Al:
Is your crankcase breather hooked up and working? If not, get it
hooked up. This would explain the oil getting pushed out of your pan
gasket; the crankcase is pressurized and that pressure has to go
somewhere.
Are you using an external oil line to get extra oil to the valve
train? If so, remove it. This is often the source of excess oil
consumption. If your oil leak is large enough, it could account for the
consumption and the lack of smoke - the oil is being left all over the
road when you drive the car instead of being burned.
What color are your plugs? Are they sooty black, grayish/brown,
or white? This will tell you if you car is running rich or not.
As for the compression readings, they are high for stock, but
fine for a 9-9.5:1 modified motor. Look elsewhere for the source of your
oil loss.

Subject: Re: [6pack] compression
I've been having a problem for awhile in that the car has been using a
quart
of oil with every other tank of gas.
I did a compression check and the readings were 145-140-130-130-130-145.
I just noticed that the spin on oil filter was a bit small and changed
that
to the correct size.
Oil was being pushed out the oil pan gasket, even after changing the
gasket.
The car only smokes when when I gear down and accelerate; and part of
that
may be beacause its running too rich.
For the amount of oil its using, I would think it would smoke quite a
bit
more.
How bad are these compression readings?
Thanks
Al
