BUILD THREAD Sweet Johnny & Gina: A Love "Two Large" To Fail

Here's a picture of that fuel pump after it was installed and the sun was shining again.

I changed the oil and discovered that the previous owner had been using Napa Gold filters, which jived with every other aspect concerning the care and/or condition of this vehicle.The oil looked great for being as old as it was, and the drain plug came out clean as a whistle.

I next went about fixing a few vacuum leaks at the intake manifold. In the following picture you'll see one of the leaks fixed by simply sliding a short piece of vacuum hose over both ends of a tube that had separated at a joint. You'll also see the other tube that had separated from the plate on the intake. There was no tube protruding from this port so a piece of hose wasn't going to be the solution. I used a bronze bristle brush and brake cleaner to clean the area prior to taking this picture.

I proceeded to mix up a small amount of JB Weld Kwik Weld and applied it in doughnut fashion around the tube prior to reinstalling it on the engine.I slid the tube into place, pulled it up slightly, and slowly pushed it all the way back into its home. I don't have a picture of the aftermath but I assure you it's beautiful, and only because I couldn't reach it to mess with it. The doughnut bit sagged a little as it dried, but since I chose the Kwik Weld it didn't run.

Tell us more, Tell us more,Tell us more, Tell us more!

Ah hah, ah hah, ah hah, and an hah!

Out of curiosity just checked Wichita, no G Body parts cars there at present.

Did find nice S10 current bid is $25.

Found a 77 in Phoenix, not assigned yet.

Found a few other GBody elsewhere, not assigned yet. Found nice 79 Monte, but mainly Cutlasses. Nothing assigned yet.

I bought an Olds, from seventy-eight.
I fell in love, and things are just great.
Her small block is a Chevrolet.
And we went for a drive tonight!

Like In the other movie: "I will look forward to your explosions!"

 

[Sweet_Johnny]

I'm kind of hoping for a lack them to be honest.

Well I was thinking more of tire smoke, the fun stuff. Not thinking of breakage. Breakage is bad.

Thank you for decoding that for me/us, the only thing that doesn't line up here would be the interior: it's all blue, all of it. If someone swapped it out they were quite thorough. I really like having this type of information since it helps complete the backstory of a car that's 45 years old.

Unfortunately, as of June 1, 1977 print date, Olds did NOT offer a blue interior in a black 78 Cutlass...only black, white, red, or tan. I suspect some fading of your black stuff here. Unless someone redyed it. Looks as if the faded black theory is correct. When you remove something like the center dash woodgrain vent plate, look at the color of the dash vinyl behind it. (VERY CAREFULLY. Those clips can be a **** and if you hook the top vinyl layer with those hooks, yanking the piece out could either break the vent, or rip the vinyl right off the dash piece. Or both.

You didn't just JBWeld that tube back in place did you? AAAAAAAAAAGH! NO. The rubber hose connector to the other piece is ok, but it appears to me this is the heat tube arrangement for the hot air choke.

That tube is MEANT to be a slip fit. Have fun getting it out once you welded it in place. Not that it will be the end of the world, but now it's ONE piece. Maybe it may break loose.

Here's kinda how it should look in the pic below. The EGR is removed here. Filtered air comes in the top of the rear of the carb by the secondaries (in that void area next to the top plate screw), and travels down into the heat stove tubes in the manifold where it picks up heat and then sucked through the tube to the choke housing (you can see the heat stove U-tube peeking out of the crossover in the intake picture below). A tiny port in the choke housing area is directed through the front choke housing mounting post on the carb (can't see it here in this pic) and travels through the porting in the carb body to the bottom of the throttle plate. Vacuum source is by the engine vacuum. That tiny port in the choke housing where it meets the carb body has a plastic orifice inserted there that acts like a little gasket where the two meet as well.

This is a DESIGNED VACUUM LEAK. It doesn't care where the air comes from, the engine is set up to have the air get sucked through that tiny little hole in the choke. But to get the choke to work, you need to have the tubes intact enough to get hot air into the choke housing.

See this video to get the idea. YOU DON'T WANT JB Weld in the tubing system. But you also need to watch out for broken/corroded heat stove U-tube. Like in the video. Watch the whole thing.
