Very little oil in the cannister on my 380SE. Also the copper washers that come with the filter would be for drain plugs if you change oil from underneath. The small silver washer is for the bolt that goes into the cannister. I usually disconnect the plug wire from the ignition control module which is same wire that goes to the coil(I believe) I then crank a the engine in short bursts about 3-4 times and this eliminates the chain clanking noise and ateh pressure is right there. However, I just changed oil this week and did not crank engine long enough and did have the clanking for about 2 seconds and then it smoothed right out. I hate athat sound and my stomach goes into knots when athis happens. I just have to remember to crank longer.

By the way my wife's Cadillac SRX does this sometimes when it is first started after sitting a few days and if cold out.
