I had one a week or so ago. Had crew handle comms, landed immediately and called for engineering support once on the ground safely.
We (engineering) pulled the chip plugs, found 'carbon' or nothing significant. Flush oil, clean chip plug(s), screen and change filter. Hover checks 15 mins and ops check satis - on our way. We also reviewed most recent SOAP sample, collected residue with a bit of sticky tape and white paper for trending and subsequently increased SOAP interval info. Carbon or fine powder like substance can be found on chip plugs, sometimes following some sort of engine work. Many Allisons and LTS engines had/have fuzz burners for that reason.
Checking chip plugs to make sure they don't look like a Christmas tree would be the first choice after landing though, after which you should automatically consider maintenance intervention or advice before further flight.
Now you're safely on the ground, you may want to consider the above for the future. I wasn't that remote but even in the Amazon (and I've flown down there - triple canopy etc), I would be a little more cautious than just checking oil levels before departure.
You're next landing may have been a little less controlled with only the buzzards to identify your entry point.
My 2c worth.
