Ok got a little more time to explain a bit more about the noise/problem.
After the car was sitting for a week or more unstarted, when firing it up there would be a ticking noise present in relation to the revs. Ticking gets faster as the engine revs more.
After letting it idle for a minute, the ticking would go away.
Now and again when driving the ticking would be present but louder as the revs where higher. After a short drive or pulling over, the ticking would go away agian.
Done an oil change with CLASSIC motor oil, 20w/50 (duckhams me thinks as it was green) as stated in the book of lies.
Ticking and engine sounded good, but last night the ticking returned and lingered longer than ever before.
I haven't been out today due to time.
