1973 Rebuild

[Matthew Abate]

Well, I screwed up. I bought a three-tube fuel rail instead of a two-tube one because I didn't stop and think about the fact that I might need to match it to the setup I am putting together.

I'm not sure if it's for a '73 or a '74. Gotta investigate.

Either way, I need to decide if I want to modify this one or buy another one with two tubes.

Bummer.

This is my rear main cap and the pieces that fell off while cleaning it up:

Cleaning all these parts up by chamfering the threaded holes on the block and head - so that torquing the parts dosen't "pull" the threads:

And some other shots of the various threaded holes (note the cleaned block):

Casting flash on the crank case will be ground away:

Tape being applied to all of the journal surfaces before any work is done:

Update on the engine:

• Finished the crankcase grinding, cleaning, and painting
• Got the front oil gallery plug out and tapped the hole
• The paint looks very nice. Sprayed the cleaned block with prep-sol to remove oil residue, blew it dry with compressed air, then did the same with 99.9% alcohol
• Gave it two very light coats and one medium coat of light-grey ceramic engine primer paint
• Waited 20 minutes and used same method with the blue. Used less than 2/3 of the can.

Are you going to coat the inside with Glyptal like some people do?

We are still researching the right direction for the interior, but have had good results with other solutions, such as Rustoleum Ceramic Enamel, which doesn't need to be baked on.

In other news... Freeze plugs:

And luscious Nissan blue paint on the block:

Progress:

We went with Rustoleum Ceramic Enamel on the interior. This did very well in a '63 'Vette, so we're confident.

Cleaned it out:






Finished with the plugs:


Painted the inside:



And took a look at the parts for the intake setup:




Not sure what to do about accidentally buying a three-tube fuel pipe / rail...

What are you doing to do with the rear main cap?

[Patcon]

FYI Glyptol's site says bake or air dry for all but their catalyzed paint...

The damaged area was ground away and the threads were chamfered. What you see below is the cap "in-work". More chamfering was accomplished and the oil seal drain area was smoothed and polished out. Nothing wrong with it because what was ground away doesn't affect the strength of the cap.

Gotta love before and after pics! 

 

I love this hobby!

Yeah I think baking would be a required step for the interior paint? Would hate for a chip of paint to clog an oil passage.

It turns out that the stains from forty years of grease and road grit on the various aluminum parts aren't coming out.




I'm looking into different solutions like oven cleaner, Never Dull, Aluma-Brite, and such, but if nothing works we are going to be forced to go with paint because I don't want to polish it.
