D-max 4JJ1 engine - cold start up noise

[FreeWheelie]

Greetings from Germany, 4JJ1 3.0 turbodiesel, 140.000 km
since I own the truck (1 year) I noticed a rattling noise at cold start up for about 3 seconds that stopps exactly when the red oil light goes off.
I am thinking of the timing chain tensioner, cause the noise reminds me of a rattling chain.
Is this normal, mayby YES ???
Many Thanks
Dirk

Yes it's the timing chain and yes it's normal, they run a tensioner on the chain that is oil feed

thanks for the reply, so the chain and tensioner should last as long as the engine?

If the noise last for longer say about 5 mins, would it be still considered as normal ?

If it lasted as long as a minute I would worry
