OK OK OK, so I have been swearing up and down that this thing will work in a 12v (looks identical, and installs without any trouble) great choice because it is MLS construction. Well... ... ... It does not work. there is a small oil passage (on the pressure side) that pukes oil into one of the water jackets. Nothing like putting your truck back together and running it for like 30 seconds and getting a radiator full of oil and a pan full of water
needless to say I was ******... ... But at least we all know for FACT that the MLS gasket from a new HO will NOT work,
I tried to come up with somthing that I thought would be revolutionary to the 12v sceen, but I guess we will have to wait for someone other than cummins to manufacture a MLS gasket for the 12v. Until then, I guess O-rings will have to do. Please spread this info and save others the hassel! I will have a write up on my truck soon including the HO gasket whoes!
