seriously why is this video so underrated to the amount of actual knowledge required for basics of rebuild, i mean this 18 minute clip is packing some true stuff

A lot of engines going to be saved because of this video

by far the best break down on KZfaq by far.....Well Done

So much free information.great content

Best video on engines I have seen in a long time

What a champ, this video deserves to be seen with every car owner. Thank you

Great, stuff need more video’s like this, racing 101 series would be epic

First time a hear someone discuss issues knowone bothers discussing or checking. I can add the following : If you build engines own a bore mic and outside mics as it enables you to measure accurately and more importantly ovality which you'll find in alot of mains and bigends. Plastic gauges are better than nothing but not ideal. I wouldn't run bearing clearances as low as 28um but would suggest a min of 40 -45um on an Ave 4cyl. Grinding cranks has its drawbacks as most ground cranks ive measured have upto 20um ovality .I would suggest no more than 5 . So to conclude I would torque everything without bearings inserted to check size and ovality before anything if a new build engine.

More videos like this PLEASE.

i love when herman explain into detail, i went to tuned by him and he explained more things to me then tuning and i really appreciate it all the things he taught me in that dyno session, much love herman

I have acquired a great deal of knowledge. Thanks.

Great episode ! One of the best explanations I have heard to date.

Probably the most educational video I've seen...

Amazing video. Thanks for sharing.

This is my take on information that was given... You cannot always blame the person building the engine. There are many factors to consider. The engineering side of the engine build at times can be a problem and I've been there before, as an example: I built a m50b25 to spec adding about 2 deg of torque to the bolts to hold things properly together and told the customer the piston hights are not all the same(was decked by engineers) The customer said just put it in, i asked about the crank he said they said it's fine don't worry use standard bearings i said okay, i told him the cylinders wasn't honed he said he knows but it's fine so i told the customer there are loads of inconsistencies but he said assemble the engine and i did what was asked. The engine ran good sounded good but didn't last long the worst words (raise the limiter). I asked how much oil did he put in and he said the amount he saw on the net but couldn't say exactly if it was right because some forms say so much and the othe say so much bear in mind its a pop car permanently at high revs and i explicitly said add about a half to a pint more oil and he didn't. Long story short after sitting on the limiter it ran a bearing and i told him it's because of insufficient oil in the sump. So i was indirectly told i build junk but all the other engines i built he beard witness to that are still running well. When it comes to tuning, so many people tuners are quick to blame the person who built the engine and some will not and will check what could be the problem. Many of the vehicle owners are also to be blamed because of that gie nog a bietjie and then something happens then it's ny hy kan mos dink blah blah blah and some tune just for WOT which is dumb in my opinion. I was trained on tuning by a very cool guy humble in all ways and told me some people want to rev high for street cred even though they not making power there. Alot of what was said is true but too many variables to take into consideration before blaming the bra building a beast in his garage.

Extremely talented, i remember my brother spending ours on the dyno by Herman feom the morning trying to get his golf just right. We talking 10 years back and those days our mk1 golf's had baffle sumps on to help to keep oil in the sump and prevent splashing around. Excellent Excellent information.

Very informative. Thank you.

Amazing video!

Well put together information sir. Please do more.

Very informative... Thank you Mr Page

Dies n informative video🔥🔥🔥🔥🔥keeps getting better

Very interesting! Awesome content buddy. Looking forward to more in detail videos in the future. Excellent stuff

Greetings many thanks learned much from this video 🚘🚗🚙⛽️

Good video this

Mr page I must say this video was very informative thank you very much

What about oil starvation on a EJ205 ? Great knowledge my friend you answered my next question is running a little more than max a safer solution? I change my oil every 3k miles plus a filter Change around 1.5k is this gd practice?

The best explanation vid ever.👌💯

The same thing we do with forge subaru who wants to make big power we add a shim to oil pump makes a massive difference like you said.

You very educated you💯

Very informative 👏.. do more of these

Great video. More please

It’s the combustion stroke that pushes the piston down not the crank, why did they show some guy oiling the outer of the bearings shell?that’s a no no. Dry sump is the answer for racers, expensive tho. Excellent video

Great stuff💥

Good info in this one 👏🏽

Great video

Top content!

Great stuff

.. Now I know exactly how , when and why I ran a bearing on my 180i Ballade back in 2012 , damn , Herman doing the lords work ! Very informative video , more like these please and thank you for alles also ! .. #bless

Oil film thickness. Hot engines need more viscosity. Turning up the boost….more load on the oil film….need more viscosity. 10w50 or 10w60 and your engine will last forever

What about oil filters pressure relief valve?

detonation can run your bearings pretty quick too

Greetings sir .i have a Yamaha 2zz ge in my celica.light crank noise started and from taking out the oil pan noticed bearings were going out..i immediately changed the rod bearings without checking the clearance.car has been driving well but im worried because many people talk about clearance.

I'm looking for an oil temp and pressure guage for my E82 125i. Something that won't be too bulky and possibly use something that compliments the interior of the vehicle, do you have any suggestions? 🙏

we are 20 years professional engine parts OEM manufacturer.Our quality is high and stable.

Thank you I got it

Lol for the engine is Nog alryt piston deur dier block geskit

SO DRY SUMP LUB IS BEST LIKE THE V 8 , APP 12 LITRE

All that information for free 😬

"B20 hondas", proceeds to sho 4age 20v blacktop

Just wrong dirt and fractionally excess bearing clearance do not cause bearings to instantly fail those sorts of issues cause bearing's to become worn prematurely. But tuning done in the wrong way can cause bearings to fail in even the most perfectly built engine. Guy probably blows up engines left right and center and need a way to put the problem on someone else.

Yall worried about 200k Km engines, I have 320+ Km LS and every main and rod bearing looks like new…..

First !!!!!

You’ve contradicted yourself! How does the brg wear if it’s never to touch the crank!! Of course they touch that’s why coated brgs were created! Cold starts r prob the worst But yes brgs and crank touch it’s sadly unavoidable

You did it again, brilliant education 🫡

Why is he putting oil on the back of the bearing 😂

Great video
