meh! the crush washer is nonsense!
just another scam to extort another 2$ from you pockets.
You dont need a new crush washer to form the perfect seal. The drain bolt alone will do it and if you already have the old crush washer, that will seal time after time till the end of time. Dont be a slave to "hear say"
try it out for yourself and end this "need" new crusher non sense.
10 cars so far, never changed the crush washer on one of them including my 2 NSX. Just turn it tight. The oil usually stops after the plug goes in for the first turn, the tread design is made to hold off the oil.
Same applies for trannys, never had one leak on me yet.
Short filter work. Just dont put it on too tight. I hate machanics that tighten the filter too much. When the seals match to the seat, turn it 1 rotation and that's all you need.
make sure the prvious seal is on the old filter when you take it off or you got the new seal sitting on the old seal and you get an instant oil leak and loss of oil pressure and end of engine.
other then that, pretty easy job. If you dont have a lift you can do it by jacking up the passenger rear jack point, work lose the bolt, put a low profile pan under the car, drop the jack so that the car is almost sitting on the oil pan so you can drain out as much oil as you can. Jack up the car again, put back the plug, and get the filter.
You dont need to take off the wheels that also rubish. Should take less then 10 minutes unless you come up against a tight filter.
If the filter is really stuck on and you cant get a oil filter clamp to work around it, you can also tap a screw driver right though the filter then use that extra leverage to twist it off.
good luck.
