Oil Filter Assembly

Design description: The oil filter assembly in the Giulietta engine is a
full-flow design. Full-flow oil filters protect the engine superbly, because
they trap solid particles which could cause wear on the first pass through
the lubrication system of the motor. The oil filter assembly in the Giulietta
and all of the later cars (like the 101 and 105 Giulias) is located
downstream in the oil lubrication path of the engine after the oil pump,
and features a replaceable element contained in a canister attached to the
crankcase with an alloy mount. The whole system is very rugged and
reliable and rarely needs any maintenance attention. There were two main
suppliers of oil filter assemblies in the Giulietta era--FRAM from the USA
and FISPA (Fabbrica Italiana Specialita Parti Auto) from Italy.

Oil filter mount: As previously mentioned, the oil filter mount is cast in
lightweight alloy and is located just ahead of the exhaust-side motor
mount low down on the crankcase. The mount incorporates a bypass valve
into the head of the unit, which ensures that oil continues to flow to the
oil passages and various components of the engine should the filter
become clogged. Identifying an older oil filter assembly on a Giulietta-era
Alfa is sometimes complicated by the fact that there were two suppliers of
the item, and one of the suppliers (FISPA) seemed to follow no set
practice for part number identification of the units. In the '50s and '60s,
the FISPA logo was cast into the mount or attached as a small brass tag
to the same part.

In any event, cartridge-type oil filter designs became dated with the
advent of spin-on oil filters in the '60s. Because time has passed this
design by, many Giulietta oil filters have been adapted to the more
modern spin-on type, which offers the convenience of being able to get a
filter from just about anywhere at anytime in the USA. There are a number
of firms making spin-on oil filter adapter housings for the Giulietta engine,
with the Hurlock Engineering unit stocked by Portello Works being one of
the best--if this is a desired modification.

I happen to like the old cartridge oil filter design, and have gone out of my
way to keep a supply of filters ready for oil changes. One of the nice
things about the design is that during the oil change procedure, the
canister can be "prefilled" with oil, then bolted back in place easily. This
ensures that the engine bearings get a pressurized supply of oil within
seconds of restarting the motor, which is definitely a good thing. While I
have never modified any of the older Alfas with cartridge filters to the
spin-on type (except for racing), many enthusiasts have, and one system
seems just as good as the other. To each his own....

Oil filter canister: One of the myths about Giulietta oil filters is that all
750 series cars had bright orange FRAM canisters. Over the years I have
seen a number of early cars with both the orange FRAM canisters and the
dark gray FISPA canisters, including a very original 1954 Giulietta Sprint
stored in the basement of the factory museum in Arese--with the gray
FISPA unit installed. In addition, the old illustrated parts book dating from
1956 lists both FRAM and FISPA units for all Giuliettas. Even so, I'm not
ready to take on the burden of debunking the established mythology of
the "Giulietta oil canister color controversy."

But I would like to describe one of the many deviations from established
folklore I've found over the years: While on a recent trip to Italy, I found
an old, never used NOS Giulietta oil filter assembly at AFRA in Milano. The
unit was still in the original box, and had hand-written tags (in
pre-ballpoint pen ink) with the part numbers for the mount and canister
assembly still attached. On the back of each tag was the date of
production--"01/56." When the canister was opened up, even the original
old-style oil filter was still in place, ample vintage evidence that it was
manufactured in the '50s.

The big surprise was that it was a FISPA unit--featuring a dark gray
canister with yellow ink lettering, something which shouldn't exist,
according to modem myth. Go figure....

Returning to the details of the early oil filter canisters, the Giulietta FRAM
orange units had a black ink label overlay with the relevant part number
and the recommended service interval (every 4,000km) for the oil and filter
on them, and the FISPA dark gray units had a light yellow ink label overlay
with the same data.

As far as I can determine, neither early-type Giulietta overlay (FRAM or
FISPA) has been reproduced in sticker form as of this writing, although
Portello Works has recently made a good reproduction sticker for the 105
series oil filter housings, which could be used on a Giulietta in a
pinch--although it wouldn't be strictly "concours correct."

In addition, FRAM bright orange canister paint is available from
Kilimanjaro Designs. Kilimanjaro specializes in producing extremely
high-quality stickers, tags, rubber bits, small trim and mechanical items
for most Italian cars made during the '50s--with an emphasis on Ferrari
items. Because every Italian car manufacturer in the '50s and '60s bought
components from the same small core of suppliers, many of the
reproductions made by Kilimanjaro are appropriate for use in Alfas,
Maseratis, Lancias, Fiats and various "Etceterinis" of the same era.

So, what type oil filter assembly was used on Project Giulietta? Let's just
say that the engine now sports the NOS AFRA-sourced dark gray with
yellow ink FISPA oil filter mount and canister--at least until it can be
proved incorrect through carbon dating or some other reputable and
established scientific method, not rumor, hearsay or "urban legend."

Oil filter cartridge: Given the fact that the original canister-type oil filter
assembly was retained for Project Giulietta, finding filter cartridges for the
unit was a "no brainer." Alfa Ricambi keeps a large quantity of filters for
most Italian cars in stock at all times, and it had no problem supplying
units for the Spider's engine.

The last time a cartridge oil filter could be bought from Alfa in this
country, the part supplied was made by FIAAM in Italy. Domestic
replacements to the factory item used to be made by FRAM, Purolator and
a few other companies, but supplies dried up long ago. I suggest using
the UFI (Universal Filter Italiana) brand in Alfa inline four-cylinder motors
with cartridge-type filter elements, mainly because they are high quality
and readily available at specialty Alfa parts emporiums like Alfa Ricambi.

Oil Hose

Description: The engine oil pressure on a Giulietta Spider is read from a
mechanical gauge located in the center instrument of the dash directly
beneath the tachometer needle. The unit itself is sturdy and very reliable,
rarely failing in use, unlike some of the later 105 series Giulias with
"improved" electrical units.

Giulietta oil pressure gauge operation is simple: Pressurized oil is fed
directly to the unit from the oil passage on the exhaust side of the engine
by a "soft" (flexible) line about half of the way and the remainder of the
distance by a "hard" (steel) line that finishes the circuit to the back of the
gauge proper. Of course, the flexible line is subject to high temperatures
and NVH (Noise, Vibration and Harshness) in use, and splits and cracks
with age.

The original Giulietta oil pressure hose consisted of two different
designs--the 750 series type had a dark brown fabric-covered rubber hose
with a steel winding running in a spiral pattern along its length, and the
101 series type featured a simpler dark gray canvas fabric-covered rubber
hose without the winding.

In the past it was impossible to get authentically correct period-type oil
pressure hose for the 750 series Giuliettas, but that has changed recently.
Portello Works has sourced and stocks the correct type hose and ferrules
(hose ends). Because the hose is supplied in differing lengths without the
crankcase or hard line gauge connector ends, a small amount of detail
work is required to make the hose fully functional. All that is required is to
cut the old ends off the original hose, cut the new hose to the proper
length, put the new ferrules over either end, and push the old ends (which
are "barbed") into the new hose.

The result is a perfectly authentic replacement hose composed of superior
modern materials, far stronger than the original item, that will last much
longer as well. Needless to say, I happily used the Portello Works product
on the Project Giulietta engine.
