Technical Barchetta problems

1. Not sure why it starts badly, could be fuel vaporisation.

2. I use Selenia 20k which is a 10w40 synthetic based oil.

3. What year is your car? Early cars used different plugs.

4. You either need to adjust the cables by the handbrake or replace atleast one of them.

5. The wobble you hear could be a faulty wheel bearing.

6. My car doesn't have this rectangular plate you speak of.

Hello,

My B is from 97.

About the fuel vaporisation... i saw a small white valve one one of the blue tubes (gas) could be that one obstructed?

About the wobble... i know the sound of a faulty bearing... (i changed one :). This is a constant sound. May be the sound of the tires or the sound of a moving exchaust... Anyway... as i told before... i don't know how's a normal B.

Is the gear shifter vibrating at idle speed?
let's not talk about the stalling... (i cleaned everything i found dirty).
The brake hard or too hard... It's not throwing me from the seat like the other car i have.
Vibrating shields (i don't see the cracks)


Thanks
 
The spark plugs you should be using are NGK BKR6EKC.

I have a later engined Barchetta so can't really help on the fuel supply issues as it is different.

Thanks anyway...

I discovered that the left back caliper it's half blocked cause of the hand-brake. it's not about the cable... it's that thing on the back of the caliper which blocks the wheel (pulled by the cable). It's at the middle.
I don't know what to do :(
 
Hello Everybody, I just bought a 1995 Barchetta and hope someone out there can help me troubleshoot a problem with it; it runs fine but when at idle the engine is very loud, it actually sounds like a diesel (I keep getting asked if it is a diesel) but then at around 1900 RPM it goes quiet. Oil levels are fine, engine idles steady, i have no (noticeable) power loss, it's just noisy and really annoying.

Any Barchetta owners experience this? :confused:
 
Yup - most B owners experience it :) Do a search for variator on the forum.

Change your variator and you will never hear it again! (y)
 
So the simple rule of thumb must be, if your changing your cam belt, change the variator at the same time, possibly the water pump as well, maybe once every 2 cam belts?

hey,

In the last 2 years I used Castrol Magnatek 5W40... and the diesel sound was there for 5 sec after starting.... I changed the oil and I put Selenia 20K... and guess what... No diesel sound anymore.
;)

I have a question about the braking system... I changed the braking fluid, the pads and disks... And now I have to push harder the pedal to stop the car... did you experienced this?

thanks

I have a similar problem, the brakes are borderline for an MOT pass.

They still work fine, balanced fine left to right and can still kick the ABS in easily enough, you just have to push a bit harder than in my other car.

Selenia 20K is a 10W-40 oil so is a little more viscous than the magnatec 5W-40 oil.

One could argue that the 5W oil will drain down quicker but pump up more quickly. Conversely the 10W will hang around longer but take longer to pump up.

Many Fiat dealers now use Selenia Performer, a 5W-30 oil. Our 'B' was noticeably noisier in the variator area during the last dealer service interval.

I replaced the oil with Mobil Super-S, 10W-40 (ie. Selenia 20K comapible) and there was an immediate quietening/cessation of the start-up variator diesel rattle.

I'm going to see how things go. Will be due for a cam belt change, probably late this year/early next, and decide then if I need to replace the variator. Our 'B' is age driven on the cam belt change. We've already just past the 5 year mark but with only 27,000 miles on the clock. I'll probably push to 6 years, (yes I do periodically inspect the belt) but then have to decide if at only 36K miles or less on the variator whether to risk not replacing the variator when I do the cam belt. For the cam belt and tensioner only this is a quick straight replace. I know the cam belt has never been removed and changed having owned the car from new, runs well, so I'll probably bypass all the came cover removal, shaft locking etc.. If the variator then seriously plays up at a later date then I'll bite the bullet then.

As discussed elsewhere I may look into doing away with the variator altogether. Will probably cost me the same or more as a variator but I quite like the idea of a good old vernier cam and then will never have to bother with the variator again.
 
@S130:

5w40 oil is only thinner than 10w40 when cold. Also, it's common for the belt to be ok but a tensioner to fail, causing problems. I'd change the belt and tensioners now if I were you.

I'm fully aware of the tensioner breaking up before the belt lets go.

Crazy design.....

The tensioner on our Strada Abarth is over 22 years old. Still solid as a rock and noise free. Bearing spins smoothly & freely.
