I'm towing my trailer on vacation, I routinely check under the truck after some long pulls. I see oil sprayed all under the truck on the passenger side all the way to the back of the truck. I had the oil changed just to make sure the oil filter wasn't leaking. So now I can still see drips coming off the A/C compressor. What could be in that area that could be leaking, I've crawled all over and I can't seem to locate anything. Also if I need to have some work done I'm currently in Calgary Alberta, does anyone know of a reliable shop I could take my truck to? Thanks

 

check the fitting on top of the filter housing(it supplied lube oil to the turbo)

 

When you took the old filter off at you last change, did you make sure the old seal came off with the filter? I had the same issue once, it was because the old filter gasket was stuck in there. It, in conjuction with the new filter, resulted in a leak. NEVERMIND- I just noticed you HAD the oil changed. I'll bet the knucklehead that changed the oil left the old seal on there...

 

Thanks guys for the replys, I checked the top of the housing and it seems to be dry, but there is a 3/4 to 1 inch line that runs down along side of the oil filter that lookin kinda dark, I just can't make it out what it could be. Still searching, I have found a few options to check for shops, but theres no way to know until Monday....
