[@scrappy7571]

I bought a '56 Cad with a smoking engine. Replaced valve seals, and still smoked like crazy. Pretty sure the engine was worn out, but was poking around and found oil in a vacuum hose that went into the oil pan. Thats when I discovered the hidden vacuum pump. Ended up plugging the hose and using only manifold vacuum for the wiper motor. NO more smoke!

[@OpenRoader]

At 15 years old I bought my first car. I had it for about an hour. The year was 1983 and I had a whopping $500 to spend. An old man up the street from my house had a 1956 Cadillac Fleetwood Limousine Series 75 for sale. It had been sitting on the street with a for sale sign in it for ages. It was dark green with long rust stripes from end to end. Without my parents’ permission, I knocked on the door of the seller and in my most grown up posture and voice I inquired on his automobile. He asked me if I had a driver’s license to which I replied "YES" (lie) and I quickly asked if his wonderful machine ran, to which he relied "Of course it does my boy" and handed me the keys! He was probably in his late 70's early 80's. The two of us walked out to the curb and I opened the creaking driver’s door. The interior was deteriorating and covered in cobwebs, but I saw beyond all that. I placed the key in the ignition, he instructed me to give the gas pedal two stomps and to "Light it up". To my amazement it fired up after two revolutions and went straight to an idle. He proceeded to tell me that it had a 365ci engine and that it had power windows and power seats and that they all worked. To my surprise, even the clock was ticking! Without hesitation, I laid my money down! He quickly produced a pink slip and allowed a 15-year-old to roll away from the curb with an 8,000lbs car! I must have looked like a baby in a high chair behind the wheel. I couldn't see to the end of the hood. I made the 500-yard stroll at idle speed from the front of his house, to the end of the block, right on to my street, a full U-turn and parked the great green mastodon in front of my parents’ house. When my parents returned from shopping, I was out front with a bucket and garden hose giving my new love a good wash. I still remember the look of shock and bewilderment on my mother and fathers face when they asked "What the F*** is that?" I stated with great pride "Its my new car!" to which my mother yelled back "The F*** it is!". My mother demanded to know where I got it, but my father already knew. He recognized it from around the corner. I did my best to plead my case. To which my mother proclaimed, "You’re not parking that giant watermelon here, it takes up all of our parking space!". She did have a point there. Before I could even turn off the hose, my dad yanked me by the arm, shoved me into the passenger seat, fire up my rolling road block and drove it back to the seller’s house. The feeling of deflation still stings. Without argument, the old man returned my money to my utter disappointment, but he still gave me a thumbs up and a smile for tryin'. The Cadillac sat there for another year before the city towed it off. The old man is long gone now. Passed into history. I'm hoping the old Series 75 somehow survived the crusher.

I have never had so many 'paper 'cuts on my hands as when putting rings in an engine. End of the day wash your hands and Man do you feel it. They will cut you so many ways and not always draw blood. As a kid, with my Dad, lapping valves and setting rings were my two biggest responsibilities and watching you put in and take out, file, fit, place on the pistons (I didn't have a spreader) brought back memories (maybe not so fond).😕

[@hydroy1]

Davin , This is why I watch these assembly's to see if I can pick up any CHEAP tips I don't already incorporate in my builds! I like the idea of placing the rings after file fit to number them on the WOOD ! work bench ( I like it ) . For decades all I did was mark the individual ring and put top ring & 2ed ring in a baggie and mark the bag with a felt pen or a slip of paper for each cylinder, but when you do it that way the rings stand a chance of hitting each other in the bag before assembly so I will use your way from here on. Now let me add a few zero cost tricks I use. Instead of spending cash on a ring grinder, I just use a brand new double cut Nicholson flat file locked into the vice and just stroke each ring on the file a few licks at a time to open up the end gap clearance. True it's not as square that way, but I never heard a complaint out of any motors I built from the rings as long as the end gap is correct. Also you don't need a special tool to square the ring in the bore to check end gaps. Just install 1 old ring ( off the old pistons )in the second groove of 1 of the old pistons ( that you clean up on a wire wheel & brake clean ) Then use the old piston & ring to push down the new ring in the bore to square it for checking end gap. My dad showed me that one over 50 years ago and that's the way I build all my motors for decades. We was poor folks and we had to use any spare money we had for food, not custom toys that just lay in the tool box that you really don't need, but you get almost the same results. Building stock motors is all about saving money on a motor that runs well for many years.

[@DanielDiPaula]

Davin, watching you work in such pristine conditions provokes my envy!

[@GenderSkins]

A trick I learned from an old Army mechanic, for fixing vacuum driven windshield wipers was when the vacuum pump went out was to just move it up to the intake manifold. We had the same issue with our 1940 something Willies Jeep, as it had vacuum driven windshield wipers and they was always acting up. And my dad being that old Army Mechanic that taught me how to work on car's, and the one that taught me how to fix the vacuum driven windshield wipers. He was also the one to install a fuse box into that Willies jeep to get it back running.

[@chefdan87]

Never heard of the vacuum pump for the windshield wipers in the oil pump either. You learn something new everyday. My friends father was rebuilding a 55 Cadillac coupe deville and under the hood was a box about the size of a toaster that i didn't know what was or what it did. I asked about it and he told me it was for the auto dimming headlights. i didnt know they had such a thing in the 50s. Thought it was comical how large it was for the simple job it had to do. But technology back then wasn't near what it was today. Auto-tronic eye.

[@CrazyPetez]

My dad had a 1960 Mercury that had vacuum windshield wipers. Manifold vacuum disappeared when driving uphill, especially steep San Francisco hills. The solution on the Mercury was a dual diaphragm fuel pump. One side diaphragm pumped the fuel, the other diaphragm pulled vacuum to enable the wipers to work uphill and down.

[@MaShcode]

Ah, so thanks Davin for clearing that one up. Been rattling around my subconscious memory since youth. Before modern intermittent servo driven wipers (when they literally sucked), my mom would always have to pull off the highway during heavy microbursts because the wipers couldn’t keep up. Once she slowed down the wiper speed would change dramatically. 👍🏻

[@mrnicktoyou]

If this was my engine being built by this person I would treasure it forever.

[@stevemiller6766]

I think the reason for the vacuum pump on the oil pump drive is that it would produce a steady high CFM of vacuum so the wiper speed would not change with throttle position. Going up a hill in an old 53 chev pickup the wipers would slow to a crawl since the manifold vacuum would fall to nearly nothing. Then on the downhill side they would go so fast they could fly off since the throttle was closed causing high manifold vacuum. Love the shop you get to work in Dave, it would be a dream to have that to work in.

[@get2dachoppa249]

As an aircraft mechanic, I immediately recognized the vacuum pump for what it was. Sliding vane vacuum pumps have long been used throughout general aviation to power air-driven gyroscopic instruments such as the artificial horizon and heading gyro.

[@pauldeutsch2044]

This is the most meticulous job of engine building I've even seen here on KZbin. Kudos to you. I have one criticism and that is your torque wrench technique. I was taught in the Air Force that to get the most accurate torquing the wrench must be pulled towards your body, not away from it. And it must be done slowly so that when the dialed torque is reached it will come as a surprise. Kind of like pulling the trigger on a gun.

[@oh8wingman]

The reason for the vacuum pump on the oil pump is fairly simple. In the days of vacuum wiper systems, manifold wipers had a real problem with varying engine acceleration and deceleration. When you punched the throttle the wipers could and did actually stop on some vehicles since your manifold vacuum was down around zero. When you let off the throttle and coasted the wipers would speed up like crazy due to the higher vacuum. This equated to a lot of fun when trying to pass someone or going up a hill on a two lane highway in the rain. You punch it and start to go around them with no visibility because your wipers have slowed or stopped and were no longer effective. This system employing a rotary vacuum pump was only used on higher end vehicles and what it did was give you a positive vacuum regardless of throttle position. They were designed so that they produced enough vacuum to run the wipers at an idle and only got better from then on as the engine sped up. My Father had two cars in the late 50's. One was a 1953 Cadillac and the other was a 1950 Mercury with a flathead V8. The Cadi was his "only on Sunday car" unless it was raining. I asked him why he drove it in the rain since it was special and he told me that the wipers always worked as where the Mercury's didn't. Since he was commuting about 30 miles to work on a two lane no shoulder highway it made sense to use the safer vehicle since there were a lot of farmers wandering down the road at 20 to 40 MPH instead of the legal 55 MPH. If you had to follow them for any length of time you were late for work.

[@wymple09]

My late 50's Oldsmobiles made vacuum for the wipers at the head of the fuel pump.

[@torentmonkey]

Best hack in case you don't have a ring compressor. Get a huge a2s hose clamp that would fit the ring/piston, and compress the rings, one by one. Takes a lot but saves the day.

OK so when the wipers used manifold vac. - you hit the gas hard and the wipers all but stopped - you took your foot of the gas the wipers went to warp speed - the use of a vac. pump was the deluxe system - why caddy put it in the oil pan ? well that's just Cadillac for you !

[@dannywilsher4165]

What I was wondering was where the exhaust went from the vacuum pump... Would it create blow by in the crankcase?

[@n4zou]

The school bus I rode in elementary school had vacuum wipers. They also had manual lever's. When it rained hard the driver would let one of us kids stand beside him and manually operate the wipers when going uphill.

[@dannywilsher4165]

@@n4zou Cool story!!!

[@dougmaclean9752]

the engines of that era had crankcase breathers ( a cap on the front of the engine with a horse hair type of filter ) that let fresh air into the crankcase . and they had a road draft tube that went down the back of the engine to exit in the air stream below the car which caused a slight vacuum as long as the car was moving . My guess is that a slight amount of air induced into the crankcase would not cause a problem .

[@dannywilsher4165]

@@dougmaclean9752 Yes sir, I totally agree with your comment. But inquiring minds asking questions helps jog comments from people like you to maybe explain things and help others learn. I owned a wrecking yard and had thousands of old engines with this breathing type of ventilation that you explain in your comment. I also owned an automotive machine shop and built numerous engines with this type ventilation. Worked in it's day I suppose but what we have now is so much more better!!!

[@skylinefever]

2:04 In addition, some pre gapped rings have a gap that is too wide. It can even be caused by someone putting the wrong type of ring in the package. 19:30 As for the vacuum pump, it exists because there is very little manifold vacuum at full throttle. In order to keep the wipers going at full throttle, there has to be another vacuum source. You get really used to vacuum pumps if you work on cars with diesels, since a diesel doesn't produce manifold vacuum, and therefore vacuum devices require a pump.

[@blakethompson8022]

Reminds me of a hurricane 6 in a willy's. They had a dual action pumps. One side for fuel, other side for vacuum...for the wipers. Take a hill, and they'd slow way down...down the other side, they'd be better than new lol.

[@bryanh1944FBH]

I believe it made sense (in the day anyway) to put a vacuum pump on the oil pump. It's a rotary vane type vacuum pump. It needs a thin film of oil for the actual seal, as well as component lubrication. I didn't see it in the video, but I suspect there was some way the vacuum pump got its oil from the oil pump. Then, the excess oil and air simply went back into the crankcase. I also believe the windshield wiper motor used filtered air from the air cleaner housing.

I can't remember but it was Hastings or Perfect Circle that recommends using WD40 to lubricate your new rings . They say that it gives just enough friction to seat the rings . I have been doing this for years now , works really well .

[@steves4639]

owner of a '58 Cadillac here. As anyone driving a car with wipers run off manifold vacuum can testify, the wiper speed is inconsistent at best. vacuum off the oil pump is always available...at least while the car is running. and vacuum wipers are nearly silent, which was an important feature to Cadillac...

[@lbh002]

The vacuum pump is an awesome idea, even if it is put in a rather odd place. Using manifold vacuum to run your wipers has issues. Your wipers would run fastest when you were stopped and at idle. You need them the least at this time. When driving up a hill and you have to floor the accelerator, as I did on my old Comet with a 170 straight six and a two speed auto, to go up a hill you would lose almost all of your vacuum and your wipers would almost stop at highway speed when you needed them most.

9:30 I was taught to always put the compression ring gaps 90° apart. You mentioned that about the oil ring supports but not the compression rings.

[@santerresongarage7486]

The idea about indexing rings is good, but at the end of the day it doesn't matter if they are 90*, 120* ,180*. With the cross arch patern in the cylinders, rings rotate at a few rpm, and not necessarily at the same speed of eachother.

[@syncrosimon]

[@AndrewWallacelive]

Packard used a similar oil/vacuum pump design (probably the same AC pump design, in fact) on their V8’s and having air and oil next to each other has proven to be a problem as those engines have aged. Foamy oil doesn’t lubricate very well, so a lot of the guys have changed those cars to electric wipers and used a modified pump setup to eliminate the vacuum section. Worth considering...

[@vettekid3326]

Actually putting the vacuum pump on the bottom of the oil pump makes sense over the other practice of adding it to the fuel pump that would fail and have to be replaced and if you ever bought one even back in the day they were a lot more expensive than the ones without the vacuum pump. Also I first ran into the problem of people not knowing orientation from a clock back in the early 1990s when I was instructing some people in CNC programming because we would use that for direction orientation in making XY moves and some of the younger ones were totally lost.

@Davin!! I realize I'm chiming in on an old video...but i have a question about the build process. Around 6:25 mark where you're talking about having completed the process of file fitting the rings to the bores - so at that point you labeled them on the table to keep it straight and don't mix em up. my question is this: then you go over to a box of pistons with the rods connected - ready to go into the bores - at that point could any piston still go anywhere? I'm kinda wondering if these loose pistons in the box are also - already numbered? Seems like in the previous video where you were describing assembling the big-end bearings / torquing the caps so you get the numbers off to Thirby's to cut the crank journals - at that point wouldn't the pistons have a fairly pre-ordained location? or maybe your numbers (2.238) were consistent enough across all 8 that literally any piston could go anywhere? seems unlikely tho.

On the vacuum pump, vacuum wipers had been run from manifold vacuum from the first. And it was a lousy system. The wipers would slow under acceleration and then go hell for leather when backing off the throttle. To improve this, a vacuum pump was later used, particularly on upmarket cars, so as to keep the wiper performance even. But I hadn't seen one in conjunction with the oil pump - in conjunction with the fuel pump was much more usual.

I found an old KMZ Dnepr military sidecar motorcycle in a barn where it had sat 27 year's. When I pulled the head's and cylinders off the ring gaps were all aligned where sliding the cylinders over the rings with just your thumbs to hold them down the easiest way was done. The Russians treated the Ukrainians as slave labor during the Soviet union days and so the entire bike was like that. I took the entire motorcycle apart and put it back together correctly.

I personally like that you used a sealer/paint for the lifter valley of the block and pushrod hole areas on the heads to speed up oil return to the pan.

The first engine that I know of that had the vacuum pump on the oil pump was the 55-56 Packard V8. I have 2 Packard engined cars. A 374 in a 56 Patrician that has the vac/oil pump, and a 352 in a 56 Hudson Hornet that has a dual action fuel/vac pump. (AMC used Packard V8s in their big cars in 55-56.) I have no idea why Hudson did that. It is thought the vac pump accelerated wear to the oil pump shaft, but that wouldn't have happened until many thousands of miles.
