Couple of Stupid Questions??

[ZauggIt1]

Ok, i know this is going to sound stupid but, i cant figure this out for the life of me. I have had my 7mgte motor out of the car for about 8 months now. I cant remember alot of this stuff...... I know, i screwed up when i pulled it, but i was anxious to get it done, now im 8 months, $5,000 and its not running, YET. So, from what i think, the pcv valve goes in the center of the head, on the back plug right?? Well, what will actually happen if i just put a regular plug in there and eliminate the pcv valve all together?? Another one is, i cant quite ready my door sticker, so how do i actually find out if i have a LSD rear end? and what trans? Its a 87 turbo manual, is it the r154 no matter what?? I dont, know, thats why im asking you guys. So anyways, all help is deeply appreciated. One more thing, does anyone have a good picture of all the vacuum lines, i am dredding that day to come. So many of them.. THanks again guy, i love this site/forum..
