As I was working on my new to me Z over the weekend, I ended up taking the intake manifold off in order to drill/mill the bolt that is broken in it that attaches the carbs. I decided while I’m at it, it’s an easy and cheap task to replace the intake/exhaust gasket and get new studs/bolts that go into the head. Unfortunately the head itself has what looks like 2 (now 3) broken studs inside of it, and the exhaust manifold is stuck on.
To help get the exhaust manifold off and make sure all of the thread in the head itself are clear, I have been considering pulling the engine out. Then one thing leads to another and I start thinking maybe I should just replace all the gaskets, down the rabbit hole we go, i thought maybe I better just do the rings and bearings too. But, I thought I’d check the forums for opinions. I hate to spend the extra money and time to do a full tear down if it was just done 5k miles ago. I was told when i bought the car the the engine was the best part of the car. Should I just treat it as if it has 200k+ miles and do a full rebuild?
I work with the guy i bought it from, so i'm going to ask him today if he has any idea the last time a rebuild was done. But, it's likely he doesn't know. The car itself hasn't been on the road without the help of a trailer since 05'.
What do you guys think? Rebuild, or nah?
Don't say swap, I'll be doing one eventually. But, i'll only swap for something more modern than an L series and i don't currently have the funds for it.
