Engine bay. I never clean it. But I am going to when I get back from vacation, dammit. Especially since I have a couple modifications going in.
And suspension. Ride has gotten a lot rougher, I've poked around a little but I really need to figure it out. I don't see struts leaking, and they were bought used but tested by Koni and they passed. I guess that doesn't mean they couldn't have gone bad since then, since it was over a year ago.
Oh yeah, and my driver side CV boot ripped and dripped axle grease on new pristine rims I just installed. That will get cleaned also though.
