Re: Pushrod squirting oil

Why would anyone say to block off the fresh air outlet, if the air lever is pushed down & letting air pass through are you going to tell me it might make the engine overheat. Yes the warm air might get pulled by the fan but some cars have fixed vents in the heater boxes that blow hot air into the e...

Re: 102hp engine

Brad made some good points. Yes the 64 fan was magnesium that fit the "smaller" bearing and was a one year only fan. In 65 the top cover was revised for a bigger (more durable) bearing. The 65-69 fans that fit the larger bearing are common. Some folks with EM engines change the top cover to use the ...

Re: Pushrod squirting oil

Fact is most of the dropped seats are traced to the larger valve 140HP heads. The other engines with the smaller valves don't seem to be an issue until approaching 100K miles or if the engine is badly overheated due to a broken fan belt and the driver kept going. The #5 cylinder seat issue is usuall...

Re: 64 Monza Transmission issue

If you do decide to rebuild the differential into the correct case yourself - you'll need an inch pound wrench to set the pinion shaft bearing pre-load - it's critical!! You can find inch pound wrenches on-line, they are made to assembly high-end bicycles.

Re: 1963 Corvair 700 Sedan

An old car buddy always told me "A car that doesn't run isn't worth anything". That's simplistic, but his point was you just don't know what you'll find and how much it costs to fix. I'm out West were rust is not the issue it is in other parts of the country, but you still find cars that need so muc...

Re: First classic car, where to start?

Thanks for the reply and the information! I’m located in the San Francisco Bay Area. I'm south in L.A. CA. Three good clubs down here. Wish I was closer I'd like to see the car and give a hand. Seth Emerson sells some of the best spark plug wire sets for the Corvair and races Corvairs. He's in San ...

Re: First classic car, where to start?

What a great find. The days of finding a nice clean original Corvair are nearly over. The engine looks like it has air pollution controls on it. That was only done in Calif and a few counties back East in 1966. Not an issue and doesn't impact performance that much, but a standard (non pollution) dis...

Re: Any socket grounding tricks ?

The metal sockets are an improvement, but you still have a ground going through the housing that corrodes attached to the body panel by wire nuts that corrode - getting the idea. A wire soldered to the socket (and some sockets come with a ground wire attached) that is secured to the body gives the l...

Re: SBC up Front Conversion

The Corvair LM convertible body is a bit flimsy so you'll probably have to put a full frame under it like others have done.

Or just go buy a Camaro to fix up. It will be worth a lot more.

Re: Engine rebuild

A tip on a on the13/16 socket to be used for removing and torqueing the rocker arm studs. I modified a 6 point socket slightly to give better grip on these. The "nut" part of the stud is fairly thin and all sockets are a little rounded going into their grip surface. To increase the grip of the sock...

Re: 64 Monza Transmission issue

I was wondering if I got a new 64 differential case if the gears could be transferred from my old one or did the gears also change from 63-64? The bracket I was referring to was the one listed in the add earlier in the posts. Looks like an after market adapter to put a transverse spring on an earli...

Re: oil cooler seals

Thanks I looked and couldn't find the torque spec . Its amazing how beat up the old ones were. The video shows the use of perma gasket. Probably not a bad idea to things in place during re-assembly. Use only a LITTLE (if you must) to hold the seal in place. You don't want it to squeeze into the oil...

Re: Pushrod squirting oil

Well it turns out "more is good" isn't that good. There are several things that cause variation in oil flow up the pushrod. The lifters make a difference. Did you inspect your pushrods to make sure they were not plugged? Also GM made two different pushrods!! Bob Helt, who does a lot of Corvair resea...

Re: 64 Monza Transmission issue

Ron - You could dismantle the transmission, but assembly requires some knowledge for good results. A fellow in our Los Angeles, CA club has been rebuilding Corvair transmissions for decades. Just about every year changes were made, some major, some minor. Unlike the later 66-69 units the earlier tra...

Re: oil cooler seals

If I recall correctly the cooler has a limit it will compress the seals. So they do not compress more depending on the torque. The biggest issue is making sure the seals are installed correctly. If they get off center during assembly they WILL leak. Folks incorrectly try to tighten down the bolts mo...
