Nice video! Interesting that the belt (and therefore cylinder 1) were on the driver side, as all the 4 cylinder cars I’m familiar with (VWs and Toyotas) have those on the passenger side.
Well I just did it in my junker Opel astra and it had 110 psi on 2 cylinders and 120 on the other. Since it was raising the pressure in my cooling system a while, but now stopped I will just drive the stupid thing conservatively till it is dead. It needs a serious engine work and I'm better to buy a lower mileage Toyota and be happy and don't mess with stuff like that! In case you are wondering my vehicle has 185,000 miles currently. I'm the third owner. I've done all the brake jobs, timing belts, pulleys, tensioners, I change the oil and filter religiously every 4,000 miles. Well it might last a year more, but atleast I know I shouldn't drive that car for long distance places because I can get stranded somewhere🥵😂😂😂😂. I am really thinking of buying a Toyota Avensis Station wagon. They have a lot of room, nice interior,and will last me a lot longer since I will change all the fluids, filters, inspect it and so on.
@@joebagofdoe4762 Despite burning a bit of oil, for now the engine works fine. The coolant leak was from a hose and I repaired it.

I'd like to have a bad example to show you guys, but don't at the moment. Here's my tips: -Check if compression numbers correspond with factory service manual. -Make sure there is less than a 10% difference between the highest and lowest cylinder. -If you assume there is a bad cylinder, then pour some oil into that cylinder via the spark plug hole and run the test again. If the compression goes up, then the piston rings are worn. If the numbers remain the same, then the valves on the head may be the issue.
I have a 2006 Mitsubishi Outlander. I do a diagnosed. An it said i need a camshaft possition. Sencor. But the engine. Light wasn't on. When a was driving. But it did shut rite off on the road.. A was thinking if i should do a compression test before. I buy a cam sensor.
If you warm the vehicle up wouldn't that make it easier to damage the spark holes from the heated soft aluminum/metal.? I thought compression checks were done while the engine was cold.
Good question. Scotty says warm it up for 5 minutes then take out spark plugs for compression test. Haynes manual says "...allow the engine to cool before removing or installing plugs".
@@GTContent Yes possible but the question is - is it a good idea and are you risking damage to the head threads? I chose to run my car briefly and let it cool down for a while. I got good results on my 16Y8 with no apparent damage. Thanks for you video!
After you warmed the car up to operating temperature , you turned the car off to remove the fuel pump fuse, spark plugs, and wires . can you do a compression test with a car that has a crank no start problem? Where it often will not completely start up at all?
GT CONTENT, why didn't you disconnect the ignition system to do a compression test? I'm not sure why auto tech disconnect the ignition system to do a compression test
Hi, the wet reading on one of the cylinders is lower than dry reading..what could be the inference..? I have done dry & wet compression test on my VW Polo 1.2 TDI..the reading is lower in the wet test than the dry test on cylinder number 3..? Dry: 1 - 26.7 (Bar) 2 - 26.5 3 - 27.8 Wet: 1 - 27.6 2 - 26.7 3 - 26.3
Looks wise, I am a fan of the STI blob eye. The EJ25 is known to have weak ring lands (use this compression test video to find out if you're checking one out 😉) but does have a more durable transmission. It is a good project car, but costs more money to make power compared to the EVO.
Well my stupid mechanic did not disconnect fuel while doing the test, and of course u know what happened next. 😡 However they distinguished the fire within seconds and nothing happened...the question is did that affect my engine by any means?
I didn't depress may gas pedal and i got 120psi might be higher when i do depress it next time.I seen some videos of mechanics not pressing the gas pedal engine cold with good compression, it's confusing sometime
I'm looking into getting an older Ford van from the 1960's. It also comes with a parts van of the same make & model. I don' t know if either vehicle has an engine or whether or not the engines run & I haven't contacted the owner about this. Is it possible for me to run a compression test on both vehicles, before I get new hoses, spark plugs, etc. Thanks
You can do cold as long as it's consistent, but warm is the preferred because the engine is operating temperature when you're driving the car and that's when the ring seal really matters.
best video on compression tests. short and comprehensive. thanks man
Thanks for the simple and easy explanation ☺️
You're welcome.

This is the most accurate comment I’ve ever seen🤣🤣☠️
This engine looks very similar to the 7AFE in my 1998 Celica, very strange but also cool, being it’s in a Honda!
Excellent description. Are the two cranking measurements similar to a dry/wet test?
Thanks for the teaching. 👌🏿👌🏿
Thanks a ton, great work!
Thank you for watching.

Can you make a video on how to diagnose bad compression
Thanks

-Check if compression numbers correspond with factory service manual.

Why you take two measurements, which is the valid the 4 cranks or the 12 cranks?
GTC... ummm when’re you gonna drop your TMW Supra M40i video mannnnnn!!! Quit stalling!! 🤣🤣

Good question. Scotty says warm it up for 5 minutes then take out spark plugs for compression test. Haynes manual says "...allow the engine to cool before removing or installing plugs".
Still possible to remove spark plugs while the engine is warm.

Cool
After you warmed the car up to operating temperature , you turned the car off to remove the fuel pump fuse, spark plugs, and wires . can you do a compression test with a car that has a crank no start problem? Where it often will not completely start up at all?
Yes, as long as it cranks.
GT CONTENT, why didn't you disconnect the ignition system to do a compression test?
I'm not sure why auto tech disconnect the ignition system to do a compression test
I was told to pull ignition fuse so that you don't blow the coil. And that someone had that happen. I guess it can arch to a ground and ruin it.
My y8 had 170psi but after head gasket replacement the compression droped low 120 130psi
i have cilinder 1 at 180 only ... they Say i got to tune the valves now . since my engine got rebuild.

3 - 27.8
Wet:
1 - 27.6
2 - 26.7
3 - 26.3
Don't you need to unplug the connector to the distributor?
You should, but it's not necessary.
Is this the D16Y7?
200 psi is quite a lot of pressure. Do you know why it does not all go out the exhaust?
The valves are all closed when the piston is at top dead center.
Does your engine is stock? If not what did you do on it?
How do I know which adapter to use
What is the thread size? Is the m18 on your tool?
Is 120psi low for a carolla 09 on all 4
What's your opinion on the Subaru STI an the EJ? Is it a good project car?
Looks wise, I am a fan of the STI blob eye. The EJ25 is known to have weak ring lands (use this compression test video to find out if you're checking one out 😉) but does have a more durable transmission. It is a good project car, but costs more money to make power compared to the EVO.
Yo man love your vids. But why are asians so good at cars?
Not sure if it's an Asian thing. Lol Just like any other hobby, it's most likely because the person has a lot of interest.
Asians aren't good at cars, they're good at EVERYTHING.
So after you cranked it 4 times did you release the pressure and then crank it 12 times or do you crank 4 times then crank 12 times ? Thanks
Don't release. Only release after the 12 times so that it'll build pressure.
Is it vtec ??
No
stuck new ka24de engine compression any one knows?
Well my stupid mechanic did not disconnect fuel while doing the test, and of course u know what happened next. 😡
However they distinguished the fire within seconds and nothing happened...the question is did that affect my engine by any means?
I don't think so
bruh i wasn’t holding down the gas pedal, makes sense why the gauge was reading 0 lol
I didn't depress may gas pedal and i got 120psi might be higher when i do depress it next time.I seen some videos of mechanics not pressing the gas pedal engine cold with good compression, it's confusing sometime
where did you buy that compression gauge?

what happens if the throttle body is not open? will the compression be lower? ( just did a test not pressing the gas pedal).
Yes, numbers will be lower giving a false reading.
@@GTContent Do you press the gas pedals for all cars doing compression test? I have a 2009 BMW
@@bobbyz23 yes
Yeah. Compression sounds like it needs a K20 😅
😂
No wet test ?
No. Wet test should be conducted if the results vary greatly from cylinder to cylinder or if the motor is not warmed up.
@@GTContent Thank you.
How about a 4.7,have to take out all 16 plugs
Yes, you want to conpression test each cylinder to check it's health.
I thought u were no meant to have a warm engine
You can do cold as long as it's consistent, but warm is the preferred because the engine is operating temperature when you're driving the car and that's when the ring seal really matters.
