I have just received the "Geoff Walsh" cylider head for my 3B, and I have a couple of questions before I install.
He head came with a list of hints and suggestion regarding proper fitting. These instructions seem quite straight forward except for the following:
1. The list of hints states that it is a good idea to coat the head gasket with copper coat or a similar product. What is "copper coat"?
2. Also, I quote ... "all the air must be bled from out of the water system, with heater left on open circuit, air risers on cylider head, "bleed!"".
I'm not sure what they mean here. I don't recognize the terminology "air risers". Nothing is mentioned in my manual about this. What is the best method to bleed the water system, and what exactly are the air risers?
Any other advise regarding this installation would be appreciated.
Thanks
