What have you done to your Ferrari Today?

TIL my 308 has a battery cut off installed. Hidden down between the pedals. Never noticed it before, thanks PO!

 

First post, congrats! Got pics of your car?

 

I got the car back from a checkup on Monday. Working great. No issues..

Then I Image Unavailable, Please Login got out for couple drives this week with my sons.
Our regular route to Jägersee.

Yelling at it, it was standing in my way...

Nice Azuro! Thanks for posting!

 

Had a head-on collision with a large poorly-marked speed bump today. Can't see any damage, mercifully.

Was out on a grocery run. Safeway is 2 miles away; somehow incurred 32 miles on odometer. Funny how that happens.

 

My right cooling fan has been making some "old dying fan" noises, and the left one doesn't keep temps down as much as I'd like.

So have replaced those 40-year-old designs with a couple of modern high performance Spal 10" units. Can't wait to get the car back together tomorrow and try them out.

Thanks!

 

Spent all day yesterday working on my GT4 with my son. We took the engine out a couple of years ago and replaced the sodium exhaust valves and did a complete heads rebuild, valve job, etc. Got the engine back in last year, but health problems have been slowing down completing the job. We got the dipstick and tube installed, alternator installed and wired, along with the starter. Had to replace some wires and connectors. Then we got all the cooling system hoses replaced from the radiator back to the engine.with Gates Green Stripe and all new SS clamps. I had done that job 30 years ago with the car up on jack stands. Having a lift makes it much easier. The Gates hoses I used back then looked like new, but we replaced them anyway.

I've got some cooling system connections to make in the engine bay, then it will be ready for vacuum testing. Cross your fingers.

 

Nice alloy radiator! Let us know how they work.

 

Last Friday - got the car back with these installed... custom s/s, mandrel bent headers

Learned a couple of things about my Throttle Position Switch. Firstly that by using the throttle position screw to increase the idle it caused the microswitch in the TPS to disengage in idle position. Secondly when the TPS was in wide open position the second contact switch inside the TPS was no longer operable. I bought a new one on Amazon for $64 delivered vs $200+ from one of the other parts sources.

I discovered the problem with the switch when I disconnected it to replace the AMP connector with a new one. I noticed that the mounting tabs on the TPS were elongated which to my shrinking brain indicated the position was adjustable. The adjustability has to do with making sure the leaf switch inside the TPS is in a closed circuit state when the car is at idle. This is how I understand this switch works:

The TPS has 3 conditions it tells the ECU about:

1. Idle - when the idle switch closes it lets the ECU know it's at idle and the ECU in turn sets the Freq Valve to a given freq for idle.
2. PT - neither switch is closed (Not at idle and not at WOT) again it has special freq valve control for PT
3. WOT - the WOT switch is closed but idle switch is open, here it sets the freq valve so it lowers control pressure. It opens the frq valve a bit more to lower CP, this instantly causes a richer mixture.

I've read many posts about guys having problems when there car comes to a stop at an intersection, etc. Maybe a failed or unengaged, or misaligned TPS is the problem for some of them.

Nice weather in Scotland just now, so driving it. Slowly building up confidence, done 170 miles now since I got her going. Had been sat in a lockup for 14 yrs, left there by the previous owner. Really starting to have fun, then the starter motor failed yesterday!!

 

14 years! Hoping the starter is all that gives you grief.

 

Thanks!

So what are the contacts in the TPS? That is, which one is for the idle switch and which for the WOT? I'm guessing that one is ground .

 

Driven to work all week ☀️

 

Check this out. Great video explanation.

 

Did my annual fluid changes today: engine oil, transaxle oil, coolant, brake fluid.

Been losing an abnormal amount of coolant out the overflow tube lately. kcabpilot's posts have inflamed my paranoia that it is a blown head gasket. It is probably just a bad coolant tank cap. Just ordered a Stant 10231. It will be here on Sunday.

Putting 100 miles on the car tomorrow, picking up Black Horse and driving to Berkeley for an FCA Technical Session at Patrick Ottis. Will see kcabpilot there too. I love events like this.

 

Jealous here! Good travels...

 

You've read my thread and talked to me Brian, it's a long road to determining a head gasket failure and along the way there are a hundred other things that can be the cause of the same symptoms. Since you just renewed your coolant I think you just need to bleed a bit more. If you don't see a constant stream of air bubbles coming into the tank like I did you're good, just keep bleeding the trapped air out of the radiator after each drive for awhile and it should resolve itself. My own personal head gasket issue is just karma because deep down inside I was looking for an excuse to tear my engine apart anyway just to see how it works

 

My new Stant 10231 coolant tank cap arrived from Amazon yesterday ($4.17). I overfilled the tank, put on the new cap and took the car for a 30 minute drive at low speed. I stopped and let the car idle to let the engine heat to the point where the radiator fans came on. This morning, now that the engine is cool again, the coolant level is back to where it always used to be (in my car's case, 5 cm above the bottom of the expansion tank). Harmony in my universe has been restored.

I am very fortunate in that my car bleeds easily. I have drained my coolant 5 times now. For my car, I just need to open the bleed ports on the radiator and thermostat and fill until coolant starts spilling from the bleed ports. Through the year, I bleed the little bit of air out of the radiator occasionally, but it is really unnecessary.

 

Just fixed my air vent today.
Its really hard to find a new one.
Next thing is fixing the o ring from the gearshift and new fuel accumulator.
Hope next week parts are at my place .
