63 engine over spray patterns

Re: 63 engine over spray patterns

Alan and JD have been talking about the distributor oil line finish. Why don't you be one of the first guys to have it correct since you like having fun and getting the details right.
The line should be copper plated steel. Same process as the oil gauge line.
My 63, the LWC though has the wrong distr oil line.
No one has this line so you are on your own.

I have a magnetic, copper coated oil line ready for installation. I persume that will pass??? I got it from Corvette Central...

Re: 63 engine over spray patterns

Rob -

1. The clutch cross shaft stud is natural/unpainted - it was installed at St. Louis.

2. The only water pump bolt with a lock washer is the one attaching the alternator adjusting brace, and that bolt and washer were installed at St. Louis - no paint.

The R.H. exhaust manifold shouldn't have a hole in the top - that was only used on carbureted cars; the casting used on the R.H. side on an F.I. car had the boss in the casting, but the hole wasn't drilled.

The long studs on the R.H. exhaust manifold outlet are correct; they accommodate the spacer thickness (same as the heat riser valve used on carbureted cars).

Ok, the clutch cross shaft stud is mounted without paint . I'll remove the washers from the water pump bolts and wipe of the paint of the one bolt and washer holding the bracket .

The hole in the exhaust manifolt I was planning to fill with a 2 component product of Bison which is first soft but it will be as hard as steel after it is settled. Before it settles I'll ensure the texture is similar as the rest of the manuifold. Last but not least spray it orange again and hope it will be undetectable. Maybe I should put a tube in it first so the filling won't be blown out after sometime...

Rob.

Rob,
" The line should be copper plated steel. Same process as the oil gauge line."
The line you got from Corvette Central, is that the long line going to Oil Pressure gauge? JD & I were talking about the thicker line to the distributor!

As for the stud finish (paint) do not know and also need to know (bet its painted).

Rob,
John DeGregory was talking about the oil line from the fitting in the back of the block going to the distributor.
It needs to be copper plated steel just like the oil pressure line going to the oil gauge.
Good luck, Bob

Re: 63 engine over spray patterns

Rob,

Your engine pics look great, I am still trying to figure out if I like those orange exhaust manifolds.

Take a look at where the #2&4 plug wires exit the V shields, they may find a straighter routing up to the spark plugs. Seems like the wires are bent and should exit the shield straight. There is probably a better depression in the block forward of where they are now..

You are missing a ignition shielding "L" bracket in the rear by #8 spark plug but you probably know this..

Re: 63 engine over spray patterns

Rob, I believe Timothy is correct aout the 2x4 spark plug wire routing. I think they actually run under the motor mount, below the top rear bolt. The 1x3 wires are the same. About the orange paint on the exhaust manifolds, most will burn off during the first couple of runs on the engine, all you will be left with is a little orange on the alternator mount portion, & trace amounts on the cooler ends of the manifolds & french locks.

That's correct - photo below shows how the front pairs of plug wires on each side are routed between the motormount and the block.

Re: 63 engine over spray patterns

Rob,

I also noticed the clocking on your alternator is not correct for 63. Rotate the rear case counterclockwise one bolt hole and I think that will do it..
Just remove the four small bolts and hold the case together and turn it one bolt hole and install the bolts. Make sure to keep the halves together when doing this or ..

Re: 63 engine over spray patterns

Thanks, I'll do that this weekend!

Great picture, that explains it clearly!!! thanks for taking the time to post it!

Re: 63 engine over spray patterns

Should the cork gaskets [under the aluminum valve covers] show some silver on the valley side?
Spring color?

I didn't see this one answered. I found the throttle return spring called on Sect. 6, Sheet C1, so it was installed at St. Louis.

Has anyone seen silver paint along the inboard side of the valve cover gaskets ?

Yes, definitely. The intake manifold gasket surface of the cyl head, much of the intake manifold, the edges of the valve cover gaskets and also at least the inboard side of the valve cover would show dull aluminum paint.

Thanks Michael. I have been trying to figure out two things which should also be applicable to my '67 L79.

Is it possible the engine was painted with the aluminum valve covers not installed, or is this a settled issue? If the aluminum valve covers were installed BEFORE engine paint, was the mask covering the intake manifold & valve covers consistent and tight enough that it would completely prevent any orange paint overspray on the front, rear and outboard sides of the aluminum valve covers?

It would seem to make more sense to put the mask over the top of the engine without the valve covers installed, paint the engine orange, then remove the mask and install the aluminum valve covers. At that point, there is still a bare surface between the inboard side of the valve cover and the intake manifold that needs to be painted dull silver, which would also explain overspray on the inboard valve cover gaskets.


Second, if the Thermostat Housing bolts are painted silver then the Thermostat Housing must have been painted after being installed on the intake manifold, but how did they get complete coverage of the Thermostat Housing without needing to then mask the front of the engine, water pump and bypass hose?

Scott,

The aluminum valve covers were definitely installed before any engine paint operations. (at least for 63-67) I still remember orange paint on the rear corners of both covers on my new 64 365 HP car. (and dull aluminum paint on the inboard side)

Another great example is the black 63 Z06 convertible that only has about 7000 miles on it. The cover/mask must not have been in place properly and there is orange paint on much of the outboard side of the valve cover. I think I have a great picture of this here, somewhere and I'll post it if/when I find it.

The entire area around the thermostat housing was coated with dull aluminum, including the housing itself. I'll see if I can find a pic of this also.

The mask that was used to cover the engine when the dull aluminum paint was applied fit loosely over the water pump bypass hose. Many/most hoses showed dull aluminum paint on the rear of the hose and part of the clamp.
