What is this in the engine bay

Well that's strange. What is the other end connected to, or where is it going? Looks like a vent hose of some kind, but nothing down there it would attach to. Maybe it fell down from up above?

 

It's designed to blow cool air on the CV joint.

 

and without that $2 dollar tube, you need to replace the CV boot every 2 years

So the opening is for cooling the cats or cv joint, and has nothing to do with my high oil temps, right???

It the gauge is reading correctly, what else could be causing the oil to heat up so much...especially since the water temps are fine?

To cool a CV joint? SERIOUSLY? Never heard of CV joints overheating unless the gaiter has torn and allowed the grease to be thrown out. If that thing is really for that purpose then those EyeTies are even wierder than old Limey motorcycle designers!!

 

No need to cool a cv joint - unless perhaps you're involved in WRC...

 

To be a little more specific...

There's a spot back and under there on the 308 where the lead pipe from the forward bank comes very close to both the differential and the inboard CV joint on the passenger side. The area is not well ventilated, so the exhaust pipe tends to make temps pretty high there, and the duct blows fresh air into this location to try to cool both the diff and the joint boot ----- doesn't work all that great though. I added a heat shield around my pipe a while back, tossed the duct in the trash can, and now I don't have to replace that cv boot until it wears out "normally" .

This is not on the earlier carb cars so we must not have as hot of an exhaust , HAHAHAHA

 

LOL! Well I'll be darned! OK, from now on if anybody tells me that Ferrari's are better designed than Fords, I'll just show 'em that picture!

 

Changed the cam belts and tensioner bearings Saturday with another fchatter and we were joking about the tube and what it would cost from ferrari. Does not do a good job, my car also needs a new boot. We came to the wrong conclusion it was just to try and cool the entire engine compartment somewhat. He has a '77 so his car does not have one.

 

Once you find the temp sensor pull it out, rig up a ground wire and dip it in a pan of very recently boiling water. If you don't get 100C/212F, keep on working on the circuit. If you do get 100C, then put the sensor back in and find out why your oil is getting so hot.

308GTB/GTS: Table 17 - LUBRICATION SYSTEM (308 GTS AND AUS) shows a thermistor right in the neighborhood of the shifter input on the front of the engine. I would guess draining the oil first before pulling this out would be a good idea, or at least be ready with an adequate bucket. I would also guess a dry sump car would have it on the oil tank, but I didn't see it on the TAV.
