WILL IT FIRE UP? WHY NO OIL PRESSURE? Under the bonnet at OCC HQ

- Garage time at OCC HQ, will the old Dodge fire up after fuel supply problems recently at a classic car meet? And why is there no oil pressure showing on the gauge? Regulars will know that the 1947 Dodge's engine was very reluctant to start at a car meeting recently, in this video I delve into the carburettor to see what's going and whether the problem(s) relate to that or something else. Will it start? If you've ever wondered "how does a carburettor work?" then maybe this video will answer a few questions.
(Apologies for slightly odd audio at a couple of points in the video).
While trying to start the engine I noticed no oil pressure registering on the gauge (it usually registers pretty quickly), so a separate investigation is launched into that at the same time as trying to fix this reluctant starter.
Running a classic car or truck is rarely straightforward, especially one that hasn't seen a great deal of use in recent decades, so "failures to proceed", while unfortunate, aren't entirely unexpected, although sometimes finding the cause(s) of the problem can take time and a lot of experimentation, checking parts, swapping parts for better replacements, and a lot of head-scratching usually.

Your audio level is overloading your camera's in-built microphone. Try a better quality wireless microphone with a furry cover to block wind noise.
@@stephenholland5930 Yes I use a mic similar to that on my other camera, it just had a bit of a wobble while in the cab for a moment hence the note in my pinned comment
I have to say that tinkering videos at OCC HQ are my favourites, although all your content is most enjoyable.
Thanks hmb, they don't tend to get great views but they add to the mix on here, thanks for watching
Good job, Richard - takes me back to the 1950s and 1960s when I used to work on my own cars. I like your logical approach to solving problems.
Thanks Nev!
A very educational video Mr OCC, I enjoyed that. Great to see you get the old girl fixed!👍😁🚗
Thanks 👍
Excellent war chest of bits Mr OCC!!
I simply couldn't getting anything done without boxes of junk to hand that I've hoarded over the years, springs included :)
@@oldclassiccarUK No man should be without a box of assorted springs.
Job done ! Have to add Richard my mechanical post repairs on my old cars always ended in failure .......so l stick to the bodywork and paint . Each to thier own ! Cheers !
Great piece of work, the truck sounds better/smoother running. Very nice video. All the best Bob
Thanks 👍
Excellent video😊very interesting
And a job well done
Glad it’s fixed⛽️🛞👌
Thanks😊
I do think you have fixed it. Good job and good luck
Thanks, I hope it's ok now
Great work Richard
Thanks Richard!
glad it was a minor issue, a bit tricky to find but great work. Funny about the oil pump , only a fraction in the thickness of the two gaskets. Love the tinkering videos, need more of them.
Thanks for checking it out!
Can't beat a tinkering video🤗😉
Yes always used Coloutune on my twin carb Spitfire and it worked!
Yes they can be useful on multi-carb setups in particular
A job well done cheers
I think I would drill a small hole in the float which should allow the fuel to drain out of the float. Only a tiny one. You may be able if you can pressurise a little through the known hole find the leak under some water but almost certainly around the seam Once you find the leak solder it and then solder .the small hole you just drilled. Holding the float under water should reveal any further leakage with bubbles.
Yep it should be fixable, I did have it in a bowl of water and couldn't spot a leak, it must be miniscule
Nice work Dad no doubt Harley is learning a lot from you so all is good nice work Sir.
Jobs well done.
Fingers crossed!
What a relaxing video! I admire your patient attitude to tinkering around with the carb as many people would have simply ordered a new one. I know that this is outside your normal operating radius but on the 1st of August there is the Corbridge Classic and Performance show which is held in this beautiful and historic Northumberland town situated on the River Tyne near Hexham. I'd love to see you and one of your beautiful cars there or you could make it a real family weekend out as there are a lot of hotels, pubs and b and bs for accomodation.
Thanks, always better to fix an original old part than dip a toe into the unpredictable world of modern repro parts!
A Colortune is ideal for working on older vehicles, so to check mixture and idle settings I used mine when carbs were normal fitment before fuel injection and cats came along.
Yeah, float level definitely too low. Check for air leaks between fuel pump and fuel tank (seen that one before), check fuel tank is being vented, check there are no restrictions in fuel line out of fuel tank. There is usually a 'sock' over fuel outlet in tank, have seen them blocked also. I'm guessing you have already tested fuel pump, maybe worth checking fuel line between pump and carburetor. Usually those older Carters are OK. You could maybe drill a small hole in the float and gently heat to remove fuel and then silver solder it giving the original soldering a touch up. Sure, tricky job, not for the fainthearted, but rewarding.
Yeah have been through most of that, the tank was replaced before I bought it. Thanks for watching and commenting.
@@oldclassiccarUK More "armchair" mechanics......................
Googling an exploded view of your Carter carb might show the missing spring. I'm puzzled how such a small difference in the two gasket thicknesses had such an effect on the oil pressure. Excellent video - nice to to be taken back to the good(?) old days by your under-bonnet tinkering. I wonder if Kurt watched the video?!
I've heard of similar with top plates on oil pumps like this, even distortion can affect pressure.
Hi Richard. The truck needs some good old American Texaco Gasoline in her. Andrewsnoozey commented and left some helpful ideas. Good that you got it out on the road for the test run. It was back in running order. Did your youthful assistant have a good time at his prom ?. From Carl in NZ.
It's all pretty normal stuff, I did a video about the Anglia a couple of years ago when that had float/carb problems too. No prom yet!
The Dodge probably doesn’t require a MOT was just wandering about cracked Windscreen , great video
I might get them changed one day but they've probably been like that for 50 years so I think they'll be ok for a while longer. Thanks for watching.
Looks okay to me..............
hi Rick, great video, back in the 70s i always used a gunson's colour tune for the old land rover, carbs really try your paitence at times, but well done with this, is the oil ok in the air-cleaner ?
Think so!
Good video....brought back nightmares of the carb on my 1952 Dodge pickup! Floats woth gas in them need replaced or a specialist can resolder them after draining the liquid out. Those screws holding the carb top on are filister head screws by the way. Pardon my nerdy-ness!
Ha I knew that someone would know the correct name for them :)
So pleased that you've sorted the problem on the Dodge. Do you intend to work on the A40 restoration this summer? Maybe too many car meets on the calendar?
I'd like to do some work on the A40 yes, coincidentally I'm looking around online for parts right now
I had the same truck but RHD here in OZ for 10 years. Very reliable never let me down. Mine had the Richards ute body . Engine 218ci Canadian 3 and 3/8 bore these blocks are 1" longer than the US blocks.
Tinkering at its most engaging. Fingers crossed she's fixed.
Thanks, I hope so too :)
exactly the same issues I had recently on my Rover P6 - 2 new floats, 2 new needle valves and back to normal. Of course it was easy for me to get the parts the same day just a few miles from my home, given it's a British car
It was re-jigging the linkages that made the biggest difference on mine, fortunately I was able to find a used float with a military Dodge parts supplier. The oil pressure thing was a tad alarming for a few moments until it clicked in my head why it was.
@@oldclassiccarUK still watching - haven't got to that bit about oil pressure yet 😆
@@oldclassiccarUK of yes seen it now, you wouldn't have thought the gasket could make that much difference. Well done for realising
Enjoyable video, thanks.
yes floats can be fixed/resodered good idea is to find the spot where hole is ,fairly easy drop in a pot of water look for bubbles
then drill a hole and let the gas inside drain out and blow compressed air let it dry off you don't want to be making a brass hand grenade .then re-solder your done a fairly easy fix
Yeah tried it (and the replacement float) in a bowl of water but nothing showed, must be a tiny tiny hole
It seems to have been a combination of all those little things that made it go 'on strike'. Obviously the float was the main culprit I would suggest and the little spring going AWOL, the spring has sprung, made things go awry on the choke side. The gasket issue seemed a bit odd, after all we are only talking fractions in thickness. That one caused me a bit of a head scratching and I am still not sure why, I mean you haven't changed the volume of the oil, very strange! Does something press against the plate when it is in place? Anyway you seem to have cured the old girls ailments so maybe I am over thinking things. One more point, did I spot solder on one end of the old float or was that just calcification? The only reason I mention it is because that could be another possible entry point for fuel. It would be worth keeping it as a spare if it could be fixed I think. Thanks for the video Rick and glad all seems to now be well. 👍👍
The location of the top plate, and the gasket, on oil pumps like this is quite important, there's something in the back of my mind about even distortion of the plate can affect pressure. I'll certainly keep the old float and look at getting it repaired, throwing things away isn't something I do very often ...
I think you could have a point there with regards to distortion. It would be worth doing some research Rick even if only for peace of mind. Glad you are keeping the float.
Oh what happened inside the truck in your garage. Your voice sounded muffled. Like a dalek out of Doctor Who. Ha!
Yeah the audio went a bit weird for a moment
@@oldclassiccarUK I think the engine noise is overloading the microphone.
Seems like the dreaded ethanol has penetrated the old lead solder. Good result though. Just a tune up now, or a good drive and check plug colour.
"Dreaded ethanol"!!!!!!!!!!!!!!! Been used in gasoline for years..............
Could be, although I also suspect the cocktail of chemicals that also go into modern fuels might not help either. Or it could just be old age!?
Get some hottish water & immerse the float in it. Then you will know where the hole in the float is. It is then easy to solder back up. Obviously, you should be able to get the fuel to vaporize out with the warmth.
coil or ballast resister.😊
Not in this case!
Another great video . I think it deserves a Oscar. Should you start the little Dodge appreciation society ? Thanks once again👏🏻🤩🛻
