Re: 140 Motor Progress

Alan - Glad things are moving along. A caution on the cold valve adjustment. This procedure is a bit tricky. The Corvair and SBC engines use individual rockers on balls. It makes finding zero lash difficult. If the lifter is dry only the lifter spring pushes on the pushrod with reduced tension. So f...

Re: Please ID this part, #2

The Corsa wiring harnesses for the engine, tunnel, fusebox (under dash) are different versus the Monza (and of course the instrument cluster has it's own wiring harness). You do have to add a wire for the thermistor to temp gauge, coil to tachometer, and the Corsa used two wires, one each for the oi...

Re: Wanted 1964 Stock Springs or Trade for cut Springs

You didn't specify front, rear, or all. The 64 rear coils springs are unique to the EM cars. When new the Corvair tended to be slightly high in the front. Most tend to keep the used front coils and install new rear coils to give a balanced look. Others leave the old rear coils in and cut just the fr...

Re: new from east los

Welcome - You own a "Caveman" car. This nickname started some time back because after the 1960 model, the 1961 the Corvair had a significant number of changes. So the 1960 car is considered somewhat unique and has a loyal following for being different from other Corvairs. It should be noted that the...

Re: 140 High Volumn oil pump

High Volume oil pump topic comes up every so often. Not recommended for a daily driver with good bearings. The stock pump in proper condition (and with the correct plate spacing per gasket) is more than adequate. Any excess pressure above the oil pressure regulator setting causes flow to be routed b...

Re: Positraction Plates Source

Brad - Your pic. looks like the later Posi unit, which had a more robust end cover. AZscott - even a worn posi will turn both wheels in the same direction. Typically it takes 50ft.lbs to slip one wheel vs. the other on a "GOOD" posi., but even worn there will be some resistance. If you turn one whee...

Re: Harmonic balancer / how to check if it's slipped

Agree with TT - The harmonic balancer (actually a damper) is a perishable item. As the rubber ages the unit no longer does it job TO PROTECT THE CRANKSHAFT. Once the outer member starts to slip it's only a matter of time before it comes apart. There are a few rebuilders around and Clark's sells new ...

Re: Carter YH carburetor

The YH had a few revisions and it takes someone with experience to sort one out, which is not me.

Bob Helt has published some well regarded Corvair books and he has one for the YH - Clark's sells it - http://www.corvair.com/user-cgi/search.cgi?part=C12813

Re: Turbo---180 hp vs. 150 hp

Actually the 64 Turbo was more than 150HP due to the larger engine size. In 65 other changes were made to bring it up to 180HP, including a revised turbo. One issue to note is the head gasket area was increased on the 65 and up engines. HP figures are misleading as they don't equate to driveability ...

Re: Opinion - Which is worse ?

Widman's paper is good. One thing he discusses is not only the corrosion problem with GL-5 (buffered can alleviate the issue), but he noticed GL-5 tends to increase wear of the yellow metal components even when it's buffered to prevent corrosion. There is no shortage of claims and ideas about Corvai...

Re: Hello from NC

I have not heard about the later models having thinner sheet metal. I'm still looking to buy, but the '64 and earlier are not as stylish, as the '65 and up, IMO. Body sheet metal gauge is hard to pin down. Body strength is determined by alloy strength vs. thickness. HOWEVER, the general consensus i...

Re: 140 Motor Progress

The "spark plug thingy" is a thermistor with a temperature coefficient that (as far as anybody knows) was used ONLY with the Corvair temperature gauge (Delco also sold them for use in small aircraft). Most new gauges use a thermocouple design, BUT you have to make sure the gauge has "cold junction c...

Re: 61 Rampside speedo

This was discussed on the other forum. --- Consensus is some PG FC's vehicles had speedometers with shift points.

Yes it's not unusual to see a car speedometer in an FC - they all have the same drive ratio. The gear in the transmission was selected at the factory to match the axle ratio.

Re: Aftermarket brake drums & shoes ?

The Chevelle brakes were used on the LM Corvair, but larger front Chevelle went on BACK of Corvair. Rear smaller Chevelle brakes went on the Corvair FRONT. One issue - The Corvair rear brake shoes require slots for the emergency brake parts. Now most vendors sell the same shoes for Chevelle/Corvair ...
