This is Stag related as it’s the engine in mine but its not a Triumph one.
Had a slight issue with my engine yesterday. The engine itself is turbocharged and dry slumped. When I started it it sounded like one of the idlers or alternator is seized, as it was squealing like a scalded pig. Far worse than just a belt slipping, but something was slipping, it was definitely not a metallic noise.
Obviously l switch the engine off straight away, assumed it was one of the idlers. Tried the engine again to locate the noise, it was coming somewhere from the front, but I couldn’t locate it. Checked all the idlers which seemed to be free.
marked the alternator, idlers and belts with chalk, put the car in gear and pushed it forward and everything seem to move okay. All moved freely with the belt.
Cautiously I tried the engine again but the noise had gone. Now the only thing I thought it could be was the idler that drives the water pump from the cam belt had seized.
Now I do have an electronic water-pump, while the car was ticking over I did notice that a couple of the temperature gauges were higher than normal. where as two of them were a lot lower. The car got up to temperature, didn’t overheat but this also made me think that somehow the internal car water pump isn’t spinning.
If the impeller is not turning, will the idler still be working to keep the cam belt in tension. I am in the process of ordering a new cam belt kit, just to be on the safe side. But to change the cam belt I think the engine has got to come out, and all the manifolds, turbo, pumps, coolers and pipes taken off to get to it. Which isn’t going to be the normal 4hr job of replacing the belt.
Has anyone had this happen and is it a clear sign the cam belt is a bout to fail.
