Shop Manuals, Assembly Manuals, Clark's Catalog – Everyone Needs These!

We highly suggest the shop manual & Assembly Manual (see pages 243B & 244).

Clark's Catalog – Offers info & answers to 100's of everyday questions.

GENERAL ENGINE INFO: OIL – All stock engines take 4 1/2 quarts of oil. 10W-30, 10W-40 or even 20W-50 (in hot climates) are all ﬁne high

detergent oils (HD). FUEL – Car gas tanks hold 14 gallons; FC tanks hold 17 gallons (16 1/2 gallons – tank with hole). 92 octane fuel must be used

(unleaded is ﬁne & no lead additives are needed).

"TURBO AIR" – All Corvair engines are referred to as "Turbo Air". This term does not mean that they have a turbo. Turbo engines have a turbo

charger (original turbo engines from 62-64 were 150 hp & 65-66 were 180 hp).

140 HP ENGINE – 1960 motors were 140 cubic inches; not to be confused with 65-69 140 horsepower engines. The 140 hp engines have 4

carburetors.

ENGINE REBUILD HELP – Our engine kit questionnaire is available on our website homepage (www.corvair.com). For the most accurate engine

rebuild quote, ﬁll out this form. The cost can vary on an engine rebuild greatly depending on the parts used.

ENGINE BREAK-IN OIL – For years, break-in oil was suggested. Most claim it is not necessary, however, we suggest quality non detergent 10W-30

oil for the ﬁrst 500-1000 miles w/ ZDDP additive (C379X). Drive 40-60 mph during this period, varying your speed but not "pushing" the engine. Change

oil & ﬁlter at 500-1000 miles and switch to 10W-40 or 20W-50 plus ZDDP additive.

CAMSHAFT BREAK-IN – To insure long camshaft and lifter life, please follow these steps. 1. Lube the new cam with cam lube supplied with

new cam. 2. Only use new lifters and apply a thin layer of cam lube. 3. Add ZDDP to your break in oil & with each oil change. 4. Adjust lifters

accurately (see page 394).

INSTALLING ENGINE SEALS CORRECTLY

1. Remove old seals and clean area. 2. Apply a light coat of lubriplate or

oil on outer ribbed surface to aid installation. From the Shop Manual – Coat

seal with a high melting point grease between the sealing lips on the inside

diameter. Seals to be installed must have this grease, which is retained for

the life of the seal (any quality all purpose chassis grease will do.) 3. Be

sure seal area is smooth & coat with oil. 4. Seal area can be polished with

600-800 grit sandpaper.

Valves – We know there are cheaper valves, but doesn't your rebuild deserve the best valves you can buy?

● Our valves can survive without lead.

● Our intakes are superior to regular intakes & the exhaust valves are made from high quality stainless steel.

● Exact manufacturing. Valves are specially made for Clark's; not mass produced. They are made on high tech CNC machinery, which uses

a special laser to monitor precision grinding of the face angle.

● Our valves are tufftrided which gives a wear, scuff & seizure resistant surface along with improved oil retention. This gives our valves the

black appearance.

● Individually wrapped so they get to you in perfect condition.

TRANSMISSION & DIFFERENTIAL – Differential oil is 80-90 gear oil & is shared w/ std trans oil for a total of about 7 pints.

GASKETS – The original gaskets between the transmission and differential were 1/64". For some reason, over the years, this thickness is not sealing as

well. We believe the problem may be distortion of the surfaces and bolting areas. We have therefore changed all of these gaskets to 1/32".

POWERGLIDE – The powerglide transmission uses Dextron II transmission ﬂuid; 6 pints for a reﬁll or 13 pints if the torque converter was also drained.

CLUTCH PILOT BUSHING – Be sure to install fully into the hole.

TIRES & SUSPENSION

INSTALLING BALL JOINTS – Do not grease until they are installed! If you grease them before installing, you risk "blowing out" the rubber seal.

Old Tires? – Don't take chances on the road with old tires.

Tire manufacturers don't suggest using tires after they are 6 years old. Some people think that it is OK for up to 9 years if they are

stored inside, but the rubber does start to age & the threads can come off or you could have complete tire failure. I had the tread

come completely off on a 12 year old Michelin that looked brand new that was on the front of my 66 Corsa. How do you know the

age? Check for the "DOT" on the side wall. If the last digits consist of 4 numbers, it was made since 2000 (example: 1101 means the

11th week of 2001; 0100 means the 1st week of 2000). Check the internet for up-to-date tire code info.

STANDARD TIRE SIZE – P185/80R13 is the standard size tire for all cars; these are becoming difﬁcult to ﬁnd.

CHEAPER LOCALLY? Are they CORRECT for CORVAIR? Are they GOOD?

Our pressure plates all get new diaphragms (most places just clean the old ones). Our brake shoes are premium asbestos-free linings on the correct

steel backings. These are just a couple of examples of why ordering from Clark's makes sense; we know Corvair parts. You might ﬁnd local ones that are

cheaper, but are they 20 years old? Are they exact for your Corvair? Is a slight price difference worth your time & aggravation if it isn't right?

REPLACING A STOCK OIL PUMP?

We suggest that you also order C1009E which

includes .003, .005, .008 & .010 gaskets plus a

piece of plastigage so you can determine which

gasket will give you the 0.002-0.004 clearance

needed.
