**Fuel Trim Issues**

If you notice that your fuel trim on bank one is minus 10.1 and it's minus 12.5 on bank two, it means that your engine is running richer than usual on both sides. The first thing to check would be the fuel pressure regulator, as a faulty regulator can cause too much fuel to be delivered to the engine. This will result in rich running on both banks of the engine. If the issue persists, it could be due to a massive leak somewhere in the system where extra fuel is seeping into the engine.

Another possibility is that the mass air flow sensor is malfunctioning, as this can also cause the engine to run richer. However, if all three readings are close enough, it's likely that something is affecting both banks of the engine. In such cases, checking the fuel pressure regulator or inspecting the system for leaks would be a good starting point.

Fortunately, replacing faulty components like the fuel pressure regulator can be done relatively easily and affordably. Auto parts stores like Autozone often have liberal return policies, making it easy to exchange a faulty part if it doesn't fix the issue. If the problem persists after replacing the regulator or checking for leaks, further investigation may be necessary.

**Head Gasket Issues**

If you suspect that your engine has blown head gaskets, it's essential to address the issue promptly to avoid further damage. The presence of hydrocarbons in the cooling system can indicate a blown head gasket, and removing the head to inspect the condition is usually a viable option. Volvo engines are generally considered reliable, but they do have a reputation for experiencing blown head gaskets.

In this case, replacing the head gasket would be the most straightforward solution. A head gasket kit should include all necessary gaskets to replace the damaged ones, making the repair more manageable. It's worth noting that some modern engines may require specialized tools or techniques to access the head gasket area. In these cases, seeking professional assistance from a qualified mechanic is recommended.

However, if the issue can be resolved with basic tools and repairs, it's certainly doable as a DIY project. The advantage of working on an engine like this is that the components are relatively accessible, making it easier to diagnose and repair issues without having to pull out the entire engine.

In your case, you had a Volvo V7 T5 with a blown head gasket diagnosed, which was caused by hydrocarbons in the cooling system. Thankfully, your son was able to use his skills as an aircraft mechanic on Chinooks to become a chief engineer, taking him further than just repairing cars. If you're considering tackling similar issues with your own vehicles, remember that it's always better to seek professional help if unsure or uncomfortable with any repairs.

**Experiences and Insights**

In this particular case, the individual had an experience with their son who was initially interested in pursuing a career as a mechanic like himself but ultimately chose to work on helicopters instead. His son learned to be an aircraft mechanic while serving in the 101st Airborne Division, eventually becoming a chief engineer. This highlights the diversity of skills and experiences that can be gained through military service.

The individual shares his own experience with repairing cars, trucks, motorcycles, and even helicopters, emphasizing that each vehicle has its unique challenges and requirements. While flying Chinooks is undoubtedly an exciting experience, it also comes with significant risks due to the presence of rockets being fired at them while in flight. However, as a mechanic who has worked on various engines, he acknowledges the importance of staying up-to-date with modern engine technologies and techniques.

Remembering to ring that bell when watching his new car repair videos will help ensure you don't miss out on valuable information and insights from this experienced mechanic.

"WEBVTTKind: captionsLanguage: enrev up your engines everybody knows i'm not a gm fan but this is a 96 and it's a 2500 check it out it's pretty clean custom bag huge bed best of all babies only got 109 000 miles on it got a big old v8 engine and look it's a 96 what's that metal is it plastic no is it going to warp with the heat no it didn't make them as cheap as they possibly could like they do today with all this plastic crap i'd be old but with that mileage if you could find one of these when they were solid built start showing up now granted this one's old 96 and the ac doesn't work anymore you can see the compressor doesn't come on this may be old but the ac system is a more modern style i did a video on a 70 oldsmobile which is a gm product right it had the old giant radio compressor and it still worked perfectly fine these are weak compressors you probably have to replace it if you want to have ac in the vehicle not all that bad here in tennessee you don't care all that much with an old work truck the engine listen to it solid because it's only got 100 000 miles on it you can hear when you close the hood it's a solid vehicle since it's hot we'll roll all the windows down take it for a spin got it reversed nice and smooth big old truck you're high up in the air of course it drives like a truck it is a pickup truck it's got a solid feel front end seems pretty normal after all it's only got 100 000 miles on it so we'll take it out where it belongs out on a country road see how it does but while i'm driving around i notice there's no wheel bearing hum there's no whining bearings there's no lag the brakes work perfectly fine i don't hear any suspension noises clacking clunking so we'll go to our little test trip here out of the country we'll come to a stop where this car gets out of the way since there's nobody behind us and let's see what this old truck can do still got some get up and go just decent for the mileage front end is stable basically it's a big odd american pickup truck when they were still making them go to gm back in 1996. now of course most of these are gonna be all worn out with four or five hundred thousand miles on them you found one like this it's only got a hundred thousand miles on it you want a big pickup truck snap it up fast who says you can't go back in time hey i'm back in 1996. still a really good pickup truck what really amazing about this truck is look at the interior it's a 96. the original interior is still in excellent shape hey they used to make things pretty good i'm sure the odd cigarette burned in a rug but hey it's a pickup truck now maybe old but it's a 96 so i can use a modern computer on it too so we'll hook it up there's a data port and we'll turn it on scanning it runs fine but it has these weird codes c2 c10f1 and c2 c18 f1 well the brakes are working fine now but that particular code is for the sensor for the master cylinder pressure saying that there's an error in the data coming out of it hey it's an old truck you know i mean if the master cylinder goes bad when you stop on it'll start sinking it doesn't do any of that that's a wiring problem yeah it's a 96 you know these things are going to wear out the warning systems wear out but the vehicle keeps going so that's nothing to worry about so let's look at data live data the mav sensor is pretty normal everything so far looks good now it's an old truck okay so the long-term fuel turning on bank one is minus three so it's running a little rich on bank number one yeah it's an old truck right but look at the long-term fuel turn on bank too it's zero that's why it's got a little bit of a roll at an idle because bank one probably got a leaky injector you can try cleaning them but bank two was running perfect so yeah it runs a little rich on bank one probably the fuel injectors maybe a little dirty run a little cleaner but otherwise the truck runs really fine and a pretty good truck with that low mileage now yes it's a vortex system and you can see one side's run a little bit reach at some point in time it's probably going to have to have that vortec fuel injection system replaced it's all plastic stuff inside the engine eventually the plastic is going to go bad but it's a doable job yeah you'll pay a thousand something bucks to do it but then away you go and it runs good enough now it doesn't need anything right now but in the future it'll probably need that but i mean really you're looking at seventy thousand dollar new pickups so you put a thousand or so in it over the years that's not a solid well-built truck for a decent price beats the heck out of buying a brand new seventy thousand dollar one it probably isn't made as well as these old ones are and here's some bonus questions and answers big mama 68 says what will happen if i use the spark plug nine foul or number six on my chevy silverado because i have oil in this wire you put an extender the spark plug goes up higher so it might not get as much oil it may not run exactly perfectly especially at idle but you got 212 000 miles if you wanted it to run evenly you'd have to put eight extenders one on each one so they're all exactly the same again but let's face it you got two hundred twelve thousand miles on an 08 silverado it's only gonna last so long right it's got a certain life span that's as long as it's going to last go ahead if it works drive it see how long it lasts because eventually the engine's just gonna burn up and you have to replace it you might squeeze a little bit more mileage out of it i mean go ahead and see what happens if it runs better a lot of times it'll make them run better for a little bit of time you're still gonna have to change the spark plugs out every so often because they're gonna be clogged up with oil but it can make them last a bit longer just like your engines only got a bit left anyway so what the heck bishon 55 says i got 2018 mustang the long-term fuel trim is off the long-term fuel trim on bank one is minus 10.1 and it's minus 12.5 on bank two all right okay you got a v8 engine one's running a little bit richer than the other but it is running rich on both sides first thing i'd check would be the fuel pressure regulator if it's given a too much fuel that's what's going to happen and both sides are going to run rich and then it's got to subtract fuel if you're really unlucky it could be all the injectors just warning the dribbling in but normally if both sides i mean -10 and -12 are close enough that something's affecting all of them which could be the fuel pressure regulator or you got a massive leak somewhere where extra fuel is getting into the engine or you might even check the mass air flow sensor it could be if that's wrong it's going to make them run rich so it's going to have to subtract a bunch of fuel both sides they don't cost all that much you go to places like autozone and get a new one put it in if it fixes it's great and if it's still exactly the same they have a pretty good liberal return policy in a lot of those stores like autozone you just say ah that didn't work and then they'll give you your money back you could try something else i've had people do that for years it's the one advantage of stores like that most stores you go to a dealership and they're just gonna afford dealership you buy it they're not going to let you return the thing but a lot of the auto parts stores will so you could try it if it didn't work you could take it back and that would be the quickest easiest thing to do i'd try that first and if not that then easily it could be the fuel pressure regulators dripping a little and sending too much fuel to the whole thing but that is way too rich when it's subtracting that much fuel you do have a problem flynn recess i think i got a blown head gasket i got a 0.5 volvo v7 with a blown head gasket that's what i was told because the mechanic said there's hydrocarbons in the cooling system and said i should throw the engine by another but it's a t5 with a turbo and it's hard to find one should i scrap it or replace it all right here's the thing volvo makes pretty good engines but they always have problems with blowing head gaskets i would get it fixed because you can work on that engine in the engine compartment you don't have to pull the engine out you just have to take the head off and the way those are designed they're not that bad of a design you can get the intake and the exhaust off on the vehicle and get like wires or something to when you unbolt them to pull them to the side and hold them then you can take the head off put a gasket and put the head back on put the exhaust manifold and the intake manifold back on it can be done i've done it by myself i'm not that strong because instead of having to pull all that crap off you can just unbolt the exhaust on both the intake move it out of the way wire it to the fenders or something so it doesn't get in your way then pull the head off gasket and put it back together i've done those and they're not that hard to do i would do that what the heck they're solid engines they generally never warp the heads of the blocks i would just replace the gasket you had a head gasket kit with all the other gaskets too while you're in there but i would replace the head gasket if i were you they're good engines and a lot of times they just blow like that john grant says scotty i'm surprised your son didn't become a mechanic like you did you steer him away from it no he actually was but in 101st airborne learned to be an aircraft mechanic on a chinooks and he ended up as chief engineer so he went further than me with that now they're not cars they're helicopters big old turbine engines and all that stuff and then they were flying around afghanistan doing missions people were shooting at them too so a little bit different than lying in the driveway la dee da fixing cars having people shoot at you and you got to fix it in the air if somebody puts holes in it because she's the chief engineer so he went a little further than i did i just do cars trucks motorcycles i've ridden around the helicopters they've got to admit it's a lot of fun but i don't know how much fun it is if you're in and people are shooting rockets at you so if you never want to miss another one of my new car repair videos
