Okay, so I had an oil leak from my distributor gasket, so I decided to change it. Well I changed it out, put the distributor back on, and now it won't fire. The first time when I changed my intake gasket, I put the distributor back on and it worked just fine. Well I've been reading about finding top dead center, but I have no idea how, or what exactly is required to find it. I read that I was supposed to mark the locations before taking the distributor off, but it's way too late for that now Can someone explain to me what the easiest and quickest way to get the timing straightened out so I can get it running again? I feel really dumb that I did this, but it worked fine the last time I did it, but I guess I just got lucky. Any help would be greatly appreciated. Thank you all very much for your help in advance.
