You should also be an academic aside been a mechanic/technician. You are a natural teacher, your understanding of how a car works is phenomenal. Thanks for sharing!
Very timely for me, as I'm going to be doing compression/leak down testing on my motor for the first time. Felt fairly confident already, but was nice to have the confirmation. Much appreciated.
I'm currently doing a review video on the Performance Tool leak down tester, I will be doing a compression test as well, and we're rebuilding an engine for a customer. The timing! Awesome stuff
I think it may be important to know that the volume of the adaptor hose is a factor. The volume decreases the effective compression ratio. That may be the reason the spec covers a pretty wide range. The variation between cylinders is also important, I believe ( ?? ).
My wifes car has the same problem the hood blanket is soaked in oil.....the car runs but it leaks oil like crazy....it is a 20 year old 2005 scion tc 2.4l 2AZ-FE which is known to burn oil and leak oil but yea this series will give me some pointers on what to look for
Diesel's can be done the same way. They require a different compression tester kit because you remove the glow plugs instead of the spark plugs and the pressure is much higher, requiring a different gauge.
I had the opportunity to buy i believe it was this vehicle. The one i was looking at had a huge oil leak lol couldn't figure out where because ot was leaking everywhere so i passed. The car was very nice except the massive oil leak. I don't know anything about turbos
How would the compression and leak-down procedures be different for the Ford 2.3L 8-spark plug engines. Access to plugs under the rear of intake is very limited.
The engines with 2 spark plugs per cylinder, remove all the spark plugs from the cylinders that aren't being tested. The one that is being tested, leave one of the plugs in so the compression doesn't escape.

Thank you for this video! Looking forward to the next one.
Very good information, meticulous and to the point thanks alot👍
U make me. Work on my diff build with no ffear . Much love and respect brother
Very informative. I learned quite a bit.
very well done. thank you.

Woo hoo 200,000 congratulations
Thank you. I didn't know this.

Good stuff!
Thanks for a very good video. How would you go about doing a leakdown test, or compression test on a diesel engine?
Diesel's can be done the same way. They require a different compression tester kit because you remove the glow plugs instead of the spark plugs and the pressure is much higher, requiring a different gauge.
@@RepairGeek Thanks! I had problem finding a leak down tester kit for diesel engines, seems to more rare, but glad to hear its the same procedure
I had the opportunity to buy i believe it was this vehicle. The one i was looking at had a huge oil leak lol couldn't figure out where because ot was leaking everywhere so i passed. The car was very nice except the massive oil leak. I don't know anything about turbos
If there is a head gasket leak, would there be bubbles at the coolant reservoir?
If you are leaking combustion gas into the cooling system yes, you will have bubbles with the leak down tester.
How would the compression and leak-down procedures be different for the Ford 2.3L 8-spark plug engines. Access to plugs under the rear of intake is very limited.
The engines with 2 spark plugs per cylinder, remove all the spark plugs from the cylinders that aren't being tested. The one that is being tested, leave one of the plugs in so the compression doesn't escape.
Thanks for taking the time to help out. Appreciate it! @@RepairGeek
I just bought one leak doen tester from AliExpress i hope it do it's Job
Why does the leak down gauge show yellow instead of green when there is minimal leak down?
I'm assuming that's how they designed the gauge. I'm not a smart man though
I have a 5.7L HEMI with two spark plugs per cylinder. To do these tests I would only remove one of the plugs on each cylinder, correct?
Correct.
@@RepairGeek thanks. Great video. That smoke machine is well priced and reviewed on Amazon. HF Icon machine is way overpriced.
Almost everything at HF is overpriced anymore.
👍
Did you forget something? You don't want fuel to be injecting while testing or spark
I wrote the previous near the beginning when you hadn't mentioned removing the fuel fuse
