From my research, it appears that high quality filters all feature bypass valves at the back of the filter much like how they have anti-drainback valves at the opening. The thing at the back is the spring retainer as the spring keeps the filter media and valve in place. The design can vary from filter to filter.
That being said, the photo above of the Mobil 1 filter may be of an older model and the new ones may have a design much like the OEM filter. I'll have to check the M1 filter I have on my shelf for the next oil change.
However, the valve at the back is for bypassing filtration when the oil filter media cannot filter the oil well enough. This leads me to think it will not have much do with valve train noise on start-up with oil in an engine that's not neglected. The anti-drainback valve would seem to be more important in this regard than a bypass valve.
I don't have the start-up noises you are talking about and I've used the Mobil 1 filter for my last 2 oil changes. Perhaps I have a newer version of the M1-103 filter or maybe it was your oil and filter condition at fault. Hard to say.
I'm curious to see what the OEM filter's insides look like. Let me know if you have spares and take photos if you can. Thanks.
What Did You Do With Your Kizashi Today?
Grr!!!! I park on the moon too anywhere I go, and this type of thing still happens. I actually had to shell out over $400 when someone hit the rental car I initially had in MKE and took off.KuroNekko wrote:Anyhow, I after rinsing the caked-on salt residue and dirt off my car, I noticed an unpleasant surprise: a scratch on my front bumper. Mother Fu....
It obviously looks like someone backed into my car sideways or something. I merely could not see it until the salt residue was off of my car.
So pissed off.
Anyhow, I did what I could with the touch-up paint I got a while ago. I didn't want to make an insurance claim given the damage was minor (scuff marks and scratches) and did not want my car in a shop.
It looks a lot better, but still pissed that people suck at driving/parking and hit other people's cars. You have no idea the lengths I go to to park away from other people yet I still get hit. DC drivers...
If you love your car, stay the hell away from this city.
Anyhow, here's the before and after.
Before:
After:
On my site, we even had a multi-page thread about this topic. I'd like to baseball bat someone's shin in return for a door ding--at least that would let them know what it feels like to we enthusiasts.

Did you try to use a clay bar or something to get off what you could? It looks like it was etched in there, so clay might not have done anything.KuroNekko wrote:Thanks.
It's more noticeable in other angles, but not unless you are close. The touch-up wasn't the best job but it worked and looks a lot better than before.
It sucks when you do your best to care for your car and someone else just carelessly damages it. I got to be more relaxed about it as these things are inevitable but it's hard when you really like your car and want it to last a long time and look good doing it.

I've gotten more relaxed about this as well. But as two of my advertisers found out when I was meeting them in the Porsche to photograph a new piece of their work, when I discovered that someone had hit the Porsche with a yellow car in the rear panel, I'm sure the entire strip center heard me scream mother...
Luckily, one of my advertisers was a detailer with some rubbing compound with him--everything came right off with no dent.

What the heck? What's this world coming to?

I've thought about getting one of these for all the hit and runs here in MKE. I hate street parking because of this.krell wrote:You need this, it work for me in NYC
Today I caught up on Kizashiclub, checked tire pressures via my tpms tool, got the rear shocks replaced under warranty (which were rusted), saw the warranty repair job on the wheels (which was okay as I saw at least two dirt particles in the finish :\), got a free factory oil change, ordered Bridgestone RE760 tires, and checked the oil level after the oil change.
Whew! What a Kizashi day!

Na, I did not bother with a clay bar as some of the scratches were well beyond the paint and into the bumper's plastic. It was deeper than a surface scratch on the paint. The good thing was that it was rather small in area so the touch up paint hid it well.
I want to note that the Suzuki dealer in my area did not carry touch up paint. They claimed they could order it for me, but stated it was actually from a third party, not Suzuki. I then ordered some from a site recommended on this forum. Color was a perfect match. It looks like they also can make you spray paint cans of the body color. Hmm, that could be useful.

I'm wondering the same thing. I know you can go through the clear on a normal car, but I'm sure it's even easier on our cars.bootymac wrote:Which products are you going to use? The Kizashi's paint swirls like crazy and I'm wondering how aggressive I should be with my DA polisher

Possibly, but there was definitely a difference in design between the Suzuki and Mobil 1 filters.bootymac wrote:Sounds like he's talking about the bypass valve, which can be in different locations for different filters. The bypass valve doesn't help with start up noise though. That's the function of the anti-drainback valve.
My point is while the OEM filter is ideal, it's unlikely that it contains anything different from a quality aftermarket filter.
The quieter start up is probably from the fresh new oil
The quieter startup could be from cleaner oil, but the noise was there even with only 2k on the oil. I'm just happy that it buzzes more smoothly now.

Thank you for posting the link! That might come in handy. I forgot about a bubble on the rear quarter of the car from the day we bought the car (previous owner even pointed it out before we bought the car). Steve said it looked like a 'paintless dent removal' that wasn't done right--so no warranty coverage.
