Depends on where the knock is coming from, might be a worn rod, mild piston slap, cran bearings worn or oil pump itself might not be maintaining sufficient pressure.

nice guesses guys but that aint it. blue dodge what the noise is from is inside your engine. Now don't get all worried about it as it ain't major unless it don't go away after awhile. See what is going on is your hydraulic valve lifters is leakin down just a little bit, and it takes a few minutes for them to fill back up with oil and stop clicken the way that older engines with miss-adjusted valve lash sound like. Once the lifters have filled up with oil it goes away, right? If you want a good example of this, just go out and find a engine with about 100,000 mi. on it that has sat for about oh say maybe 6 months and go start it up. The doggone thing is gonna sound like 20 little people are inside it with 2 hammers each till them lifters pump up. If it really bothers you, go ahead and change the lifters as it is not really all that expensive to do if you can do the labor yourself.

probubly just some piston slap.GM has had the same problem in they're 2.5's and some of the other engines. when cold , most pistons are actually a little egg shaped. this alows them to go "round " as they heat up to operating temperature.if the egg shape is excessive it lets the piston "rattle" in the bore till it warms up. will it hurt it? not usually,can it be fixed?yes,new pistons.hope this helps.

You need to have them check your rod bearings and mains. The mains can be checked with a special service tool. All they have to do is drop the pan. The rod bearings will need some plasti-guage. You should not be getting a Knock for 3 minutes. Is your oil pressure lower then normal? My friends truck had about 110 miles before it was out of warranty. The manufacture did not see this(no. 4 main knocking ) as a durability issue even though there is a service bulltin for this same issue for his year make and model. I will give you three guess's what oil he is useing. 5W30 Quaker State. He had to have the top end rebilt under warranty.

Sounds like piston slap. Many engines develope that with a compression change. Valve job or ring job if the end gap on the rings is too tight. Generally won't hurt anything but your pride. I had a GM 6 that did that every morning, didn't use oil and still ran good, but first thing in the morning it sounded terrible.

If it's the same knocking sound as on my '95 Dakota V6, it's coming from a bushing on the distributor, so I'm told by a mechanic I trust and pay well :). It happens on the vans also, costs a fortune to replace but doesn't need to be.

I just bought a Dodge 360, it has about 6000 k on it and just happened to notice a slight knocking sound when it was cold and I raise the rpm just a little, it lasts for 2-3 min, sounds like its coming from the front of the engine as I put my ear right on the oil pan while running and though I could hear it I don't think that was directly where the noise was coming from. I was wondering if it could poor a poor fitting wrist pin? once heated up it quiets down, not to say this knock is very loud

I can't believe you guys are actually comparing
rapping GM motors to a Chrysler! Ugh! The
GM 2.5L "Iron Duke" is not at all like the 2.5L
that Dodge used in the Dakota/Caravan/Spirit/
etc.... Besides, get the lower end wet with
even a little smidgen of coolant and see those
GM powerplant main and rod bearings come
a spinnin'!
Not so on Chryslers... Of course 2.5L and 3.0L
Chryslers leak oil like a Harley, but hey, you
can't have it all, right?
Anyway, spec the lower end as another viewer
suggested and see if things are off kilter. If the
clearences are sloppy enough it might be
worth your time to have a machinist spec out
your crank and make sure it hasn't suffered or
your new bearings might fail sooner than
needed...

I just got back from the dealer with my 99 Dakota with a 2.5 four. He tells me that it is a wrist pin knock and that the factory will cover the short block, but that I have to cover the labor since I am the second owner. TRANSLATION - there is a secret warranty on this engine that the dealer knows about. I am going to fight this all the way since I bought the truck with 8,000 miles on it from the Dodge dealer that I took it to.
He also told me that if I put any more miles on the truck that the factory will not cover any of the repairs, so I know that this is a true hidden warranty. Has anyone else run into this. There were 6 TSBs on this engine for this year for spark knock! Was this the early beginning of the problem that was misdiagnosed?

I would do as they say and agree to pay the labor. Once you go to pick it up pay with credit card. Once you have paid with credit card you can dispute the claim with the credit card company. Or you can sue them Chrysler after you are motoring down the road with new engine to recover damages. Their is one company that put the wrong offset bearings in the block at mains 1,2,3,4, so the crank is not supported at No. 5. This alows the crank to move around like a dog wagging it's tail. It makes a an awful knocking noise when it is cold for about the first 2 minutes then goes away. I found the TSB for this guy and his dealer ship did not belive him till I printed the TSB out and gave him a copy. The knuckel heads at that dealership did piss poor research and gave him the run around. You have to do alot of research your self and have to pressure the service writers to check these things out. You can not just listen to an engine and tell what is wrong without proper diagnosis/trouble shooting. It only took me 5 minutes to find the TSB for his truck.

I am going insane!! I know nothing about cars and I just took a loan out for a 93 honda civic. When I start the car it knocks. The knock is only heard when the car is driven before it warms up, not when idling. The knocking ALWAYS goes away, usually 5 minutes or so, just after it gets warm then it runs smooth as can be. What is this caused from? Someone please tell me that this is nothing serious!!!

I have the exact same problem on a 92 civic dx. Knocks on light acceleration on cold days until the temp gauge comes up past C. I've had the car since it was new and it started about 40,000 miles, and I now have 130,000. It gets a little worse every winter. I intend to fix it this year. I'm told it might be the temp sensor failing to retard the timing, or just simply I need to run 91 octane in the winter. I'm filling up with 91 tomorrow and also set the timing back a little.

THE NOISE THAT YOU ARE HEARING IS CAUSED BY A WORN WRIST PIN, BETTER KNOW AS A PISTON SLAP. THE WRIST PIN ALONG WITH THE RINGS SEE THE LEAST AMOUNT OF OIL IN THE ENGINE. IF A CHEAP BRAND IS USED OR THE OIL IS NOT CHANGED PROPERLY, THIS PISTON SLAP WILL OCCUR. THE 2.2L AND 2.5L DOGDE ENGINES ARE KNOWN FOR IT. IT'S NOT A LIFTER,A LIFTER IS A TICKING NOISE, THE NOISE MY VAN AND YOUR DAKOTA MAKES IS A CLACKING SOUND. IT IS NOT THE MAIN BEARINGS. THAT NOISE IS MORE OF A HOLLOW KNOCKING SOUND, AND IS HEARD AT IDLE BEST. A ROD KNOCKING, IS NOT NOTICED AT IDLE, IF IT IS THE ROD IS ABOUT READY TO BE THROWN. A ROD IS BEST HEARD WHEN YOU RAP UP THE ENGINE, LET OFF THE GAS QUICKLY, IF YOU HEAR A RATTELING NOISE, THATS A ROD. THE NOISE IS NOT THE RING END GAP BEING TO TIGHT. IF THAT WERE THE CASE THE RING WHEN REACHING NORMAL OPERATING TEMPERATURE, WOULD SEIZE UP IN THE CYLINDER BORE. AND IT IS NOT TO MUCH CLEARENCE BETWEEN THE PISTON AND THE CYLINDER. IF THAT WERE THE CASE, THEN WHEN THE ENGINE OR ANY ENGINE FOR THAT MATTER REACHED 50 TO 80 THOUSAND MILES WOULD HAVE THIS PROBLEM. ONCE AGAIN, THE LACK OF CHANGING YOUR OIL PROPERLY OR USING A CHEAP OIL WITH LOW VISCOSITY AND NOT ABLE TO HOLD UP TO THERMAL BREAK DOWN. I HOPE THIS HELPS.

Being an ex dealer tech....there is NO SECRET RECALLS! these bulletins you speak of are GOODWILL POLICY ADJUSTMENTS! if it was a recall, we would have to fix every god blessed car built even if there was no problem. Goodwill policy adjustments are made on a case by case basis. if you have a problem and you fall under the right criteria... you get help.

kyle,
I ONCE HAD A DAKOTA WITH THE 4.7 LITER ENGINE. I NEVER HAD THE KIND OF NOISE YOU HAVE HEARD. I HAVE NOT HEARD OF ANY PROBLEMS FROM THE 4.7, ALONG THE NOISE YOU HAVE. IF IT WERE A INJECTOR YOU WOULD HEAR IT ALL THE TIME AND IF IT WERE A LEAKING LIFTER, IT WOULD BE MORE NOTICABLE WHEN COLD, BUT YOU WOULD MOST LIKELY HEAR IT ALL THE TIME AS WELL. YOUR DAKOTA IS NOT VERY OLD,UNLESS YOU HAVE HIGH MILES, THE OIL WEIGHT THAT YOU ARE USING SHOULD BE FINE. THE ONE OTHER THING, YOU LISTED A FEW ADD ON PARTS YOUR TRUCK HAS. YOU DIDN'T SAY ANYTHING ABOUT HEDDERS. BUT IF YOU DO HAVE HEDDERS, I HAVE BEEN TOLD THAT IN COLD WEATHER THAT HEDDERS CAN MAKE A KNOCKING OR TICKING NOISE AT TIMES UNTIL THE HEDDERS WARM UP. ONE THING THAT YOU CAN ALSO DO. WITHOUT HEARING THE TRUCK MAKING THE TICKING NOISE WHILE RUNNING YOU CAN TRY THIS. THEY MAKE A OIL DETERGENT THAT YOU CAN ADD TO YOUR OIL. ONE OF THE MORE COMMON ONES IS CALLED CD2. WHEN YOU CHANGE YOUR OIL JUST ADD IT IN. DON'T SUBSTITUE THE ADDITIVE FOR A QUART OF OIL. IF THE TICKING IS COMING FROM YOUR LIFTERS, THIS EXTRA DETERGENT IN YOUR OIL WILL HELP CLEAN YOUR BLOCK,RINGS AND LIFTERS. YOU CAN DO THIS EVERY OIL CHANGE IF YOU LIKE. IT WILL NOT HURT A THING, ALSO MAKE SURE THE OIL YOU BUY HAS DETERGENT. IT WILL SAY ON FRONT OF THE QUART IF IT IS NON-DETERGENT OIL. HOPE THIS HELPS.

kyle,
i just got your email and the other email from texas todd. your 4.7 liter engine has lifters in it. sohc just means that the cams are on top of the heads. older engines only had one in the center of the block. if you didn't have lifters in your head it would sound like the old mechanical valves/rocker arms. don't listen to todd. if he was right his engine wouldn't even run. also, go to the nearest dealership and ask if they have any service bulletins also know as (tsb's) for the noise you hear. keep tring, we'll find out the problem sooner or later.
