My 1995 powerstroke has developed a tremendous oil leak. I believe it is coming from the long tube like thing on the drivers side of the engine block (oil cooler maybe?) Does this tube have o-rings on the ends of it? Are they known for blowing? How hard of a job is it to change? If this is not an oil cooler what the heck is it? Thanks Jake

 

Yes, that is an oil cooler. And, it has o-rings that can be changed.

It is not all that hard to change the o-rings, but you will probably make one heck of a mess (both oil and coolant will come out when you remove the cooler).

You can buy a kit with all o-rings and gaskets for the powerstrokeshop.com for like 30 bucks. I just changes my yesterday. its not hard but is messy. For what I read they leak alot. My o-rings was hard as a rock.
