hi i have in my almera gti strange noise after morning start for 1-2second i now is hydroregulators or somthing like that i dont now how is in english i had engine rebuild and this hydroregulators was proper vented have you got guys the same problem maybe this engine have like that or maybe oil filter is shit
 
If its a top end rattle that goes off after a second or two then it most likely your hydraulic lifters (hydraulic lash adjusters). It's not a really bad problem but if you've had a rebuild then the lifters should have been drained and refilled before refitting.

A bad lifter is a fairly distinctive noise, if its a rattle that starts with the engine and goes after a few seconds that's the chain tensioner being pressurized by the oil.

Replacing it can rectify this issue.
 
The lifters make noise all the time if seized or not bled properly. The noise you have at startup will be the chain rattling because tensioner needs oil pressure to work correctly. It's common on older tensioners and all of my Almeras have done it to some extent.
 
like rowdy when we rebuilt nistro's pnp'd head we fully submerged them and used a 2mm rod to actuate/refill them before refitting, an easy job during rebuild that saves problems later on
 
like Spyke said lifters make noise all the time it must be tensioner I was convinced is hydraulic lifters becouse we did something with tensioner when rebuilt engine but i dont remember we put old one or bought new i have to ask my mate. If i buy new tensioner noise will gone
