Engine Shops Are CLUELESS About Titanium Valves!

I can't believe that this kinda stuff goes over the heads of 90% of the population, plebians and pro-fresh-een-als included! Titanium valves are indeed serviceable and with some intentional and well planned processes are easily machined with regular equipment. We're going to talk about a very mundane task, in my own Josh style. Hang on tight!

This is the engine only version of This Old Tony

[@bigboreracing356]

Lol👍🏻

[@outtodoubt]

First time watching…thought the same thing 2 dad jokes in!

[@christophermarchand320]

EXACTLY!!!!!!

[@Super-Dave-Outdoors]

Appreciate all the detail, explanation of the work, sarcasm and satire! As far as what to work on next I dont know but i would like to know about how port surface finish affects airflow in a port!

[@GrandPitoVic]

I enjoy your videos. And I enjoy the sarcastic humor. Someone will talk a lot of junk no matter what you do. I make videos for my grandkids and I get a lot of bad comments as well. I'm not making videos for them. I am making them for my grandkids. The videos will always be there. But I've gotten way more positive comments and some are very good and some are very touching. I get way more on TicToc lol.

[@EngineRehab]

I’ve been in the public eye sharing stuff online for over ten years. It’s always been the same. Thanks for watching!!

[@silverado123]

Thanks josh for taking the extra time to show those of us that are curious how you do these processes. Also love your humor. Makes me laugh

[@EngineRehab]

Glad you enjoyed it!

[@MJPilote]

It is a real pleasure to watch your work, it really show’s you love what you are doing.

[@EngineRehab]

Thank you! It’s a very complicated situationship

[@rolandtamaccio3285]

Swirl polish hides the machine marks . Ohhh ,,, !

[@Baard2000]

@14:00 Clean your machines... Well....I ckean them from any debris fouling them. I never use air pressure but a vacuum cleaner. Debris flies around to everywhere when air hose is used. Always use loads of way-oil when working with scraped beds. When using water based coolant on a lathe always move the ways afterwards so many times no water comes away from beteween the bed ways but only bed way oil. Oh...and the Tobin Arp VGS2000 or Sunnen seat and guide machine ....I always keep the bed on which the head floats on air extremely degreased so little chips and debris are blown away by the floating head. In that way debris wont come between head and bed. The head floats about 0.04mm height when air pressure is apllied ....so if the bed or underside of head is greasy/oily.....chips wont be blown away. Also use a vacuum cleaner when porting and polishing ports ...the debris will float anywhere in your shop. When porting a lot.....make sure machines in your shop are changed to indirect forced cooling of electrical circuits instead of direct forced cooling. Seen many shops having problems with electrical issues by shortcuts caused by ultra fine metal debris...... Recently shop nearby almost smoked out an amplifier by such debris accumulated on circuit board.

[@drewnicest4319]

I enjoyed the video even though I'll never be grinding any valves lol

[@jacquespoirier9071]

nice finishing touch on these valves.

[@johnkoury1116]

Great video my friend. I have the same machine that is on the table behind you. really awesome stuff.

[@EngineRehab]

I love it!

[@lancasterjim2441]

Time and attention to detail on a valve job is almost non existent. Keep it up brother great channel.

[@rickyfulks889]

Great video, nice work indeed

[@KingEdwardA]

I love how my first time watching a video i was welcomed back like a drug addict. Subbed

[@EngineRehab]

Hahahahaha. You win today. Now come try out this new stuff I got.

[@greatestevar]

I am so glad that using my drill as a lathe is common practice

[@Gregorybridgewater]

There are even higher precision ER32 collets and caps if a guy needed something more true than the .00015" guarantee that Josh is using here. Collets are very precise versus the old finger chuck that ive seen on some of these machines.

[@sinfulcoin]

Any chance you can post the brand of the flycutter you use in the BP? Been trying to catch a glimpse and get one like it for some time now.

[@jeremiahchamberlin4499]

Quite informative.

[@johncarlson2255]

Do you know if you spray penetrating oil on the emery cloth it will polish any metal beautifully without scratches

[@desposyy]

We don't see the machine shop as our enemy, we just can't afford to pay you

[@buzz2jz]

I just Subbed,,, came over from Jim’s Automotive, apparently you lent him a tool to help out with a customers snapped bolt in a Gen3 LS, but you ain’t got a multi-coloured Afro or a big red nose… what gives? 😂

[@mooreevair]

Bag of pickles. 😂

[@bcbloc02]

Every now and then I chuck up a valve and it’s visibly way out. So I chuck it again thinking no way then it’s still out. Grab the indicator and check the stem and 9 times out of 10 it really is that out and not my machine. I get fussy if I am more than .0005” out but it seems a lot of valve factories are satisfied with .003”

[@EngineRehab]

Some are better than others. And yeah I agree. Most the manufacturers aren’t checking their runout.

[@RussellCompton-fh3gr]

about how long would un-coated TI vavles last in a street-strip engine with about 120/140 lbs seat pressure max lift high 5s to low 6s

[@mikebougher3731]

Are you running oil on the valve grinder or is it coolant?

[@EngineRehab]

It is oil

[@GrandPitoVic]

Roflmfao!!!! You are very funny brother!!!

[@chimpfoos65]

What Does it cost for the coating to be reapplied do you mind saying

[@EngineRehab]

It’s less than $30 a pop if i remember correctly

[@georgedreisch2662]

Have found a good response to individuals alleging “arrogance”. Well, I used to be conceded, but, now I’m perfect… Any recommendations as to re-coating providers / services? 100% necessary? Depending on intended use?

[@EngineRehab]

Calico offers crn coating!

[@lunarbacon9750]

Love the explanation of how and why you do things and why you shouldn’t do certain things. Also the quality of the vids are excellent! Do you go to bed and think… “man I make valves look good!?”

[@EngineRehab]

I actually don’t sleep for several days, film a video, then once the dopamine hit wears off I get a good 3-4 hours in and repeat.

[@BentonL]

Surface grind a Cummins 5.9 head nothing else what should I have paid....

[@andrewmcmullen4810]

Can you please chamfer the bur on the retaining nut on the grinding wheel please. It’s freaking me out.

[@EngineRehab]

If I did that I’d have nothing to tap on with my drift.

[@mooreevair]

Funny. I saw that and was triggered in a small way as well.

[@scotts439]

your voice is like a laxative. Here's to staying regular!

[@EngineRehab]

I’m not sure how to respond to this. Let’s just hug it out and move on.

[@hershbagelstein545]

So you did Ye’s titanium teeth?

[@EngineRehab]

Yeee

[@buildaboiworkshop]

Hai

[@02f4irider]

Crazy to think people use toothpaste to lap valves when it typically has abrasives in it as well. We looked at toothpaste under a microscope when i was in high school. Pretty crazy whats in it.

[@EngineRehab]

Yeah I think the idea is it’s less abrasive than other abrasives. Maybe acts more to polish than remove material.

[@02f4irider]

@@EngineRehab i figured that. To the touch it is definitely not as abrasive. Its just shocking what some things have in them when inspected closely. Loving all the detailed information with your work. Ive been learning a lot with yours and others videos, even if i myself never put it to good use. Lol

[@matthewmoilanen787]

Most machine shops don't do stainless valves as they probably do as much tractir and small engine valve work as auti engine work. Therefor as time is money the accuracy they need is obtained without the need for constant machine ckeaning. Doing valves in your basement as you do afforda you to be as fanatical as u choose with regard to machine cleaning. Put simply it just cost tbe customer money they don't want to pay for u to constantly clean your machine. If specialty work needs to be done then the customer should be willing to spend more and search for a more specialty shop. It's all a matter of economics. I am surprised with u being as critical as u are if others wgy u were using the incorrect grinding wheel for Titanium. I'm also a bit suspect if putting a tight tolerance "Nascar" valve in a tumbler for any reason what so ever. And using a cordless drill with a Scotch Brite pad to clean a valve with an exceptionally thin coating seems a bit ill advised. It seems a bit like patting your own back for the pretty shine.

[@EngineRehab]

Hey everyone! We found who doesn’t maintain their equipment!

[@greatestevar]

That's a lot of typing to declare publicly that you are a fuckwit (Matthew)

[@ellieprice363]

Sorry, can’t stand the voice but learn a lot from watching the operations. Works for me to turn on CC and turn off the audio.

[@EngineRehab]

I’m glad you can enjoy me in silence. Much love soul brother.

[@greatestevar]

I don't know if he drinks a lot, or is jewish; But yeah the voice gets irritating. All the hocking 😂

[@Joshsucks69]

Bet you don’t even know how to work on a 1g 4g63 head 🤷😘

[@EngineRehab]

I see you pookie
