My belt doesn't seem all that loose but the groove does feel pretty smooth to the touch now that you mention it. That's not something I even considered. Is there a way to roughen that up? Sanding it or something? And is that even wise?

Okay got it.

As for removing the top shroud, everybody on this forum and the other blue forum talks about it like it's just changing the oil but in my mind that's a really big deal. If I did that myself I'm pretty sure my car would never run again. I know my limits I just can't do that. Yes I have a shop manual yes I've read it. Seriously it's a cliff I can't jump over.

What does your head temp gauge indicate when it is that hot?

How do you know the oil is boiling??

My head temp gauge doesn't seem to be working. Whether it's the gauge only or if it's the thermostat itself, that is an issue I'm prepared to tackle and I'm currently investigating it.

I know the oil was boiling because I went around the back that first time the car died in the heat after driving it for 40 minutes and opened the hood and literally heard a boiling sound.

As I said I'm lucky that only happened to me once. And I have since tuned the engine and installed a lot of newer parts. But it still gets hot in ways that make me uncomfortable. I have no idea if that old issue is making me paranoid or if I have a real problem.

Someone here mentioned that they had a laser temperature gauge? Where would I get one of those?

It's an optical/infared thermometer, handheld. Harbor Freight, Fluke, Omega.

The "laser" is the red LED that points to the object to test.

Long before oil reaches a boiling point the engine would be so hot it would shut down. Loss of power is noticed at approx. 435 degrees head temp. You need the gauges in the instrument panel to work so you can monitor the engine.

It isn't 'thermostat' but the correct word is 'thermister'; the sender for the head temp gauge.

Layton!! Baffle tins are on the BOTTOM of the cylinder barrels...but DaveMoto showed us one with them on top!

And our engines [ low hp ] will not overheat when missing the Baffles..

Wife bought a '64 Monza vert 110 /pg.... rebuilt engine... no baffles.... driven several times per year from Sacramento, over Donner Pass to Reno... then Vegas, then San Diego, then back to Sac.... Puked oil! But is still running fine today.... yes I installed baffles when doing the O-rings..

peepee, The Boiling oil is PUDDLES of oil boiling... have you washed the engine yet?

And why you bought that 4-7 psi pump when we constantly say, and it's in our FAQ's
1-4psi ... Turbo's / YH's like 2.5-3 psi.... Rochesters 3-5 will normally work..

Eric may thoughts are that you need a good Corvair guy to help you. If at some point junk got pulled into the fan it just lodges on top of the cylinder and head cooling fins effectively preventing the air from cooling the engine so it will overheat easily and worse unevenly. I understand your hesitation, I'm an electrician but I've taken both mine off successfully. If you tackle it take lots of photos and mark things well, do not remove the distributor, or move it. Most other things really are not hard or too difficult and just need to be put back how they were, photos. Good luck with it.

You must remember this is a Turbo!

Even I keep greasing the fan bearing rather than tackle that nightmare!

If you just bought it and it's overheating I would have to see what's under there. How about a borescope, poke it in there and see if there's stuff.

At least remove the oil cooler cover and inspect!! Under the ALT.


And wash that warm engine with a 5 gallon bucket of Hot water and a strong detergent TIDE! TSP

Do it someplace where the mess is not a problem ggg

I have put many hours on my Spyder in 80-90 deg heat and no problems at all with engine temp. You have an issue for sure if it truly is overheating, they do run hot. Normal as indicated on my gauge on the highway is 400 degrees at 70 miles an hour and that does not seem to matter what the outside temp is.

I did not compose this but I'd thought some readers might find it interesting...

So, just if anyone asks, what happens to a vair motor when you over heat it.
When the belt comes off, you have about 4 minutes of time before it really starts to get hot. Loose a belt on an auto cross course, you will be fine as most times that course is only 2 min long.
Here is what happens.
Any items that has a press fit.
Valve seats
Valve guides
Cam gear
Distributor drive gear
Oil pump shaft
Piston pin to rod
Fan bearing
That press fit is no longer
Items that are heat treated for wear.
Cam shaft
Lifter
Fuel pump cam
Crank gear seal surfaces are now soft
Items that are now out of round
Cylinders
Pistons
The head studs, are spring steel, they no longer has the pull force to keep the heads torque down.
The piston rings have lost the spring effect to keep the compression up, as also the cylinders are no longer round.
Every bearing is no longer in spec.
Every seal and gasket if more than likely melted along with the spark plug boots, spark plugs were heated past there heat range, the threads are way too soft to hold them.
If the motor still had cast pistons in it, the steel struts cast in have started to crack the area below the oil control ring.
If it has forged pistons, usually the pistons expand soo much that it will lock a piston into a cylinder and cause the engine to throw a rod.
Most think that once it cools off that, the motor will be fine. It becomes a ticking time bomb. There are no parts to reuse on that motor after that happens. Its a throw away.
So when you hear that someone has totally overheated a vair motor, you now know what it really does. Its not pretty.

So true!! Why we find MOST engines have not really been overheated...


Most panic when they see smoke [ oil burning off the outside of the engine ]

Never had to ever replace piston rings on a "reportedly" overheated engine..

I find the first thing that happens...and makes the engine run lousy.....

Balance tube connector hoses melt causing the engine to run terribly....bought a few of these...back on Craigslist the next day!

This is all very good information and is making me feel much better about my situation. Maybe I am just a Nervous Nelly but I'd rather be that than somebody experiencing that list above.

This is only my second Turbo and the first one was when I was 16 and it was technically my dad's. In other words I don't remember a thing about taking care of it. So if it's supposed to run hotter than my others then great but my basis for comparison is my last car, a 110 Powerglide that ran like a top.

I really like the scope idea. I'll figure this out. I have the combined brain power of every Corvair owner in the United States at my fingertips.

Thanks all!

Oh and Matt--
I've already removed and cleaned out the oil cooler. It really needed it. That was my whole adventure with the hard-to-reach bolt, remember? Also, I heard you about the 7 PSI pump. I just ignored you. I prefer combining a higher pressure pump with a regulator. smiling smiley

If the cooler was really plugged... bet there's more... but get the IR gun and read your oil pan skin temp when you think its hot and let us know what temp you find.

They were on sale the other day for $9.99

ebay have it in 3 days from SoCal! $9.84
