Cutting Open An Oil Filter Reveals Engine Damage Starting!! 

I do HD marine diesels since 1960. Racing engines for almost as long. I cut open the filters every time. I also test the oil once a year. That filter was plugged. The spring valve is for filters like this. The flow can never cut off. It's better to run unfiltered oil than no oil at all, or a flow that's too low. Bearings are wearing uneven. My guess the rod, crank alignment to the cylinder is off. I found many engines that are mass produced have faults. Like the cylinder not square with the rod & crank, cam and crank not parallel, etc. Factory tolerances are wide based on their warranty costs. I think car companies only concern is having the engine run thru the warranty period without failing. A good engine machine shop will catch and fix all the errors, but it costs.

Hello Kenny, I hope you received my package. I sent it to your work. I sent you a tq wrench, bore scope and some other things. It was the only address that I could find so that is where I sent it. Thanks always.

Oil, filters, and grease, are the primary preventive maintenance any vehicle or equipment. When will people learn ? Great video !

Always good to hear from you young man. Pleasure to watch.

Kenny you do an awesome job of explaining what wrong an also what to do to fix the problem keep up the good work

I do HVAC and I have came across heating oil filters that were not charged in god knows how long they are so bad I had to pry it out with a screwdriver but some how the oil still got to the burner nozzle and still worked but that doesn't mean don't change it just because it still works you are damaging your oil pump and burner some people just don't get it

I thought Jeeps came with engine damage from the factory?

Hey, Kenny, I loved your gentlemanly slap down of the "expert". I've lived long enough to know what I don't know and a lot of what I do know is from mistakes (just don't involve my wife because she has a long list of my "learning experiences"). As someone with two degrees who now happily works in the trades i can tell you that I have zero respect for the "holier than thou" grubsmorglers who think an ability to read and quote a technical manual qualifies them to function in the real world. It comes down to trust, Kenny. I'd rather take your "I don't know" over some arrogant smarfwingler's techno babble. And I sure as heck know who I'd prefer as a neighbour. Keep on busting knuckles and just be the natural teacher you are. Cheers from Canada. p.s. In case you're wondering, with my old guy lack of tolerance for the grossenkuntz of this world, I make up words for people I don't like that sound nasty but will not show up on RU-vid's filters. Try it - I'll bet you've wanted to call an idiot customer a "sminkfest" or a "yorbflub" a few times.

That looks like the oil in my uncle's car. He used to change the oil filter and reuse the same oil. Real smart he was.

One of my favourite sayings. I thought I knew more when I was twenty than I do now.

Thanks 👍Great idea. Next time i do my oil im going to cut open the filter "just for a look"

Take a magnet to the sludge to see if there is metal in it. Also, I believe the spring is meant to keep a tight internal seal so oil doesn't go around the filter.

That is what that is for you are correct and whoever said your wrong should shut up.

Great video Kenny!!! Thank you

In the old days all car manufacturers had a overload valve in the filter base, in modern times some don't have this and use the filter itself as pressure relief The spring does a double or triple duty as you can fit different height elements and it takes up the slack (really cheap ones look normal on the outside but are a lot shorter on the inside) and also covers material expansion with heat and plastic element and as a last resort bypass, have to be very bad for that to happen).

The expert probably would say that's just metal from the filter getting broken in 😅😂

Correct explanation of by pass value spring on bottom. Media filter gets clogged, spring goes into action to by pass clog to continue oil flow. Fellow RU-vidr Whip City from Chicago just explained this last week in a video

Good analysis.

You are correct the spring is a oil by pass

An oil sample to a lab will tell you a lot more than a cut open filter. Send a sample off at minimum annually. You’ll know before you see anything in the filter. For daily drivers more than race cars.

Smart video for the average daily driver diy person looking for a quick peak into his/her engine! As someone else already stated, a yearly oil lab analyst would be best!

If it's stuck in the filter, it is also in the micro screes of your oil control solenoids, and other places too....

Anyone else remember the days, when it used to be change the oil every 3000 miles, and filter every second oil change?

Some oils advertise on the jug that it can be used for 20k miles or 1 year. Not me!

To think my first 2 trucks had no media air filters,but oil bath air cleaners full of oil and what mess to even adjust carb..

Hi i found 2 small silver metal is that means something bad??

Durham, had any vehicles in that have met the can opener bridge? Or just you doing a drive through of the bridge itself. Yes the bottom spring is there to keep the element pressed up to the base, but in the middle is the bypass valve, and up top the rubber is the non return valve on the inlet. Using a different filter than the original is fine, provided it is the correct seal diameter and correct thread. You also do not want to downgrade, so longer or fatter is usable, and if you do not have a spec for valves having them is better for cold starts after overnight, where the filter without will drain back down, and thus oil pressure takes a few turns longer of the engine to build up. There are a lot of filters that are otherwise identical in all respects, just the difference being if they have inlet and outlet valves, and there are cross reference charts saying the lowest version is obsolete, and the others that are a fit and suitable replacement. On my VW I used different filters than OE, as the OE does not come with anything other than the bypass, so I used ones that fit, but have both inlet and outlet valves. Z88, the most common filter by me, to Z147 or Z157, both fitting, just one fatter and shorter than the other, but same area of filter material in them. Older cars you find filters are obsolete, but the modern spin on filter that replaces it is worlds better performance wise, or is supplied by the dealership as a replacement, improving filter ability, or improving cold start performance.

Folks don't realize that regular maintenance prevents the biggest of problems on a vehicle. Folks like that won't fair any better with EVs.

I'm ocd on oli changes I hate going over 2 miles

This isn't rocket science. Replace the oil & filter regularly, and you won't have to replace more costly things. Over the years, I've come across various things that people do to loosen up the gunk in old motors right before an oil change. One guy swore by adding a quart of ATF right before the oil change. Now there are additives for that purpose. I wonder if they do anything.

WWK, keep on wrenching 😉☮️👍🤓🤙

You are right kenny the guy is a not so smart guy to be nice about it

Are you related to uncle tony. Love that one

Kenny! A new computer takes a bit to set up and get used to for computer guys too.

Experience.

“Most” oil filters have a bypass valve so if the filter is plugged the bypass open & allows unfiltered oil back into the engine. Some bypass are in the bottom & some (Motorcraft for example) are in the top…which imo is the better if the 2. Fyi the regular Wix filter is one that has no bypass valve.

In my opinion, that filter off of the Jeep, was ~75% plugged?

Frequent oil and filter changes are the best insurance for a long engine life that you can do.

Have had a couple vehicles only had to screw on a new filter every so often. The burning and or leaking took care of the rest.🤣

That wasn't a squirrel...that's a sign of old age creeping in LOL. I'm over 60 and that happens to me to lol. You really should wear gloves when handling old oil like that Jeep filter. That stuff isn't good for you and hands will absorb that stuff quick. I hate gloves myself but i wear them when changing oil.

We don't have squirrels down here. But something shiny out the corner of my eye is enough to have the same effect 😂

How many engines died due to lack of maintenance? I don’t care what the manufacturer recommends.Change your oil every 3000 miles. Also the person who said to check the sludge with a magnet. Genius,the bearing coating is nonferrous.

I have at least one dumb customer in particular that has a newer Malibu. She's always 5 to 7 thousand over on oil changes. EVERYTIME she comes in with $ light on for timing codes. Car is always low on oil. I guess she likes paying $170 everytime for synthetic oil change and scan test 😂😂😂

Why are manufacturers going away from spin on filters?

Yuck , that’s bad oil .

lol somebody doesn't change there oil . the bearings look like it has a nitro's load on it lol

It looks more like detonation there brother

I'm glad I change my oil every 1,200 miles not to get a filter in this shape. Oil drains out as clean as I pour it in....

Its easy to hide behind a key board those people should get a life instead of sitting their parents basement and criticize others
