This is a common occurrence and results in all sorts of other pushrod related damages. When it comes to the carbon build-up that is a good old by-product caused by the direct fuel injection. With direct fuel injection the fuel is sprayed directly into the engine cylinders, completely bypassing the intake ports. Now, because there is no highly pressurized fuel going through the intake ports, cleaning them from any gunk build-up, there is nothing preventing them from getting clogged up.
This is actually a common problem on most direct fuel injection engines and not exclusive to the 6. Many owners with the A8 Transmissions have reported rough shifting and shuddering, especially between 1 st and 2 nd gear shifts. The problem was so wide-spread that a class action lawsuit was filed resulting in a fix being implemented by Chev. Apparently it had something to do with moisture in the transmission fluid used in production hence the problem being manifested as early as 20k miles.
The problem is easily resolved with a transmission oil flush and filter replacement. Worst case scenario, the torque converter will need to be replaced. The 62 v8 hp engine has been slightly modified for the full-size half-ton pickup truck segment. This is a decent upgrade version of the 6. Many hardcore 6. The ongoing battle for supremacy between Ford and Chev is amplified in the production of Fords Ecoboost and Chevys 6. Even though many Ford enthusiasts end up opting for the 5.
Whichever camp you prefer you have to admit, although not perfect, the 6. That is why mass air flow MAF issues can lead to transmission damage. This system really elevates the use of torque modeling for transmission pressure and shift control. This means that issues with just about any sensor on the engine can cause pressure and shift problems.
The need to have a quality scan tool and some quality training on systems other than just the transmission has never been greater. The LC9 was introduced in Originally, it was a flex fuel version of the LH6. Aug 28, Secondly, what causes AFM lifters to fail? We have found that most lifter faults are caused by oil pressure issues, or control issues. Mar 3, Dec 28th Aug 28, Vortec 5. One of the most prevalent issues on the Vortec engine occurred in Gen IV engines from model year to Cracked Cylinder Head.
Vortec Intake Manifold and Gasket Failure. This also led to rough idling, and the lack of power. Chevy 5. This caused the fuel and air ratio to be thrown off in a way that would limit the truck's performance. That ended up leading to more issues relating to misfires, rough idling, a lot of vibrations during acceleration and bad spark plugs again.
The fuel injectors in a Chevy 5. Because of that pressure and the high temperatures, they are under they can wear down faster than you might expect. They're also subject to being clogged or losing pressure. More often than not when these failed in Ecotec engines they failed completely. That meant it would either be permanently open or closed. In turn that means you are going to end up with a too rich fuel mixture or too lean fuel mixture because there is no control over the amount of fuel being injected.
The transfer case sensor shouldn't have anything to do with problems in the engine, but the fact that there were so many transfer case sensor failures reported with Ecotec3 engines makes it an issue. The transfer case transfers power from the engine to the front and rear wheels through the drive shaft. The transfer case sensor is responsible for controlling your trucks transition from two-wheel drive to four-wheel drive. If a sensor fails, the truck will be stuck in either two-wheel drive or four-wheel drive without the ability to switch back.
It could also lead to shifting between the two even when you don't want it. There are two fuel pumps in this system. There's a low-pressure fuel pump and a high-pressure fuel pump the high-pressure fuel pumps fail frequently as they're the ones that deliver the more pressurized fuel to the injectors.
The number of drivers experience what it's called piston slap , which is a kind of engine knocking sound after a cold start. The sound is caused by pistons rocking in the cylinder until they get up to temperature. The sound often resembled the noise you expect to hear from a diesel engine. Although this issue was generally solved by simply getting your vehicle at operating temperature, Chevy simply disregarded it as part of the normal operating procedure of the vehicle and foremost drivers it wasn't much of an inconvenience beyond that.
Even though there has been a number of issues over the last 20 plus years relating to Chevy 5. Chevy has produced literally millions of these engines over the years and the number that have had serious issues has only been a small fraction of the whole.
Because of that you can feel confident that if you are buying a Chevy that has a 5. That said, since we have seen a number of problems related to these engines, there's no sense going into purchasing a Chevy with a 5.
Knowing what the problems are means you know where to look or where to get your mechanic to look before you agree to put any money down on something.
