Bro when I tell you that I have never listented to Lil Boat but this is the realest line I have ever heard....I might have to start listening to some of his music.

Its getting to be just overwhelming expensive to buy, or get a vehicle repaired at a shop now, and too hard for an average person to fix them. Im 70 yo, vet and have been doing most of my repairs on the street, but now i cannot afford to have my 1983 f150 motor or head replaced. It has burned valve .

Thank you for this video so I could inform a client in better visual description.

[@ardoario4990]

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.

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.

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?

[@javonrichardson8666]

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.

[@headpainter1]

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.

[@TheExpact]

What did it turn out to be?

[@headpainter1]

@@TheExpact it's one of the projects still in the works. But I pretty much narrowed it down to a slow-moving valve probably gummed up. I added some Marvel Mystery Oil and some valve cleaner to the gas and oil. Need to try to tackle it again soon. I pulled the valve cover and none of the Springs are broken everything looks like it's supposed to. Don't currently have the money to pull the head and have it reworked. May pull it out this weekend in Tinker with it some more.

[@headpainter1]

@@TheExpact update. I started looking at it again and now I believe I have figured it out. I started thinking had to be something going on with the valves sticking or something. Then I thought lifters. It's never really made a ticking noise so I didn't think of them. I googled a misfire caused by lifters and it is definitely a thing. Makes a bit of sense now. I'm going to try tear into it soon.

[@headpainter1]

Replaced the 2 lifters for that misfire cylinder and put back together. Misfire is gone. This was a difficult one to diagnose. Most of the time it's either coils or icm or plugs.

AWESOME Video

[@spaceman6541]

Great video. I have 75psi on one cylinder. 100 psi each on the other 3 cylinders. Should it still start?

[@evansisco]

If it is within operating spec. Of ur engine yes but to me being a builder that sounds like it is a lot low on all of the cylinders. They should be around 180 and that would be a good cylinder.

[@CristianHernandez-px9uz]

Great video!!!💯💯💯

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

[@carproblemsmax]

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!

[@engineer3139]

My suzuki mehran showed 62psi in dry test and in wet test 170 psi in two cyllinders while 200 psi in 3rd cyllinder.

[@chasehobbs5255]

would bad timing chain foul plugs?

[@carproblemsmax]

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.

2002 Honda Accord low compression all have 60 psi

[@carproblemsmax]

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.

[@adrianpinder9897]

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?

[@Yanbrymenocu]

​@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.

[@headpainter1]

I meant when the car started running, compression fell.

[@FabianHernandez-uj5im]

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 :-\
