Steve- Yes, I removed the vacuum line so the flap would stay open. I wasn't sure if w/o the pump working, if the gas vapors trapped in the air box would "load up" the plugs or cause hard(er) starting problems. If you think that keeping the flap closed will not do any harm, then I may just reconnect the line and prevent more emissions. I'm all for clean air. Heck, I still have my catalytic converters on, but no muffler. But,my air pump belt has also mysteriously disappeared. Henry | ||

Thanks John for looking those up. Tom and Steve are right, they all relate to emission control in one way or another. As for the vapor, I have no cats, no smog pumps, no air injectors, no carbon canister.....do you guys think maybe that's why the "smell" (exhaust or vapor) from my car really stinks? It's OK out in the open but I can really smell it in an underground parking garage when ventilation is not the greatest. Like maneuvering into a parking space for a couple of minutes. | ||

Of course the older cars don't have a flap, and vapors at shut off just..... Uh, never mind. | ||

Henry -- That little air blower to evacuate the airbox is a pricey item (even at FerrariUK). (Please correct me if I've misunderstood, but) If you've removed the vacuum line to the actuator controlling the flap on the airbox snout, then the flap will just naturally stay open all the time -- which isn't a big problem, but it's not necessary either IMO. Even if the air blower has failed, I don't see why a working airbox flap system would be a problem (i.e., if just the air blower itself is dead, you can leave it all hooked up without a functional problem). The fuel vapors in the airbox won't be "pumped" into the charcoal canister with a dead air blower, but deliberately leaving the airbox snout flap open after shutoff (so benzina fumes now more vigorously waft out the RH side coachwork "hole") doesn't seem like it would help things. JMOs. | ||

Stewart, I have the same set up on my '78. Still plugged in but at this point I don't think it makes much difference. The sensors are still mounted to the back of the car also. Mine is past the cutoff point and all of the E gear is missing so no big. DJ | ||

Sounds like these are all smog related... My emission control system are pretty much all gone anyway.. And my car is approaching the age cut-off so it would never need them again. I guess I will keep them plugged in just in case it is for something else that I am not aware of. | ||

Stewart- Where have you been? I thought that my '78 308 GTS/B/O only had 2 white units. Yeah, I heard they were for the sending units that go to the catalytic converter (the slow down 1-4 or 5-8). The questions is if the "slow down 1-4" comes on, how do you slow down cylinders 1-4 but keep driving 5-8 hard ;) Steve- How important is the evacuation pump? Mine died years ago (as I'm sure just about everyone elses). I've just disconnected the vacuum line to the flap in the air box. I've always wanted to get a working pump so as to reduce the hot soak emissions but don't want to spend an arm or a leg to do it. Henry | ||

I was just kidding when I said "I'll just toss them out" (see the ;-P?) But whatever they do, the car did run without them. But I will plug them back in when I put the car together again, just in case it is for the ejection seat or something... | ||

NEVER toss useable Ferrari parts! Somewhere there's likely a F* owner desperately trying to locate them. Post them on the F*chat, or put them up for sale on eBAY. BTW, It's a good idea to hold onto all emissions gear in case you ever sell the car to someone from one of the states with a clean air gestapo like CA. | ||

Stewart -- What year is your 308GTO  (it's not in your Profile!)? I know the '78-'79 also had a "timer ECU" in the pass. footwell to run the little blower motor that evacuates the airbox fumes to the charcoal canister for a few minutes after shutoff. | ||

Don't toss them out. Someone else may need them. There should be 2 white control units. These are the cat thermocouple control units. The red one is a tachometric switch for solonoid valves. The black one I can't remember right off hand. Nothing to do with a turbo. | ||

Oh, there seems to be a box missing next to the (#3) white box. What used to be there? Maybe that explains why the turbo is not working.... :-) | ||

I am on a roll to clean up the interior of my 308. Today I pulled out the kick panel in the passenger foot well. When I turned the panel around, I see these 3 boxes mounted behind the panel, with harnesses plugged into them. Can anyone tell me what these boxes are (1,2 & 3)?  I'd figure if they are not important, I'll just toss them out ;-P |
