94 Z34 project

[rharlow]

So, I just bought a 94 Z34 for my daughter. It seems well taken care of, but it is 12 years old. So, I'm planning on doing the timing belt this summer, and would like to know what else I should do as preventative maintenance, while I've got everything apart. I plan on replacing the belt, tensioner pulley, idler pullies and tensioner actuator. Should I replace alternator while I'm at it, or would I still need to do this from underneath the car? Also, waterpump? Intake gasket? Anyhting else. I also heard that there is some distributor hole plug that tends to leak oil? Not sure about this one. Anyway, thanks for any input!

Sounds like have a pretty good plan with the belt and pulleys. And since you will have the upper intake off to do the timing belt, I would replace the lower intake gasket. The plus side to this is you can inspect that distributor block off gasket that always leaks. The block off is under the lower intake but it can't be fully removed with taking the head off. But it can be pulled up enough to put your favorite brand of sealer in there. As for the alternator, that is stuffed down between the rear cylinder head and the firewall. You have to get the alt. out from underneath the car. The alternator will probably be ok unless your daughter wants a huge stereo with big amplifiers, or wants to go splashing in deep puddles alot. The water pump is not something I would replace unless it has to be done. It's pretty easy to get to if something should happen. This isn't a real weak link with these engines. Hope this helps!
