Packed a lot of useful info into this short video. Thanks, Steve. BTW - Who ever had the brilliant idea to mount oil filters upside down? Looking at you, Ferrari!
MG MGC TC is another of the wonderful BMC cars I lusted for. I seem to remember that the exhaust note from this BMC in-line 6 was sooo nice to hear. I'm glad you showed this one,
I never tire of watching these videos. Even though the basic principles are the same for each car, it highlights the subtle differences to look out for with each car.
Well as you say Steve it is worth checking on a Dyno. We all thought this car was running fine having seen you drive it and I would think you thought that also. Another one checked for winter , thanks for the video Steve. 👍👍
Indeed, they are frequently unfairly maligned in favour of Webers. I looked at the flow rates and there's absolutely no reason to use anything else for most original fitment road cars.
Did a light restoration with new top and paint on my '68 MGC rag top I had back in the mid-eighties. I really enjoyed that car. A Brit, travelling around in the US, saw it and had to have it. He bought it, shipped it back to England.
I've been getting a lot out of videos like this one as well as the others in which you trouble shoot and eventually start a car that has been in storage. More please !
Had a MGC rag top in the mid-eighties. Did a cleaning and new carb kit on the dual SU's. Borrowed a vacuum adjuster from friend and sync'ed the carbs. Ran well.
My buddy had a 308 Ferrari with the upside down oil filter. The one it used had an anti-drain down valve inside of it. It would be good to check into that type of filter because the oil pressure takes so long to come up.
Actually, that oil pan does not look that bad. Healey owners use the oil pan condition as an auxiliary odometer, often more accurate than the one on the dash.
It's a lot worse than it looks on camera, any time the pans are bent to a sharp angle they tend to develop a leak and this one looks close to that happening.
I thought the MGC produced more power than that @ around 145bhp at 5,250rpm, with a torque figure of 170lbft at 3,400rpm, was the US spec car de tuned ?
Can someone explain the dashpots to me or point me to somewhere that explains them? Or are they simply just to damper the throttle butterfly? Does the oil seep past some seals and get combusted and that's why the dashpots need to be refilled periodically?
The dampers richen the mixture when you initially open the throttle. Much like carburetors that squirt in extra fuel like Holleys and Webers with a pump connected to the throttle linkage. With SU carburetors the oil in the piston leaks past the piston and always has to be periodically topped up. Without the damping you would get a faltering as you tried to accelerate
the mechanism (the piston and its needle) for enriching the mixture acts too quickly without the dampening, so... your guess is right. there is no seal, it's just a close fit and so a bit of oil gets past and is combusted along with the gasoline and air.
ya, i want more...if only so that i know your cars are in good working order. ha BTW, according to a quick perusal on the net, the MGC is supposed to put out 145HP. what's up with that? am i being fooled by the multitude of HP ratings/definitions over the years?
@@ThisWeekWithCars so it looks like there is no standard by which to rate HP...too easy to manipulate the numbers and make false and/or misleading claims. ...need a dictionary and encyclopedia to make any sense of it. or use only a comparison using the same testing apparatus and conditions. a perfect example of the advertising community and manufacturing moguls conspiring to make a standard metric into a farce.
Massive envy at you having the space and means to have your own dyno. Just Brilliant. Well done.

Another outstanding Winter Checkup video!
Thank you!

Outstanding video and presentation. Beautiful MGC Gt.

Another well made and informative video. Who doesn't love a pair of SU's gulping down air?

You have all my bucket list cars. Great collection.

Thanks for showing us, Steve!

Excellent Video Steve :) very good 👍 information and especially on MG cars too! I be looking forward more too Steve on Dyno Test so cool!
Steve . You really enjoy yourself "tinkering" with all of your cars . Great stuff !
For any older car owner, your advice about not relying on the seat of the pants feel is very important; the dyno doesn't lie!
YabbaDabbaDOO -- More Great Info provided by YOU. Thanks So Much for Making These Videos for Us Steve.
Great tech work. I gotta say I don’t miss syncing the SUs on my old AH 3000 BT7.

best and most real classic car channel on YT>
Another great informative great video on a beautiful car. Thanks Steve.
The '68 MGC I had in the mid-eighties had the original Smiths guages which worked fine, suprisingly.
Thanks
My buddy had a 308 Ferrari with the upside down oil filter. The one it used had an anti-drain down valve inside of it. It would be good to check into that type of filter because the oil pressure takes so long to come up.
What a fun-looking car! I bet with that 6cyl engine it really goes.

great stuff thanks
More of these "hands on" video's please
Brilliant 🙏
Great looking car!
Really fun checkup. Biggest shocker: two GALLONS of oil?!?!?
Great video Steve! I thought that 6 cyl would have much more power than that! Also the speedo has a digital odometer. Must have been switched!
10:15 I mean wow, syncing the carburetors?! I had no idea.
That upside down oil filter must have seemed like a good idea at that time.
3:50 To a classic car owner, the few seconds before oil pressure build up feel like eternity! 😬😬
very useful
I thought the MGC produced more power than that @ around 145bhp at 5,250rpm, with a torque figure of 170lbft at 3,400rpm, was the US spec car de tuned ?
This is rear wheel horsepower, also old horsepower numbers were given at the engine with no accessories on it.
FWIW I installed a magnet in my oil pan plug (1968 MGC roadster)
I want that car (or the Morris Minor pickup!) / btw, Steve, it’s an MG “C” GT. The MG model is “A”, “B”, “C” not “MG MGC”
What is the capacity of this engine Steve? A straight 6 has got a great sound of its own!
It's a BMC C-Series at 2.9 Litre
Specs say 145 hp 170 torque so is that the not corrected or drive line loss or just MG fudging the numbers or maybe e all the above
Oil pressure seemed a bit low & slow to come up. Is she tired?
Can someone explain the dashpots to me or point me to somewhere that explains them? Or are they simply just to damper the throttle butterfly? Does the oil seep past some seals and get combusted and that's why the dashpots need to be refilled periodically?

With SU carburetors the oil in the piston leaks past the piston and always has to be periodically topped up.
Without the damping you would get a faltering as you tried to accelerate
Another great video. I’ll add the air pressure trick to my list. Did you check the transmission and differential after the video?
the mechanism (the piston and its needle) for enriching the mixture acts too quickly without the dampening, so... your guess is right.
there is no seal, it's just a close fit and so a bit of oil gets past and is combusted along with the gasoline and air.
What did the AFR results look like at idle, partial and WOT?
Yes that is a race car Peace out
ya, i want more...if only so that i know your cars are in good working order. ha
BTW, according to a quick perusal on the net, the MGC is supposed to put out 145HP. what's up with that?

Not seeing the oil pressure register for over 20 seconds when he started the car made me cringe a bit 😮
That will be the oil filter filling…
Only 78hp from a 3 litre?
What was the tool you used for the carb balancing?
