is it normal for them to open just by reving it in neutral?
i popped my hood, and gave my engine a few rev, and i noticed the aux ports opening... both of them

 

Being in gear shouldn't make a difference. Sounds like they are working well.....lucky you.........

ah alright
i was worried that maybe since the engine wasnt loaded up
and if it opens
that there is a possibility for clogged cats, etc...
since its a S4 that uses backpressure and all...

 

mine aux 5th and 6th ports open as well in neutral but smoke begins to seep from them or around the area when i give it 3800 rpm+

what could it be?

 

3800 rpm is the secondary injector crossover iirc. I'd look into that, NOW. They're awefully close to that exhaust manifold.


Fuel+manifold=fire.

I'm not an expert by any means so just take my advice with a grain of salt but i DO KNOW that it's not normal for smoke to seep from the intake manifold or engine.....any part of it.

 

seriously i should check it out asap im not driving it as of now because its leaking oil like a ****, cooler or oil cooling lines...

 

Buy SS Oil Cooler lines from Corksport...one of the best investments I made for my car.

 

they actually open up tho, i think the smoke seeps from the headers...

 

its a 88 na gxl s4

 

while your messing with your 5th and 6th ports your should take a look at pineapple racings 5/6th port inserts ive herd really good things about them and there only like 50 bucks

 

thanks for the heads up!
