Question about 1997 Nissan Pickup
Sounds like a timing chain issue, eventually the tensioner builds enough pressure to quiet it. Also check all chain guides, they get damaged with chain noise like what you describe.

Could be worn timing chain guides.

A worn timing chain would likely get noisier as the engine warms. If there are chain guides and they are worn, then so is the timing chain as the slop in a worn chain will cause wear on the guides.
Also consider piston slap which can be cured only in an extensive overhaul.
Likeliest problem is worn rod bearings causing a knock against the crankshaft because the oil drains out of the bearings after a long period and cannot provide a lubricating cushion. Cold oil entering the bearings will silence the knock as soon as it reaches the bearings.
If this is the case, an overhaul is the sure fire cure. However, since it's an older vehicle likely with a ton of miles on it, just take good care of it and it will take good care of you. Change oil and filter regularly, let the engine warm up for a couple of minutes before taking off. No hard driving under any circumstances, and don't loan it to anyone who may drive it like they just stole it.
