It happened a time ago, that I started my 328, and a loud ticking noise came out of the engine! ticketicketicketick.... It came from above; at the upperside, right. It frightened me! But after 20 seconds it became a little less, ticketicke vroemvroemvroem ticketicketicke, and after another 20 seconds it was half, and became less and less. And after 2 minutes the sound was gone. i don't know what it was, but i've heard later, that is has something to do with static electricity?? Where? Howcome

did you have the airco running? the compressor belt in known to produce some ticking/wining on startup

Heey Bram. No, I did not have the airco running. My gas is out of it (I have to buy new gas in belgium, because i cannot buy that gas in holland). But the ticking came from overthere, yeah. When you stand behind the car, on the right side, on top of the motor, almost near the rear window. Is the compressor belt somewhere over there

Sorry about that - let me rephrase: switching on a (working) airco will produce a somewhat sizzling sound, but the airco-belt is constantly driven. Still the most likely source of your mysterious sounds, I guess.
Why don't you take your car to Alex? He can pressure-test your system and fill it, adding ester-oil (sp?) for lubing the compressor. No big deal, wouldn't try to hassle with doing it by myself

Does it sound like glas marbles going around in a cookingpot?
That is the sound my 308 makes when starting cold, disaperes after about 15seconds.
Some other 308/328 i know do the same.
Don't know what it is buth i've driven my 308 for more than 40000 km with this.
And i don't spare it, i drive on the circuit and top speed on the Oberhausen straight
After some deliberation i desided to take the airco pump out of my car.
It was out of gas, it hadn't worked as long as i have the car, i was not going to repair it, it could only go wrong.
An other reason was that de noise the car made got worse now not even at start-up but especially aroud 3000 rpm. and i thought the compressor was the culprit.
I have to say it was a hell of a job to get it out without taking de waterpipe or fueltank out of the way.
It took me a few hours of tinkering than i got it out.
After startup no strange noises anymore, not even at 3000 rpm or higher.
Had it up to 7000 rpm, sounds glorious.
Just a heatshield ratteling that i forgot to tighten up.
Next thing i'll get out the condensor that is in front of the radiator.
A friend of mine did this and he told me that the radiator worked significantly better

Sounds like it might be the electro-magnetic clutch acting up. What did/will you do with the hoses running up and down the condensor

Nothing.
I've closed them of and will leave them in place in case i want to reverse it

So you are driving now without the airco-pump JW. Actually, no problem of course when you never use it. I always drive with no roof, so it doesn't bother me either

In my 328, US version, it is the EGR system that has a small leak. If the engine is cold you can hear a sizzling noise, when heating up, its gone. Its only by the US versions, to reach the US emmessions standards, the system is blocked now, and the noise has gone. The system is a construction of small steel pipes, for each cilinder there can be measured the co2 exhaust. It has no meaning for Europe, it is only to stand up the Californian standard

Interesting Kees! Didn't know! Are there more differences between US en EU version
might it be that when the airco pump has not been used for a longer tome the noise will start due to lack of lubrication at whatever area or seal rings beng dry too lon
in an other threat we are still looking for help how to refill the old airco system.

Robert, is this than the original R12 or.

Robert, is this than the original R12 or..Yes I thought so. The 'old' gas anyway (which in holland is no longer allowed

Yes, to change your sparkplugs, there is almost no space for the row behind the rear window, US versions have a metal plate, to avoid heat in the interior, it limited the space to change the sparkplugs with abouth 2 centimeters, and there is in an Europeon Ferrari almost now place to work on it at that side. Beside that, European Ferraris have abouth 270 BHP, US en Switserland Ferraris only 240 BHP, all because of the enviremont regulations..
Yes I thought so. The 'old' gas anyway (which in holland is no longer allowed)
thanks, I will have to go for for it than in Belgium
