chris if u type in www.acdelco.com/indexjsp and scroll to the bottom you will see the words General motors rights reserved 2010.  I have been told this is exactly the same oil as the branded GM one from my local Vauxhall dealership.  Thats why sometimes my local Vaux dealer have ac delco on the shelf

Just a thought, when i removed the oil filler cap and looked in at the cam shaft on idle i could see oil trickling over the cam shafts but not gushing around is that correct?

What for? If your happy with it fine. "It's not my rather car" as they say in the trade.  ;)

I use the GM listed stuff as it's on trade club and costs £36 for 20litres. Everbody's happy. :y

Maybe its only a grade above that  ;D

But it does keep the condensation on the filler cap to a minimum as well. The mark up on oil is outrageous.

The same dexos2 mentioned earlier is about £60 for a 20 litter drum on tc. Same oil product at a BMW dealer is £180 retail !!!! Because it's BMW. But they only sell it to people with pink shirts with white collar and cuffs. You know the type.   ;D

think i will start with new plugs. i have just bought an oil pressure gauge to fit at the weekend.  It is rated from 1-7bar. Do you know what bar the oil pressure should be at idle and on acceleration??

http://en.wikipedia.org/wiki/Delco_Electronics

Quote
Delco Electronics Corporation was the automotive electronics design and manufacturing subsidiary of General Motors based in Kokomo, Indiana.

The name Delco came from the Dayton Engineering Laboratories Co., founded in Dayton, Ohio by Charles Kettering and Edward A. Deeds in 1909.[1] The "AC" often seen in front of the name are the initials of Albert Champion, a pioneer in the development of the spark plug. He made the change during his tenure at General Motors, after they took over Delco.

 :-X

I am trying to find the official oil pressure specs. Unofficially, I would say 3 bar plus at speed dropping to 1bar plus at idle(when hot). If low pressure is the issue I'd expect quite a racket as all the lifters would start complaining. Not sure that would fit the description of a "tick" but as you have the gauge, may as well rule it out.

update on ticking noise.  Took car to garage today and put on four poster. Mechanic checked exhaust system and after a bit of head scratching commented there might be a slight leak at passenger exhaust manifold.  Cant see any soot around it and to be honest i cant hear any blow out from that area. Po420 code and light appeared today after about 3 weeks of being off.  Does the 3.2 (2002) have an EGR??
I ask this as my neighbour works for my local vauxhall garage and he suggested the gaskets can fail on them causing a ticking/clicking noise.  If there is one where exactly is it and could this be the culprit

No EGR on 2.6/3.2. Read this about 0420

i my view the ticking noise is coming from the back of the engine and is most noticeable when i put my mechanics stethescope behind the plenum.  What exactly is behind and below the rubber pipework feeding into the plenum?.  Has anyone got any pics of the rear of a 3.2 engine?

Can't think of any other suggestions tbh. Unless it's in the head itself, there's no known issue that would cause a ticking in the area between bulkhead and engine.

Unless Kevins suggestion of pressure relief valve applies I can only assume there's something rattling around back there? Maybe from fitting the new engine.

No egr on the 3.2.

I suppose remove scuttle and run the engine? Unless it's lifter noise, which we have discounted, it will be an unusual cause I would think.

chris, whats the gold/brass coloured cylinder mounted horizontal behind the plenum?  Put stethescope on it and could hear quite a large ticking from it. Not sure if its the culprit but would like to rule it out.

That ain't standard, by the sound of it.

This is a 3.2 v6 omega engine right? Had it got LPG or something? Pre heater? What's it plumbed into? ...  :-?
