Warmed my heart to see that 400GT running somewhat smoothly again! Hopefully the leaks cooperate and can be fixed somewhat easily, and the clutch job goes smoothly as well! Great video. Really shows your skill level and attention to detail. Can’t wait to see more! Thanks Tom
@@tomyangnet The rattling sound could have come from the engine due to bad ignition (there were some cylinders cutting out) it sounds metallic could be a combustion pinging or knock..I would change all plugs and check the wire harness too (dont forget the ignition condensers if it still has those, dont know if a dinoplex CDI ignition was optional on the 400 those can become faulty too and cause pinging, can be replaced with an MSD). A compression test would also be a good thing.

This car got to you just in time !!! Fantastic episode, that distributor drive is an expert based item, sounds strong on the test run, interesting finds with the 20cent o-rings. You have saved another one !!! Best regards for Christmas and the new year
The 400 presents in person far better than in photography. The 62-64 Lusso is the same in even more dramatic fashion. We had a half dozen of these new when they came out and I was always impressed by the coachwork - that double take affect. I don't think any of them were manual cars and I remember the automatic being a Turbo 400. Very cool.
I think these 400s are aging well. The creased angle designs of the 308GT/4 and this 400GT took some time for me to appreciate, but it's not weird looking like the Lagonda. The automatic versions of this model really made them into laid back cruisers. At least the 5-speed gear box makes this car more sporty!
Great stuff Tom. Always a pleasure to watch and learn about the appendices that make our glorious engines work as they should. Thank you. Merry Xmas Tom and wishing you a great 2025 :-)
Excellent work on a car you definitely do not see everyday! Especially with the DCOEs and not the injected model. Should be a great car when you're all done with it. Keep us posted!
Love that car. I guess one day all the cars you put right for all your customers will be restored and run perfectly as they will be worth a fortune. Glad we get to watch you fix them now. Great drive at the end!

@@tonysangwine-gould4733 it’s a slow process of degradation, and some people who have never driven a Ferrari may not even have known what its full potential could be! The power coming back though!
I recommend Bosch Platinums or Champion double copper plugs in those old cars...dont use the New multi Elektrode plus...those need higher ignition voltages
Even the platinums are a little overkill. I used to get simple NGK BP6ES plugs for a couple bucks a piece. Now the only ones that are available are the resistor plugs, but still cheaper than the Platinums, and you'll never reach the service interval!
@@tomyangnet With NGK here in Germany we have problems since they come from China....in carbed cars if they become wet with fuel or oil once (for example during start) they cut out and never recover and work reliable again...i think they are now made by Torch in China and with cheaper ceramics. Bosch and Champions work best on old cars IF they are made in Germany or Belgium or UK...they clean up nicely even when flooded with fuel...I test plugs in two stroke engines....you cant use any NGK of the newer series in a two stroke motorbike MZ engine they cut out after a few miles. The Bosch platinums with single electrode are expensive (NOS only made in Germany) but work fantastic even on clapped out oilsmokers ;-) Old Champions N 6 YC copper or the better N 6 Y CC double copper also work fine. Are you sure BP6ES are not too hot for the Ferrari? Originaly the cars came with heat grade Champion N 6 YC = NGK heat grade BP8ES. Autolite plugs were fine too when sold under Motorcraft brand for Fords some years ago.
Most likely not old enough to have had the distributors overhauled, might have come out if long term ownership from somebody who stopped maintaining it 20 years ago. I guess the biggest issue is they got to a point where they were almost worthless so people just didnt want to spend a lot on them 😥
I think because these distributors are not as easy to remove and check on a 400GT compared to a 330, they were left where they sat and slowly got worse and worse. Hopefully the new owners of these cars that appreciate the rewards of care and proper maintenance will bring these cars back to their former glory!
@@miamimo70 all the Ferrari 2+2s cost the same as the 2 seaters when they were new, so people did want them. It just took many years later for the secondary market to want them!
Love the 400! However, the last 400 GT I drove had a clutch that was ten times heavier than the clutch on a 330 GT - how heavy is this one? Also, that engine bay is terrifying, considering how packed it is! How many hours did going through the ignition a carbs take? And, more importantly, which choice words did you use getting the distributors/angle drives in?... :^)
I have found most of the heavy clutches on Vintage Ferraris come from hydraulic master cylinders. This 400GT has a cable actuated clutch, which seemed fine. I don't think Ferrari got the ratios right when they spec'd the bore sizes on their hydraulics! There were more than a couple dozen hours to get to this point!
@@cav4290 the goal of the tuning in that video was to assess if there were any major running issues before addressing all the other issues on that car. Since the car wasn’t driveable when I first got it, I didn’t know if the transmission shifted properly, the rear end was howling, or if the engine was knocking. The test drive you saw gave a good base line to start and confirmation nothing was majorly wrong. We’re now able to do the rest of the work without any major surprises. Video of the progress to follow soon!
@@tomyangnet The rubbing distributor cam follower plastic parts on the newer contact sets are made from a kind of cheap Lego plastic (look like Teflon but arent!) and wear off quite fast even if lubed properly, the NOS ones had Pertinax hard bakelite cam followers and those almost dont wear off, thats the reason we only use NOS sets by Bosch, Facet, Unipart, Lucas, Beru, Schier, Bremi, Magneti Marelli. They are all fine if not made after 1995....from early 2000s they started with that strange el cheapo plastic.
You are correct, but I was thinking of the particular cars. the GT/4s and the GTC/4s.

@tomyangnet Looking forward to it!
@tomyangnet How much did thr refurb of the distributora cost and what do you think of electronic points for this car?
Can’t imagine the time and cost!
30 hours so far! If you have to ask the cost...
Modern Chinese ignition Contacts suck i only use NOS Bosch
Many of the reproductions stink. You have to know which ones are better and stick with them!
@@tomyangnet The rubbing distributor cam follower plastic parts on the newer contact sets are made from a kind of cheap Lego plastic (look like Teflon but arent!) and wear off quite fast even if lubed properly, the NOS ones had Pertinax hard bakelite cam followers and those almost dont wear off, thats the reason we only use NOS sets by Bosch, Facet, Unipart, Lucas, Beru, Schier, Bremi, Magneti Marelli. They are all fine if not made after 1995....from early 2000s they started with that strange el cheapo plastic.
Looks like another Ferrari migraine coming on !
@@supersonique001 I pre-medicated knowing this car was coming in!
@@tomyangnet LOL! Merry X-mas and a Happy New Year.
@ you the same!
When you mentioned the models that have the DCOEs, you forgot to include the predecessor to the 400GT.... the 365 GT4 2+2 which also had the DCOEs.
I dont think he forgot. I really dont.
You are correct, but I was thinking of the particular cars. the GT/4s and the GTC/4s.
@@CarWizard Technically he did. Mr. Yang only mentioned the C4 and the 400GT. It is a minor oversight, as the C4 and 365 GT4 2+2 are very similar mechanically.
Looks like the Ferrari from Daft Punk Electroma
I have not seen the Movie, but I hear that was a 412, which is the last version of this particular model. Is it worth a viewing?
@tomyangnet absolutely, especially if you like their music 🖖
