remove upper intake manifold

You may have to remove the upper intake manifold to gain access to the crankcase breather port. There's not much room with the manifold in place.

Sometimes the neck of the breather port is broken requiring replacement of the breather. If you take the time to remove the upper intake manifold you should consider replacing the breather. After 160K miles I replaced mine after cutting it open.

flat spring clip

Look at the second photo in post 2. The rusty thing on top is a flat spring clip. It has to be pushed aft to release the breather box. You may be able to wedge a flat blade screwdriver between the clip and the plastic ridge to get it started aft.

I wish I knew how to remove that crankcase breather. It just seems to wiggle. I need to swap one from one motor to another.

pry clip aft

Pry on the clip to move it far enough aft to remove.

Then lift the breather up and out. I think there is a O ring that seals the port on the bottom of the breather to the opening in the block. I think I used a small crow bar to lift it.

Well the first try ended with me busting the breather off. It seems to wiggle around a little but it doesn't seem like it wants to come out. Hmm...

clip removed?

I'm sorry that it broke!
Did you remove the metal retaining clip?
Did you remove the intake manifold?

Hey with 15 year old plastics things tend to break! I've got one more chance lol. Still have one from my original engine to try to salvage. I'll try to be more careful with it lol.

Yes clip was off and intake manifold too.
