I just bought a used '00 s80 2.9(67K) and am getting paranoid with what i'm reading. I can do most of the work on this car except computer or engine rebuilds. The only problem I see is a little leak coming from somewhere near the dipstick but probably not the dip stick. Looks more like near that black plastic box near the throttle body(or the tube that connects to the engine). I've heard alot about flame trap's, is this box the flame trap? I've heard people say that the intake has to come off to get into this area but even though it looks tight, it looks like I could get to this area w/o taking off the intake. Any thoughts? Any same problems.

Don't mean to over kill on my 1st post but I want to change the trans fluid and nobody really talks about dropping the pan and refilling. Would this work?
Thanks, 1st time Volvo and Paranoid....
