Watch out for K&N oil filters
Just bought one of these oil filters part #2002 I think.Go to put it on and it will not screw on.measured the hole and it was lik a 1/16 too small.Took it back and had the guys at autozone double check the part # and cross reference it to all the other filters,mainly the ac delco 454 I`ve usually used and the part number was correct according to theire computers.Checked some other brands and they appeared to have larger hole at a glance.The 454 delco screwed right on.Sorry if I missed a post like this before just thought I`d share.pretty weird.

Re: Watch out for K&N oil filters
I have been using the 2002 filter as well and have yet to run into that issue.
Might have been a "needle in a haystack" misrun part or something.

Re: Watch out for K&N oil filters
Do K&N oil filters have the part numbers on them? I'm thinking the filter was in the wrong box.

I think it was the wrong box. I too used it when I first got the car but figured it wasn't worth it after a while..

Re: Watch out for K&N oil filters
i use the long one i think its a 3002 but never had that problem
but i havent ran a K&N in a year, now using M1-302's (mobil 1) because advance auto offers 5 qts of mobil 1, and a mobil one filter for 29.99 once every 3 months it seems, i keep stocking up on it every time its on sale

Re: Watch out for K&N oil filters
I always use K&N. Last month I was changing the oil in my silverado and the oil filter wouldn't fit. It was the first time thats ever happened. I think it was a factory reject or in the wrong box. I swapped it out for the same part number and it fit fine.

Re: Watch out for K&N oil filters
I`ll check out the 3003 next time.The 2002 was almost twice as deep as my delco 454 though.Thats why I wanted to use it.

Re: Watch out for K&N oil filters
You guys havent read into the new corvette and GM engine designs (but can work on ours).
Having a smaller oil filter is actually better for the motor because instead of the oil sitting in the filter all the time or as much as that sits in there total, it is running through the motor lubricating all that needs it.
So technically more oil sounds like a good idea, but only if its going through the lubricating system. So a smaller oil filter gets the oil in, filtered and out right away whereas the bigger filters store more in the filter thus meaning that oil isnt being used in the system but rather staying in the filter.
Look at a Pontiac G8 filter size as well as the new camaro and corvettes. They are all mini filters. Smaller than our stock filters and way smaller than the 3002 some are using on here.
Understand? Its actually some what common sense. A larger oil pan would be better for more oil than a bigger filter. As at least that oil is being used in the pan.

Re: Watch out for K&N oil filters
why not add more oil if u use a bigger filter? oh well gm has more money for research then i do. But then again maybe its just another way to get us to spend more money on repairs. They seem to spend more money on that sort of thing today then yester years.

Re: Watch out for K&N oil filters
YOU DO add more oil using a bigger filter, but what I was saying is all that extra oil ends up just sitting in the filter anyway. Whereas if you had a deep pan and a smaller filter the oil would gets its use in the pan and not just sitting inside a filter.
BUT this does not mean go out and buy a 1" filter, you still need size for filtering, just not 5-6-7" of it IDT. The 3002 K&N is 5.52" and stock is 4.6". I may go to a 4" filter, but after I get my oil temp/pressure gauges upgraded so I may take tests of my own.
Take care as usual.

Re: Watch out for K&N oil filters
this is off subject but my oil pressure is really low at cruising speeds and goes to zero when in neutral or park. any ideas on what might be causing this? I changed the oil and it has enough oil

Re: Watch out for K&N oil filters
is pn 3002 just a taller filter, thats all? in terms of having a bigger filter being better i think the advantage to it would be greater surface area for filtration.

Re: Watch out for K&N oil filters
what kind of oil are you running? check your sending unit for leaks, and put 20w50 in it.

Re: Watch out for K&N oil filters
now matter how much oil you got the same amount is in the "workings" of the motor all the time, if you have a 6qt pan all you got is extra oil, yea thats a good thing more oil in the system has it bennifits, but the fact is the same amount of oil is in your valve train no matter what, the 6qt compaird to a 5qt well that extra quart is going to be just in your oil pan it aint like your going to have extra lubercation, the tall filter just lets you put an extra 1/2 to 1 quart in w/o buying a pan......cheap mans way of more oil...
also the longer filters have more filter media in them.....and im not rocket scientist but more filter media seem good to me.....i cant stand the the one on my V6 accord is like 3/4 smaller than the V6 on my "burn out van"
another way to relate to how a longer filter is better is look at diesels, they got the soot issue in the oil therefor they have huge filters, some even use a bypass filter (it can be used on our cars to just its alot smaller).... a bypass filter is amazing it really and i mean really filters...there is rigs with 100,000 + miles on no oil change, the only "oil change" is to replace what the bypass filter holds, oil does not wear out, it gets dirty, thats why it needs to be chaged
here is a link on bypass filters, its really worth looking at no matter what

there is a truck on there with 1,000,000 miles on one oil chage.....and no this stuff aint fake trust me LOL

But, you seem to be serious.
Think about it - where is oil more likely to "sit" - where it falls down waiting to be picked up by the oil pump, or where it is being forced to move by pressure?

What "I know" about bigger oil pans is that with more oil your motor will run better due to the oil being cooler. Bigger filter more filtering. Now back to the more oil in the bigger pan. I was thinking that more oil due to the bigger filter would be cool, but then again what about the bigger filter being closer to the exhaust? Might offset it. If you had c coated headers then it would keep the filter cooler right. Just thought kicking.

Re: Watch out for K&N oil filters
if i get off my butt and install my headers (i have put 3 sets on 3rd gens so far and yet to on mine) im going to wrap them (prevent heat soak under the hood) and put a wrap around my starter (save it from heat) .......your right about the filter being closer (i think i would have to crawl under)
a good friend of mine has a 302 in a pinto and his filter is so close to the exhaust we think thats why his oil psi get so low once up to temp, that oil is getting to hot, he is looking to get a remote filter to solve his problem
IDK with stock manifolds (only stock part of my exhaust) i still run atleast 30psi at idle with the engine up to temp and all, my motor has the factory oil pump and 148k on the clock

Re: Watch out for K&N oil filters
bigger filter more filtering area, plus more oil. the smaller filter makes no sense to me. i would say it clogs up faster, holds less oil. how does oil just sit in the filter when thier is pressure going through it. the more oil the better lubrication and the less likely your oil is going to break down, because the oil return cycle takes longer. now for drag racing, id actually take a quart out, less oil flings onto the crankshaft coutnerweights and journals therefore increasing crankshaft speed. but smaller filter makes no sense, and thier is nothing that could be said to change my opinion on that. its like saying one filter is better than two.

Re: Watch out for K&N oil filters
ya I was so close to upgrading my whole exhaust system. When it came down to it I had to choose to finish my interior first. Its taken me 3 years to get the money to do that. I got a nice kenwood, All polk momo speakers with 10" subs. An alpine amp, Weather striping ect.
[quote=UnderCover89TBI;4114443]
your right about taking a quart out, But to get the same effect, a good windage tray would work, also keeping the oil temps down with the right amount of oil.

Oh and to the OP, I've used the 2002's and 3002's before with no problem many times, I'm thinking you might have got the wrong filter in the box or maybe they screwed up at the factory and mislabed the filters AND put them in the wrong boxes.. who knows, stranger things have happened..

Re: Watch out for K&N oil filters
Worn bearings. Time for a rebuild time before you spin a bearing. Very slight chance of a sensor going bad but not likely.
How many miles on your motor & what motor do you have?

Re: Watch out for K&N oil filters
My oil pressure got down to zero one time in my old 87 T/A.That was the last time that engine turned over.Looked up one day in my camaro and it said zero driving down the road.As I thought it was just the sender.Our gauges are notoriously inaccurate especially at their age they`re prolly getting worse.I dont think you'd be driving around very much if your engine was seeing actual ZERO oil pressure,even occasionally.I Could be wrong.If its not the sender or gauge you `re prolly in for a rebuild.

Re: Watch out for K&N oil filters
Above the oil filter. How does it sound? Any knocking noises? Is the valve train really loud? Any ticking sounds? If it was really going to 0 while crusing it's amazing it still runs, it should have seized. You may get lucky.. If you have a mechanical gauge hook it up to verify the actual oil pressure. If not just get a new sending unit and replace it and see what happens, they arn't that expensive. You may want to pick up a oil pressure switch socket while you're at it if you don't have one, it makes it a lot easier.

Re: Watch out for K&N oil filters
Why such THIN weight oil?? You live in the Antarctic or something?
You really should run a slightly thicker oil.....I'd change my oil again tomorrow, if I were you. Seriously.
I run Castrol conventional 20W50, which some think it too thick (but it is always warm around here) and am pushing 190,000 miles with no obvious loss of Hp...Just ask my 285 rear tires!

Re: Watch out for K&N oil filters
Why such THIN weight oil?? You live in the Antarctic or something?
You really should run a slightly thicker oil.....I'd change my oil again tomorrow, if I were you. Seriously.
I run Castrol conventional 20W50, which some think it too thick (but it is always warm around here) and am pushing 190,000 miles with no obvious loss of Hp...Just ask my 285 rear tires!

Re: Watch out for K&N oil filters
most small blocks have the sender right by the distributer. if its around 50 deg where u live id run 20w50. with the miles on that engine, u would be fine. i run it in all of my vehicles including my dirt bike, my bobber, 5.2 jeep, gmc 1500 and the camaro with no problems. all have good oil pressure again.

Re: Watch out for K&N oil filters
He's probably following the recommendation from his owners manual. With that kind of mileage some 10w40 would be a good place to start for most climates.... If he's seriously driving around with it at 0 psi on the gauge I'd guess he has a bad sending unit....hopefully.
Above the oil filter. How does it sound? Any knocking noises? Is the valve train really loud? Any ticking sounds? If it was really going to 0 while crusing it's amazing it still runs, it should have seized. You may get lucky.. If you have a mechanical gauge hook it up to verify the actual oil pressure. If not just get a new sending unit and replace it and see what happens, they arn't that expensive. You may want to pick up a oil pressure switch socket while you're at it if you don't have one, it makes it a lot easier.

Re: Watch out for K&N oil filters
yea pretty much. exp, 5W30 is 5 weight winter and 30 weight summer. most oils are multi viscosity. 20w50 is the same deal but 20 weight winter and 50 weight summer. much thicker oil then 5w30. wich increases pressure and supports worn components better

Re: Watch out for K&N oil filters
Anyway take what that guy said above and ignore it. Multiviscosity weights work like this 5w30, in the winter (cold temps) it will flow like a single viscosity 5 weight oil (that's what the W stands for after the 5, winter), at 100°C/212°F it will flow like a 30 weight oil.
Thicker oil will raise oil pressure in a worn out engine and extend its life in some cases. It's also good for hiding things like rod knocks when selling a car. It doesn't fix the problem.

Re: Watch out for K&N oil filters
I hope your not serious......
90W is good for the rear end, but WAY too thick for an engine.
Higher thickness is good for 2 things...Higher mileage & hot weather. Oil thins out as it heats up. So if it starts off a little thicker, it won't get quite as thin at operating temperature.

Yes, higher the weight the better, I run straight 90w gear oil.

i said it backwards, but other then that its true. but do not listen to a guy running gear oil.

Re: Watch out for K&N oil filters
Just bought one of these oil filters part #2002 I think.Go to put it on and it will not screw on.measured the hole and it was lik a 1/16 too small.Took it back and had the guys at autozone double check the part # and cross reference it to all the other filters,mainly the ac delco 454 I`ve usually used and the part number was correct according to theire computers.Checked some other brands and they appeared to have larger hole at a glance.The 454 delco screwed right on.Sorry if I missed a post like this before just thought I`d share.pretty weird.
