Good for you OP for getting the car drivable again. At one point as I recall you thought you had it licked, then ran into a problem with a forgotten Allen wrench possibly damaging belt and/or tensioner. Just curious, what happened after that which allowed you to get it all working again?
I did a timing belt replacement on my VW Rabbit, for some reason not much difficulty to that one. When I did the timing belt job on my Corolla however, followed manuf service manual and supported engine from the top with a home-brew support. I ran into a problem at the end where I couldn’t get the front mount reinstalled into the bracket, engine orientation had shifted slightly. No amount of prying would get it back into alignment. Finally decided to try jacking engine from below, which did the trick.
I think the only reason the shop manual said to support the engine from the top is b/c a shop would want to put the car on a lift to make access to the timing belt area easier. But for a diy’er I’m guessing the better strategy is to only support the engine from below, jack on oil pan, and just do the entire job at ground level.
I don’t recall, what’s the coil issue?
