    I am not sure on the 3800 but on the 3100 it is below the manifold. good luck

    Look on the cylinder head closest to the firewall. It sits below the manifold, about a third of the way back from the front of the engine. Best way I ever found to get to them is from underneath the car, and even then, it’s not much fun…

    Whatever you do, don’t try to use a crescent (adjustable) wrench to take it out. All you’ll do is break it, and pay someone else to fix your goof.

    Been there, done that, got the t-shirt…
