A riding buddy of mine had somebody do the head gaskets on his '98 Ranger V6. When he got it back, it idled high and the check engine light was on. I looked it over and found an open vacuum port between the heads on the back of the intake. Plugged it and his running problems are solved. Then the next day he calls and his 4x4 is inop and his heater won't change modes correctly. At the time I plugged the vac port off, I looked for the hose that ought to be connected and couldn't find it. So, on Christmas day I was over at his place and we checked out the truck again. I found the vac line from the axle to the reservoir under the battery, and traced the lines from there into the firewall near the heater. I can't find a disconnected hose anywhere, and the Chilton's book he's got is next to useless in this case. The only thing I haven't checked was anything coming from the transfer case. I was dressed too nice to crawl under it in the dirt the other day. Anybody know where the vac line for the 4x4 goes from the intake?
