I've put off this project too long I need to decide what I'm going to do...I've been sneaking around here for a bit now absorbing all I can, and checking out the IDI area on another site too. I have my first IDI, a 94 F350 Crew Cab 4X4 auto. It runs well, I must say I am very surprised with it power wise, having owned 2 strokers and some highly modified Cummins over the years. To the point: it has what I believe to be a leak associated with the oil cooler when it sits in the cold for any length of time. I have not been able to actually see the location where the oil comes out, but from what I've read and word of mouth I'm 99% sure. I may need to start driving this truck daily at the first fo the year and I don't know if I will have time to take on a project such as this, being I have no experience with these and I will be on a 2 week vacation at the end of the month. Is there a mecahnic in the northern IN/southern MI area that is reputable with these trucks that I could get a quote from? Any tips appreciated, thanks!
