I started my 1uz tonight the same as I always do.
The only difference is that today is probably the coldest day I have ever started the car (about 15degC), but I don't know if that is relevant.
Anyway, I had this weird clack sound.
It was very consistant.
clack clack clack clack pause clack clack pause for 2 secs, and then started again.
Would have done this for a good few mins.
Stopped the car, took off the accessories belt, tried it again, did it, so its not the p/s, alt, fan, or any idler pulleys.
This leaves the 2 cams, the crank, waterpump, and any idler bearings on the timing belt.
Its much louder in the valley at the front (sound coming up the front covers), so to me it sounds like the waterpump.
I drove the car home (8km), and the temp was fine, so the water pump is still working.
The sound had also stopped by the time I got home.
Any have any ideas?
My money is on the water pump
