Alright so I've got everything back in the car after a week of agony and torture. Didn't even have the injectors for half the time. Anyway I'm about done, but I can't find my one bolt. There's that one pulley that goes on the front of the head. It's connected by 2 bolts and a stud, the fuel rail also attaches around it and whatnot. Anyway the big long bolt that goes through the middle of that pulley I can't find and might need to get a new one. First off if I run the car without that bolt, is that a bad thing? Second, what size is the bolt and how long is it? Would I be able to get a new one from like Home Depot or something?

As far as injectors go. I have one 280ZX injector and 5 300ZX injectors in my car. Haven't tried it out yet. The plastic like piece on the tip of one of the 300ZX injectors broke off so I assumed I couldn't use it and put on a 280ZX injectors I knew didn't leak.

Thanks for your help guys.

 

My advice... Don't go to a home improvement store, to get car parts... go to a car parts store. That bolt should be a regular size 12mm head. Hopefully you have spares by now. If not, just stick a phillips screwdriver, or similar item in the hole & measure the depth... then go buy one w/ the same threads as the other 2 bolts

 

Leaving that bolt out wont cause any problems with the pulley but it will allow oil being thrown off the timing chain to leak out of the engine slowly. I accidently left that bolt out awhile back and then was plagued by the oil leak for several months before i realized where it was coming from. Also, if that bolt is not tightened properly it will sometimes leak a little oil.

 

Gone to 2 stores so far. Neither of them had a 12mm even near 3inches long. Luckily I think I have a couple left that are the same size, that came from the 300ZX.
