The timeing belt was removed to replace the tensioner and idler bearing. I am concerned about placing it back on and the marks not being in line. How do I get it on and assure the marks are in place?

    Didn't you aligned the marks before you removed the timing belt, or you did set the marks perfectly, but now when you try to install the belt is off maybe a tooth?
    Let us know and don't turn the cams or crank shaft before you do!!!!!

    I didn't know to align the marks before removing the belt. How do I get the marks to the correct alignment with the belt off. As I was cleaning I bumped one of them and now they are all out of alignment. please help......

    Is there any way that I could call you?

    Oooops! That is a HUGE problem now. This is an interference engine.
    Please answer in order:
    1, I assume you didn't mark them either?
    2, So you have no idea how the cams and crank pulleys where lined up before you removed them?
    3, Since you bumped into one of them, do you know how much they moved at all?
    Only 1-2 tooth? or more?

    All the marks on the cams and crank are supposed to be at 12 o'clock position.
    The upper cams should have a single mark at 12 o'clock, which lines up with a notch on the cover and a double mark at 6 o'clock, which lines up with the lower cam's 12 o'clock double marks. The lower cams also have an other mark which should lines up with a notch (left cam has it at 9 o'clock position, the right at 3 o'clock position.

    Anyway, I'd strongly suggest NOT TO DO ANYTHING, because you can damaged the engine. There might be a way to analyze the positions of the shafts and based on that an expert (actually 2) technician could move the cams and crank slowly in synchrony with the correct rate. But believe, me it's not easy at all, and even if they volunteer to do it, I bet they won't (can't) guarantee anything at this point.
    Unfortunately it's a lesson to you, not to do any repair (especially a major one) without first reading manuals and consulting with the experts.
    I could give you a number, but I'm outside of the US for a while now and I'm not sure if you want to pay for $$$ long distance call.
