I was changing the upper motor mount on my 04 and noticed oil leaking from a switch kind of near the idle pulley. There is a small access hole through a bracket to reach it from the firewall side. Can someone please help me ID this switch and any special tools I might need? I'm sure if I know what to search I will be able to find what I need to know.


Thanks

It sounds like you're talking about the timing chain tensioner. It's on the back of the engine by the idler and tensioner pulleys, and you access it through a hole in the upper alternator bracket. There are two seals on it. One is a large combination metal and rubber gasket that seals the tensioner to the cylinder head, and the other is a small o-ring that seals up the plug that screws into the back of the tensioner. There's a good write-up on how to replace the seals here:
