Oil filter

Live Long and Prosper.

So I just got through replacing the turbo on my WRX. What a PITA :banghead
Anyway, the Subaru dealer told me that the cheapo oil filters that the 'quickie lube' uses do not have a check valve and as such let the oil drain back out of the turbo and cause it to dry start and eventually fail, as mine did.

I was wondering if I could apply the same logic to my Metro. When I cold start the Metro, it runs rough as hell for 5-10 seconds. I am thinking that the oil is draining back out of the lifters and they are not pushing the valves open until the pressure comes up. I know it could be a billion other things, but I am due for an oil change and this is cheap troubleshooting. So my big overall question is: WHAT OIL FILTER should I use?

And, yes, I take my car to the quickie lube down the street for oil changes. The way I see it, for 22.50 they can have oil spill all over them and run down their arms and stain their driveway, etc. I'll get all greasy on more fun projects :D But if this oil filter is the culprit on both cars, maybe 22.50 isn't such a great deal :smackface

There should be a check valve between the block and the head that keeps the lifters from draining out. If the engine has been apart it may have been overlooked. Ken.....

M - 102 Oil Filter by Mobile 1. The K&N filter is the same except for the spot welded nut on the end. The nut has a hole in it for safety wire. Both filters have a thick can and are actually larger than the standard filter.

Some say...

Some cheap filters have a valve that is made from paper, which obviously isn't a very good material to use and will let oil leak past. Better filters have a valve made from neoprene, nitrile rubber, or butyl rubber.

I'm just not the trusting soul I should be when it comes to having others work on my car. I want to know what 5W30 synthetic oil is in it and what filter is used. ^o)

I bought a torque wrench from Harbor Freight that likely has a 3 foot pound tolerance but it's close enough. I torque the bolt to spec. At worst I drop the warm bolt in the pail when I remove it from the oil pan and fish for it, getting oil on my fingers. Gloves? Next would be the oil filter which I remove with a plastic trash bag. Kind of like how one might use a dog poo bag. :D

I know it's more fully drained and the filter was installed hand tight but tight and there was a film of oil on the gasket to make removal easier. But that's moi. ;)

Why?

K&N filter media allow too much debris through.
K&N flow better by having bigger "holes" for the fluid (air or oil) to pass through.
For example;
Wix oil filter, filters to 7 microns, where as a K&N only filters to 25 microns. (numbers pulled from @ss, used for illustration only)

Many new car and truck manufacturers won't warranty your vehicle if they find K&N on it.
I know Ford, International, and Mack all won't, I suspect most won't.
Ford and International want the fuel filtered down to 3 microns at the final stage of filtration. That's a pretty damned small hole for fuel to flow through and too small for water to flow through.
They love their injectors and you don't want to pay for new ones.
