eric the dutch 0 Posted February 13 I drained the air tanks and out of one air tank came first water and after that oil and I'm talking about a pole of oil. Out of the wet tank was water first and it turn in to air....what can be the problem..air dryer? compressor piston rings? or something else....I just bought the truck and I don't know how long it was sitting still...its a 2005 rb 688 Share this post Link to post Share on other sites

eric the dutch 0 Posted February 13 thnx for your response...like I said i just bought the truck and I don't know when was the last time.....I will drain it for the next couple days and lets see what happen Share this post Link to post Share on other sites
Ezrider 351 Posted February 13 most the time means its time for a new compressor. if its a new to you truck i would drain and monitor for a while first. could also check your turbo for blowing oil too. but every time i have personally seen a lot of oil in the air tanks a new compressor fixed the problem. a compressor that is passing a lot of oil will ruin your air dryer cartridge as well. 1 Share this post Link to post Share on other sites
turckster 85 Posted February 17 An air compressor will pass oil if the engine spends too much time at idle. It is always best to bump them up a few hundred rpm's. Share this post Link to post Share on other sites
