So yesterday I changed my cam seals and crank seal. While I was in there I also fitted a new cambelt, 2x smooth idlers, toothed idler and small smooth idlers. Set the timing and put it all back together with new coolant.
All was well, started her up and timing was sweet, filled and burped cooling system then took for a ~20km drive. Drive was fine.
After the drive there was a bit of steam rising from bellow radiator cap (near the turbo) figured it was just spilled coolant on the hot exhaust, all good. But there was also a very slight burning rubber smell from passenger side of motor. I pulled off the passenger side timing cover and noticed what appears to be rubber deposits on the small smooth idler.
Inside passengers timing cover looking towards crank.
I checked and I can still spin this idler, there is a little friction from the belt but it isn't seized or anything.
Water pump still smooth no deposites.
Anyone got any ideas of what could be wrong here? or is this normal wear in for a new belt. As I said I have only driven ~20km.
Also how much play should be in the belt once the tensioner pin has been released?
Thanks
