i don't know much about engines so i was trying to work out what all the bits were. but there are 2 bits i can't work out why they are there. they are:
a hose that goes from the corner of the air filter box to the exhaust manifold heatshield. wtf, what does that do, suck in hot air?! whats the point in that?
and a hose that goes from the cam cover to the intake manifold. whats that for, to suck oil into the cylinders?!
