Post subject:  Manifold removal - Underside retaining nuts
I'm setting up to remove a cracked exhaust manifold. I'm looking for any good tips on accessing and removing the underside retaining nuts. It doesn't appear there's a lot of room for getting any leverage.

I'm hoping to avoid breaking off the nuts or bolts or at least minimize the number. I plan to take my time and use plenty of PB-Blaster.

Any other words of experience is appreciated. I did check out the manifold replacement article posted earlier.

Thanks,

TJ

I have a 12" long 3/8" extension and a thin swivel 1/2" socket that works really well. The only studs I have ever had break off were the end ones.

The hardest part on reassembly will be getting the bottom washer/nut back in under the choke pocket. I have a long pair of needle nose that work pretty well, and have slid the washer/nut in on a long, thin screwdriver too.

Make sure to leave the nuts/bolts that connect the manifolds together loose until you have all the manifold mounting nuts snugged up or you will have a leak between the manifolds. :D

Or put a long piece of thread or string through the washer, grab the ends of the string so the washer hangs from it, and lower the washer down from the top with one hand while you guide it onto the stud with the other.

I take a die grinder and remove all the casting flash on the exh manifold. It gives a tiny bit more visability to see what you doing.

I have a set of Harbor Freight "wobble" extensions that seem to work for those pretty good. They are undercut a bit, right near the "seat" that the socket bottoms on, to allow the socket to wobble around about 6* when attached to the extension.

Great info. I appreciate the input. I'm on my way out the door to pick up the extensions and socket adapters. It's good to know about the washer issue on re-assembly. I'll let you know how it turns out.

One more thing that I have used for years on any nut/washer reassembly is contact cement them together and sometimes even a dab to hold em in the socket.It works and you can clean the socket out later.One less thing to drop and find or atleast they should be together when you do locate the little buggers 8)
