Brian, sorry I didn't get the job correctly and thanks for your take on what the differences. My wifes Venture (3.4) had to have the LIM gasket replaced on it. GM priced it out at $2000 to replace. I'm going to help my son replace his as I can smell coolant when he pulls in the garage. However no way would I attempt this on a van. We wound up having Midas do it for $700 IIRC. Man was I ticked off about that.
