WHY ENGINE COMPRESSION IS LOW CAUSES (SYMPTOMS)

Why my engine compression is low causes. In this video I explain all the possibilities why engine cylinder compression is low or at zero. (No compression). Some of the common causes are blown head gasket, bad intake and exhaust valves, worn piston rings and cylinder walls.

I like this guy I wish he was running for president. He explains things to us this very way to understand and I like how he makes it simple for us… you !

Thanks

You also could use a borescope by removing the spark plug they are out already you could look at the top of the cylinders😮 to see if it has a hole

My car has never overheated but I have a misfire on cylinder 3, spark plugs, ignition coil, and fuel injector have been checked and all is good. Would you recommend I do a compression test? Or should I first check MAF, fuel filter or is there anything else I can do or check? Thanks for the video and sharing your knowledge.

Very interesting and helpful information.

[TheRealChirpy]

Very helpful and straight to the point thank you 🙏

Do a video showing how it’s done it’s more entertaining and better understood by newbies

Hi mate, very good explanation, I have a Mini Cooper s f56 2016 what could be a low compression on 4 cylinders and all of them are 20 psi what could be the cause about it I appreciate your reply thanks

I have a six cylinder, lighting bolt light came on and went into limp mode, after would not start, have fuel pressure, spark, good relays etc, no compression in 2 cylinders on one bank no compression on 2 on other bank, have full on 1 and half on last any thoughts? I asked u about timing on one of your other videos, by the way u have good videos straight to the point with necessary info

I did a compression test on my 2002 Ford Explorer 4.0l v6 4x4
It looks like cylinder 3 might be an issue, and 1, 2 & 3 is not consistent with 4, 5 & 6 cylinders.
Here's the readings I got.
Dry test. PSI
C1. 130
C2. 135
C3. 119
C4. 143
C5. 144
C6. 148
Wet/oil test. psi.
C1. 135
C2. 137
C3. 125
C4. 148
C5. 151
C6. 155
Have you come across something similar, and what do you recommend I would do next?

I just rebuilt my 170 Studebaker flat head engine. I am getting only 60 lbs and it does not want to start. Is it because there is no oil sealing things yet. Should I add an ounce of oil to each piston and let it sit?

One of my spark plug has no compression. Mechanic is saying too much money to inspect further and for me to buy a second hand engine. This sound right?

[MustangFourSix]

I got a 05 hemi 300c 5.7, 0 compression in #2 cylinder dry and wet compression test was 0 what else can it be

[eduardoviera]

was looking at old shcool vw bug listed as low compression after an overheat i think it might have been the engine seal or burnt valve

I have a 2006 X3 BMW bank 2 and 4 low compression. I changed plug, coils and value cover gasket. Still miss fire. I was told to try C-foam

[athenkosimagolorana]

On my hyundai i10 there's only one spark plug that have compression, the rest doesn't have, what can be the cause?
I lastly drove it on March

2008 ford explorer 4.0 new timing chains running great then died no compresion 4-5-6 checked visual of camshaft all tight and turning any suggestion

Hey, I have a O2 4.8 LS. I have no compression on cylinder two but when loosen the rocker arm I get full compression, what could that be?

[Shadowffect]

I have P0300 and P0301 & P0302 and both cylinder 1 and 2 are at 80 and 90 PSI compression and the car is misfiring on both cylinders. Replaced all 4 coils and spark plugs and still does it. Have any idea what this may be or could mean?

[silvasdairy]

Honda pilot 2012 V6 cylinder 6 low compression..
changed all the plugs, coils injectors Fues checked after..mechanic said.. need a new engine..any idea???

[hendricks]

Do you know about ford trucks? I got a 91 Ford f350 7.5 and i replaced almost everything new and still misfires. MAP sensor. Purge valve. TPS. EGR valve position sensor. Fuel injectors. Spark plugs and wires. Distributor cap and rotor. Ignition coil. ICM. Air filter. I even did a engine flush. I even check the PCM. Coolant temperature sensor. Air intake sensor. Like its not hold idle. One minute its ok then next minute, it misfires. Then back to running fine. Then back to misfire.
