Start-up Noise with PureOne

I know this topic has been discussed before, but I have a few questions.

I currently have a purolator pureone installed on my Saturn SL1, I have noticed when I use these filters, instead of their classic counterpart I get a start up rattle after the car has sat for a while.

My first question is.. any idea what causes this? I can use a pureone, go to a classic, and back to a pureone, and the sound is only there with the pureones and not the classic.. I assume its because since this is a higher efficiency filter it may take a little longer to start pushing oil through the filter element? I dont believe it would be ADBV since this filter has a silicone ADBV.

Second question: Should I even worry about this? Its literally there a split second then gone, no oil pressure light or anything shows on the dash. My biggest concern is that my timing chain tensioner is controlled by hydraulic pressure, is it possible this brief lack of oil could cause it to skip a tooth and cause a whole slew of issues? Other than the timing chain, I dont feel like there is much harm that could happen to the camshaft or valve lifters because in theory they should have a protective oil film on them from the previous run.


I do want to mention I am in no way trying to say this is a bad filter, I have just noticed its there with one type of filter and not the other. Besides for all I know my oil pump could be aging and not putting out its full potential flow for a high efficiency filter. I am more concerned if this is could cause damage, and little curious as to why these filters cause this noise.

Thanks!

My uneducated guess: the P1 is slightly more restrictive and forces the bypass to open ever so slightly. The rattle you hear is the metallic bypass moving up and down because as soon as it opens it wants to close again.

What ambient and oil temp does this occur at? Any?

Does this happen with warm / hot starts? If so, then the oil should be flowing enough not to bypass so it's some other filter characteristic, perhaps harmonics.
 
Your oil pump just takes a sec to get the oil moving is all. No one here can really do anything but guess,which is what I'm doing.
What type and grade of oil? Does it get more pronounced as the miles rack up or is it consistent through the entire oci?
Is the engine high mile? Could it be that you may benefit from an oil that starts off with a 0W?
If the noise is more pronounced as the miles rack on it could be oxidative oil thickening. If it's all the time but is eliminated with 5w or 0x you could try that.
Or you could ignore it. Chasing this noise isn't going to extend the life of the vehicle. Your engine will sound exactly as it does now in the junk yard once the rusted tower mounts pound through into the trunk,or something else rusts out.
If you don't like the noise use the filter that deleted it and stick with it.
A classic will run 10000 miles in a clean engine so if you've kept up with maintenance use a classic and enjoy the peace and quiet or use whatever and turn up the radio.
Either option is fine. Your engine's longevity is unaffected either way
 
Well, how can that knocking noise be a good thing ? I know you're curious as to what component in that filter is causing that issue, but does it really matter ? You've clearly established that it is causing a problem. If you have a P1 on that engine now you need to take it off and not use it again. It's that simple.

I have the same symptom when using the P1 on my Ford 4.6 V8s, which why I don't use it anymore. (Noise with the P1 is a known issue on the 4.6 that many, but not all, owners experience.) If I use the Purolator Classic or the Motorcraft I have no noise issues and no worries. I really like the P1s and want to use them, but the Classic and Motorcraft are more than adequate for the 5,000 - 6,000 mile OCI that the Town Car is on.

It's generally accepted that something like 70-85% of the wear and tear on an engine in the typical daily driver occurs at start up. So why add to that ?
 
Believe it or not, I have had my share of startup noise with the P1's even compared to the Classic's but, they've been fine lately...No Noise!
 
I think it has more to do with the Saturn engine than the filter. My SL1 rattles occasionally no matter what filter is on it. Right now I'm using a Fram ph8316 that seems to have an improved ADV. It still rattles sometimes, but less often than with the Purolator Classic or Napa Silver.

I wouldn't worry too much about it. Your engine has survived 14 years and will likely go another 14

This morning it didn't rattle after sitting all night in the mid 20s.

Yesterday when it rattled, it was on a sorta steep incline.. maybe that didn't help things.. it doesn't seem to happen every time. However the first time I used a P1 it happened every time, and this was back in the summer.

I think Ill continue to monitor, and if it keeps doing it ill make this a short oci and @ 3k miles ill change the oil and use a different filter.

I was asked what the oil is, sorry I didn't mention before, its Valvoline Max life 5w-30 this is a fresh oil change, only 200 miles on the oil so far.

Filters can definitely make a difference on different vehicles. I've had a long post history discussing that issue on my Jeep. There is no rhyme or reason to which filters work well and which ones don't (most of them don't) it has just been a trial and error thing.

Despite multiple attempts the PureOne has been one of the worst offenders for me.

The winners so far, Motorcraft "S" series, Fram Toughguard and the Napa Silver, all three of those are different set ups so there is no real pattern. Some just work and most don't.
 
I am aware of the issues you have had and that the fl-400s was one of the filters that cured your issue. I think I will use the fl-910s if the noise continues to happen. It seems like you just can't go wrong with a motorcraft filter.
 
I think I read that Amsoil tested the Motorcraft filters and came up with 93.9% efficiency. But when I checked my dipstick at 2500 miles the coloring looked really good compared to other filters I have used including the TG3600 and the Classic L20195. I wish there was an independent lab (unbiased) that would test the Motorcraft filters.

I'm thinking Amsoil had an independent lab to the ISO-4548 testing. Doubt they have the lab equipment to do it themselves per IOS testing standards. They don't even make their own oil filters, so I highly doubt they have their own sophisticated filter test lab.

+1 ISO-4548 is the industry standard and quite frankly the Amsoil MC efficiency test result did much to prop up the MC opinion here because of it's previous vague (but low) efficiency rating. I have no reason to doubt the integrity of the results, very respectable for the MC.

Otoh, Honda and Toyota oem fans might not be so thrilled.
