,317 HP on the dyno is great, but did the rings survive? 💨 Ben Strader (@EFIUniversity) breaks down the art of the Leak Down Test. Don't just look at the gauge—listen to the engine to find the leak. Check out the full session here: wp.me/pcnYJ8-3oB

Think your block is clean? Think again. 🛠️ Lake Speed Jr. shows how much "stuff" comes off a freshly honed cylinder just by turning the engine over during assembly. The profilometer doesn't lie. See the full Rpk value breakdown here: wp.me/pcnYJ8-3SU #EngineBuilding

Nitromethane + stepping on it = "There will be repair work." 💥 Dennis Borem of PME Engines talks Clay Millican’s positivity, NHRA "hazards," and dyno-testing a classic Lake Speed Sr. NASCAR Ford C3. 🏎️💨 Full episode: wp.me/pcnYJ8-3zc #NASCAR #NHRA #EngineBuilding

One scuffed cylinder shouldn't mean buying 8 new pistons. 🏎️💨 Lake Speed Jr. is at the @EngineExpo using a "Liquid Plumber" hack to save a bore and keep the build on budget. Chemicals + Elbow Grease = Savings. See the results here: wp.me/pcnYJ8-3Oy #EngineBuilding

Clean parts = Less power? 🤔 Mark Cronquist and Jason Line share hilarious stories from the dyno room, including the time they called the news to check pollen counts because the cars were yellow! 🌼🚗 Catch the full episode at the Engine Performance Expo: wp.me/pcnYJ8-3qx

“Attitude and aptitude.” That’s what Warren Johnson hires for. Not ego. Not someone who “knows it all.” In this EPExpo roundtable, he explains why commitment (like investing in trade school) matters more than raw talent. Full segment here: wp.me/pcnYJ8-2Mc

We were taught to compare cam profiles the wrong way. Billy Godbold explains why modern low-shock valvetrain tech changed everything. This clip is from one of the most info-packed Expo sessions ever. Watch the full episode 👉 wp.me/pcnYJ8-3EJ #Camshafts #Valvetrain

Speed + feed = seal or fail. Tooling choice, RPM, feed rate, even a touch of WD-40—these details matter when you’re chasing the right surface finish for modern gaskets. Catch the full EP Expo deep dive 👇 wp.me/pcnYJ8-3RF #EngineBuilding #MachineShop #MLSgaskets

“You’re playing with fire.” Tony Bischoff on why he won’t put seat rings in some factory cast iron heads—and why cracking an unobtainium casting ends the conversation real fast. Real-world seat & guide advice from BES Racing Engines 👇 wp.me/pcnYJ8-3Px #EngineBuilding

Can a deck surface be too smooth for an MLS gasket? Short answer: not with normal milling. Long answer: the gasket dictates the finish—not the metal. “If you’re not measuring, you’re guessing.” Full episode 👇 wp.me/pcnYJ8-3RF #EngineBuilding #MLSgasket #SurfaceFinish

How much valve lift are you really getting? Ben Strader shows a simple at-home test to measure total valvetrain stiffness using a checking spring + dial indicator. Find out where flex is stealing your RPM 👇 Watch: wp.me/pcnYJ8-3ro #EngineBuilding #Valvetrain #RaceTech

Smoke out the tailpipe. Wet exhaust ports. High oil consumption. That’s not always rings — it might be fuel washing. Ben Strader & Keith Jones explain how to detect cylinder damage before it becomes fatal. Watch the full EFI vs. Carb episode here: 👉 wp.me/pcnYJ8-3Fe

Torque isn’t the same thing as clamp load, and confusing the two can wreck an engine. Rottler’s Ed Kiebler explains how friction, lube, and thread quality change real clamping force—even at the same torque spec. 🎥 Full episode here: wp.me/pcnYJ8-2Mt

Why you can dry machine cast iron—but MUST use coolant for aluminum. Cass Choate explains the science behind it: iron lubricates itself, aluminum gums everything up. Watch the full Performance Diesel – Part 2 here: wp.me/pcnYJ8-3HM #EngineBuilding #DieselPerformance

Before teardown, get the data. Lake Speed Jr. & Ben Strader explain why leak down testing is the fastest way to check cylinder health after a 1,300+ HP dyno pull, and share a simple setup tip that saves time and frustration. 🎥 Watch the full episode: wp.me/pcnYJ8-3oB

How do you really know where your lifter bores are? This clip from Engine Performance Expo 2024 – Ep. 35 breaks down lifter bore indexing, probing, and correcting variances using a Rottler F69 CNC. Watch the full episode on our site 👇 wp.me/pcnYJ8-3SJ #EngineMachining
