I have just replaced all the o-rings in the EAS Valve Block using a repair kit. While preparing for the "project" I did a search for pictorial how-to's and found one on the rr.net main site. They are both excellent guides and I credit them in my own guide that I have put together at
What I was trying to achieve with my guide is primarily a record for myself of how to put it all back together again, and it has turned in to a fairly lengthy pictorial that is specific to the P38A valve block from start to finish, or thereabouts.
To the moderators of this site...
If you find all or parts of the guide useful, feel free to take what you want for inclusion in your own guides or web pages. If you want to make this a sticky or host parts of the guide on the main rr.net site, I'm fine with that too.
Hope this is useful for other P38A owners.
