Nagging drip from just under the cylinder head...about one drop per minute. What's the fix, or just keep driving it like I stole it?

what is the story on the engine?? stock?? rebuilt?? mag cases?? case savers?? Mods?? From your byline, is it the 2.7 RS spec motor?? Looks like aluminum cylinders.
There is no gasket at the head to cylinder seal. Some engines were built with a "fire ring" compression seal. Most 2.7 builds probably have them.... but all bets are off if the head studs are pulling. Once they pull, you lose the head to cylinder clamping pressure and seal no workee. That would be my guess here. The only way to know is to pull the rocker covers and see if the head studs will hold torque. (might be able to do it in the car but I don't know and it would be a serious PITA). If they hold torque, you could drive on until they loosen again. If they do not - complete tear down is the only real fix. $$$$ If studs are pulling, continued driving is possible, but the sealing surface of the head will be getting beat up, requiring more machine work when you finally get it fixed. I guess this is why some do not screw with mag case motors. Good luck |
