Whatever the cause of the "car dying' it was 'not' the topic filter. Topic Boss looks good, including but not limited to the louvers. If the owner is "really interested" in finding out the cause of the failure, it's going to take more than visual inspection of the filter.

@@wilmaharvey4216 I wouldn’t use the trucking industry as being the longevity or Saftey leader. Keep in mind that class 8 tractors didn’t have front brakes till 1976.

And I’ve had 10+ filters fail over the last 15 years. The engine this filter was on had a bad rebuild and is obviously bad luck, less than 100,000 miles and heading to a second rebuild. Hopefully he finds a different rebuilder.
I've seen blue silicone on engine oil pump screens over the years from a little to a bunch, to the point where pump screen is almost fully blocked off. Got to prep surfaces on both sides and use silicone sparingly
I would pretty much rule out the oil and oil filter ! and blame sloppy sealing and blue silicon ! I personally use permatex ultra grey sparingly without issue ! Sad that had happened ! 😢
Enough silicon gasket maker in the oil pickup could have caused the problem. Silicon shouldn't pass the oil pump and filter and plug an oil passage. I suggest your suspicion of an overheat event is probably correct.

The owner was running the WRONG OIL! Modern engine oil like the Valvoline MaxLife he was using doesnt contain the high enough Zinc, or Phosphorus that older engines require. Also back the. Methylethyl lead was in gasoline because it also lubricated the engine.. he should have been using a Classic Car oil with Higher Zinc.
Patt you are correct a lot people don't know that I myself found out the hard way diesel oil is just as good at half the price 5 40 or 15 40 shell makes a great one T5 and T6
I think his choice of oil filter is the best, however he was using the wrong type oil, Valvoline is also one of the best oils, however since his engine had such a low amount of miles he should have been using a non high mileage oil from Valvoline with the recommended weight oil for that particular engine. His engine could of also been rebuilt fairly easy with that few of miles
I'd like to point out that Valvoline (especially the maxlife variety) turns rather dark after a few heat cycles compared to other brands of oil - even in a clean, well tuned engine.
Great analysis, Pete. See, all those additives don't do squat. Just change oil frequently. Car is almost 60yrs old. Who knows what unleaded gas did to it. I wonder if he will rebuild engine? I'm curious WHERE that gasket came from? 👍🇺🇸
Its weird that blue silicone is in the oil. Usually orange or red is high temp. Blue is usually used on the water/coolant side. How did the oil smell? Maybe burnt smell?
Higher detergent oil will get darker faster because there doing a better job keeping your engine clean. Before synthetic oils I used Castro oil and it always got darker faster than the Quaker State I used before switching to Castro oil. Info for you. Dark fairly new oil usually means it’s cleaning you engine more.

@@WhipCityWrencher Shame. Typical for these crazy intervals. I'd rather run The pure One and stay around 5-7K depending on how Blackstone reports come back. Cleaner oil is better oil. And we run filter mags also.
Car's from 1960's and 1970's ran on 20W-50 and 15W-40 Engine Oils not 10W-30. Older car's usually change engine oil every 3 months or 5,000 Kilometres. 10 months oil change is bit too long for older car even if it not driven much. Engines that are re-built usually run on Royal Purple, Redline, Lucas or LiquiMoli over general brands. It could ne that 10w-30 may have caused damaged to engines that are ment to run on 20W-50 or 15W-40 ?
Just use a real gasket.

Good morning. Cool video. I have used WIX and now using Purolator Boss. Great filter for sure. USA made. I hope you have a good Memorial Day. Looking forward to your next video.
The biggest question I have is if the engine was rebuilt 10,000 miles ago , why the hell was he using high mileage oil and Lucas ? High mileage oil has extra seal conditioners and wear additives that a newly rebuilt engine would/should not need. The Lucas is a “band aid” product that helps higher mileage senior engines hang on for a few more years .

Hi whip city wrencher. I have seen a lot of you videos lately. I work for an independent testing facility. I am in the petroleum and oil related products side of the business. My company has done testing for other companies such as Road and Track, Consumer Reports, Field and Stream, Car and Driver etc. I have been doing this for about twenty eight years now. I have tested the Purolator Boss oil filters numerous times since it was introduced to the general public. The Boss is a very well constructed oil filter. That is it's best gualities though. The filters downfall is it's filtering media. As tested the filter is 99% efficient at 40 microns and 50% efficient at 20 microns. The worst this filter has ever tested is at 46 microns. Definitely nothing to bragg about on Purolator's part. Thus the reason Purolator has never posted the micron rating on the boss box, label or filter itself. This may have changed since I have not retested this particular filter in quite some time. No oil filters have a consistent micron rating. Because the filter media whether synthetic, synthetic blend or cellulose is not consistent. Usually dense and porous places through-out. Never trust an auto part stores web site for this information. They are in business to push the products that they sell. So they tend to embellish on their products performance and longevity. Auto part stores do this because most work off of a commission type system. Personally I have never used a Boss oil filter and never will. Mostly due to it's low performance with high micron ratings. So Boss lovers beware. Not as great of an oil filter as most think. There are better quality filters on the market at the same price or for a lower price. Mann and Hummel has really dropped the ball with all the oil filters that they manufacture. I will say from what I have seen the oil filters that are manufactured in China are some-what beter than the ones manufactured in Mexico. China made oil filters use to be of poor guality, but China has really stepped up their QC department in the last few years. With all said above I hold nothing against you, your channel or the great job you do in critique of oil filters. Keep up the good work. I will stay tuned from time to time.
Hi Kelly, If I can't find the specs. on a filter I'll use the ones off a seller's website and mention it in the video, the viewer can decide whether or not to trust it. As for Boss micron rating here it is on their website, scroll down to the bottom of the page. 99%at 25 microns. Thanks, www.purolatornow.com/en/products/oil-filters/purolator-boss.html
Recent tests on other RUclips channels demonstrate the quality on the Purolator Boss and always stand in the top 3. I would never ever put any filter made in China.
That owner has had some bad luck. The FE series, “330, 352, 360, 390, 361 industrial, and 391 industrial” as much as I prefer about any other engine, was typically good for 100,000 miles minimum as long as they were maintained. Having been rebuilt and waiting for a second rebuild with under 40,000 miles… I would ask the owner if he was racing that car regularly and ask if he remembers who rebuilt it so he doesn’t go back to that rebuilder. Silicone kills.
Nice video as always! Filter looks nice. If I had to guess, based on how clean and glitter free this filter is, I'd say the oil pump or something driving the oil pump likely completely failed. If there was any oil flow through the filter while something like a bearing was failing, I don't see how it would be possible for the filter to be totally glitter free. Generally, if something internal is wearing excessively, glitter inside the filter will be one of your earliest warnings before the symptoms start.

Just use a real gasket.
