Lancia integrale - take a 70's designed engine bay, intended for a 1500cc single cam . . jam in a 2 ltr turbo charged twin cam . . . service access wasn't the priority shall we say!
Engine mounts need removing, the engine jacking up and across to get a gap to get the belt through. And then long fingers to get belt cover screws etc back in. And if no-one has slotted the hole in the metal part of the cover, you can't get it off . . - the bolt holding it is too long to come out in situ . . .
If are looking at an integrale, take a look at the inside of the offside front chassis leg . . . a dent means the belt changer resorted to a big lever to push the engine across just enough to get the twisted belt in at some point.
Something similar to my 205 gti track car with a MI16 1.9l 16v engine from a 405 shoehorned into it! It has 2 cambelt tensioners on that you have to get evenly tensioned otherwise it knocks the timing off slightly. I don't bother fitting the covers as its nearly impossible to get them off again!
