We have sprung a leak in our 65 Coronet 318 Poly and I would like some information before tearing it apart. It looks like there is a hole through the timing chain cover at the water passage on the drivers side. I have a replacement cover in case it is more than a gasket problem, but my shop manual does not include details on the engine. I cannot tell if there is a seal in the cover that goes over the nose of the crank shaft. Can anyone tell me if replacing the timing chain cover has any hidden complications?
Thanks
