Hi Sandra, your friend is right, and you will fine that when the engine oil is a MAX ( dipstick ) the sound will be much less. It's also a good indicator when your getting low on oil. But you could need a valve job too! (shim) Lamont |

I experienced a tapping noise at cold start which ended up being the water pump going bad. '80 308GTB |

Sandra, Look again in the discussion and you will find the question "308 taps loudly on start up." Mine has done this also in the past.It's an irratic metallic snapping noise. I've heard that it can also be the diodes going bad in your alternator. I lost mine last year! I let the car sit for two month's and it started tapping again. I'm going to try what they suggest with the belt dressing. If I start it weekly it won't "tap". |

ANY EXPERIENCES WITH A "KNOCKING" NOISE WHEN THE CAR IS VERY COLD AND WARMING UP? EXTREMELY COLD WINTER IN PANHANDLE OF FLORIDA THIS YEAR (YES WE ARE BABIES) NOISE STOPPED ONCE ENGINE WARMED UPL. PAL SAYS ITS THE "LIFTERS' GETTING WARMED UP. IS THIS NORMAL? WHAT CAN I DO TO HELP
P-S 3O8 GTSI RAN GREAT AFTER WARM UP;. DID NOT DARE DRIVE IT BEFORE NOISE STOPPED |

He does raise a good point, I check the oil and coolant everytime before I leave with the Ferrari which is almost everday in the better weather months. |

Just a sad story to be aware of.... I cooked the engine on my Escort one day. The thermostat/gauge sensor is high on the engine. The bottom radiator hose blew, dumping all the collant in seconds. Well guess what... No coolant touching the thermal sensor and the temp gauge says everything is fine! Two minutes later, engine chugs and stops. I wouldn't want to have done this on the Ferrari! I always am aware of the collant level and check hoses and leaks! |

If you have a little too much cooland in (Ferrari recommends 6cm below the cap on the expansion tank is where it should be filled to) then when it heats up a little it will leak out of the overflow. I keep my cooland a little higher than recommended so when I'm moving none overflows, but if I idle for a few minutes it will spill out some. It's not bad that it spills some as long as it doesn't cause a significant temperature increase. The coolant systems are pretty good though, even if there isn't any antifreeze in the expansion tank there is still enough in those huge lines to keep the engine cool. Hope this helps some. |

P.S. If your cap seal was damaged or not seating properly, you could be running you car at reduced coolant pressure. Since the boiling point would be lowered, coolant could be getting to hot, expanding too much or boiling out. If this is true you may want to start with a new cap-- watch to be sure you get the right pressure rating (relief). |

The overflow only blows coolant when the pressure is exceeded -- very hot conditions. If you look at wher the hole is for the overflow, you will see that the cap seal is actually below it. This means that the only way coolant can come out the overflow is when the seal is lifted against the spring --- excessive pressure. A lot of vehicles will blow coolant out over the cap relief. Later cars have coolant recovery tanks that capture this coolant and allow it to be returned to the pressure sealed system.
As long as you're not losing excessive coolant you should be OK. |

Here's my theory for now. 6 months ago I couldn't change my oil, but I'm gaining confidence after taking auto tech courses at the local community college. The last semester was just on saftey, tools, reading schematics, and trouble shooting. This next semester is all on brakes. I think there are like 12 courses in the curriculum. Anyway, back to my theory... the car was fully warmed up and parked for about 10 minutes while running. It was parked up hill and since the enigine wasn't getting air to it, I think it was heating up and coolant was leaking out the overflow. The overflow is at the back of the coolant resevoir and because the car was up hill... it may have run over.
Does that sound right? |

Where was it leaking? Front of car? Rear of car? Can you see/feel damp hoses in the engine and/or rad? Check the tightness of the hose clamps. Rubber creeps out from under the clamp, so a few turns on the clamp should seal it again. I've noticed on my GT4, when I took the cooling system apart, one of the pipes had a big gouge in it (not broken through-lucky)! It was the pipe running from the "Vee" of the motor down alongside the bellhousing. Turns out that it was rubbing on the clutch return spring bolt. I'll have to fire up my TIG welder and weld on a patch. Plus build a bracket to hold the pipe away from the bellhousing. This is a worst case scenario, but not isolated! Put your coveralls on and get under your car!
The oil will settle into the sump from the oil cooler and a bit from the filter. I've always checked the oil just after I shut the motor (oil is still within these systems so it hasn't drained back into the sump). But yes you should check "cold" oil. At that point, my dipstick reads about 1/2 inch above the max line. When I drained oil from the car a few days ago, I had about two litres less after 2000+ miles since my last oil change. |

I noticecd today that my car is leaking a little antifreeze. This was only when I was parked for about 10 minutes on a slight inclinde. I've never noticed it before. When the car is cool, I can just check the coolant level, right?
Also, do you get accurate readings when you check your oil. My oil level is always up above the max and it has been 700 miles since my oil change. I've heard the Ferrari shop manual recomends a quart or so every 700 miles, but I haven't seen any level change or is my stick reading wrong?
Thanks. |
