I have a XR7 with a few problems. The core plugs on the 351 motor are all rotted through. Do you have to take the motor out to replace them?

You may have to drop the exhaust and the exhaust manifolds to access them. No i dont think you need to pull the engine to get to them but if you can remove them all and clean the freeze plug surfaces and reinstall them under the car then theres yer answer
