so here's the story. my crank pulley separated on me, and I was trying to install a new fluidampr. In the process of checking the timing components, we noticed that the idler pulley had significant play - the new belt was put on 5k miles ago.
we decided since we had the cover off to replace it. We marked the belt in all of the right places, and loosened tension on the timing belt to get the idler on. we got the auto tensioner back on, it was just around 4.5mm - and seemed close enough to spec acorrding to the vfaq. all of the timing marks lined up accross the board, so we put it back together with the new idler and fluidampr.
we then tried to start it up, and the car kind of puttered a bit, and had figured it was because it was the first time the car had been started since October, so I continued to try to start it. after the third try, out came a loud ass backfire. Now when I try to start it - it does't sound like it normally does - almost like it has no compression. we checked the timing marks, everything still lines up on the cams, and on the crank pulley's notch that lines up on the timing cover.
Right now we are thinking that maybe the belt may have jumped a tooth. would this cause the car not to start? am I looking at possible bent valves because of the backfire? could it be bad gas - since it was sitting for nearly 9 months?
we did try to crank the motor by hand afterwards and we were able to feel the compression cycles while turning it - is it true that if you can turn the engine by hand, and feel the compression, that could mean that the valves and pistons are still ok?
we are going to try to a compression test next week to see what's going on. we are thinking maybe a bad injector, but something tells me we did something wrong with timing.
any thoughts?
