I’m a 76-year-old lady and I never have nor never will build an engine, but I still love to watch and listen to you!

You are the shop teacher that we should all have.

You can really tell when someone knows what they are talking about, no jump cuts no reading off notes just straight dropping all that wisdom on us. Thanks Derek!

A feller couldn't grab that play button fast enough! Bring the thunder!!

who here thought they were legit sitting in a engine building class lmao

Humor is great, but hearing technicalities explained and understanding the seriousness of poor quality work, is so refreshing.

I'm so glad that you're a mechanic and not a sexologist. ie: "OK, now that I'm getting down to my end here I'm losing my leverage. So I'm going to reach in with a couple of fingers and I'm going to guide it in."

It was cool to see "take it serious" Derek vs "I'll just pretend I didn't see that" Derek.

These three videos, needs to be shown in as many classrooms as possible....✊🏻🤘🏻🍻🏆🥇

I wish President Biden was as well spoken at explaining things. Lol 😂

A guy gets to a certain age when he just doesn't want to learn anymore. That same guy watches Derek throw an engine together while schooling him up at the same time and a guy actually learns to learn again. Dangit! Thanks for all that you do for a guy Derek.

Can we all just take a moment to appreciate how great his content is? A guy has enough jokes and puns to keep a comedian out of work. But also knows when to dial it back and be serious for a minute when talking about important parts. Keep up the great work Derek!

55 minutes = 2 years of school !

If you don’t do a full on “BRING THE THUNDER” when this beast fires up on the dyno I’ll be very disappointed.

This is one of the best, most informative, simple videos I’ve seen in a long time.

I love how you switch instantaneously from "It's junk, I don't care" to the very spirit of thoroughness and care when money has been laid down. Great stuff Derek!

I just finished working 12 hours and wasn't sure I had enough energy to keep my eyes open for 55 minutes. The next thing I know the video is over and I want to watch part two. There should be a two-thumbs-up button for VGG.

This man is the bob ross of motor building

I’m tellin ya, Derek needs his own show on The Discovery channel. I would pay for cable again just to watch.

Derrick, you’re as calming to watch as Bob Ross.
