Guest wheelsport Posted December 22, 2014 Share Posted December 22, 2014 My '89 TC has a rattle around the timing belt area. It seems come and go mostly on startup. The timing belt cover was warped and the belt rubbed on the cover. I heated the cover in the area where it rubbed and straightened it fixing that noise problem. I put the stethescope on the fuel regulator, which is in the same area, and hear a similar sound. Any ideas as to what's causing the noise? Maybe timing belt adjusting idler?

You could try adjusting the belt tension using the proper tensioning tool. No slack is exactly correct, tension on belt is too much! Link to comment Share on other sites More sharing options...
