This is prolly a normal sound but I am not sure so I will try to describe it as best I can...
When cold (sat overnight) I start it up it sounds like the valves rattle loudly for about 1 second (louder than say 5K miles ago) and the goes away when I think is after the engine has built oil pressure, is this normal?

 

Is there any way that you can take a video with sound or just record sound and put it up for us?

Otherwise people can just throw out crazy ideas from your car is perfectly fine to oh my god it's going to blow. Just to general to try to say anything.

 

Your correct, I will have something Monday night when I get home from work.

 

A rattle sound that disappears when the engine warms up is consistent with a faulty timing chain tensioner. There are a couple of active threads on this subject right now. Perhaps that is it. If so, since you have an '05 it should be covered under your new car warrantee assuming you're not over the mileage limit.

 

Some of us have been able to eliminate valve train noise just by switching to Maxlife synthetic motor oil. It might be worth a try for you.
BTW, keep working on your spelling. English is a difficult language to master but is worth the effort if you want to live here.

 

see this all too much...

 

Well, the sound goes away in a second or two, still think it is chain tensioner?

 

absolutely...makes noise for a second or two then abruptly stops.

 

Does it rattle if you turn the engine off and re-start after the engine is warmed up?

 

Don't know, have not tried that yet. Give me a couple of minutes.
