haven't had any problems. Hope this helps.

Glad to hear it worked for you and thanks for the info. This is the reason why there is a schedule to change these things, to prevent breakdowns. Luckily you had a freewheeling engine. If this was interference you'd have needed a new head. Good luck with the car now that you've got it running.

Just to add, it is also a good idea to replace the crank and cam seals while your in there. They usually become hard and leak with age and mileage. Doesn't make sense to do the whole job over again because you ended up with leaky seals later on.
