There is a breather (I think it's a coolant breather) located on the top of your block, near the point where the block connects to the tranny. It is also next to where you would normally tap an oil pressure gauge to.

Could you please check where the breather conects to. Or if possible, post pictures.

Thanks,
Chris

 

Coolant breather?

I believe he means this vent on top/left:

 

I'm not actually sure what it really is.

It threw me off when I realized that the WRX motor didn't have it.

 

Yeah! That's it! Thanks Sean!

 

I believe it is just another crank case vent ...
