What is recommended for sealing the threads of the NPT connection adapters used on remote oil coolers and the oil cooler to the block connection.

I have been told not to use teflon tape or RTV as it might come loose inside and circulate in the system.

At least 2 people have said the brass should seat itself. I dont' want any leaks or weeping. If I wanted that I would ask a GM engineer.

Use a pipe thread compound like Rectorseal. It is used in the plumbing/heating trade to assemble oil and gas supply fittings. Teflon tape is used primarily on water connections.
