Default Cost of intake manifold

Not sure if I need the whole manifold or just the gaskets replaced but just wondering what I can expect to pay if i have a shop do it for me.

There are multiple threads discussing intake problems and replacement. In my case, I wasn't sure if I had a leaking gasket or a cracked intake manifold (anti freeze on coil #1 and system too lean - bank 1&2). Since my intake was 12 years old and had 160,000 - 170,000 miles on it, I figured it was safe to assume if the intake wasn't already cracked, it might be after re-torquing. That's a lot of heat cycles which could make it brittle.

Mine did the same thing in the same place. Not exactly sure on the cost but am thinking it was around $600 but could have been more.

I just sold my leak free 2003 pi intake for 70 bucks shipped. Gaskets are around 60 bucks.

. Actually I have been reading this one today and it helped a lot with finding out what was wrong. Pretty sure I could get it apart and new manifold on it's the putting back together that I'm not so sure about

Torque specs for intake manifold - 18 inch pounds for all 11 bolts, then again to 18 foot pounds. Sequence as pictured:

So anyone else got an idea or know how much this would cost? also I thought it was my heater core at first cause I was getting what looked like coolant spots on my windshield when the defrost was on, would the intake cause this too?

Shop quoted me $900 For intake manifold replacement but knowing him, that would include water pump replacement too since he was that far into it. A guy who does mechanic work as a side job said $600 to replace it - including the cost of the intake.
Rock Auto has them for about $164 and it includes all required gaskets already installed, a new thermostat, and bolts for fuel rail and coil packs.
