Still the only channel I support financially,granted it’s not much in the big picture,but being a DVET ,on disability and bed bound, it says a lot about how much I enjoy watching his channel, he seems to have a great personality & really knows his stuff, as a ex tech I miss wrenching the smell of race fuel,& the bits of rubber all over your shirts, this channel helps to give me a break from the Monday of being bedridden..keep up the great work !

As an engine builder for 35 plus years of Diesel engines, I have always been a huge fan of the Detroit Diesel International compound #2 aka peanut butter Glad to see you using it as well!

[@crazylarryjr]

The way you had to twist and pull that inner spring around the retainer piece, the inner spring saved him a major rebuild The mains look brand new, very impressive

[@Berm_Blaster]

Some say they're surprised that these engines can make so much power but it's the street driving that breaks stuff. It makes sense to me. The long sustained run time while driving is hard on things whereas a race the engine may run for 3 minutes max from start to finish. 5 hours straight run time is incredible and the fact that there wasn't more severe damage is a true testament to how well your engines are built and designed. Your the man Steve!

[@travispeoples]

Don't forget to update us on the oil analysis, please! Thanks Steve, always enjoy your videos and your passion for taking care of your products and customers.

[@freedomfox8183]

Steve ..just a thought but I'm pretty sure his springs in the viper are breaking because that engines been sitting for 3 ish years well everything was being built wonder if they were under tension the whole time.. you saw what some slight corrosion can do in Bailey's engine when he didn't take care of it

[@stevenmcinnis8105]

The carboard came off and i just started chuckling in amazment to those ports. Beautiful 😮

Well done loved tear down music.. lucky Ned.

[@joevaagen6170]

Steve, dude i LOVE watching your channel. I'm no engineer or engine builder or even rebuilt my own engine but watching your channel has shown me things i enjoy watching like anything mechanical. Keep on keeping on brother. I drive a 95 F250 4x4 with the 5.8l Windsor and would like to get a little more hps out of it. I've got a set of factory heads that I've ported and have a set of gt40 heads that i also ported along with the original lower intake that I also ported and port matched. Im a little scared to install because afraid of fucking something up. I don't have money to replace the engine if need be and don't know what to do.

[@timothymilam732]

Eric's shop is less than two miles from my home, and he's heck of a nice young man. He's worked on my old F250 7.3 several times. Glad to see he's gotten back in the car, because I thought he was taking indefinite break from racing here while back. But I don't keep up with the racing style he does, too much TV drama for my taste.. Not saying them boys don't run hard, just that it's too commercialized for me. Mr. Steve, the way you bend over backwards for your customers, is exactly why your customers come back every time they need something bigger and badder, because you stand behind your work regardless. Plus you tare it down to see what failed, so that you can improve anything that shows to be a weakness in your design, are anyone else's honestly from what I've always seen. So your work is proof of how much it matters that you supply your customers the very best your abilities, and I believe that you even update their engines once you develop improvements.

[@markfullerton7174]

Steve, I love your videos and your engines!! You are a brilliant man. Please hire an editing team for your videos. This is not meant with any disrespect. As an example- we watched you do the math on neds 2000rpm for 5 hours =300 000 times the exhaust valve opened. Then just a few seconds later in the video you are bringing it up again. I understand that the 2 parts may have been hours or even days apart for you, but an editing person or team would keep the video flowing smoothly and make sure all parts have music. Again, I love and am always learning things from you. Thank you!

I remember from another video you did about how many pounds of pressure is on the exhaust valve when it opens so thats really amazing it didn't tear up the engine.

[@jdlandolt5706]

I am wondering what the oil analysis turned up for this engine and what changes might have been made for the front roller Torrington thrust bearing that showed a heating issue? I know you said that the oil had a distinct smell and that oiling issues cause wear in an engine.

[@jeffheins6624]

As hard as he ran during that week, I believe Ned sees the advantages of having spare parts on hand. Good to get a Dewey fix, great customer service

[@jasonH5997]

That retainer had of held on til the last second...insane that piston is perfect.

[@angelmarcano6747]

A true artisan in engineering and in engine building, a master at his craft. If he was to have a title it would be Professor Steve Morris PhD.👍👏👏👏

[@RichardHatch-l9e]

Fun fact number 3. If the manifold top hadn’t blown off he definitely would’ve scattered the engine on another full pass

[@MotorSwapDan]

Bet the hung valve caused the manifold to pop

[@136092195]

As always very nice work Sir

[@dragula3773]

Steve, it occurred to me watching your video, that with the distributor hole in the front canted to the side like a Chrysler, you should design a set of billet Hemi water heads for your SMX block... Would be so cool

[@bobolson1903]

The exhaust gas pressure / flow will help to close the valve with the inner spring keeping the valve stay closed during compression and power stroke. Sort of like the desmo valve system in some older Ducatti bike engines, and some old GP engines to eliminate valve float.

[@darrensamuels1511]

It just goes to show you Steve how good your engines are. 🙏🇦🇺👨‍🏭

[@gordonstarship]

I really liked the music choice @ 33:00 to 35+ That was an experience...

[@riddlemethis01]

Damn they must have had an angel sitting in the back 👍

[@reztiews]

Would be interesting to see Steve pull an old data log from the wagon and do the math on how many times a given valve cycles during one pass

[@ralphhbernstein6798]

8000 RPM/2 4000 RPM/60 == 66.6 Times per Second, 6.5 sec pass == 433 times.

[@alkennedy1124]

I’m loving my freedom piston prod fist shirt , thanks BigAl California oh I dropped on half of my number one cyclinder valve retainer and drove it 100 mile before it let go and pushed a valve thruogh block lolthanks BigAl California

[@bobroberts2371]

Thrust bearing. It looks like the crank side washer is spinning on the crank. The heat on that washer is limited to where the crank contacts the washer. Had the heat come from the roller side of the washer, the entire face would be blue. ( Or at least just on the outer edge since the crank face would absorb the heat. )

[@skeetamacgyver1821]

I was wondering the same thing. Perhaps the shim facing the crank did not have enough preload to engage the bearing assembly and the rotational friction between the crank and the shim caused the heat? I wonder how the thrust bearing is lubricated. If it relies on splash this may not be enough when doing the road driving at low rpm?

[@WineHouse33]

Sad we didn't get to see Steve's wagon in action. He was on crew chief duty...

[@michaelanthony8638]

Hey Steve Im a Ford guy but like your content just want to say if the valve spring broke on exhaust valve side I think there would be a different out come (ie) intake chases the piston down the bore. Cheers Northern Mike

[@compt3ck]

Shows piston torched "Tune up looks really good... that had some kind of tune up issue." I was so confused for a second and was thinking an injector must have been bad or a really bad timing issue on one hole. Then you clarified haha. That valve spring is some sort of miracle to hold on for that long and never even touch the piston. You should see if it can turn water into wine or better yet water into C16 fuel.

[@Fabrice1970]

Great video as always

[@patrickmcnulty6050]

You are awesome love the content keep it coming 👍🏻👍🏻

[@djbigdaff122]

Fun fact no.3 your engines are absolutely insane

[@RB205AIKIMAN]

Love the videos especially the super technical videos especially on cutting valve seats and cutting fire ring groves in the block and head assemblies. Question can your seal a head to a block using a conical seal not unlike a poppet valve seat per cylinder?

[@jeffreylynch3203]

So, being in the business for over 50 years I have to sympathize when it comes to bad parts, but just a few years ago I was building a big block for a customer. Having built so many engines complacency or attention to detail almost cost me a bunch. While assembling the heads everything was going just fine when something caught my eye. On one valve the distance between the keepers looked excessive. I looked at the other valves and some were what I would consider normal, some had a bit of space, and this one had a bunch. So I began looking at each situation and found that the bubble packs of locks were mixed; 5/16ths and 11/32nds. I had to stop and have a cup of coffee. That really could have been catastrophic. Parts have been an issue for all of us, but something like that could slip by so easily. And in the event that the engine does grenade, a good guy like you needs to evaluate the situation to a conclusion and do the right thing, not go on the defensive. Some of us still care. Good job.

[@jameslo3]

Ned is running an MM transmission like Cleetus…both have an issue with the thrust? Interesting.

[@ProblemChild-xk7ix]

Very cool it scares me everytime I listen to your intro and you say caution you might learn something my brain can't comprehend everything that I have learned watching your videos I'm not a computer stop before you blow my mind up lol now let's get down to business the reason why the valve never dropped down in the piston is because Ned has such positive attitude he's like the coolest get er done he goes with the flow

[@sryghdugan]

Lash cap saved the day

[@MartinRodriguez-yr4gf]

puts a smile on my face when I see a hammer handle being used to install pistons. Not like we have all of these new sophisicated tools these days

[@greglindholm9870]

It would be logical to think that perhaps excess fuel in the oil lowered the flash point. That coupled with the long run time on the drive caused thermal breakdown and a drop in SUS viscosity. I would be quite interested in the oil analysis. Excellent content as always.
