Red face 430cid Woes (Part II).

Well here are some pics of my coolant leak source. Again this is the #2 cylinder lower exhaust bolt (passenger side). I used 400 degree High Temp Thread sealer from Permatex.
In 72 hours we will know if it worked.

The 1st pic here was taken with the camera flash off & a flash light trying to illuminated the said lower exhaust bolt.



In the following pics I had the camera flash "on". In the 1st pic, u can see the said bolt just above the steering linkage (That shinny blur running horizontal across the bottom of the pic).






This may be the better pic (I guessed on the aim of the camera). Here I raised the camera above the steering linkage/idler arm. There is a drip of coolant coming out in this picture as well...



After I removed the bolt, there was a VERY steady stream of coolant pouring out. I had to reinstall the bolt and drain the coolant level down to continue. WOW!!

Anyways like I said earlier, Thursday night I'll add the coolant back and cross my fingers.

Let's pray it works guys.

So it sounds like the bolt screws into the water passage inside the block,is this what you are thinking and is this what it should do.
The motor looks great in your car,hope all works out good.

Yes Bob, the bolt must screw into a water passage in the HEAD as "Kultulz" mentioned. I'll keep everyone up to date after I start the car again.....

So, I'm trying to figure out here.

Is this an accidental thing that the one particular bolts has gone into the water jacket?

Or is it that Ford drilled all of the bottom manifold bolts into the water jacket, and then didn't say anything in the 60 430 shop manual about putting sealer on those bolts?

Which do you think -- accident, or on purpose?

Exactly what does the BIRD manual say under Removal And Installation of Exhaust Manifolds In The Car? I can't believe they left this detail out as FORD techs would have been less familiar with the engine than the LINC-MERC techs of the period.

This picture is in the 1959 shop manual it is a 352 would it be the same block as your motor. It looks like the exahust manifold bolts do not go into the water jacket.

Jon: As I told you privately -- your engine looks REALLY great, and I hope that the sealer fixes this problem.

Bob: The 60 shop manual shows the same sectional photo of the 352, but not for the 430. And as Kultulz said, it is a unique engine, so who knows.

Kultulz: The 60 shop manual does not have a specific section on remove/replace the exhaust manifold itself. It is only referred to in the section on head removal (page 1-55).

Under Cylinder Heads:
#5. Coat the mating surfaces of the exhaust manifold with a light film of graphite grease .....

#6. Position the exhaust manifold and heat shield on the cylinder head and install the retaining bolts and tab washers. Tighten the retaining bolts to specifications, working from the center to the ends. Lock the bolts by bending one tab of the washer over a flat on the bolt.

#7. Install the spark plugs.

I wonder if there could have been a later tech bulletin to the shop manual that adressed this situation, or called for sealant on the bolt threads?

I guess that would be like trying to find a needle in a haystack.

The manual you have may be an early edition and left out that step (1959 430's were rare but does not explain the missing information). Surely there would have been a TSB (I have the LINC-MERC 1958 TSB's) or an upgraded manual. Can you imagine the number of 430's that may have went out the door serviced incorrectly?

And while the 352 (FE) and 430 (MEL) are somewhat similiar in appearance and have some parts interchangeability, they are two completely different animals.
