I struck gold ...

...no, not black gold, but light green "gold".

I am having to replace the exhaust/intake manifold gasket set,

and I found two bolts were antifreeze flows well. Are there

only two bolts that will do this?

Also, what size and type wrench do you use for that well-

hidden bolt below the carb. Clearance seemed too tight for a

boxed end 9/16" wrench to fit between the intake manifold and

the bolt head, but an open end wrench would not fit either.

Is that bolt a larger size?

Any "secrets" to removing the extreme rear bolt from the

exhaust manifold, without pulling the engine or cutting through

the firewall?

And, should I separate the intake from the exhaust manifolds after

removal from the engine? Or, just not bother with it if I don't have

to do so?

Thank you,

On my p19 the nut I think you are talking about under the intake manifold, I removed with a 9/16 open end wrench, it is a nut on a stud not a bolt.I didn't have much trouble with the rear exhaust nut. As far as separating the two manifolds unless you have a reason its best to leave them together, the bolts break off very easy.

I believe many of the bolts/studs go into the water jacket, so coolant will spill out when removed. Be sure to use some thread sealant when reassembling.

I purchased a 9/16ths cheapo wrench, and ground it down, heated the shank and bent it to have a tool for that particular fastener, and yes several of the ehaust fasteners do thread int the water jackets, sealing them with pipe dope or teflon tape will ususally work.

Thank you all for the words of wisdom.

I will apply them and see what happens next.

Not a secret,but you will find the bolts and nuts are easier to remove if you start the engine and let it reach operating temperature before you try to put a wrench on them.

All good advice, although careful when that engine is warmed up! I just did my exhaust manifold and it was half inch turns for that nut. I do believe I used the small socket size with and extender. A pain, but did work. Should be able to use something in a normal open/socket wrench set, but the grinding and bending idea sounds brilliant!
