Major on my 308QV

Ok, I decided to move this thread over as Tom Jones from Sport Auto begins a full major on my 308QV so more people would see the thread.

Here are a few pics he sent today that brought two things to mind:
1) Thank God the car is in his hands now, as waiting any longer may have been tragic
2) The car is in the right guys' hands

Figured I should show you some of the "before" pics so you will realize how good it will be when he is done with it!

Looks like you've caught it in time!

That's a fairly clever repair to the air injection manifold pipe -- but having a rubber hose component on the manifold side of the check valve isn't so good. I'd bet that the prior check valve failed originally so overcooked the pipe even more quickly than normal -- unfortunately, due to US emission laws, no auto manufacturer ever want to admit up front that an emission component needs to be replaced before 50,000 miles (IIRC), but not replacing the air check valves at every ~30K miles is crazy IMO.

 

Interesting comment, Steve. With all the chatter on here about doing majors, that is one component that is rarely, if ever, mentioned as part of a routine "major" service. Everyone concentrates on the belts and pulleys and bearings and seals and timing, etc. But no one talks about actually changing the air check valves as part of a service. Rather, it seems to be one of those parts that everyone lets go until it actually fails.

Thanks for the heads-up on that.

 

Yes, I wouldn't buy them from a F part supplier , but, since they are GM, they are dirt cheap from a US domestic auto parts store. On the later US (1984 and after) "pulse" air injection models, letting an air check valve fail can get pricey because the just-upstream (plastic) cut-off valve can be melted way before any other external symptom is noted.

 

is there a PN for the GM ones Steve?

could this be it?

Ditto. How about for the 328s? If there are readily available parts we can use from our local auto parts store, that would be very helpful and cost effective.

Thanks in advance for the info!!

 

In the parts thread, I have the number for my '83 & a thread somewhere with pics.
It's pretty easy just to go to your local parts place (even pep boys & autozone when they aren't busy) and match them.

 

That's very close, and would probably work just fine, but the diameter of the nipple where the rubber hose attaches might be a little small vs the stock F ones. There is a whole network of aftermarket vendors who make this stuff (besides GM) so taking an old one and matching it up is a good way to go (if you can't find more exact details in the parts cross-reference thread = your homework, not mine ).

 

Tom will be installing this fuel hose kit - purchased from Daniel at Ricambi (Thanks to Dave Helms at Scuderia Rampante for developing these):

I have the same fuel hose kit on my '83 QV as well. Before installing, the fuel was drained completely from both tanks - which removed 30 years of possible sediment lying on the bottom of the tanks. The nice thing about Dave Helms's fuel lines is that they can withstand the ethanol added to most fuels these days. The original rubber fuel lines are not made to withstand harsh ethanol fuel additive.

The project looks great, Matt!

 

I still need to refresh these on my car and haven't even looked yet at what is under there (well, I know the pup hoses connecting the two tanks look like they need to be done). Where do these four hoses go? 119281 is particularly weird looking.

 

114277 - cross over pipe (2)
117618 - filler tube
119281 - tank to fuel pump

 

These are 'bare minimum', as these hoses are under constant saturation. However, I'd also replace the two lines that mate the top crossover tube to the tops of the fuel tanks, as well as the rubber 'return' ines from the Fuel Dizzy to the passenger fuel tank, as well as the rebreather lines to both tanks.

 

+1 I recently replaced all of those. On the driver side tank those 2 green breather hoses can actually have fuel in them sometimes. I jacked up the pass side of the car recently and actually saw fuel in the rear line. With a full tank, fuel will move over to the drivers tank and actually raise up. If fuel were to leak there it would flow down behind the tank and possibly on to the exhaust. It's no joke. Those should be replaced with all the other fuel lines. Also make sure to get the green fuel hose for that application.

 

Noted, and will defer to Tom on if we need to do those - I already had the return line replaced by Radcliffe Motor Cars about six months ago.
Also new water pump on the way to Tom right now...

For those of you who don't frequent the NC Thread, I am also replacing the diaper in the back and adding these new Hedman tips. Keeping her without CATS and Magnaflow silencer. Sounds fantastic.

Wow. Good warning. Do you have Ferrari / Ricambi part numbers for those?

 

Tom said he had all the other fuel lines in hand that I haven't given him so the other ones I haven't had done he will replace.

Those Hedman tips are look proper

 

An OEM Rear "wing" being added to replace Fiberglass one. Have an OEM Targa top too purchased from another Fchatter but need to have the fabric replaced on the inside since it is the doesn't match my interior, I have the material in hand, but interior refurb comes after Major and suspension work.

Tom is going to rebuild the steering rack and put in new bushings as well.

You do all realize that when I get done with this car you have no chance of buying it from me....ever

 

That happened to mine the day I bought it.
