advice when doing your diffs.. use a pump of some kind... it took me forever to gravity feed mine (20 min per bottle!!).. and a siphon wasnt strong enough to pull the oil through since its so thick, or if you need to gravity feed, get the largest hose you possibly can (think garden hose) i didnt realize that until i had no more fluid in my diffs.. also small things that are generally good to remember.. make sure you put the copper washer to seal your plugs up nice and tight back on... and always take the fill plug out first because you dont want to take off your drain plug to find out the fill plug is stuck/broken/whatever could happen to it

dunno if you planned to clean your pcv.. but dont bother, just get a new one.. theyre less than 5 bucks, i replace mine anytime i replace my oil filter
