I pulled my distributor today thinking I could get it back in without having to set the timing. Dumb move I know.

But now I gotta set the timing but can't find the marks where to shoot my light at. My engine is so filthy I can't see anything. And I know in theory how to set TDC for the 1st cylinder. But I don't know which pulley to turn for the crankshaft.

Plus I've never set the timing before, ever. I do have a factory repair manual so that help but it's not too clear.

Please help ASAP!!! This is my primary vehicle and I drive it everyday. I have to take the bus tomorrow. I need this done quick. Pics if you can.
