Removing Intake manifold

[OhDearAudrey]

Plan on removing My intake manifold soon to put in my MSA headers, anyone who has done it before know what special tools i might need to make the job easier?

Soak all studs and nuts with PB Blaster for a day. That'll save you a ton o'grief if they're frozen....

No special tools. just some open and closed end wrenches will do the trick. I would recommend getting the stud kit for the intake/exhaust. I put one in mine when I swapped out my carbs. Really made things easy and you know you have good bolts going back in.

Also, make sure you clean out the threads in the head when you have everything off. It is a horribly boring job and it will murder your fingers, but having clean threads to put bolts/studs in will make all the difference. Plus, dirty threads negatively effects the running torque, meaning you may not get the proper preload on the system when you put it all back together.

Other than that, patience. It is not hard, but it is time consuming. Take a couple of hours to properly clean off the sealing surface of all the parts. Cleanliness is key to a good seal. Also read up on the proper torque specs of your manifold/header.

Good luck, and take Franks words to heart. Soak those bolts before you put a wrench to them. Do everything you can to make those things come out easy. The last thing we want to hear is you stripped your head or broke a bolt.

Take your time and you will be fine. Remember, working on these cars is suppose to be fun, not aggravation.

Are open ended wrenches easier then a socket wrench?

Some nuts require open/box end, others you can get with a ratchet...

A universal joint for the socket set is nice to have, but isn't a requirement. you can get to all the bolts/nuts with either a socket or a box end wrench.

My wife bought me a set of Stanley ratchet box end wrenches, this made it easier for me than the standard box end wrench. As everyone stated soak the nuts and bolts with PB Blaster or WD40/ take your time and get the stud kit from MSA :classic:

[OhDearAudrey]

Anyone happen to know the size of the bolts, or wrenches ill need, so i can go get them.

[d240zx2]

Just get a set of sockets (metric) that run from about 6mm up through 17mm and combo wrenches in the same sizes. No need to get onesy-twosies as you'll need 'em all at some point in your Z career....

Well, if you're gonna buy tools, make sure to get 6-point sockets and box ends. Your nuts and knuckles will thank you.

This is almost the same subject. Any hints for removing air injection tubes from intake manifold? Im getting rid of the smog equipment and only thing between happines and total frustration is that darn tube. I've tried CRC Rost Flash (instant freeze anti-rust removal spray) and i've tried torching them but they just wont move..

That's a tough problem, Koalia. You might find PB Blaster effective after a few days of soaking, but methinks having a machine shop drill the tubes and retaining nuts would be your best and safest bet. Even after a couple of years, those nuts will lock in like they've been welded, and after nearly 40 years, well, they might as well been cast together.
