[urq] Head Gasket Time??

[W.Stedman]

Sorry for the long post but I do not drive my car much and changed the head
gasket and did a valve job about 4 years ago.

But the past few weeks I have been doing construction in the garage so I
would start up the car and pull it out into the driveway just about
everyday.

And when I pull it back in the garage I have noticeable amount of water
dripping down on the ground from the catalectic converter fitting.

So I checked the oil cap and there was a little bit of light brown stuff
kinda like when you blow a head gasket I then marked the water fill tank
with a pen and drove for about 50 miles pulled the car back in and let it
sit for a few days then checked the mark and the water level mark did not
move and there was no sign of any of that light brown film under the cap?

There is no oil floating in the water either?

The oil even looks clean?

Could this just be some kind of condensation from starting the car all the
time and only running it for a few minuets max?
