the Isuzu 2.2L the valves are not at a angel to the piston. they have rockers that bend or push-rods that bend when the valves strike the pistons....
sorta the lesser of two evils
so even though its a interference engine, with 21 to 1 comp.
in the event of timing failure....head removal is seldom ever needed.
(i know of no one that has had too)
the engine was made bolth ways, belt and gear timing.
on road is belt, off road is gear.
and no you would not want to use a gear model on the high-way.
there de rated about 30/50% for running water pumps, gen sets, welders ECT ECT
and have much lower max rpms.
