Sometimes it's the cool tools (spring compressor) and sometimes it's using something I hadn't considered (drill press for valve cleanup). Always a joy to watch.

エンジンオーバーホール作業の、基本的な作業。！！！スバルエンジンに限らず、自動車工学的に大変勉強になる映像だと思います。バルブの摺り合わせ作業、バルブの磨き方！！！テープを巻いてバルブの軸に傷つけない様にドリルのチャックに挟む、、、またバルブガイドの交換、バルブの取り扱い（外すと、組み立て）ここまで丁寧な動画を未だかつて見た事がありません。この映像は価値がありますよ！！！自動車の修理関係の方々や、学校の教材としてもとても素晴らしい動画で有ると思います。

Just wondering did you reface the valves and regrind the stem tips ? Also did not show valve seat at least being checked for out of round ? was this done off camera ?

[@jeffwhite9001]

And no stem to guide clearance checking.

[@andybrossdigazz1675]

I think like a market. So clean workshop... 👍

[@PropanePete]

We used to call that job you did a "valve grind" and just a quick question from an ex 1960's era mechanic. You lapped the valves in without re-surfacing them and re-cutting the seats or using a syncro-seater. I assume you used some blue marker and checked the seating width and position on the valve face but didn't video it. Is that the normal procedure theses days. I really enjoy your videos and your workshop is kept surgically clean and neat... love the little doggy too when he/she occasionally pops into the frame...

[@blubug768]

No, its not "normal procedure" to not cut seats, or not face valves, or to bead blast without pulling galley plugs, or slam valves dry through new seals, or hammer seals on with a socket... well maybe it is normal, but I would get fired if I did a job this halfassed.

[@jameshanoomansing1442]

lost for words....perfection

[@artmor79]

Thank You!!! as always super awesome to watch.

[@zoomzabba452]

When bead blasting, how are you keeping the media out of the cam oiling system? We always remove the plugs so that any remaining glass can be washed and blown out.

[@984francis]

I think it's dissolved soda not beads?

[@zoomzabba452]

@@984francis even if it is soda, without removing the plugs, you can't guarantee all non blasting materials have been flushed from the area

Hi, it's safe to wash engine heads and blocks with wáter/glass? good job !

[@charlesdefrancisco5056]

Your shop is quite well equipped..and having machined thousands of cylinder heads..I’m wondering a few things...why would you not glass bead the valves and did I miss you grinding the valve faces and what about reshooting the seats?

Where did you get that beauty of a valve spring compressor tool? Please do tell! Other tools seem barbaric compared to this one. I've made new curse words with the combination of tools I used to remove the keepers and springs. Thank you for a great video as well.

[@josenar145]

Excellent video! I only have one question. Wouldn't it have been more prudent to check for a warped head prior to starting the work on the head instead of at the end of the video? What would have been point of doing all that work if the head was warped? Or did you do one initially and this is just a final check?

[@fredmann8799]

Tolles Video! Vielen dank! Absolutely awesome video! Thanks!

[@stevesisniegas]

good video. What is the blue water that you clean the springs and valves?

[@anitabonghit266]

I love your videos man. I build motorcycle engines and i am very jealous of your set up. I'm confused why checking for flatness was the last thing you do. Being how clean you make everything, i don't see why you would mill the head with the head partially assembled. Besides that i love everything you do and these time lapse videos are my favorite. I wish you much of luck with your career, even though it's easy to see you are doing very well so far

[@rickguyevans]

I agree...I was surprised that it was seemingly checked last...maybe he checked after vapour blasting and showed it lastly to prove straightness?!?

[@VenturiLife]

Hi. Is it worth re-using the valve springs, or replace them?

[@jeffbecker8716]

Question: I did not see you mark any of the valves or springs when you first removed them. Is it not important that they be returned to their original positions?

[@joriskylie6857]

Yes

[@brianr987]

Is lapping the only option for these heads? Can you not replace the valve seats themselves and grind the valves to seat, then follow up with lapping? Hmm, checking for flatness of the head after assembly. Doesn’t make sense to me. I would do that first. I’m sure you have good reasons for the way you do things. I like this channel. Very professional work. Nice shop too.

[@pentlx]

Lapping is much faster and much much less expensive than replacing the valve seats. Why create unnecessary work and expense with no benefit? Also, newly installed valve seats often move slightly in the head when the engine is first run, not enough to affect a stock engine's performance, but for optimum seal the head would be removed and the valves redone after the engine has been through several thermal cycles. So installing new seats unnecessarily would actually be counterproductive in a performance engine.

[@kiddiescripterkiller]

Oven cleaner will take the carbon deposits off the valves and pistons... rinse off cleaner, then polish them with a brass wire wheel.

[@ramnave2818]

Hello , you didn't show it but did you check the valve guides for wear and also straightens of the valves? great work thank you for sharing!

[@kellyspeppers]

Nice video and good work. You had a nice set of heads and valves. Most Subaru heads I have worked on are warped and the exhaust valves pitted badly.

[@razvan4motion]

on the exaust valve there is an DLC coating? If so you don't remove it when you sand the valves on the drill? it is not better to use new valves on the exaust?

[@Svemir.]

Germans have a tool for every thing love it

[@gwot]

i'm pretty sure most countries have a tool for everything as well... nothing special about Germans

[@kiddiescripterkiller]

I have Lisle Valve Keeper Tool where you stuff a rag under valve and push down on the tool (or use a hammer. I never had to use one) and it catches the keepers with a magnet and will install them the same way... way faster than his valve tool. Or you can do it old school with a socket and 2 vice grips on the socket for handles to push on and a magnet and to reinstall set keepers in place put a thick piece of cardboard over it push down with socket.

[@martinda7446]

That valve compressor tool looked really cumbersome and time wasting. Loved watching these videos, the cleanliness is approaching food standards (They should get a food hygiene inspection certificate put up) . Those engines are 'seasoned' and rebuilt with such care and attention they are possibly better than new in many ways.

tres bon travail félicitation et la vidéo de bonne qualité un gros pouce bleu merci

[@seshachary5580]

very nice thank you spotless workshop

[@Ruslan_Subarist]

Excellent when there is such equipment for washing parts. By the way, such a white, limestone scurf on exhaust valves appears when antifreeze gets into the combustion chamber. It is better not to clean the valve mechanically. There is a special metalized coating on the valve plates, it is erased. Therefore, I cleared the exhaust valve chemically. Domestos for example well softens this scurf. True time takes more, because you need to withstand the valve in this part at least 12 hours.

[@AdamBusing]

Good Lesson on how to backyard screw up your heads and valve train. One. Why were each valve, retainers, caps and collects not correctly numbered to each port they came out of? Two. Why we're the heads not checked for cracks? Three. Why were heads not checked to see wether they were warped? (They may look straight, but under a flat edge and using feeler gauges to check and ensure the heads are flat and straight). Four. Same with the valves. Each Valve, Retainer, Caps and Collects will all have their own wear pattern even with a valve grind and also the valve stem. This presentation is actually now being used on college campuses on Engine Building on the do's and do not's. Not even Mike Finnegan from Roadkill is this rough with a build. Congratulations on making college campuses. Not too mention, every step here does not meet Subaru's Internal Workshop or even Pro-Drive's steps. Video shown to four engine builders with 35+ years experience, three of which are Subaru Specialist, all cringed at this le video and they would not even allow an apprentice to practice this sought of behaviour as there is a reason for engine builders to do projects correctly, so one they are guaranteed secondly so it does not blow itself to bits by cutting corners... Gee wiz every motor I have built not using this method but the correct method is still running after 20+ years. Its all nice and dandy to have a clean workshop and tools, but what's the point in that if you do not follow even the factory Subaru Rebuild Methods (JDM)... To content creator thank you for providing an inspirational video, where 10 students followed the build process (5) did it your way, 3 valve train failures within 1000km the other (5) complete the build the Subaru (JDM) Method and not one issue in 5000km on a B4 EJ20R *** And you are German are you not? as am I which is a disgrace too our Engineering that you would intentionally ignore basic standard procedures... Shame on you!

[@franks6135]

Thanks for your comments. This is not a dig at you but can you provide a link to the correct way to do this? I am serious. I am trying to do this on an EJ25 right now. I do like Subi Performance and his efforts to teach us. I however like everyone else think, "A wise man seeks many council" as I read in an excellent 2,000 year old book once.

[@hughmoore810]

Karl F H Elsewhere on here Subi says this is a "small budget project." Which means that customer doesn't have a lot of money. Also to another poster "the guides were in good condition." Perhaps some operations were not shown on video ? Subi didn't reply to many questions & criticisms on here ? English is his 2nd language so perhaps he can't fully express himself in it ? (as in effective argument in English ?) I do notice that he does a lot of Subaru engines & a few that win in competitions. Being in Germany most of his customers are German thus he mostly deals in that language. You don't stay in business long doing shoddy work & his workshop & Subaru special equipment is 1st class PLUS. The equipment he uses would cost a fortune in total & to pay for it needs a steady flow of work. Judging by the amount of engines lined up around the shop Subi is getting it ? They (the College) show the budget build but also someone should look at some of Subi's other builds were he uses all new parts, as in pistons/rings/valves/guides, con rods, bearings, crankshaft (he may use an outside workshop for balancing & machining ?), rebores, honing, bolt tensioning including bolt stretch to spec, larger diameter holding bolts including retapping, head & cylinder top machining (where necessary), tension wrenches, seals & gaskets & tube applied sealant, bucket shims & clearances. Most Subaru's run a turbo so the stress on the engine is high. I'm sure Subi wants his engines to be reliable ? No sense having lots of customers knocking on the door complaining about stuffed engines. Many parts like valve seats, valves are above normal auto standard. If the wear is minimal they can be reused with regard to the use of the vehicle. Engine rebuilds & blue printing mostly involves costs. The higher level of the job means bigger amounts of money to shell out. I think your criticism of Subi is somewhat misguided ? I'm in OZ & a long way from Germany & I don't have or never have owned a Subaru. All I drive is an older 4 cylinder slowish car.

[@franks6135]

@@hughmoore810 I'm with you. Iv'e been following this guy for awhile. He not only know what hes doing but is not lazy by any means. I personally know he checked his valves, examined his valve seat width after lapping with a mic, washed his heads in the parts washer after blasting, and did all the other things in question on the comments. In addition to what everyone asked about, I know he balanced the rotating assembly, checked valve lash, Plasti-gauged all bearings etc. This was not an educational step by step video nor meant to be. Just a so you understand what goes on (but not give away all my secrets) kind of thing. My point to the other guy was this.... Doesnt matter if you saw everything that needed done you should seek advice from many and learn from each one. IF he had showed every step the video would have taken you all day to watch. Trust me he knows what he is doing...

[@hughmoore810]

@@franks6135 Subi uses dial gauges, never seen him use plasti-gauge ? Subi could show more if he wanted too, speed a lot of things up like he does at times. Video taping can take a lot of extra time & time is often money lost. He does a lot of rebuilds & a good reputation is hard won. I'm sure he doesn't get many if any failures ? The basic Subaru engine design is long proven over a long time. There are plenty of quality engine parts available. Put it all together like Subi does & he's on a winner any day of the week.
