Always enjoy your history lessons! So much knowledge to share. Thank you. I've been reading your articles since the 70's and they're always interesting.
Love your videos.Just need a 2 camera set up for close ups.You could just have stills to highlight areas for simplicity and lack of expense.Keep up the good work.
Good video. Technically the piston oil jets got their start on the Twin Cam though. I'm working on adding them to my 106" Evo because I'm on my 3rd piston failure from piston heat and scuffing.
Yes, it took over 60 years but Harley Davidson finally caught on. This calls for a round of applause. I also heard their engines are making upward of 80 horsepower now.
I love these videos, very informative. Does anyone know if the oil goes past the cooling system prior to getting jetted under the piston? I’ve always thought the oil from a warmed up engine sump would be like using hot tea to soothe sunburn?
The pistons and heads are the hottest part of an engine, so the oil itself is going to be cooler. Of course a dedicated oil cooler helps but the oil gets "cooled" by circulating again through the engine.
Even if the oil is only 5-10 degrees cooler, it will help control heat, keeping it from reaching that point of no return where we end up with a thermal runaway situation that will certainly lead to what I call (R.U.D) Rapid Un-commanded Disassembly…
It says on internet 2011 3.5 EcoBoost uses piston cooling... 2011 f150 EcoBoost 114,000 miles burns 0 oil....although some people say 2018 f150 EcoBoost 5.0 liter engine burns oil.... New truck burns oil wtf, were engineers ,thinking..
Diesels had piston cooling thru the connecting rods. At the wrist pin end of the rod was a spray nozzle that directed oil from the crank thru the rod to the under side of the piston.
[These] videos are a joy to behold and be a part of. One of the few things on the Internet that are. Thanks so much!

I could watch Mr. Cameron for hours on end. So informative and well done

great video ole tom sifton was the man back in the day still today they use his knowledge
Great Mr Cameroon
Thanks tom sir....and kevin sir in first place....to let us know about this great invention
Always, always great . Many thanks Mr. Cameron. 👍👍👍
Can you do a tear down of a Sportster engine next and why it's been relevant for 40 (the Evo motor) years in the Harley lineup?
My old 72 Harley Sportster had sifton lifters and guides they were aftermarket they have a oil Groove Cuts around them
i love your this chanel.pure knowledge
Awesome, thanks to the info!!

This technology must have disadvantages right? Can you tell me what are those? Thank you in advance

@@hakrsakr valve springs run extremely hot as well

Rapid
Un-commanded
Disassembly…
My 2002 Honda shadow VT750 has piston cooling oil jets.
Oil is what really cools an engine.

My old motor home diesel has them - it works hard lugging her about

More focus should have been given to engine parts rather than this Grandpa!!🙄😂😂😂🙌
That is a lousy disparaging remark. Go back to sucking your thumb
