    That is a good reading as long as it was 90 pounds or higher. So it could be spark plugs, wires or coil. I bet on wires or spark plugs. This was a 5.7 HEIM RIGHT ? oR AN INJECTOR ON THAT CYLINDER look at the spark end of that #7 spark plug.

Pull #7 spark plug perform a cold compression test, then perform a hot compression test. What were your reading?

SOURCE: engine code p0307 cylinder #7 misfire

It could be carbon deposits on valve seats keeping valves from totally closing. You can try getting you a can of motorcraft PM3 top end engine cleaner and get engine up to operating temp then remove one of the small vacuum lines from the intake and draw the contents of the can slowly into the engine.After you have drawn in the contents shut engine off and let it soak for about 45 minutes then crank it back up and let it run until it clears. Now it will smoke like a forrest fire while you are doing this so don't be alarmed,just tell the neighbors you are spraying for mosqitos.This may cure the problem. If not you may be looking at a valve job.
This can be verified with a compression test if this is what is causing it.

SOURCE: Over-drive shudder 45+ mph

The P0308 could be showing up because of the torque converter shudder. Go to your local trans shop, or parts store and get a bottle of Smart Blend. It is the best additive for TCC shudder. Do Not put anything else in your trans. This stuff works, and it is the only additive recomended by GM, and Dodge.. It is not but about $10, if your converter in not to far gone this will help. If it is all you are out is $10. Good Luck.

SOURCE: ticking noises only when you start then goes away

Depended on the mileage and if the truck has been worked hard. It could be a few things, A worn out hydraulic lifter, a worn crank bearing, old engine oil that needs to be changed, or maybe a tired oil pump. Try using a stethoscope to narrow down where the ticking noise is loudest. From there you will have a better idea what the cause is. Take a look at the oil pressure, see if it takes to long in the morning for the oil pressure to start building. Every time you look at something different it will help bring you that much closer to the solution.

SOURCE: #7 cylinder misfire dtc p0307

Best place to start would be with spark plug and have a look at it. Wet with fuel would indicate no spark, carbon build up, bad wire or plug etc. If your familiar with testing at spark plug to confirm spark getting to plug, then do that first. If no spark to plug, coil pack would be next, or distributor parts such as cap, wires, rotor etc. If getting spark, then try cleaning and checking connections to injector. There are other more expensive things that may be causing it, but lets try the cheapest, most common and easiest first to narrow it down, and get back to me/us, if still having problem.

I have a 1996 dodge. ram 3500 with the v10. There is s knocking noise from under left valve cover. it goes away at about 2500 rpm untill it shifts then it's right back.


If it's upper engine noise it could just be sticking hydraulic lifters if the sound isn't constant. If it's more pronounced at a cold start that is probably all it is. A couple of things to try is Lucas Oil Stabilizer in your oil. If the sound reduces more than usual then it's the lifters. You can also try doing a seafoam treatment on the engine. There are several instructional videos on youtube for that. Also check to see if there are any Dodge v10 truck forums. They could have more specific info on the lifter tick.

A ticking sound on a 06 ford f150 super crew 5.4L


Ticking sound could be coming from a Coil-on-Plug, or a pcv valve, or (hope it's not) a valve lifter which could be sticking. Sticking lifter noise often disappears when rpm's change, or the noise comes & goes. try changing the motor oil & filter right after adding an Engine-Flush Treatment to the motor oil, running the engine for 10 minutes at idle with treatment added to the oil, then draining the oil & changing filter while oil is still very hot. That last part is very important, so be careful not to burn your hands - be careful. -- The sticking lifter is a likely cause if motor oil has not been changed at frequent intervals in the past (every 3-4K miles) -- dirty oil causes sticking lifters.

2003 dodge ram has light tick for a minute at cold start then goes away


The 'light tick' is most probably a valve lifter. The valve lifters in the engine are hydraulic, and are pressurized by the engine's oil pump.
When the engine gets some mileage, say 60 or 70 thousand miles or more, the engine is just not as tight as it once was. What happens is that the lifter loses its pressure when the engine is not running, because there is some wear. When you start the engine, the lifter takes a few moments to pressurize, and makers a ticking noise until it does. The 'ticking' is the sound of the valve being hit by the push rod, which is being pushed by the lifter. Once the lifter is pressurized, the 'ticking' sound stops. This is a very common thing for engines, it will eventually happen to nearly every one.
Sometimes, thin, old oil can cause this. If you have not changed the oil/filter in a while, you should do it now.

This is nothing to really worry about right now, but it is a sign of engine wear. Just be sure to run the proper oil in the engine, and do all the proper maintenance.

Keep hearing ticking sound from engine change oil and went away but coming back


Not really uncommon for a higher mileage engine. As long as its just a tick no big deal.. If you rev it up a bit and it goes away then its a hydraulic lifter. The fresh oil is a bit thicker and keeps the lifter pumped up better. You could go to a heaver weight oil and it would help but really its nothing to worry about.

When i spped up my truck makes a ticking sound ..what could that be?


It is more than likely the lifters ticking. After a lot of miles then the hydraulic lifters don't hold oil pressure and start ticking. Engines will run for a very long time with the lifters ticking. I have a 1972 Nova that the lifters have ticked on for about 10 years and it still runs fine.

Is it necessary to replace valve lifter or can you adjust lash to reduce clatter on dakota v-8


hydraulics lifters you must replace as they will wear out.

solid tappet lifters can just be adjusted for. Unless you have some custom old engine in yours I'd imagine yours is the first.

You might also try running some pennzoil or quaker state oil to reduce clatter. They're wax based and will often do wonders for semi-clogging the right areas while keeping the other places open. Great for hi mileage motors.

Does 2002 Jeep Grand Cherokee V8 have hydraulic lifters? I posted a question a few days ago regarding engine loud ticking which sounds like lifter noise. It doesn't have that deep sounding knock. I went to...


I would not believe any thing some parts store loser told you. Theres not a V8 built that doesnt have hydraulic lifters, unless its some fancy racin engine. It has hydraulic lifters, but unless you dont change your oil every 5k miles and/or use some cheap oil, there should be no problems. You should have a real mechanic look at it, and verify that you have good oil pressure. If it does, I would change the oil and use some MOBIL 1 and drive it, the oil will clean the lifters somewhat. If the eng has low oil pressure, that will need to be addressed.
