Ok, I'm about to put my car back together and I just discovered that the banjo bolts that are part of the PCV system are different both in nut head size and in the physical end of the bolts.

One banjo bolt has a 17mm head and some sort of jiggle thingy inside of it.

The other banjo bolt has a 19mm head and does not have anything inside of it.

One goes to the intake manifold, the other goes to the head on the driver side of the car.

I thought they were both the same until tonight when I started getting things ready for tomorrow's rebuild.

Any help on this is and will be greatly appreciated as I don't want to put the wrong banjo bolt in the wrong spot. My current hunch is the 17mm goes in the head, and the 19mm goes in the intake manifold, but I need to know for sure.

Thanks in advance,

Matt

      Yes, by process of elimination:

      17mm head bolt goes into the intake manifold. Why? Because it was greasy and it part of the PCV system.

      19mm head bolt goes into the head. Why? Because it is part of the water jacket that flows from the head to the thermostat.

      I saw a drawing that highlighted both paths of the hoses and with the one being oily and greasy that made sense to me, so there you have it.
