Got a prob with my neo 25, started it up and it made a weird as hell noise. traced it down to the timing area and took the cover off and found the belt to be walking forward all the way and rubbing on the cover.

recently had a new water pump and timing belt on. tensioner and idler new also. What could be the issue? im suspecting bent idler stud at this stage causing idler to be on an angle.

Just backing up what others have said already, check that everything is straight and in line. Also check the flanges on the crank sprocket/pulley are hard up against the sides of it. All timing belts will track to one side or the other due to the way they are manufactured, the flanges are their to keep them from tracking off. If one of the pulleys or idlers etc are misaligned then it will force the belt to track incorrectly. If part of the belt is running over the edge of a pulley do not drive it as the belt could become damaged and fail.

Good Luck.

      What should I do next to hold the head on

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
