Just wondering what normal tick over vacuum to expect on a V6.
Got a vac gauge connected to the feed to the sai solenoid valve and its reading a steady 19 inches of mercury at tick over, is that about normal?
-
Yup 19 is good, 20 is excellent.
Check it at a steady 4000rpm as well.

Cheers Mark, expect a few of these type of questions as Mr Massive and myself have aquired these new toys.

Fantastic bit of kit, one of the single most useful bits of engine diag kit there is!
And unfortunately, they are little used these days....
-
Remembered you saying they were useful.
What should I expect at 4K, zero vac as I rev then building back to 20+?

....even I`ve got one! :y
Albeit a simple Gunson`s combined vac/fuel-pressure gauge.....`used it for car and aircraft engine fault finding over the years.....it`s quite old: do they still make `em?

On constant revs under little load, the vac should remain close to 19-20.....only dropping to zero at full throttle.
As for fuel pressure measurements, not recommended on fuel injected cars with 3 Bar plus fuel systems, fine on carbs in general though.

Gunson's "lo-gauge", I think?
I bought one from Halfrauds a few years ago so I assume so. :y

Down to your Massive negotiating skills mate. ;D ;D

Shouldn't this go on the OOF map ?, I mean we have the Tech 2's there, we obviously need a location for the vac gauges, and I got a pressure bleeding kit, so that should go on as well ?. Plus TC cards, plus who's got decent torque wrenches etc.
Servicing could be very expensive if you have to travel all over the country to access tools. Down to Notts for a quick Tech 2, oh dear mixture not quite right, up to Massive country for a Vac check, sounds like a gasket gone, down to Brum to use a trade card to get a gasket set, down to Wales to get some help from James V6, and back up to sunny Gomersal to change the brake fluid. Would be cheaper booking it into a VX agent ! .
