So I have a 2007 Kodiak that broke a piston @ 229k. Got a new used motor from a 2006 Kodiak 5500. So the engine is whole and has 73,000 miles. I use the the Kodiak to tow a 10-12k enclosed trailer. My questions are what should i do while i have the motor on the engine stand? I see all kinds of up pipes and oil pans, injector mods. Really its running a mild EFI Live tune. The one thing I have planned for the truck is a external oil cooler from experiance oil temps seem to run away and take time cooling down resulting in low oil pressure on highway runs. This was all on my old motor but we saw the same thing on another Kodiak I borrowed to pull my trailer.
