Ecotec engine timing marks - 2005 Pontiac Sunfire

what engine is fitted? did you get a new timing belt adjuster. did you set it to new and not old. ecotec timing marks are on the cover and inside the cam cover. lower timing marks are on the pulley and on the crank. this should line up with the sump case marking on crank and the pin on the engine on the pulley. you need to rotoa the engine at lest 3 times to check the position of the time. also if you have had the cam sprockets off are they on the right ones as this would make timing out. both cameras are set different, there should be markings on the cmes to say inlet and exhaust. same on the cogs. when adjusting the time rotte engine by hand 3 times and if out on the timing and out of new adjust again until each time you rotate the engine it all lines up. adjustment is best done with the pull off. rota adjuster are anticlockwise to adjust dont do this clockwise, as it will move over time away from the stop pin and cause damage to the engine or timing adjuster.

Google the question, there are several returns.

Time it how ? timing marks on cam an crank ,timing chain ? There is no other way !

As it is easy to ruin your engine if you mess this up, buy a shop manual which will tell all steps to do the job correctly.

Man, that's a hard one for me, but what I would try, is go to an auto part, see if they would let you see one, so you can mark yours, I'am sure they will let you, good luck, sorry could not help much, just an idea.

on the gears behind the timing cover

what model ?? 8 valve?? 16 valve?? petrol ?? diesel?? .Remove np one spàrk plug and put a long thin screwdriver into hole and turn engine till the piston is at the top and then look for timing marks ,if you still cant see them paint the cam gear .with a couple of spots of white paint ,the lower crank mark it when the keyway points at the top of bottom of the engine.If i remember rightly these opel engines have the timing mark as a white line on the belt .But mark it anyway and always rotate the engine 360% by hand to make sure the valves clear and you have it right
