Sorry to resurrect a thread that I am sure has been discussed a zillion
times.

It looks like I have a leaking head - a small one at the moment.
What is the accepted wisdom of:

1.) If a head is leaking so that you are limited to a few hours driving
before you get the flashing red light - how long can I go before things get
really bad?

2.) Is it recommended to replace both heads?

3.) New or rebuild heads?

4.) Can you do this with the engine in the Van, or is it worth the trouble
to pull the engine?

5.) If you are mechanically competent, is this worth doing yourself? Or are
you better off taking this to a reliable shop?

Thanks.
