I have no idea what you mean. Objective criteria should apply to all filters. If this person had reported that he was having trouble with excessive start up noise with a Fram filter every one would be blaming the filter. You know that's true. When it's a filter you guys like, it's a different story.

Talk about a lack of critical thinking.

Sorry for the short response. If someone blames a filter's(any filter) ADBV for one case of startup noise based on one case, I would disagree with them too. In the case of the Fram filter, this is something that has been reported many times, both here and elsewhere. I have personally seen tons of cars get louder after using a Fram filter, although it's not truly apparent if it is the ADBV that is causing it.

A filter that comes off dry after the engine has been off for a short period of time would be a better case for a bad ADBV.

It sounds to me that it's more of an oil flow or non-filter related problem to me.

Sorry, if I was overcritical of your remark, kctom, but it seems that you only show up, when you can talk about Fram filters.

The Mobil 1 filter is very good.

Cheers, Doug

Try the Seafoam. It will fix the start-up tick. It my come back but now you know how to fix it. The seafoam through the PCV is the only additive that has worked for me and every other Vortec that I Know of.

 

[Chris B.]

My engine noise is not really a tick but a "diesel" knock from the lower end. Is this what you are talking about?

I have never really messed with engines other then real basic stuff. Where is the PVC and how do I do this with the Sea Foam?

 

[Terry]

Chris, using the seafoam solvent will nuetralize the TBN in the oil so I would NOT use it unless you are going to change the oil in short order.

Having analyzed your engine and oil I do not think the Seafoam would assist in any way as you have no build up of any kind in that engine. The LC and FP are much stronger and DO NOT eat TBN.

Switch from the UPF44 back a K&N filter sized for this engine with this same oil to see if the noise dissipates.

I think we are on the same page about the anoying sound that comes from these new GM engines on start up.
The seafoam works best when the engine is HOT. When the truck is at idle pull the PCV valve out of the drivers side valve cover (it is back by the fire wall) and let the vacum "slurp" 8oz of seafoam (I use a measuring cup) take it slow as to not stall the engine. Then shut it of and wait about 30 min and start it up there should be alot of white smoke coming from the tail pipe and I usually run the engine between 1200 and 2000 rpms until the smoke clears the I take it for a drive.
On my dads 6.0L it took a couple cans to clean it up.

Keith-T,

Yes, I do only show-up when Frams are discussed. Your point?

 

[kctom]

Keith-T,

A point about critical thinking. No one would have ever criticised me by saying that I only show up when AC filters are discussed, or Purolators or Hastings. This attitude typifies this group. If you defend Fram, you are a trouble maker and not welcome.

THINK PARACHUTE

Thanks Terry and PM sent.

Thanks again to everyone who gave me input!

This first very scientific study was an eye opener!!

I am going to use standard Purolators Premium Plus ... they flow better than K&Ns and on top filter better too ... getting rid of my UPFs.

Amsoil looks extremly good here too and the basic Delco's are a great filter, but the Purolators Premium Plus are the best combo (take a look at the detailed flow and filtration spreadsheet within!!)

 

[Jim Spahr]

CrisB, I think the problem is that both of your engines have been know to have 'excessive noise on cold start' syndrome, as GM would state it. I think you need to address the noise problem, which may not be cured by a change in oio filters. It is generally thought to be piston slap. Go on the net an do a search for piston slap. Or better yet, go to the lists for your particular vehicles and look there for a 'piston slap' solution. BTW I own a 94 Impala V8 RWD and am a big Chevy fan and want a 5.3 Chevy truck, so I am not knocking the engine, NPI.

 

[YBSLOW]

I like the K&N if for no other reason the 1" piece that you put a socket on to remove it

Hey guys, As you can see I am fairly new to this site. I have seen the term "piston-slap" used several times and was just wondering what are you guys talking about. I would think is an engine had a "piston slap" issue it would be about ready to come apart. Someone please explain.
Thanks
Dave

 

[YBSLOW]

"Piston Slap" is generally caused by the way the piston(s) in the LS1 being slightly smaller than the bore when cold. They move laterally against the bore walls making slapping noises until they heat up and expand

 

[2004 F150 4x4]

YBSLOW, I don't doubt that he hears noise from his engine at start-up, but your definition of piston-slap leaves me scrathing my head? Not trying to slam you are anything but I don't see the pistons being to small in the bore and slapping the sides as being..... well for lack of better words..REAL. I can't see this happening the way you describe it. The only way i could see a piston "slap" is if the wrist-pins or connecting rods being severely worn and then you would damage some valves before too much time went by. Just my .02

Thanks for the info. I stand corrected.
Guess I'm more glad now than i was 2 months ago that I did'nt buy a Chevy!!!!!!
AND I say that having been a "Chevy Man" for most of my life. The new ones did'nt do much for me and now this. Un-Frigging-beliveable!!

I took this recommendation with me to the store last night and looked at this filter for my '01 GM 5.3L. It appears that this filter uses a black rubber ADBV. Comments?
