Don't know the code yet, will probably pick up car tomorrow, and will hopefully be able to pry enough information out of dealership to get at it. Has been a bit tricky, since lose the code every time the battery dies, and I've never bought an odb2 reader myself.

And, I'll have to check where the leak is coming from, dealership said it was still leaking, so it sounds very likely that the breather covers are the issue. Thanks to ala_xfire's links, saw this guide (https://www.crossfireforum.org/forum...over-leak.html) so at least I know what to look for now, and can figure out if that's the real source of the leak. Fortunately, my local mechanic (not the dealership) did the valve gasket replacement, so it wasn't ridiculous.

Yeah, I've got a lot of choices here in Denver, not planning on trying that dealership again. Really, should have just came here first. This has really been a great forum, with great folks, first found it after dealership not being able to figure out engine start issue, even after several months, and then finding the RCM fix here. Been grateful ever since.
