    Thanks for all your help its very appreciated. Gathered up all the parts and tools for the head gasket replacement and will start tackling that this week as soon as I get through the videos and sticky notes of the forum.

    Since they don't sell the sub assembly parts im going to go ahead and order Toyota 25620-37120 Valve Assembly, EGR W/MO (website is just a reference to the part). I'm pretty sure by the diagram and "W/MO" in description it includes the motor part, Am I correct?

    I'm still wondering if the rewire has anything to do with it, maybe it is sending a faulty signal through the system and along with a a damaged ski jump do-hickey it is enhancing/escalating the problems.

    The most important part is to get it done asap.

    Thanks again.

    See if you can find the 04xxx- part number of a kit that includes that valve, it may save you a chunk of change. There should be several threads around here that mention it.

    Toyota sometimes will put a part and related parts, like gaskets, into a 'kit' with its own number, and price it lower than the thing by itself.
