Had the car up on the ramp today just to check over it and check for any nasties, none at all found which was good! Checked for the buzzing noise and think it’s coming from the pcv valve, I could just get my hand on it under the inlet manifold on the block breather plate and could feel it resonating with the noise, it’s not constant but I’m sure it shouldn’t be buzzing at all! Might have to give mr ford a ring about it, least it’s not another head gasket failure for them…….yet!!! Lol
