I have that soudn as well. A little trattling like a chain inside the heads.
None to worry about my mechanic said. Keep it under observation. I have BTW heard that on almost all 348s.
Tough to say what it is oin your case though unless you hear it yourself. That is why a qualified mechanic is a good thing.

Ken,
Advocating overfilling the dry sump oil system on a car you have no experience with is a bit irresponsible, no?
If one follows the level check procedure and keeps it up to factory prescribed level, no starvation-related problems will occur. |

Europas are notorious for oil starvation on right hand turns even in AutoX. We overfill 1 quart and no more problem. Can't say how much to overfill a 348 but the idea is a good one IF you get it right. No flames please if you froth your oil and destroy your engine. |

I've seen this too. Could definitely be the precursor to something quite expensive. If it happened after driving on the track at speed, oil starvation sounds like a good possibility. I'd play it safe and drop the oil pan, pop the caps off the bearings and check for damage. This will only get worse if you do nothing.
Track day checklist should include a couple of quarts of engine oil, and knowing the specific procedure to check the level for your car. For the 348, engine warm until cooling fans have stopped (~195 degF engine coolant, you may not see oil temperature), shut off engine, then check dipstick in the oil tank in the corner of the engine compartment. Add as necessary. |

I had this 20 years ago after tracking my old Alfa, it turned out to be main bearing shells destroyed. One bearing half shell had ridden around under the edge of its partner shell half, there was also evidence of associated crank main bearing overheating.
Cause was oil starvation, in my case due to a design with inadequately baffled sump (unfortunately it wasn't a dry sump design....my fault for tracking it, not the cars)
Hope momentary oil stavation and associated damage is not the case with your buddys car. |

Hi, Today I went to the track with a 348 and after 3 or 4 laps a strange noise appeared in the engine , the little clicking would go with the RPM. sounded like a valve. What do you guys think. The owner of the car thinks that it only a matter of regulating the valves. I am not familiar with the 348, butthe noise was a bit to loud to be only valve regulations. Please if anybody is familiar with the noise please advise of what it could be. We are in Costa Rica where there is no ferrari dealer so any advise from you guys would be very helpful.
thank you |
