Hi everyone new to the escort, I bought a 2002 zx2 a week ago and have already done some work. I changed the valve cover gasket and noticed the timing belt was cracked very bad so I bought a gates kit and replaced it with new belt and pullys, this morning on the way to work the timing idler pulley bolt snap off flush with the block and the car quit. I then extracted the broken bolt and replaced the idler pulley with a new one and torqued to 35 foot pounds and my chitons manual says, the first 5 minutes on the way home everything was working great then I notice it started to tick under load but with the clutch all the way in and Rpms dropped or sitting at a stop light the noise went away, then would come right back as I started driving. From what I can tell without out pulling everything apart again it sounds like it's coming from middle of the engine under the valve cover over the exhaust cam. Also I've read some stuff online about having to reset the vct and the belt slips but it didn't say anything about that in my chiltons manual. Any help will be greatly apreciated car also has 89000 miles on it.
