Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

    Coolant Leaking

    I have a 2003 Grand Prix 3.1 that has been losing coolant, so I just pressure tested my cooling system and I can see a leak. The only problem is I'm not sure where it's originating from. If i'm standing in front of the car, the oil pan is on the right, and the dripping is coming out just to the...

    Cylinder Head Resurfaced, What else?

    I'm getting my cylinder head pressure tested and resurfaced (as i think it's the cause of my coolant leak and white smoke from the exhaust). Should I have anything else done to head? Valve job etc? I have a 2003 Grand Prix SE, with 90,000 miles. Thanks.

    Smoke from manifold/exhaust

    I was loosing coolant and white smoke was coming out my exhaust, so I replaced my head gasket, LIM Gasket, exhaust manifold gasket, valve cover gasket etc, but i'm still having some issues.

    stripped threads!! Replace gasket??

    Dirty Pistons - How to clean?

    I'm replacing my head gaskets, LIM gaskets etc and my pistons look really dirty. What's the best way to clean them up without causing any damage? I'm no expert, so this may be normal, but I have attached pics of the cylinders. Thanks.

    Removing Exhaust Manifold

    Looking for opinions on if it will be easier to remove the exhaust manifold from the head, or the pipe from the exhaust manifold. I am trying to replace the head gaskets, and I am one step away from getting to the rear gasket (front head is already off). I am worried about breaking off bolts...

    Can I remove motor mount torque struts?

    I am trying to replace the head gaskets on a 2003 Grand Prix SE, and it looks like the motor mount torque struts, at the front of the engine, bolt on to the head. If I remove them, will the engine roll and possibly get damaged? or is supported elsewhere on the engine? What do I need to do to...

    Where can I buy Upper Intake Plenum?

    I need to replace the upper intake plenum on my 3.1 2003 Grand Prix. Where can I purchase this from? Would it normally be stocked in a retail store like Pepboys or Autozone? or should I try and get a used one at a junk yard? Any online places that sell them? Thanks for your help!
