<VV> Exhaust Donuts

[hallgrenn at aol.com]

Bill,

As Consumers Report said decades ago when they did a test of a Corvair concerning rumors of CO contamination from the heater, all you had to do was leave your vent windows partially open and there was plenty of ventilation to avoid a CO buildup.  Not that I recommend driving with a leaky exhaust and damaged shrouding.

And I'll make sure to have a CO detector in the car when the heater's on just to 
make sure it's safe.

Hi all.  Well, I pulled the manifolds off the old 110 yesterday.  The donuts 
looks like they were the original, white flakey stuff that was probably 
asbestos, and pretty far gone, too.  THey disintegrated when I knocked them off 
the exhuast stacks (I sprayed them with soapy water first to avoid dust).

The manifolds were also pretty cruddy with some rust on the seats, but I cleaned 
them up with light sanding and a wire brush.  The seats came out pretty clean 
and the new donuts fit them nicely.

One stack (I think cylinder #6) had its flange and sleeve rusted somewhat (but 
still useable), but I put muffler sealer around it and installed all new 
graphite donuts on the manifolds, then bolted everything back. The other 5 
stacks look like they are in perfect shape.

I've never tried to pull one of those stacks out of the head, but I heard you 
have to remove a pushrod tube first.  Sounds like a bear of a job.  I'm not up 
to doing that at this time, but as long as the system doesn't leak I'll run the 
car for a few trips, re-torque the manifold nuts and bend the locks down, then 
reinstall the shrouds.

And I'll make sure to have a CO detector in the car when the heater's on just to 
make sure it's safe.

Thanks guys...Bill Hershkowitz  66 Monza Sport Sedan 110 PG A/C
