How-To Cylinder Leakdown Test

So how do i "lock" my engine so the pistons dont move 🤔🤔🤔

Please stop the music, it’s not needed.

I knew I needed rings!

Come on man!
Don’t need that ridiculous music.

BRP techs so slow to repair your toys that BRP said to hell with it let’s teach people how to fix their own shit. Lol

That F ing music takes so much out of this video, who ever produced it should have lowered its volume!!

Very informative video but the background music is excessively loud almost to the extent I stopped watching the clip.

Very good video.

The tips were super useful

feel like sh*t，my engine has 2 Doritos in it and it wont start

I prefer to listen to this without the distracting music

how to know leaking head gasket by compression test? bubble coming out from coolant during cranck? if engine start, bubble will coming out after thermostat open not after cranck right?

noisy asshole

No doubt very clear all the steps thanks.

Nice information 👍🏼👍🏼👍🏼😃

Amazing

Im facing a 1.5k worth of changing engine for my car, and I really want to avoid that, and these videos are helping me to believe my engine is still somewhat alive. If I do these tests and it shows that engine block and cilinders are fine, hopefully along with pistons and valves, I'll just need to change crankshaft and it should do it for now.

I feel like this video is slightly misleading due to outdated information. "Blue tinted smoke means burning oil" is from an old school perspective. Oil type, additives in the oil, temperature in which it burns will be factors that could easily change the color of the smoke. There are many cases where oil burning produces white smoke. Ever notice how leaking oil on an exhaust manifold will produce white smoke in the engine bay? Just an example.

Great Video, excellent visual, good Information 👍

The time of leak test do I need to remove all spark plugs

This is a great Video well explained especially for DIY mechanics with some knowledge and common sense.. Some of the videos by others droll on and on talk about everything under the sun and never get to the point.. Well done..

Excellent tutorial

Honestly, a series of videos of this calibre would be something I would happily pay to access as a masterclass - it's clear, concise and makes total sense. It has multiple, easily understood ways to confirm and diagnose. This is the maybe 20th LDT video I have seen as I teach myself to wrench on motorcycles - it is very, very good - congrats.

0 - 15% leakage is excellent, 16 - 25% is good... wow. Those sound like horrible numbers to me. When I went through Motorcycle Mechanics Institute the limit was 4%, more than that meant there were issues that needed to be resolved. Think about it, 10% combustion blowby past rings will acidify crankcase oil pretty quickly. 10% blowby past valves will quickly increase as valves burn during combustion. 10% water jacket leakage will have coolant spewing into the overflow quite often along with coolant being consumed in the combustion chamber. Comments?

amazing video! Thank you. will definitely aid my diagnostics. clear and to the point!

Great video!

Coming from the generation that is currently educated and employed, you really dont need music on your tutorials. It's incredibly out of touch with reality.

excellent video

Solid video man. This is a great educational video

Awesome information thanks a lot👍

Thumbs up, but thumbs down for the music.

This is super helpful

Outstanding. Clear, concise, easy to understand. Thank you!

Excelente video

STOP STOP YOUR GOD AWFUL MUSIIC OR NOISE

How white smoke indicates that there is a leak on the cooling system ? white smoke caused by oil burn

Too much noise during the video and We cannot understand what you saying. stop the music when when you explain

I couldn't hear a thing with that loud annoying fast beat music, is that really necessary?

To me I had burnt valve so had it replaced at the shop also replaced head gasket and timing chain cost a lot too

I like this video, aside from the loud rock music . . .

Song name?

Bingo...

thanks

Excellent video, clearly explains use of a leakdown tester but unless you're buying a top-end tester with calibration tables the '% leakage' figures shown on the gauge are meaningless. What you're really trying to measure is air flow rate out of the cylinder under test. The % leakage gauge infers flow rate by measuring pressure drop over a restriction in the body of the tester. But the pressure drop depends on the restriction size for which there is apparently no standard. The FAA for aircraft engines recommends a 1mm hole 6mm long. The one I have has a 2.25mm hole 3mm long. These will give vastly different % leakage values. Forget getting absolute values with a cheap tester. The best you can hope to do is compare leakage rated between different cylinders....and of course all testers, by allowing you to force air into the cylinder allow you to check where air is leaking out. So still worth buying.

The music so loud and distracting

best video!! most others just tell how to do the test but dont even tell how to diagnose the leakage.

Very informative

Lol... OK, what am I missing? "Remove all spark plugs... be careful when applying air to the cylinders as the motor may turn over"... explain how the motor will start without spark plugs. Or are they saying that the force of air will cause the cylinders to cycle / rotate, hence "turning over the motor"?

good vidio turn off music it adds nothing

I came for the leakdown test.

I stayed for the soundtrack.
