Now I know why it's so expensive to get machine work done. It's truely an art.

[@anthonyattaway3437]

Yes lord putin you should have some ladas rebuilt

[@eldanel19891]

It's alot of work

[@hekterr6677]

Quality is economy..OHIO=only handle it once!

[@myboy051]

I’m a automotive tech of almost 19 years. I’ve sent many heads and some blocks to all different machine shops. Straight truth, you do Top Notch work. By far the top 3 I’ve ever seen if not the best. I never had a chance to have your work in my hands but I can tell you do great work. I truly appreciate it, Im kind of OCD about all my work. Lol I’m such a torque nazi on certain things. Not brackets and stuff like that. I even torque valve covers and every spark plug that I do. My general manager has mint condition 97 BMW 540i that he loves. He had the valve covers done countless times due to oil leaking. About 6-7 years ago I did them and they are still dry as a bone. About 3-4 months ago I had to do his water pump. He came into the shop to see how it was going. He then asked me what did I do to keep the valve covers from leaking after a year or two. I told him, more then likely cause I torqued the valve cover to spec. Lol he instantly called the whole shop to a meeting and said I want all valve covers torqued for now on. It’s simple things like that makes a big difference. And it only takes 5 or so minutes more.

[@xnggg277]

Hi I'm going to change all the valve guide, valve spring and new valve seat on my bike. My question is is it necessary to change all intake and exhaust valve aswell? Can't i just reuse the titanium exhaust valve after spec the condition of the valve?

[@B17714]

It’s amazing how small of a pit caused the vacuum to fail. Great video

[@TexasGTO]

No lie but one human hair in the valve seat and you'll have a valve that doesn't seal anymore. It's that important to be accurate.

[@theccwdad]

Never had a machine shop go to this level of cleaning. Great work man. I wish everyone cared about what they do as much as you

[@trojanyacht2518]

From a 43 year master tech and shop foreman, excellent workmanship and beautiful results! So much more precise and duplicatable vacuum sealing than say old Sioux vibrocentric stone grinding! Many props to you and your father. You're both living the dream!

[@jeanlawson9133]

Yes I agree 😎 I've used the old Sioux setup.... Nice work indeed...

@Donovan Izaiah why don't you take your scam somewhere else buddy. I've already seen this on comments in other people's videos. Nobody cares and it's inappropriate. I doubt Jim's garage appreciates this...

[@traviskinman3459]

Agreed, as an entrepreneur myself running a service company that repairs and maintain alot of different cnc, edm, and other machines. Blueprinting, double checking and cleanliness goes very far and lastly, stay proud of your work!

[@shaneanderson1036]

many moons ago i was taught valve seating / cutting on a Peterson Bench Mill . was so happy to hear that pop at the end when i bounced the valve off the seat . hand trimming and polishing was a skill i also was taught ! love your channel

[@idiotsandwich6727]

Mate with this level of crafmanship you just cant be cocky, you absolutely nailed those valves and heads.

[@jamesbell7661]

I'm a CNC machinist. and I just started watching these videos of machining the heads and seating the valve stems. and I can't stop binge watching these type of videos. good job guys. it is an art. great job.

[@anthonylehner3643]

It's been many years since I've done much machine work but it's obvious to me you guys do an excellent job in every respect and seem to really care. I witnessed in one of your other videos how important customer service is within your company which is half of any successful business. Love the videos and keep up the awesome work! 👍👍👍

[@bernardlim7123]

I love how you go the extra mile and clean up the edge left by the cutter. I once asked my machinist (now ex) to blend in the machine, but they said it'd be too difficult 🥲 Nice work and keep it up!

[@weldmachine]

Love the way you put your videos together. Plenty of detail and honesty. Especially Good if you post videos on KZbin about Cylinder Heads. Definitely draws in the Negative people. Thanks for posting. All the best. Peter.

[@Ryan_1997]

Bro man... I would so send my stuff to you for some work. It’s so dam hard to find a shop worth the trust here in my city.

[@1BigDaDo]

Remember sending anything over 70 pounds will cost crazy to ship....

[@11fisherj19]

Started an apprenticeship, everything seemed pretty straight forward until I got to the valve seats. We do a lot of irrigation applications and N series seats cut like ass. Not to mention how hard it is for me to see the top angle start to come in. I really appreciate your content, it’s helped me a ton.

[@JAMSIONLINE]

What valve seat machine are you running? Do you use any coolant/cutting fluid? Can help on really hard seats if you’re fighting chatter

[@davidmacfadyen165]

Very in depth with the cutters and process of creeping up to the intake/out take tunnels. Great work thanks

I'm definitely waiting for this. Love your videos. I have learned quite a lot in the last month watching and listening to your videos.

That vacuum pop is so satisfying! brilliant footage. Rarely see any footage like this here in the UK.

[@micahharman1493]

When I need my Subaru heads done this is the shop I will have do it. Fantastic work

[@sreaedhar]

Very professional. The valves did not require match lapping as the cutting in the machine itself produced a good sealing, which was cross checked by the vaccum pressure.

[@КонстантинМнацаканов-н7х]

Nice head work. Haven't done anything like this since HS shop class with VICA 75/76. I'm sure you didn't need to take any classes with Pops around but wonder how he got his start. Thanks again, nice work. I have a 97 Land Cruiser that I want to freshen up and want the head gone over like this.

Good thing people have sentimental attachments to those Subi's because the machine work to keep them going it intense. Just getting them sealed up is very specific. Doable but a lot of people mess it up sometimes directly causing another failure.

[@nick4506]

cool but you might wanna get some measuring equipment to check the surface finish of the head. they look nice from a visual inspection but head gasket tolerance for ra is very tight and it's the only way to insure that they will be reliable. i think alsot of people haveing head gascut issues could bennifit from cheaking the surface finish.

[@3m1n3mx31]

Great video brother! after cutting the seats how do you account for the bucket lifters adjustment? wouldn't they be to tight after cutting? Love the attention to detail you put into your work!

[@a70duster]

6:45 Exhaust seat width measure factory tolerance (0.055" - 0.083"). That seat width looks a lot bigger than 0.083". With the final assembly the valve lash is 0.008" intake and 0.010" exhaust. Did the customer use difference shims to set lash? I find that you can "tip" the valves to set the clearance. No more than 0.003" needs to be removed.
