    If the oil filter you are using doesn't have a anti drain back flap (such as the OEM filter or if it's not functioning properly) you'll get valve train noise until the oil pump refills the filter and pumps oil back through the system. I would change to a different brand of filter and I'm running 5-30 synthetic. Eliminated cold start up chatter and eliminated the "sewing machine" sound at operating temp. Sounds much better and no difference in fuel economy.

    Be sure to use a filter with an 'anti-drainback valve'. I don't think the factory filters have them...for some reason...but the OEM Mitsubishi service filters do.

    Mine makes this noise, but for less than five seconds.

    I'm using a Hastings LF486 (long version of the recommended filter). I'm also running 5w-30 full synthetic Dexos1 certified oil.

    I'm glad you've said that. Whilst I can't speak for the one fitted at the factory, when I last did an inbetween-service oil&filter change, I bought a genuine one and noted that whilst it was see through, there was an anti-drainback flap covering the filtration media; as there was on the one that came out, though the clear flap was now stained black with oil. Both had the same part number (1230A105)

    What did surprise/concern me is how small the filter is. As soon as the warranty expires, it'll have a bigger unit installed, that's for sure!

    Baldwin Filters are available in the UK. B1402 is the standard size filter and the B1431 is the longer version.

    http://catalog.baldwinfilter.com/Par...rtnumber=B1402

    I use the Hastings LF486 (same manufacturer, different product line). which is the same thing as the Baldwin B1431.

    I made a chart of Baldwin filters that should fit our cars. You can find it here.

    i recant my statement. I cleaned out my garage and found my k@n wrench off in it's neat little box. i have an STP filter on which, now i remember, was free with a $18 gallon of "0-20 full synthetic for mpg vehicles" that i changed out right away after about 50 miles.

    "k@n hp1010" it said right on the box it has the drainback valve. my receipt said i paid $11 from o rielys which is a lot for an oil filter in general.
