Quick question/Exhaust Manifold

Ok, I got the thing off, replacing gaskets to fix leak (hopefully). Putting it back on, the service manual says 26ft lbs of torque.

Now, do I want to let it get warm and then retorque? or am I just g2g after it's installed and torqued down?

Thanks,

i always go back over it and make sure its still tight. not necessarily when its warm but the day after or so.

 

that's what i figured, thanks

 

didn't fix it...that's it. I'm all out of ideas. F'n car.

 

you got a exhaust leak? do you know its coming from your headers? there is a lot of gaskets on the exhaust system. if you replaced the leaking one and still have a leak it probably wasn't the leaking one and there is more.

 

I hit peak boost the other day and heard my exhaust get louder...like a leak louder. But, I've been trying to find a vacuum leak for 2 months now and I can't find one in any of the hoses. So, I replaced all the manifold gaskets and crosspipe gaskets. So, they're all new now, but I think I still have vacuum leak and it's really starting to piss me off.

 

It's probably not the exhaust manifold then. Inspected the TBE? Intercooler Couplers? Turbo?

 

The tbe looks fine from what I can see. Haven't looked at the turbo really. I've taken the IC apart and put it back on there a couple times lately with the same results. Things looked good in my opinion.

 

Sea foam!

 

I've tried it...and didn't see anything...except for smoke, but not out of anything except the exhaust. :-/

 

Then are you sure you're hearing a leak or going parnoid?(Seems to happen to me alot) After what did you start hearing this leaking noise?

 

list all mod list

 

Although I don't have a lean code anymore, I am running lean. I've been logging with learning view tool, and my learning is all jacked up. I see 14.99 at idle (#A).

It's not that I'm hearing it...it's just there. I heard it the other day when I went WOT to test my peak boost, which I am hitting. After replacing the gaskets today, installing whiteline steering rack bushings, and installing my perrin front sway bar, I went for a test drive. I went WOT and didn't hear any fluctuations in my exhaust. It sounded like normal.

But, I am still running (false) lean, due to a vacuum leak somewhere which I cannot locate.

I do have leaking Valve Cover Gaskets. Which I have the stuff to fix it with, but I'm not really sure I want to do it. Looks like too much friggin' work for a noob

Not that the suspension ones mean much, but yeah.

I have replaced the fuel filter, PCV, Exhaust Manifold Gaskets, BPV Gaskets, TMIC Gaskets, Cleaned the IACV and replaced gasket, Sprayed carb cleaner on vacuum hoses, swapped MAFs/front o2, used seafoam, inspected hoses...etc. I'm all out of friggin' ideas and it's realllllllllly pissin' me off.

also, the car just smells rich. I could probably light a match behind my exhaust and have a pretty sweet blowtorch :-/ Should the inside of the headers be white-ish? Mine are, just wondering if that's normal.
