Oil Leak
I have a 1978 F150 with the 400 motor. I recently discovered an oil leak on top of the motor just behind the intake manifold that looks like it is coming out of the oil sensor. It is leaking pretty badly. Would it most likely be coming out of the sensor? If so is there a replacement gasket or do I replace the sensor all together? Or could this be leaking from some place else?
Thanks for the help,
Dett

could be the rear manifold seal. you could plug the oil sender off to determine which it is. my bet is on the intake-

The sender unit just unscrews although it can be tough too get at the nut under the housing. If it's wet it's most likely the culprit.
