The mechanic that is helping me says he sees this type of leak a lot because people over torque the plastic part and it cracks, plus cold temperatures make it worse.I called around and three major auto parts stores shared, the factory part is no longer available and claimed it hasn't been available for a year and a half. So it looks like an upgrade is the only way to go.
The Dorman aluminum aftermarket part is very, very hard to get. If one does come in it doesn't stay in the store for more than a day.
Praying this is the only issue as that aftermarket part is expensive. I found the aftermarket part. $259.99. You need to buy the manifold set too, $51.99 easy to get.
The OEM part is listed at $424 WOW!!! $160 more for the crappy plastic part. Why even bother to see.
