Hunting Down Vacuum Leaks On A Carbureted Oldsmobile

@@kramnull8962 In my defense as a young guy who went through auto mechanic training 10 years ago none of our instructors even taught us how to work on older stuff like carburetors or even how they work. They just taught us how to work on modern cars because when you go out into the world looking for employment as a mechanic that is usually what you will be working on. Can't really expect us to know how to fix or work on stuff that we have never been taught to fix and have never had the opportunity to even work on.

Vacuum stuff is neat though because it is analog and 99% of the time can be repaired with out replacing any parts with the exception of vacuum hose. The old vacuum ac controls were easy to diagnose and fix but the modern electronic ac blender controls and actuators usually fail without warning and generally have to be thrown away and replaced. They both have their issues but the vacuum stuff seems to have stood up to the test of time better.

[@somedudeRyan]

[@blair79bear38]

Not this mutt. lol I can do my own stuff. Quadrajets are my thing. I'd have pulled that carb off the engine real early. much easier to deal with the vac leks around the carb. verify its got the right gasket. examine the throttle plate to make sure its not damaged. Jiggling the accel pump is an easy way to see if its still lean and that engine was dramatically lean. but Tony didn't waste much time getting it a lot better than it was. incidentally that is a '74 or earlier carb . the '75 and later has different look at the front. I like to pick electric choke carbs as they are much easier to get the choke ligned up properly for a tap the pedal once and crank. The choke pulloff solenoid seems to be missing. the choke would hold the plates solidly closed . the extra rich would suck fuel into the engine rel quick and the pulloff as soon as there is vacuum would pull the choke open to a proper setting. allowing the engine to run without flooding. the heat riser and various other choke systems are far more finicky. One more thing, without the choke being held open the linkages will prevent the secondaries from opening. Not surprised by the customers report of the first attempt of having a bad float. current remans are of horrible quality.

@@blair79bear38 I agree with you. Quadrajets are the easiest carbs to get functioning correctly, consistently and smoothly. I just recently found out from online forums and stuff that the have a bad reputation, which blows my mind. It's so much easier to get a good running chevy with a Quadrajet than a Holley or eldebrock etc. I'd say it takes very little intelligence or mechanical aptitude to work on anything automobile related but I've been blown away with all the ridiculous comments about such an old and simple device as quadrajet carbs. People really over think Automotive mechanics. It's technology that is well over 120 years old, vast amounts of information available for free but folks just make it seem so difficult. Anyone with an IQ at the bottom level of average can learn all aspects of this technology within a year or two if they would just look at it, for what it is.. it's simple well over a century old technology that a monkey can do

[@bannockchief]

Old-school mechanic here. First, that's a Chevy Q-Jet and not a BOP "electronic Q-Jet" as it came from the factory, which is why the rear vacuum port didn't fit. But a pre-1981 BOP (Buick Olds Pontiac ) Q-Jet would have worked perfectly. All vacuum ports would have matched and not had the issues this one had. Tony worked it the way it should have been with what he had. This is a great venue to show the young'uns how it's done.

I could see that that carb didnt look right the fuel filter inlet was side ways . If that engine was a 350 it must have been an older chevy 350 or possibly an older olds 350. It looked like there was an inline fuel filter also it wouldnt come equipped that way from the factory, you could add one I guess if you wished or maybe the original car filter fitting was stripped out?

Great idea for a video series, should be very helpful for beginners learning how to diagnose issues. I think you should try to explain things back a bit more in the next one. I realize video length is a concern, but you gotta remember that most folks don't have that ingrained understanding of how engines run that an experienced mechanic does. You're doing a good job of showing what to do, but it's the whats along with the whys and hows that allow people to build their understanding and start to connect the dots on their own. You got a car in that doesn't idle right and runs rough, so you suspect vacuum leak. What's a vacuum leak? Why do you suspect it, and why does it cause the engine to run bad? How do you fix it? What does covering the choke do? Why does squirting gas at a leak cause it to smooth out? To people like us, it's almost as natural as breathing. To the average joe, it's witchcraft.

Great video! This is the stuff I like to see. Real time troubleshooting and the narrowing down of all the iissues to get to a solution! good Job Tony!

This video was excellent!!! I’ve watched most of UTG’s videos and many other videos on various auto mechanic channels, but this video is exactly what I was looking for. It’s especially helpful to see your thought process, in this case, eliminating potential sources of the vacuum leak, until you found the ultimate cause of the rough idle. I recently bought a 66’ Lemans with a 400, and I’m battling my own rough idle. I was curious, could a vacuum leak also cause an off-idle stumble? Once again, excellent video, please create more! All the best, Adam (Queens, NY)

Yes, Sir! Always use a good refresher course UT!!! Nice, Cutlass! THNX!

Couldn't have picked a better example to chase vacuum leaks on. Those mid 80s carbureted cars had miles of vacuum lines on them. One thing I kept looking at, was the EGR valve beside the carb. Those are known to stick in the open position a lot. The carb base plate is definitely leaking big time though.

[@markchwala]

Sometimes the egr valves have a leak in the diaphram and will cause rough idle, hesitation or stalling . I plugged mine off and the car ran better!

I love this channel and the straightforward, no-nonsense approach, as it has helped me wrap me head around some 4-barrel carb stuff, which is outside my norm as a Porsche/BMW mechanic.. However, some sort of smoke testing tool would have significantly cut diagnosis time! I have professional tools at my shop, but I have also seen KZbin videos using party smoke machines and the like. That particular car seemed like a nightmare in terms of potential vacuum leaks, but instead of gasoline, carb cleaner or brake cleaner can do the same job in a pinch, while being somewhat safer. But, you are still around after 40+ years of doing this, so I won't yell too loudly :)

Q-tips that may help out next time. Never put more then 12 ft. lbs of torque on the mounting nuts/bolts. At minimum you want to turn out the idle screws 4 turns. Use screwdriver down air horn vent tube to be sure power piston is is moving up and down. Can visually checked with engine idling as well. Make sure there is a fuel filter. If no filter is present.. Or just because. Do a quick trash/debris removal. Rev engine up to 3,000+ rpm. Slam the choke plates closed and go to WOT. Right before engine dies. Let off and feather throttle open and closed until it comes back to life. Repeat as necessary and most likely will benefit from doing this 2-3 times.

Great video….. I was helping my son take out the engine in his car…. Being in a house of 3 women, we used a new tampon guys, not used, to plug heater hoses, they did work good, lol….. Should have had a warning about spraying gas under the hood….. warning would be Do not spray gas on extremely hot exhaust manifolds and warning make sure your spark plug wires are in excellent shape or spark can cause fire hazard, lol… I like how you can see in the video the repurposed spark plug in the end of the vacuum hose. I like to see you using your hand and ears to keep the fuel balance correctly as the engine smooths out…. You have to listen to what she is saying!!!!……. Keep up the good work guys I like how you asked him if f he screwed around with theses screws, lol

[@jasont.1530]

That was educational for me to watch!! Thanks Uncle Tony!!! This hands on video is invaluable!

[@timclough8402]

Great concept! Endless possibilities to fix all of the issues on different vehicles! Looking forward to more of these videos! Thanks Uncle Tony!

Great video shop class all over again. Loved it.

Answering the question: Yes, I got something out of this. I really thought this was going to be a case of the EGR Valve being stuck open. I never expected multiple vacuum leaks at the carb. Good work UT. I enjoyed the entire procedure. I'd like it if James came back with a report after fixing it. That's real nice looking Oldsmobile. I've always liked Olds mid-80's styling, and James seems to be a great body man. I'd have liked a pan of the car. This is unrelated and I've never done this before, but some may find interest here. We're living in a distrustful time. I want to offer observations that point toward a stranger being a good person. James is a nice guy. His overall demeanor is good and he's polite. He's honest. Unasked he became engaged in making the effort to help, first by holding-open the choke plate while UT fastened it. Then he offered his own trim screws. Then he offered his own long screw driver. He assisted in a genuine way without complaint, and made himself ready to help UT. And he was a gentleman from start to finish. These things say a lot about the goodness of a man.

I know this isnt a CCC car, but on the mid 80s gms with the CCC feedback setup, if the temp sensor on the intake goes bad, they'll do the same thing and refuse to idle. Case in point, my 84 delta 88. Those 90* fittings on the brake booster line loves to crack too. This was fun. Showing that the basic troubleshooting skills can apply across all makes.

[@thisisyourcaptainspeaking2259]

It was originally a ccc car but not anymore since it's got the wrong carburetor. Who knows what else is missing.

[@markchwala]

@@thisisyourcaptainspeaking2259 The original motor was pulled out I suspect which was a 307..I have seen the young guys wanting more power so they find that they can swap in a chevy 350.Many times they disconnect the computer system and remove the catalytic convertor and change the distributer.Henseforth it is a cobbled mess many times.The carb in that video looked different and the mixture screws were adjustable.They are usually sealed at the factory and have to be drilled out or tapped out to allow for adjusting.It looked like he had two breather caps instead of one and one pcv valve that was missing.

[@thisisyourcaptainspeaking2259]

@@markchwala Maybe you're thinking of the ccc 305, I don't recall ever seeing the 307 with feedback carburetion. Anyway, if ccc is disabled then the electronic advance distributor will need to be addtessed. A 350 should run fine on ccc, and you get the benefit of locking the torque converter if the th350C is still there. I'm still running the original th250C in mine (231V6) it won't die!

[@markchwala]

@@thisisyourcaptainspeaking2259 I have a 1985 cutlass supreme with a 231 v6 it has a lockup torque convertor .Both trans and engine have been very reliable.Only things that go wrong is the rear main seals leak I understand it is a split seal. Also the intake gaskets leak because the engine has an aluminum intake and the intakes sometime warp. I have a 1986 cutlass with the olds 307 v8 and it also has an aluminum intake and the former owner had the intake milled and a new intake gasket installed at dealer and I had to have said intake gasket replaced a second time! The 86 olds cutlass has a 200r4 trans with overdrive.

[@thisisyourcaptainspeaking2259]

@@markchwala I have the aluminum 4bbl intake from the larger 4.1 Buick V6, it runs like a scalded dog. I'd forgotten the olds 307 was still in production in '86. Those BOP and uni transmission bell housings have become progressively difficult to come by, they're worth more and more as time passes.
