Great video!!!💯💯💯
Interesting one. Have a buick 3.8 series 3 v6 that keeps registering a dead miss cyl 4. I've checked everything and all good. 150 psi in cyl 4. Here's the monkey. When the car cranked during the compression check the gauge fell to 20-25 lbs. I'm thinking a gummy slow moving valve. Spark is great, new injectors and compression at 150 when cranking. I was about to tackle the intake gaskets when I stumbled upon this low compression when it started. Any thoughts would help. Thanks.
Evo shut off at light , haven’t started since compression reads 110 on cylinder 2? I tested sparks separately all sparked I have to go back and test at the same time.
I got my engine back from a rebuild using the same parts. Car is about 50whp short, but runs, drives, and idles fine. Would getting a compression test be worth it?
1 - You didn't read the, "As is", part of the sales agreement.
2 - Your girlfriend after her cross-country road trip - "Gears?!"
3 - Clyde really hasn't, "worked on no foreign car", before.
4 - After replacing the gasket you can't find your 10mm socket.
5 - Motor oil is, "pretty much the same", no matter what it says on the bottle.
What is coolant?
@@alexalexanderson8022 Yes, lol, and that.
I did read "As is" now I'm having issues😂
My suzuki mehran showed 62psi in dry test and in wet test 170 psi in two cyllinders while 200 psi in 3rd cyllinder.
I keep getting code p11ec repeatedly does any one know what could be the problem?
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.
Check compression
@@ouwat4life Thank you!!!
3.7 vqvhr engine 1st cylinder misfire already put new spark plugs and ignition coils. Low compression on 1st misfire all others are good plz help
Hey there! Sorry to hear about your misfire issue.
Even after changing the spark plugs and ignition coils, it seems like the first cylinder has low compression. Here are a few things you can consider:
- Do a cylinder leakage test to check for any leaks in the cylinder.
- Check the valves for any issues like worn-out seals, damaged seats, or faulty springs.
- Worn-out piston rings could be causing the low compression, so keep an eye on that.
- Also, check the head gasket for any signs of failure.
To get a proper diagnosis and solution, it's best to consult a qualified mechanic or engine specialist. They'll have the expertise to identify the problem and help you fix the misfire. Good luck!
2002 Honda Accord low compression all have 60 psi
Hi! Low compression across all cylinders could be caused by several issues.
- Timing belt failure,
- Worn-out piston rings or cylinder walls,
- Damaged or improperly adjusted valves,
- Blown head gasket,
- Damage to the cylinder head or block.
You need to check to be sure, but there are probably leaks. It could be cylinder, rings, gasket and/or valves, if I were to bet on something would be cylinders. Does your vehicle emits blue-ish gas?
@carproblemsmax my 2007 Nissan versa have a low compression too but its on cylinder 4 only I check the oil dipstick and my radiator I don't see any brownish or milky color on it so it's not a head gasket do you thinks it's a worm valve guides and seals? Because I make compression test today and they found out that my cylinder 1 2 3 is okey only cylinder 4 is low compression.
I meant when the car started running, compression fell.
No sound
Have 6 cylinder with 4 cylinders with no compression 2 on one bank 2 on other any thoughts? Timing ? Please help 😮got spark ,fuel pressure ,etc.
Either broke cam shaft or crank shaft I'd guess. Let me know how it turns out.
@@martinobrien1877 it was valve sleeves on this particular motor slipped down then springs was stuck making valves open all time
I thought timing and went that way until I got in there found out problem
would bad timing chain foul plugs?
No. A bad timing chain is unlikely to directly foul spark plugs. The timing chain's primary function is to synchronize the opening and closing of the engine's valves with the movement of the pistons.
Fouled spark plugs are typically caused by issues related to the ignition system, fuel system, or engine condition. Common causes of fouled spark plugs include:
- Rich fuel mixture. This can be due to a faulty fuel injector, malfunctioning oxygen sensor, or issues with the engine's air-fuel mixture.
- Oil consumption. If the engine is burning oil, it can lead to oil fouling on the spark plugs.
- Incorrect spark plug heat range. Using spark plugs with an incorrect heat range can lead to fouling.
@@carproblemsmax thank you
So basically i’m fucked
No, lol probably need new spark plugs
The joke is on this bastard My car has timing gears😅
must ? compress? challenge accepted... a 0 compression engine (patent 0 compress) no leaks WILL run on hydrogen since is explosive instead of just flammable like gasoline..
perhaps you should tell the how poor of a fuel gasoline really is, considering if you dont compress it... you get 0 energy from it :-\ ps this is 120 year old knowledge that big oil dont want people to know about :-\
Low oil level
