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

Very interesting and helpful information.

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

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?

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 good video man. Keep it up

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

Thank you for a time well done video

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

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

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

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???

I have a g35 wen into limp mode while driving now it won’t start n it sounded like low compressor

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

Great video 👍

Ecm also causes misfires p1399

Where are you located?

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?

We’re it’s your shop

On my 3.3 did the test my highest was only 90 all the others were 60 ...only 80k miles im guessin im goin to have to swap engines ?? Extremely rough n u have to mess with it to stay running ..if u try to give it gas it acts like its starved of o2 ..but no vac lines are bad , plugs n coilpacks changed ..fuel filter checked , ran absolutely fine all day never overheats. Never stalls no power losses...filled up with gas 20 minutes after the truck filled their pumps(didnt know they just had found out out from clerk next day ) ..went to start it and its sounded abysmal after starting...never in 53 years saw an engine be 100% fine and come out 12 hrs later be f@cked like this
