Ferrari 308 Rebuild - How I Narrowly Avoid a Disaster 

You've just won the in-video advertisement game. LOL, don't know how you got your wife to agree but it was worth it. Still laughing. Well done!

Mate that’s the only in-vid ad that I’ve genuinely enjoyed. Well done to the lady for having a good sense of humor and pulling of off with comedic excellence. The smoking bush was just 👌🏼👌🏼👌🏼 🤣

Hi Doc here from 'TheHelidoctor' I'm hearing what sounds like very noisy belt tensioner bearings or worse still cam belt pinion drive bearings. Now it may just be the sound on the video but the engine does sound very 'dry metal' and noisy. Before you run the engine again I'd pull the belt covers and see if the belts are going slack on the long side. Also is there any play in the tensioners and or belt drives off the crank.. Now I know the belts are under tension BUT if you rotate crank back a few degrees you can sometimes feel any issues that way. You say you are doing a belt change, well this is great because once the belts are off you MUST see if there is any play at all in those drive pinions....they are know to fail and then then engine goes bang I'm afraid. Obviously replace the tensioners and check the water pump also. Really like your channel, good luck kind regards, Doc

Your Manscaped adverts are still the only ones I'll sit through, well done.

Brilliantly entertaining and informative channel. Don't car manufacturers just *LOVE* to invent unnecessarily new or bespoke designs for bog standard components.

Yet another master class & piece stunning loving the channel👍✔️

Amazing. You’re the ultimate problem solver!

Btw. I’m so psyched up on a potential recycler resto mod rebuild of a F 40, I’ll be glad to see the 308‘s gone so that you can finance 512 BB build and segue into the F 40

I really enjoy your videos, they just keep getting better. You have a very understanding wife stripping bits of Ferrari down in the conservatory!

Liked just for the manscaped ad 😂

Scott, perhaps small tip, glue some small magnet on the back of the psi meter. Now you can put it on some metal part 😄

Good video, like always. I always watch as soon as they come in. Thanks for helping lou trottier from Canada. Have a good day Scott.

My good god, that is one hairy bush!

You and Lexi’s adverts are so ridiculously obvious, I find them brilliant. LoL but that deer in the headlights look is the best delivery ever. Really enjoy!!

That manscaped advert should be on TV

I always learn valuable repair information from your videos!!!! Keep up the good work. :)

Hat off for Lexi! Great performance!🤣👏 The horror that is K(E)-jetronic... (in combination with ethanol in fuel.) To keep that system reliably operational you got to keep USING it.

Love the way the Manscape adds are delivered " Great marketing" I think the 308 looks great in this coulor ? Shade tree mechanics in action lol

Top fault-finding and diagnosis - well done. Your presentation style makes it great viewing 👍🏻

Probly cold start injector they are well common for holding open

Hahahaha love your manscaped adverts, about the only in video adverts I watch lol P.S you really should setup independent Ferrari service company… you’re probably better than most main dealers

when i seen the smoke coming from the bathroom i assumed she was going to town on her clam....

16:10 Your Ferrari sounds like a bag of spanners 😁😂🤣😂 Seriously tho', great diagnostic work and fix, well done! 👍

A ultrasonic cleaner in your garage would be a good addition for jobs like this 👍

It's like a treasure hunt, another clue then the big payoff! Keep up the fun work!

Love all the "debugging" process, very informative !

Getting there ... Still want that 308! (seriously) Keep On Keepin' On Great stuff! Ciao4Now 😎

Had a vw fox that I had to drive pulling and replacing the fuel pump fuse to get to the shop. They spent a few hours trying to diagnose why it was flooding. Turns out even though it's a mechanical fuel injection system it does take a single sensor input. The coolant temp sensor failed and was double the resistance flooding the engine. Worth a check.

Lucky your rear end wasn't toast!

Never mind the weeds, the placement of the jack by the side door so you can actually operate the handle is genius!

Bosch k jetronic. I have a very similar set up on my DMC. Had to go through it in the same way you are. A word of caution to anyone removing the fuel distributor. Be careful if that piston isn’t seized it can fall out and any damage to it is bad news. I’ll be interested if you set K-Jet up with a dwell and CO meter on the Ferrari as you do on the D.

Sadly from 2030 on all combustion cars including classics will be banned from all public streets in entire EU and Scandinavia :-( In Germany the Green Peoples Party gave order to shorten fuel supply from 2025 on by reducing all conventional fuel stations to only one state operated central gas station per city or county. From 2027 on in the EU certain car spare parts will be banned too....as exhaust systems, turbo chargers and even some engine and gearbox oils...California and New York will do the same from 2027 on.... So no investments should be done in oil burning cars any longer....They even created a new kind of crime here, called emissions and smoke criminality......

If that fuel pipe was so rotten, couldn't the fuel return pipe also be similarly deteriorated, to the point where the return flow could be blocked and end up getting pushed into the engine? Just a guess!

Never mind the weeds on the driveway mate……suggestion…..get yourself a good workbench. Pull out….fold down….fixed…whatever!!!!! But please stop using the other Ferraris as a work surface. How about a nice trolley type with wheels underneath that you can tuck away into a spot. Goodness me!!!!……..I’ll even consider sending you one from South Africa 🇿🇦

Hi mate I really enjoy your videos. I can't afford to collect cars but i do collect early 80's BMX. And they are getting crazy with the prices. Love the bmx in the background. GT?

My 2p worth . . . Thoughts: a filter before the pump would be nice, how about fuel pressure- is there a fuel pressure regulator? around 3 bar is normal, on some bikes that I have worked on the fuel relay and the ignition relay look the same but they are not- new relays ! ?. . and of course all new fuel and vacume pipes with E10 spec would be a good starting point, I use a length of rubber fuel pipe to help get plugs in/out of deep tunnels, I can't really imagine that Bosch hardware would be faulty (( looks like I have too much confidence in Bosch ; )), also relatively cheap to replace all the sensors, such as air temp, water temp, throttle position, map sensor etc, (something is obviously affecting all cylinders, whatever), good luck- I am mentally 'with you' on this. oh yeah and the manscape ad is superb, really your sister ? ; ))

Well done mate! Did you accidentally put (or got scammed into putting) E10 petrol in there by any chance to cause all these fuel issues? To state the obvious, E10 is really bad for older cars and your problems (and worse) are common results of putting E10 in a car that can't handle it.

Great videos. Where did you buy the fuel distributor repair kit from? Thanks.

Thats why most Ferrari owners have a Porsche for driving. But she looks beautiful 😍

I couldn't quite see the inside of the fuel distributor when you opened it up. Does the vacume from each cylinder cause the valve for each cylinder cause it to open each valve allowing fuel to be sucked in and then the coil spring closing it again when the vacume releases it? On other news: a cave drawing was just found in France showing a cave man entering his cave with a haunch from a brontisarous telling his woman to cook it up while he runs further into his cave to shave his balls. We guess cavemen were more civilized than was originally thought. Lol

Looking at all that trash in the rear storage compartment has my OCD in overdrive

Pathclear spray 👍😂 Good with cars Useless with weeds

I think I would be replacing all the fuel pipes. The one yo cut open looked terrible, the others are the same age so will probably be in a similar state.

I'll never skip one of your Manscaped adverts. Never.

Are u in advertising or commersials by any chance? Seems your alley!

Great vids

Thank god we have EFI these days what a nightmare!

Yeah my guess is leaking or stuck injector, had a mk1 golf gti would do a similar thing especially after sitting for a bit.

there is a very long Alan key to adjust the idle mixture through a tube on the top with a black plastic plug you need to remove..Capri 2.8i Granada 2 8i and xr4i and xr3i 4 cylinder. set the throttle air gap small screw with lock nut and adjust the idle by pass valve big screw then adjust the mixture with a co2 exhaust meter

😂😂😂😂 his wife is super fun

A close shave with the Ferrari then.

Injection system looks almost the same as by Golf 1 GTI with DX engine.Easy to diagnose and repair...

no bush too tough. Or scaping the lady garden.

That metering head looks very simular to the old Bosch KE Jetronic as used on the MFI (manual fuel injection) mk3/4 escort XR3i & RS Turbo the U.K (later replaced by the EFi system)

Nice work Scott

I hate those fuel distributors..I'm trying to get my 1985 Mercedes to run it's got a similar fuel distributor.. They're a nightmare.

I like the chrome an gold look on the old bmx . im watchin on my phone so couldnt make out the make but i do dig the black skyways. Oh an the lade back post allways a nice touch .

The Lexxi Manscaped promo is a whole other video me thinks..😋

Great content Scott I’d watch you 24/7 working away methodically on any 308 just such nice cars here’s to the next one 👍

Who’s signature is that on the steering wheel?

Did your rebuild kit include a new diaphragm disk for the fuel distributor? sorry if I missed that - I used one of those sets on my Merc W123 and the big rubber disk had somehow gone floppy and brittle so wasnt working at all

Best way to fix a Ferrari? Have another Ferrari…

Great work as always sir! Your good lady is just minted. A treasure! Thank you for the information and the smiles! You and yours stay safe and well!

Funny manscape bit. Loved it. My son just calls me Graybush and I leave it at that....

Maybe 2 hood struts???!!

Is that an old GT bike with the mags on it ?

Man can I have one those 308s , I’ll make ya payments , I’ll never be Able to buy ,drive or afford the worst Ferrari in the world , love the channel

Awesome

Some times the simple things cause the biggest problems. Love your work.

Will you be able to cope with E10 or do you use super unleaded?

Almost there, will be great to see it on the road again!

The greatest ad ever. Almost made me buy one. Hahaha.

I have heard a lot of people, Car Wizard included say they don't go near working on these fuel distributors. Your no fear, get stuck in attitude is fabulous

U do a awesome job and u have a lot of patience

Scott... You definitly are a CRACK of LA BELLA MECHANICA. All my respect from Montréal, Québec, Canada.

I have nightmares about owning a Ferrari after watching your videos. I had an old Jaguar XK120 and never had any of these problems.

Aloha from Hawaii. Great video! Ive always wanted a 512TR but After seeing you being a contortionist troubleshoot this 308 GTS, i'm very happy having a 2007 Z06. Keep it up.

Love the vlogs brilliant info 👍 Especially love the Lego 2018 AF CORSE Ferrari Le Mans 🤣 was there that year myself and 2014 think we camped just down from yourself in annex houx wish I had found the channel before then as would loved to have said hello 👋

K-Jet is an absolute pain once the system blocks up. Cars with this system must be driven at least semi regularly. So this car gave back what was deserved. You may well be in for a set of injectors. They are bound to be blocked to various degrees. A new set always improved things on my 911's.

You should add #k-jetronic, this also is relevant for early VW/Audi injection. GTI's used a 4 port system

Talk about the most over complicated car typical Ferrari over manufacturing

I noticed you propping up the boot/trunk with a broom handle. You can use vice grips on the strut to hold it open as well. Great video as always .. keep it up Scott.

Nice to see the Lego Ferrari buddy in the background 👍🏻👍🏻

I knew it was flooding as soon as it worked w/o the relay. I had an Audi rally car with this crap Bosch system that did exactly the same. I ditched back then and put a whole real EFI. I know you can't do it, but saved me a lot of headache and no more crazy cuts/over revs when hitting bumps which is quite common in a rally stage. LOL.

Great Vid' Scott lots of info..

Always an enjoyable video. That's way I stick to late Ferrari's now.

A plug remover for the front bank came with my 328. Made it easy.

I still wonder what is the most reliable mainstream brand in sports cars, previous to the 70's. May bet is Mercedes-Benz, or Porsche.

Check the control pressure to the warm up regulator!!! This is step one on K Jet cars. The top connection in the center should be going to your warm up regulator. That's the pressure on the head, and it puts resistance on the plunger. Cold start injector runs off of system pressure on the side, next to the system pressure regulator. System pressure and control pressure are different. You should have pulled the injectors first

No such thing as a small fire with that fuel distributor dumpling high test though the engine at 5000 rpm. Very bad with a secondary open for one bank.

You should get some wd-40 on that puppy. Would clean it right up.

K-Jet is a pain for sure. I've been through all of this on both a 78 and 83 E21 BMW years ago, learned a lot. There are shims in the fuel dist that are different thicknesses and affect the-control pressure? Long time ago...You will still need to adjust the mixture, I can't recall seeing you do that. I'm assuming that the AFM has that adjusment in Ferrari's implementation of K-Jet? Also, a great book is 'How to tune and modify Bosch Fuel Injection'. Covers all forms of K-jet, L-Jet.

Once again, the ad risks being the best bit of the vid. Edit, just to add that it isn’t :) Cracking vid, amusing ad. Good combo.

4 years not running? Would it be entirely not proper to think the gas tank is fully of stinky manscape debris and sludge, thus not being able to trust the state of EVERYTHING downstream on the fuel injection system. I'd rather rebuild 4 webers...and a fuel pump.

The CIS is a fuel sprayer system, not a fuel port injection system, courtesy of BOSCH. This is how the automotive industry limited engine to 25% over the last 100 years.

A very similar unit was used on 70s and 80s Porsche 911....they tended to backfire through the airbox and break it from the pressure. an aftermarket pressure relief valve solved the problem.

I like the steering wheel on left side, not because I think it's better but because I am less confused because I am from the USA.

Loved the video 🇮🇹😘

Brilliant video Scott, does your blue tint on your glasses help with anything? I've had big trouble with my eyes, got fibromyalgia one of the parts of it is I'm massively hypersensitive to fluorescent and LED lights which makes me very ill, nearly killed me once, they make thyroid & blood pressure go haywire? Now my eyes are always sore & dry if I look at my old phone. Thought the blue tint might help

Working on the 308 is way too similar to working on the Fiero.
