I have an 86 Honda Accord with a carbureted 4 cylinder engine. The head was replaced some time ago by a fly-by-night repair shop (that has now flown). The engine has developed a manifold leak, and I see the problem is missing nut on two of the studs that come out from the head and through the bottom of the intake manifold.
I can see the studs through the gaps between the intake tubes on the manifold. I'm pretty sure the fly-boys didn't put nuts on them because they are impossible to get to with a regular straight 12 mm wrench.
Is there a special tool or wrench that should be used to put the nuts on these studs? It's pretty tight. It would have to go between, and then wrap around the bottom of, the intake manifold tubes, yet still provide enough motion on each turn to get the nut moved far enough for the next turn.
Also, how do you go about properly torquing these intake manifold nuts?

Most shops will bolt up both the intake and exhaust manifolds to the head before putting it back on the block. However, this information doesn't apply in your case since the head has already been reinstalled. The trick is to use a couple of different wrenches and go at it from the bottom. It's not easy, but it can be done. Having the car up on a lift such that you can stand under it will make the job easier but that's not absolutely necessary. Here are some links to some wrenches that may make this job manageable...
I would definitely go from underneath. You should be able to tighten it by hand. I don't think these are very tight - about the same as a spark plug, I believe, but you can look it up in a library if you don't want to buy a manual or maybe a dealer would be nice enough to tell you. It wouldn't be a bad idea to have a machine shop check it for warping but you probably don't want to rip it out. If it still leaks when it's tight it's probably warped and you can have it machined to fix that.
