Maybe I'm all wet but what test would help you to isolate the #1 hole valve guides by tapping a fitting into the balance tube? If I suspect that I have a valve guide problem, a good wiggle test will usually show it with out having to pull the head. Any reason not to suspect that you might have a broken or frozen ring? Bill -----Original Message----- From: triumphs-bounces@autox.team.net [mailto:triumphs-bounces@autox.team.net] On Behalf Of Allen Hess Sent: Friday, July 06, 2012 2:10 PM To: "triumphs list" Subject: [TR] TR4 vacuum port I've had occasional but persistent oil fouling of the #1 plug for a few years and a hotter plug in that cylinder has helped. Symptoms point to worn valve guides. I was going to get a vacuum gauge and try to do some more diagnosis. However, I don't have any manifold vacuum port other than the advance line in the carburetor. And I'm not sure that would work as it lies beneath the throttle plate. The intake manifold has two bosses cast into the balance tube which certainly looks like Triumph was thinking about this but it would have to be drilled and tapped. Anyone else been down this road?
