I did as much research as I could to find what oil would be best for the terminator. Amsoil 0w30 ftw.
Timing chain tensioner or a worn valve guide.
Try the Castrol 0w30 (the German made stuff). I'd guess it would be available outside the US as well. Used it in my S60R and it is good stuff.

That settles it then!
Or you can just get the Motorcraft EC743 cap - just says "Engine Oil" - that will ease your conscience...
nice noise...last time my car made a noise like that,,valve hit piston,cam follower fell off....2000 to fix...the cheap way
good luck
John Mihovetz(owner of accufab) did a big study on the " what oil to use" theory but I cant find it on the web as we speak to back up it up.
He found that the tolerances in the lash adjusters is the reason for 5w20 oil in the 4.6 L motors, and why the oil weight changed in the gt, gt500 and cobra r was with differant lash adjusters. He did dyno time on the 4.6L engine with the diiferant oils and found at high RPM's the heavier oils where holding the valves open and causing not only power loss but for the engine to lose rpm when compared to the 5w20 oil.
I forget what his final choice was but I am going to go through my engine books and find out his answer.

Well Ive got new lash adjuster to install my sound is only present when hot like the op states I've used a boroscope to look at pistions and and cylinder walls everthing looks great and I've also gt500 oil to try but unsure what to do,

Mine sounded exactly like that when I had a broken weld on one of my headers.
It was temperature sensitive too, just like this guy's. Cold no ticky. Hot loud ticky.
Casper cobra, do you still have the cast iron stock logs, or do you have tubular steel headers on the car?
tick means .loose exhast valve seat ..in my case.when it stopped ticking .few days later , i had zero compression on 1 cylinder
