89 CRX Si. One of my intake ports on the cylinder head is exposed by about a half inch. Manifold bolts up right to all of the other ones just fine but it leaves that one port open by about a half inch. I bought the car about 6 monthes ago and it hasnt given me any issues but i was just wondering if this is right or not. Also it has PM-6 and HF-6 written on the backside of the manifold. Mabye it's from a different car?

 

got a pic?

 

Nah, i'm poor no camera. It's inbetween the two middle fuel injectors. I can fit my pinky finger into it. when i turned the engine on and placed my fingers over the hole it didnt really do anything to how the motor worked. had a tiny bit of suction but thats about it.

 

Hmm odd its in between the in 2 center injectors where the gap is?
Do you have one of these?

thats okay, it's not a true intake port that is exposed, just a hollowed out place in the head. As long as it runs and you don't idle at 6,000 RPM you're good.
