Not really "backwards"..... just.... different!

Backwards would be if you lined the cam sprockets up with their marks, took the old belt off, then turned the crank 180 degrees and installed the new belt. Now that would be a biggie. You lined everything up, took the old belt off, didn't move anything, and put the new belt back on - so cams and crank stayed in synch. None of the three components were moved and the number of teeth between each one stayed the same. Nothing changed as far as the engine knew. Nothing backwards about that. There obviously is a point in the rotation sequence where the cam sprockets and marks line up but the dotted line on the belt lines up 180 degrees from where it was first installed on the crank sprocket - otherwise what you did would not work. Or hey - maybe you're just benefiting from the VX's wasted spark ignition! Your #2 is now your #5! Nah just kidding!

Bottom line is you installed the belt with the crank turned 180 degrees from where Isuzu said it should be - but it still works - so no biggie! I doubt they did it one way at the factory and told us to do it another though. Just be glad it lines up both ways!

BTW, sorry for the confusion. I will attempt to clarify using proper Isuzu terminology. The "Alignment Mark on Timing Belt" (aka "dotted line") is suppsed to be lined up with the "Alignment Mark on Crankshaft Timing Pulley" (aka "green tick mark") which is 180 degrees from the "Groove on Crankshaft Pulley" (aka "notch") which is supposed to be lined up with the "Alignment Mark on Oil Pump" (aka "line on oil pump housing").
