hey again!!! :D i am almost ready to start my truck(i think). all i have to do is get the ignition switch hooked up and set it to T.D.C. and pop in the distributor and that should be it. one thing i want to know though is about the vacum lines and witch ones i am supposed to hook up and to where? i know the ones on the pass side go the the vac advance and the air ccleaner but what about the ones on the other side? and also setting it to TDC. it should be like a v8 rite? just pull #1 cyl. spark plug and bump untill the compression stroke and then set the distributor with the vac advance pointing twards the rear and the rotor pointing at #1 cyl? well i hope thats how it works! anymore advice would be great. thanks.

It is much easier than a V8. Grab the fan and turn the motor over by hand, a socket on the crank pulley bolt works too. Line up the timing mark on the crank pulley with 0 on the timing cover marker deal. This gets you #1 or #4 at TDC. If both valves are closed (rockers will be just slightly loose) on #1, then you have #1. Same goes for #4.

If you are just doing this to put in the distributor though, you don't need to worry about any of that. Drop it in the hole and it will go in right. The shaft end fits into a slot and is offset to one side so it can only go in one way, the right way. Then line up the vac advance on the disti so it points just a little in towards the motor from straight back and it should be close enough to get it to fire up. If the timing is off then, the cam gear would have to be on the timing chain wrong, I've seen them on backwards a time or two.

The vac lines go something like this. The front most outboard on goes to the disti, and the other outboard side one goes to the EGR thermal valve in the intake and then to the EGR valve (or BPD). On the inboard side, one of them looks different, thicker wall smaller hole, that one goes to the valve cover. The others, lets see one goes to the air cleaner, tees off and then hits the two deals on the air cleaner. Another goes over to the vac switching valve for the smog pump. Seems like I'm missing one too. There should be a vac diagram on your hood, but often they are painted over or gone, or for the wrong year. Worth looking if you have not though to though.
