Question Spica Micro Switch oil leak

Dear all

My Alfa Romeo GTV from 1974, spica injection pump is leaking oil, apparently by the micro switch. This fault, apparently, was reported and repaired like 10 years ago (only 3.000 miles the car has runned since then).

What do I need to do? Remove the whole pump? I'm asking for some spare parts to centerline and it will be very helpful to know which spares I need to order.

From Uruguay

Thanks in advance


Gonzalo

Question

Sorry! This is my GTV, from 1974 one owner 69.000 miles. I'm waiting for new door mirrors !! These are Baby Tornados, changed in the USA in 2003.

The rest of the car is absolutely original. At some point it was resprayed something that in next February I will do the same because when It was parked it receives a hailstorm.

Yes, you need to remove the injection pump to replace the microswitch seal. The easiest way is to remove the pump body from it's base (six nuts). Unfortunately, as far as I know, that "hat seal" is no longer available, and I do not think Centerline has them. You should contact Wes Ingram (he rebuilds Spica pumps). Maybe he has some replacements.

Below are some pictures of that seal:

Dear John

Thanks for your prompt answer.

Life will not be easy with this pump!! Today I ordered all the spare parts available at Centerline in order to remove the pump and change all of them. Due to the fact that the car was not running I think that it has all these leaks.

Regards from Uruguay

There is documentation somewhere of a guy changing this seal without removing the pump. I sure wouldn't want to try.
A friend just had this issue, and the microswitch was broken in any case, so he just gooped RTV sealer in there, seemed to solve the leak. Not ideal though not to have a working switch.
If you're experienced, it is not that time-consuming to get the pump out. It is a number of steps though. And whichever way you remove it, you should have the relevant gaskets on hand to go back together.

Before you spend a lot of money on just replacing parts on the pump, do a bench check to assess it's serviceability. Many of these old pumps are "leakers" meaning they leak gasoline into the engine oil and must be overhauled. Download the guides in the FI/Carb topic area.

Rather than spend a lot of money overhauling the injection pump and paying shipping to South America, you might want to consider a conversion to carburetors. If the expense isn't a factor, then fixing the Spica system is fine, considering that once in good shape, it is very reliable.
