Engine noise on startup goes away after a few seconds... HELP!

Hello Everyone!

I have got a noise on Startup that last for a few seconds on my 2001 Durango 4x4 w/ 4.7 engine, at first I thought it was my exhaust manifolds leaking or making a noise, well I replaced both exhaust manifolds and put new Remflex gaskets on, I took off the belt to see if the noise went away, to eliminate the water pump, pulleys, fan, etc, the noise was still there So, I am back to the drawing board I have swiched oil filters, I was using Mopar filters, then I went to the Napa Gold Filter still no change in the noise it all I was running Mobil 1 5w30, then switched to Pennzoil Ultra 5w30 still no change, I downloaded a sound clip for you all to hear, ==== Thanks for your help!============

Are you talking a loud clatter for a brief second at start up? Almost sounds like timing chain noise to me...but I don't know why it would go away so quickly. Maybe a tensioner is bleeding down? I really don't know...

The audio is so compressed I can't pick out any weird sounds excepts a couple faint knocks on start up. Is that what you're talking about is the knocking noise? I don't see how a new oil filter can make an engine noisy, its gotta be an internal problem.

Lifter clatter at start up then oil gets to them and quiets down.

The 4.7 is OHC.. It doesn't have lifters.. It has hydraulic lash adjusters.. But that sounds like what it is. My truck had a similar noise, which went away after I flushed the engine.

I forget where I saw the recipe, but I've used it (about 30,000 miles ago) and this stuff works like industrial engine draino - the crap that comes out looks like oil that's been in service for 60,000 miles. You will need 3 cheapo oil filters (they'll only be run for 30 minutes each), one of your normal oil filters, two gallons of kerosene, one large bottle of Marvel Mystery Oil, seven quarts of cheapo 10w30, and 6 quarts of your favorite 5w30 or 0w30 oil.
  • Bring engine to operating temperature then shut off
  • Drain oil thoroughly and change filter for one of the cheapos
  • Add 4 quarts of kerosene, 1 quart cheapo 10w30, and 1 pint Marvel Mystery Oil to the crankcase and start the engine.
  • DO NOT REV THE ENGINE OR DRIVE THE TRUCK UNDER ANY CIRCUMSTANCES! IT MUST STAY AT IDLE AT ALL TIMES DURING THIS PROCESS!! Kerosene IS a lubricant, and it will protect your bearings at idle, but not much faster. Revving will cause you to spin a bearing and more
  • Allow engine to idle 30 minutes at operating temperature
  • Stop engine and immediately drain crankcase. Observe the color of what comes out.
  • Change oil filter for another cheapo
  • Refill with four quarts kerosene, one quart cheapo 10w30, and one pint MMM, Start engine and run another 30 minutes.
  • Stop engine and immediately drain crankcase. Observe what comes out - it will still be nasty but should be much lighter in color
  • Change oil filter for the last cheapo
  • Refill with FIVE quarts cheapo 10w30 and one QUART MMM. (This is just a 'final flush' to get rid of the kerosene.) Start engine and run another 30 minutes.
  • Stop engine and immediately drain crankcase (thoroughly - let it drain for a while so anything in the top of the engine has a chance to drip down). There shouldn't be much gunk left in the engine at this point, so what comes out should be much lighter than before.
  • Change oil filter for your regular quality one
  • Refill with 6 quarts of your favorite oil.

All "oil starvation" noises should be gone at this point.

was your noise similar to mine? could this clog up your oil pump?
