Do i need a new air dryer?

[trucklogger2]

Is it an older style dryer with a sniffer bottle? Maybe it is empty if there is one.
You can put half a bottle to a full bottle of safetybrake brand directly in air tanks also, this helps a lot. How about your purge valve? Easy enough to change.
Is your compressor discharging oil? Check when you dump moisture out of your wet
tank with pull cord or when governor stops compressor when it sneezes.
Add more in discharge line. If all this doesnt work, service dryer.

Theres a small metal ring in there look carefully...a new one is included in the kit butf the old one looks good I just leave it. Clean up oxydized metal before installing new one for a good seal.
