Question about 1998 Dodge Neon

2 Answers

Loud knocking or tapping sound when engine is cold

When i start the car in the morning i could hear a loud knocking sound for about two minutes, then it would disappear and the car would run perfect. i could hear the sound coming from #1 and #2 spark plug under valve cover. i took it to a mechanic he said try to change oil, so i did synthetic oil. the noise is still there and it is very loud in the morning.
could this be valves,piston slap, or fuel pump etc. my mechanic would not even open the valve cover or check for other causes.he said just change the oil. my car is a 1999 neon dodge SOHC 2.0L 4-cylinder automatic. would this hurt my car if i dont get it fix?

Take our oil pan off from under your car and there should be 4 to 5 covers over a rod bearing. wiggle each one of them and find out which one is loose. take that cover off of the one that is wiggling and get the rod bearing out. order a new one from auto zone and replace it. The knocking in your motor can end up where you will need a whole new motor. so get it done before its to late.

Knocking sound in Engine of Kia Sephia when driven longer.


It sounds like valve train noise. The best thing to do is have the dealer listen to it and see what the preliminary diagnosis is of the nosie. Is the engine full of oil and it has been changed on a regular basis or at least every 5,000 miles.

My 91 honda civic has a problem starting sometimes. It starts in the morning. Sometimes it will not start on a hot day and it will just shut off while driving occaisionally. Often it must cool off before...


It will be the main relay. It is a massive fuse under the coin tray. The joints become dry and need re-soldered. A very common problem on these cars.

The clunk is the starter engaging the flywheel, check that it is properly seated, a bolt might have come loose.

Motor started tapping loudly as if there was no oil, oil level was fine, changed oil sound quieted after 20 minutes, sound came back a couple of days later, went away the last couple of days on short...


hi this could be due to your hydraulic tappets, these will start to rattle if the oil has been low at some stage and the oil was to thin this normally sounds worse in the mornings on first start and gets quieter as the day goes on or disappears altogether, what you could do, is use an engine flush, put it in the engine and run it for a period of time, then empty the oil and refill with a thicker grade oil and see how that goes..hope this helps

Loud engine knock sounds like theconnecting rods in a 3.5L v-6 2002 trooper


If the engine knock is coming from deep inside the engine, the I agree, the rod is knocking.
If the sound is coming from closer to the top, it could be a valve lifter or push rod you are hearing. This isn't as bad, they last longer and synthetic oil or oil treatment helps.
If this doesn't happen all the time, if it's occasional or you hear a pinging noise, you could just have a bad knock sensor.

Some times it has a loud knoking when you start it up! oil presure good.


If this sound only happens when you first start it in the morning, and then goes away, then you are experiencing either lifter ticking, or piston slap. These both are fairly normal for this vehicle when it's getting higher in the miles, and before the oil gets to all the parts. Once you shut the engine off, the oil drains down, and it has to recirculate some of it. This takes a couple of seconds sometimes, and you hear this knocking sound when it happens, especially if it's cold out, or you are using thicker oil than recommended.
If the knocking sound continues after the vehicle has been running, then you need to have someone check it out for sure, because you could have a connecting rod knocking. This means that your engine is about to go, and you should not drive it.

1995 Mazda MPV Noise


if it's a knocking sound it could be worn internal compnents ie. rod bearings. if it's a ticking sound the valves may need adjustment.
either way a mechanic will have to hear the sound to properly identify it.

I am having trouble with my speedometer not working occasionally and now my seat belt light is coming on sometimes too. Is this the instrument panel cluster? Or something else? 1998 Dodge Neon. Backstory is as follows: -We take very good care of it and have one dedicated mechanic. -It has only had two owners; my parents and I. -We replaced the battery 2 months ago. -Mechanic checked to make sure the speedometer sensor was working. -We have had issues with the radio for years where it will randomly turn on and off, typically brought on by a stuffed trunk OR wet weather. -The speedometer works until we hit a bump and then the needle flies up and down or sometimes just stops working all together. -Mechanic has made mention of there being some Chrysler specific battery cable that is a smaller side cable and it is not in good condition. -Currently, my problem is that I can't find an old 1998 Dodge Neon in the salvage yard because yards are doing a lot of 2002 and newer vehicles and automatically crushing the others. The meat and potatoes of my question is what direction do I go in? And what of these symptoms ties to each other? And will adding new solder to the points on the panel fix it or is it something else? I'm trying to find least expensive to most expensive options and I'm rather handy but can't drop an engine or transmission or anything so keep this in mind. My handiness ends at resoldering the pins BUT I do have a mechanic I trust, but I fear that maybe I'm not combining symptoms properly. I have the money to repair an item I KNOW is wrong but not to chicken hunt around for problems.
