No problem. Be aware that it's also not a green flag... the gearbox could well be shagged and ready to snap a tooth. You have to factor that in when buying an older car.
I have a couple of these... large one in the car, smaller one on a trailer. https://gpslivetrack.co.nz/gps-trackers/battery-powered-gps-trackers/
$15+gst per month each as well, which kinda sux but there are a lot of features you get for that and don't have to worry about sim cards etc.
If you lose the MAF and put a catch can in... the intake pipe suddenly becomes very simple. A straight pipe (under the manifold) with a bend. Connect it to the standard airbox,
or to a cold air intake as you said.
yeah they are important... once you find one, make sure the spacing is correct... too big of a gap and it won't prevent a jump... too small and heat builds up and damages the belt.
Usually you would have a belt guard above the crank pulley to prevent the belt from jumping... is it just off for checking the position of the belt, or is it missing?
I don't disagree with any of that... I just don't think that noise would be caused by the belt being out by one tooth. I certainly WOULD be changing the belt, tensioner, all the idlers and water pump though.
The timing belt being off by one tooth with not make a noise... the engine just won't run quite right.
But the exhaust wheel fouling on the intake wheel will likely cause a bit of a noise... as in the last picture.
