Corvair Forum

I've found that EM 145CI engines are more reliable. Fewer spun bearings and they don't seem to break pistons. The vast majority of miles I've put on Corvairs have been EMs. I love the LMs style and handling but they seem to not be made as well and tend to have more rust. EM Early Models 60-64, LM La...

All good stuff to check. Gas cap, fuel pressure, accelerator pump diaphragm. If fuel shot out gas cap is for sure wrong. Clark's sells the wrong one or at least used to. One other thing to check is the tang on the float needs to be parallel to the needle tip. If it isn't it will put a side load on t...

I need some competition.
I have a lead on 40 and I'm lacking motivation.

Max pressure on the sidewall is cold. Max pressure isn't that critical either since they can't even be bothered to define cold. Here in TX where you can have 20 degrees in the morning and then 80s in the afternoon will get that pressure way up there hot. My friend that ran a tire store since the 80s...

I've been a member forever but if they don't get rid of Vargas I'm out when it expires.

Looks great!

No turbo ever had factory A/C and '65 140s didn't either.

2LZ - where the politics hurt you is when they destroy a forum like happened recently with Corvair Center.

"GM had little experience with riveting flywheels" Isn't that the very definition of incompetent? "not having or showing the necessary skills to do something successfully." I never heard the engineers specified Viton. I have read the engineers were ignored on the Vega aluminum sp...

If you need to change the o-rings buy the tool Rex sells. Makes the job easy compared to almost impossible.

"The GM engineers know everything" is a bad argument. They didn't. If they did they would have used hot rivets in the flywheel and Viton push rod tube o-rings. Viton was available. A lot of things were done because it was cheap or because they could get away with it when warranties were 1 ...

I hadn't thought about it much but I would think being bolted to something that runs 250 degrees or more would cause it to run hotter than being bolted to something that stays at ambient temperature. I'm not sure it matters. I've never had an oil filled GM coil fail. I have had a lot of the newer ep...

Newer forged pistons use tighter clearances.

Excellent document. Thanks!

It said 100 at full lean and 130 at full rich.

You get 90% good advice here and about 95% bad on Facebook. I feel sorry for the newbies there. I don't see how they can sort through it.
