I’m a machinist but not an automotive engine machinist, I love how you can preset those cutters on that boring head, I’ve seen a lot of your videos, you do great work

[@Motor-City-Mike]

Aren't the boring machines great! When I first opened my shop, after being a toolmaker/machinist for decades I couldn't believe how easy it all was by comparison. Same goes for seat and guide work - the tooling is all pre-sized.

[@mndlessdrwer]

It's so wonderful to see these engines as you breathe into them their second wind. I can only imagine how happy the customer was with how amazing that block turned out after the repairs and refinishing.

[@anthonysantiago1999]

Attention to detail, amazing work. looks like a factory fresh block and you saved an AMC engine.. Rock on Bro!!

[@TheBlairHomestead]

I admire how you work and explain things so fluently. Always amazing work.

[@alwayssearching1882]

As a beginner in all this rebuild stuff I appreciate the quality of work, machinery, and explanation. Great teacher!

[@DIY-V12]

Refreshing to watch such a professionally implemented procedure, including all the gotchas that can trip up the inexperienced. Thanks for taking the time to detail everything so clearly.

[@mikechiodetti4482]

You repaired an engine like I had in my 73 AMC Hornet. It was a very good engine! I wished it had a larger carburetor, and fuel injection would have awakened that engine! Actually I wish I had the car now! A simple engine to work on and gave good performance. You did a very good job, your details of whats needed in each step made it understandable and the engine's owner will get many good miles with it! Thank you!

[@alanschwartz1157]

If you find my comment above, the car the engine was in was a '71 Hornet. It was bright green, so I called it (of course), The Green Hornet. It would really boogie, and it was reliable. I had added stiffer springs, sway bars and coil-over shocks (I found Mustang shocks fit to a T). Boy! It would take a corner with extra wide T/A Radials. I miss that little car much. I sold it to Grandpa who gave it to grandkids, who wrecked it. Damn!

[@aaronfischer7199]

New subscriber to this channel. As a mechanic of over 35 years it is still great to see that all over the world there is still machine shops operating to this high standard of quality. When I was a younger mechanic we always had heads off and blocks out for repair. Now unless it's for high performance or antique restoration. It is either install a second hand engine or scrap the car. How times have changed in the automotive industry here in Australia.

[@benjurqunov]

America is no different. Aside from industrial engines and hotrod enthusiasts, nobody will pay for rebuild engines.

[@davidsnyder2000]

I’ve never seen equipment or the processes involved in reconditioning engine blocks. I have worked at machine shops before, but nothing like this. This video was really informative…thank you for teaching others how stuff gets done🙂

[@MrHonkrock]

Great job. What you do is a novelty and a lost art.👍

[@rickeymitchell8620]

I have been watching your videos for some time now and haven't commented until now. Your attention to detail is excellent! Love the vids and the narration. Simply presented with the how and why's. Keep up the good work. Shout out to your Dad and the great work he did rebuilding the tractor.

[@9traktor]

Wow, what a fine workshop!

[@spdergod]

Thanks for showing the process. Never seen this done, but have had it done on numerous motors. I was shocked that you could bore the Cylinders without oil or some lubricant.

[@good.morning.everyone]

Beautiful. This is just honest tradesman doing the things they have learned to do over years and years of experience. Well done fellas. Keep it up.

[@coolezum]

Nice job, now I understand sleeving and boring 30 over procedure. 👍😊

[@samnoerpel234]

I enjoy watching straight six AMCs getting new life. Super cool

[@kevinfenwick3477]

Your shop is awesome you and your dad are above and beyond great machinist !

[@januarioqueiroz3122]

You bet!😊

[@philgrimsey3637]

I absolutely wish I had ended up doing machining like this. It is incredibly skilled, fascinating and useful work. A skilled trade that promotes recycling before recycling was fashionable. Love it and if you want a 40+ apprentice from the UK, call me 👍

[@martinsteele3259]

Awesome video and great explanation on boring for a sleeve. I have been trying to learn about the sleeve process. All the things I wondered about, you answered! Thank you!

[@philwardle7369]

Lovely work, it's great to see a shop that still works to such a high standard. Rare as rocking horse manure these days in the automotive engine recon business. Watching this particular job also made me think of the ease with which I could recondition my Triumph TR3 and TR4 engines back in the day, as they had wet liners that were a just a breeze to replace.

[@1soupasaurus]

I've always watched those saturday morning car shows. I know how big .030 is, but until you actual see the cutter removing the material, you never realize how much it is.

[@miceinoz1181]

Hooray! You guys are back to decent length videos. I have missed you. What about an update on the progress of the new shop?

[@JAMSIONLINE]

Shop has doors, windows, walls, a floor, and a roof lol. Needs pretty much all the interior stuff finished :p Hopefully soon, I will make a long video on the build process if it ever gets done lol

[@JustMike2791]

@@JAMSIONLINE Never enough time in the day....and nothing ever goes according to plan

[@bobkrieger5956]

I had never seen the block machining process. Thanks for sharing. Great to see the care and precision taken. Gives me confidence should I ever need your service.

[@thelol1759]

Really glad to see a new video from y’all! I know the new shop has been taking a ton of work, but it’s great to have you back!

[@chrislee7817]

Great work, love your optimistic view that there will be gas around when it comes to its next rebuild.

[@billkea7224]

I love watching a master machinist work.

[@Mangsaab1954]

Just a note to compliment you on you teacher's patter. The instruction is succinct and entertaining. You have imparted your machinist's enthusiasm with bells on.

[@rustynutz4493]

100% ! Thoroughly enjoyed the precision machining, I have the 258 1976 Jeep CJ7 IL 6 in need of a rebuild. I wish Your shop was near by

[@bernardgraf7187]

Love watching these videos

[@lyfzgoodgarage826]

I’d love to do this for a living

[@MeganChic]

I love your attention to detail from start to finish and everything in between. I’ve worked with machine shops that would just rush through and could care less.

[@theburnoutbox9736]

I love watching your videos… I’m always learning

[@bryanadcock2541]

Great video! Thank you for the time you take to produce these. 😊

[@rchydrozz751]

In 1976 I bought a new Jeep CJ5 with the 258 I-6. It had a Chevrolet Bowtie stamped on the side of the engine block. Great engine, plenty of power.

[@qno-oj3py]

Good job. I like that you can hear the cutter is doing it's job correct.

[@Bodeesafa]

Great video! Glad you are back!

[@thomaskirkpatrick4031]

That look after the second dropped nut is priceless.

[@chrisjohnson4165]

Great work as usual, great machines, and all kept clean and tidy. Well done!

[@rickjohnson1632]

Good as new . That’s what I’m talking about 👍

[@JDWard-Jeepster]

Had a 258 AMC in a 1973 CJ-5 these engines are anvils......Very Reliable.

[@scottborst5430]

I figured trying to do a bore on a piston was not super easy and people don’t understand when it comes down to 0.010 is a bit easier to remove then 0.040 I didn’t know the piston wall can move so much thank you for explaining that

[@paulmallery6719]

Used to shim to major thrust to centre . Heat in bit causes taper larger at bottom of bore in heavy cuts

[@ziadrafiq7724]

Excellent job

[@dalesworld1308]

Great demonstration. Well explained to a lay person - like me.

[@JohnH20111]

when changing the cutting head, always put the retaining bolts on by hand & tighten them finger tight before cinching them down with a wrench

[@ercost60]

Great video, love your channel!

[@wisconsintractorpullingforum]

Had the same boring bar/mill at one of the shops I worked at. Loved it!!! Especially for lower counterbore repairs.

[@JAMSIONLINE]

It does good on lower counterbores! Got one coming up, I’ve done a video on one before but maybe I’ll film it again!

[@bigpencap]

Great explanation , wish I could send my engine to you guys

[@jimbos3421]

Looks to me that the engine is telling you where the bore's centers should be, in that particular cyls. "happy place"!

[@bigcliffadventures]

Was a great video my first one so I be here again. God bless

[@pauljanssen7594]

As a machinist we would move the bore a little bit when the situation on coming to our shop being a stock engine mainly you have to know how much cylinder thickness you have to work with to be able to move this cylinder bore over to a reasonable bore size and you have to look at the head gasket situation. And always look at the cost of just getting another block.

[@JeffinTD]

I wonder how many miles and what kind of care that engine had seen… Nice job.

[@soundslikebstome]

My 258 snapped the #1 rod near the crank. The rod punched a 2x2 hole in the side of the block and the piston pushed up in the cylinder with the rod hanging from it. It kept running. Opened the hood to see what happened.....the new window in the block made for any easy diagnosis. I JB welded a sheet metal patch over the hole, and the 5 cylinder lasted for nearly 2000 miles afterward. 73 hornet. 130k when she blew.

[@Bunger428]

Love your content and I don't usually comment ....The big elephant in the room here.. Every time I pull down and engine that has been run with no thermostat . This is the what happens when ignorant people remove the thermostat..cold water / cold front bores .. fuel washes the cold bores.

[@wilsonrawlin8547]

Just watch you complete the Cyl Head. Excellent work and customer is getting a great deal for a very reliable quality engine. Well above the quality of a factory engine.

[@ChixWoman]

Good balance between explaining and showing the work. Maybe seeing a little bit more of the setup for machining would be nice. Good job. Cheers from South Africa.

[@tattoosteveneo]

Awesome as always!! Would love to ship y’all my slant and have a real machinist work on it.

[@andrewklahold2880]

That takes skill, my skills are in welding, I work on antique tractors and things I am not done with a 1957 D8 caterpillar but I do have it running after 30 yrs since it was seized from over heating but had to have some machine work done and want to say you do very very awesome work, I don't know if I'm to old at 55 to learn skills like that but would like to give it a try

Hi, I'm a viewer from Indonesia I like how you finish your work, actually I want my motorcycle engine to be repaired in your workshop. but that's not possible, it's just that I like to see the results of your work. keep up the good work and stay motivated

[@6226superhurricane]

1980 and later 258 are known as lightweight 258's as they removed 20lb's of material from the crank and block. the lightweight 258's tend to develop wavy bores and break rings, they can also get pinholes in number one where they're machined for the water pump. it's always better to use a pre 1980 block but the sleeves are a good option to keep a lightweight going because they won't last long if you bore to 60 thou over.

[@barryfields2964]

I would have sleeved all 6 of them.

[@JorgeRodriguez-po7kx]

@@barryfields2964 Me too 👍😏

[@geoffreymills9932]

i have work in auto machine shops on and off for 40 year's i did line boring , motor Assembly w/ test run and balancing . in the area i am in there is no one behind us to take are place and that's sad . who is the maker of your boring surfacing machine [rmc 1600 ok it showed up in your video now i know] thanks and keep up the great work and videos . i wish the blocks that i work on were as clean as your stuff is clean .
