I own a 1975 280 z which has an exhaust manifold leak. Does any one have experience removing this part? I have a shop manuel but very little info is given and nothing describing its removal. Any advice is appreciated.
If you aren't experienced doing it, I would suggest for the first time you seek out a mechanic. Here's why:
It's not that difficult PER SE to remove, but you've got a real potential to BREAK one or more of the mounting bolts if you are inexperienced at removing them. And, there isn't much room to work, so if you don't have a good assortment of socket wrenches and extensions, then you will get frustrated real fast.
A pro can remove on in about an hour.
This might be a good time to add a header exhaust since they cost less than an OEM exhaust manifold. You'll also have to remove your Fuel injection system because they share the same manifold gasket.
