1956 Cadillac Sedan DeVille Resto Video 66

[@koolkev75]

This caddy is the backbone of this channel 👍👍🔥🔥🔥

[@70malcolm]

Right on👍👍

[@michaelclose7756]

FINALLY a video on the car that brought me to your channel!!

[@rickytart1028]

Good video...Thanks for sharing....Years ago I used two gaskets on my Chevrolet 350 V8 and it solved my problem..

[@williamlane9140]

I know it's a pain in the rear but, remove the manifolds and have your local machine shop resurface them. Put them back on with no gaskets.... you'll never again have this issue...good to see the old caddy

[@dark_one1337]

except his head's ain't straight/flat

[@ShainAndrews]

@@dark_one1337 I'd be inclined to believe the manifolds are warped long before I would believe the head is.

[@williamlane9140]

The exhaust surface and the intake surfaces should have been resurfaced when he had the engine rebuilt. That's pretty standard

[@michaelcook768]

I'm sorry I didn't read your comments before I added my 2 cents...but, looks like we, correctly, are in agreement.

[@nonelost1]

@@williamlane9140 Whatever the case may be re: exhaust/intake surfaces, I don't think Ben would care to deal with whomever rebuilt the engine. It was one of those "forever jobs".

[@LarryDeSilva64]

Good job. Now that Caddy sounds and drives like a Caddy should. Thanks for sharing.

[@tompalcie6284]

Run it through a couple of heat up cool down cycles. Then go back and retighten the manifold bolts. If that doesn't work it's time to flatten the mating surfaces

[@kenworcester4387]

Thank you for the video, Ben. It is good to see your old Caddy again (and that is from a Lincoln Man! :-) )

[@dimadee]

Love your Caddy Ben. Always brings a smile :-)

[@dadsvespa]

I have owned a few Caddys , a 52 sedan, a 53 convertible, a 60 coupe, a 60 Limo, a 66 limo, a 68 sedan, a 70 coupe. Same problem. Manifolds heat up, rain water splashes up, or cold weather too, so the manifolds actually warp. Some times the warping pops the bold heads off. I removed them, had my exhaust manifolds resurface. One time a machinist just pressed it down on a sanding belt table. Within a few seconds all ports were even again. New gaskets, never had the problem again. Nice job Ben ! and Nice Caddy too ! Peace.

[@vincentbelfire2873]

For me, 56 Caddy was the most beautiful caddy ever

[@pinstripingbybear.]

I was having the same problem on my 60ty caddy limo with a 390 . Every month I had to put new gaskets on it. The last time I did them I put Orange RVT on it and they are still good to this day even for the new owner

[@TheDutchTexan]

Sounds 100% better than it was for sure! Nice seeing the caddy out and about. The trans sounds good too!

[@kimkiriniki9433]

Great to see your Cadillac again..you are so fortunate to own this old car. Hard work for you, but what a treasure it is... Well done!

[@buxxbannerspov30]

I had an exhaust manifold leak on my '55 Pontiac...the bolts were SO rusted I was afraid to pull the manifolds for fear of breaking the bolts off...so...I just turned the radio up a bit....easy fix...

[@nonelost1]

Hope you don't mind having to cup your ear to hear what people are saying years from now, because you played the radio loud to cover up the exhaust manifold leak noise.

[@buxxbannerspov30]

I've been doing that for years...courtesy of my Uncle Sam and his M1A1 tanks and such...actually I recently sold the '55 to a gentelman older than me...I don't think he could hear the exhaust leak, even though I told him it was there...or he didn't care...?

[@DavidJones-hl5om]

An old mechanics trick was to take a short piece of garden hose and put to your ear then down by the exhaust and you will find the leak I am also in agreement with the guy below that you will have to Mill the manifolds flat again if it persists

[@roderickrayrutledge2740]

I love the sound of the transmission.🙏♥️. My dad's '50 Oldsmobile had the 2 speed powerglide. I'll never forget the sound of that thing shifting going up a muddy hill.

[@siemenstraffic]

A-tisket a-tasket A Cadillac broke an exhaust gasket!

[@Freedomquest08]

If they blow out again, keep in mind that it doesn't cost that much to have a machine shop plane the manifolds so you have a flat sealing surface. Cast iron doesn't warp like header flanges often do, but it does happen. You can even check them somewhat with a straight edge.

[@michaelcook768]

A gasket would solve any deflection in the head, with a straight manifold. A header gasket, while being thicker, works well too.

[@thatcadillacguy1961]

Love the 56! Thx so much for more Caddy content.

[@lexpoppens8223]

Wow, the sound difference with the gaskets is great!

[@Nova.1971]

Great Job on the Caddy...have enjoyed the whole series. I have also enjoyed all your other projects so far, keep up the great work!!!!

As a new viewer subscriber here I am most impressed to see this Cadillac progress from rotting in someone's back yard to making it run and road worthy.

My ex graduated from Van Alstyne. I really enjoy your test drives, brings back a lot of memories visiting her grand parents up there. Love the old Caddy. Lol, Im one of those that has seen the 60 odd videos from the first run lol. Good job Ben. Thanks.

[@Spanky_Lugnutz]

Hey Ben ran into problems with my header gaskets always blowing out so had a buddy make the gaskets out of copper and used Permatex Ultra Copper on them never had an issue again hope this helps

[@dcallan812]

It's looking and sounding great you should be proud of your work. 👍

[@gs3504]

Resurfacing the manifolds to get them flat is a good idea, especially after an exhaust leak. Sometimes not only the gasket deteriorates.

[@iamrichrocker]

Ben..great to see much deserved growth of your channel..after the new folks peruse the back log of videos you have i think you will grow even more..

Wonderful old caddy. Great job on the exhaust manifold repair Ben!

[@xeroinfinity]

nice 56' Caddy ! some high temp thread locker should keep the bolts from loosing up over time. and properly torquing the bolts helps a lot too.

[@michaelcook768]

Ben, you may need to have the manifolds planed at a machine shop. I will say there is a good chance the manifolds are slightly warped...causing the gaskets to burn out. Great video...even better car! Hope the little one is doing well.

[@trashman1979]

So good to see the Cadillac again.

[@eaglefit8239]

Great Improvement!

[@sallyussher7667]

Spring washers are almost never fitted to exhaust manifolds because the heat will ruin the temper in the spring.

Really nice car. And a real name instead of 3 letters that stand for god only knows what. Pre-'58's were nice because the chrome was, relatively speaking, more restrained.

[@lblittle1207]

You can use trans fluid through carb and the smoke will reveal where the leaks are. Also can wrap manifold bolts with teflon tape to help insulate with harmonic vibrations which can cause bolts to back out.

[@maxc1084]

There is a lock washer that is used under the head of socket head capscrews. It is small in diameter and should not show from under the bolt head keeping your stock look. Castiron manifolds are famous for twisting and warping, So give them a good look over with a straight edge.

[@neooneZ1]

[@steves4639]

my '58 Fleetwood had gasket leaks too, esp at the #1 cylinder...sounded like a bad rocker arm on the freeway. debated whether to use gaskets again, but since I didn't want to pull the manifolds this time around to get them planed, I went with the gaskets. the '58 does not have quite the same amount of stuff on the drivers side as your '56, but still hard to get at the bolts...they sure angle towards the ground, and the crossmember blocks access from below. the car does not have the resonators on it now...I love the rumble, but it kinda makes it sound like a not-Cadillac. Yours is pretty quiet and dignified!

[@francispotter5300]

What a beautiful car one of my favorite thanks for sharing it

[@TBullCajunbreadmaker]

I hope that you re-torque them after they were hot. If you re-torque them when the surfaces get up to temperature the gaskets will conform to the inconsistencies in the surfaces and they will never leak again.

[@MrZdvy]

I had warped exhaust manifolds on an engine once, I just placed two gasket together, never leaked again.

[@carguy7536]

I saw a 'FORD' in TheCorvetteBen's driveway @ 10:12 Ben! I am so shocked!

I would recommend removing the manifolds and have them surfaced flat. Exhaust gaskets are asking for trouble.

I checked and didn't see one. Maybe the bolt that holds the valve cover on reflected light?

[@rikb6930]

Yay! A caddy video :) To find exhaust leaks and other noises, have you tried the putting a piece of tube in your ear, like a mono stethoscope?

I watched David F do that on an old episode of Roadkill Garage yesterday. #29 I think. Good tip...better than burning your fingers trying to feel for it.

pull manifolds run a belt sander on them check with straight edge and light.or feeler gauge.

[@txnetcop]

The exhaust manifolds on the old Caddy's have a tendency to warp...a good machine shop can fix that problem. That's is one awesome old Caddy!

[@DaveGringo]

Trick to keep nuts or bolts tight. I guess it's like using lock-tight, maybe better? I owned a '79 Caddy 425ci, one day luckily close to home I got a loud clanking noise from the engine and went way down in power like I lost half the motor. I nursed it home slowly. Sounded horrible like it threw a rod! Realized the noise was under the valve cover. Pulled the cover off to see two rocker arms laying sideways and the push rods were banging against the inside top of the valve cover by the marks left on the inside of the cover (that was the horrible noise). Put the one nut that held the pair down back in place (no lock washers on any of them). Tightened it up a lot, took it for a drive, in a mile or two same thing happened. Pulled it apart again added a lock washer to the one, made it extra tight. Took it for a drive, same thing happened again! I did notice there was gooey stuff on the threads of the stud. But I assumed it was just dried oil sludge (as there was some sludge everywhere else on the head). Luckily was able to speak to a Caddy tech on the phone at the dealer. He told me from the factory they coat those studs with brown type form-a-gasket so they won't losen up! Told me to do that and give it 12 hours to dry before starting the engine. He was right! It never came lose again, no lock washers! Might want to give that a try in the future, coat the threads and stick it in. I also noticed it stops the threads from rusting up and seazing, on other things I have since used it on!!!

[@rjh7070]

New to the channel.... Nice Cadilliac ! Keep up the good work..

[@charlesedwards471]

Hey Ben, you are a young man and I know that you are able to get up under your project cars to make repairs. However, there is a day coming that you won’t be able to do so. You need a lift, and you deserve one. Really enjoy your videos, so take care of your back my friend.

[@stevehill4615]

dunno if this would help but if the manifold bolts keep loosening it maybe as a first option wise to change the bolts as they may have gone "soft"with age and thermal cycles and also the threads may be worn, if you do decide to replace the bolts if possible try to get some serrated flange locking bolts (in the engine plant where i worked they went by the trade name of Durlok, definitely metric sizes available but not sure on other thread forms) which will lock in place but still allow you to use some anti seizing compound on the threads (we used Fuchs PBC (polybutylcuprisol) but i'm sure others work).

[@falcal762]

A quick fix..... use high temp rtv..... I got tired of replacing the gaskets on my headers and a old racer taught me that trick.... I’ve never had a problem since then with leaky headers.... just throwing my two cents in.... take it or leave it..... I like your vids!!....

[@saranpaafamily]

Remove manifolds and have them surfaced at a machine shop. Then when you go to install them, apply a thin smear of high temperature RTV red silicone. For headers, use only copper gaskets with a thin smear of high temperature RTV red silicone. On cast manifolds the bolts don’t require lock washers if they are used. Lock tab washers underneath the head of the bolts can be obtained for new bolts.

[@drew892db]

Glad to see the caddy back love this car now just throw some magna flow mufflers on it and she will be sounding real good

[@crankysports]

I have found that Exhaust manifold bolts tend to stretch, I never reuse them anymore. Put new bolts in unless it's 100% original show car, and you will have fewer leaks in the future. Thats just me though. sounds much better after the gaskets though.

[@robpustolka5368]

Love that caddy!

[@wackowacko8931]

If you want to run without gaskets, you have to have both the head exhaust flange and the exhaust manifold resurfaced so they are both flat. This is the reason that they were able to run without gaskets from the factory, because both surfaces were flat enough to not need gaskets. Over time (and especially if there are gasket leaks - gasket leaks corrode the surfaces) the surfaces degrade so that they don't allow a perfect seal when bolted together without gaskets.

[@andrewkiwi1]

You will probably find that the manifold is worn or warped which means you have to take it off and get it planed. Give them a couple of weeks and recheck them. Nice old caddy.

[@postalgreetingcards]

Much better, quiet driving '56

[@ustinman8446]

Nice job! Put that air cleaner back on And you're good to go. Dash Looks great I'd really like to see You do a rattle can paint job on the body!

[@GWMRed]

Exhaust leaks in both my folks' 1955 and 1956 Coupes de Ville were usually due to rusted pipes. I can't recall the large number of metal frozen juice cans and feet of copper wire my Dad used on those repairs...can't do that today: no metal juice cans, but maybe a dog food can wouldsubstitute

Great to see the old girl again, and also chopstick... What did you ever do about the backseat? So another KZbinr apply varnish so his car preserving the patina until he could afford to paint his car. Thanks again for the update on the old girl!

[@vettekid3326]

With exhaust gaskets all your trying to do is compensate for an out of flat fit between the manifolds and the heads that's why when taking loose exhaust manifolds they have a tendency to warp from the accumulated hot / cold cycles and should be resurfaced to true them up before re-installing.

[@goneshootin61]

You should re torque the bolts after the engine has cooled down that should help from backing out .

[@farmerbob139]

I think that's called a shouldered bolt. murphy's law, fix the loud exhaust and the noisy transmission sticks out like a sore thumb. :) that being said I don't think you have wasted your time pouring the love into that old caddy. :thumbsup:
