What is this noise? Clicking after start [Archive]

What is this clicking sound I hear after startup? It doesn't happen every time I start the car and it usually goes away after a couple seconds. It doesn't seem to be affecting anything.

Damn...! That is strange. It doesn't even seem to coincide with engine speed either.

Is it coming from the front or the back of the car? Have you stood outside and had someone else start the car?

My apologies... I really have no clue but I am curious to see if anyone else knows.

It's somewhere up front. I tried listening with the hood up but can't pinpoint the source.

Is your Marauder supercharged?

Ok... he is speculating a noisy lifter or rod that is starved for oil at startup.

Try videoing from under the car.

It almost sounds like the magnets in the starter but hard to hear over the dinging... Here’s a video I made many years ago.

Interesting...sounds identical to the OP's video. Magnets in the starter...:o

Have you done any PD?

Could be the starter - either the magnets or the drive stays engaged until it's kicked back

Radiator cooling fan - with the car running turn on the A/C - this forces the fan on. If you hear the noise disconnect the fan and try it. Of course you need to turn off the engine first.

hard to be a noisy lifter or pushrod when these motors dont have them

Just did one last Sunday.
Pull the belt, the tensioner is clacking.

Black marauder made the same noise, I seriously thought the engine took a ****!

You should buy the ribbed pulley, the smooth pulley and the tensioner all at once..

I bought mine at rock auto

lifter and pushrod go hand in hand so saying rod makes sense...

I saw the starter post and replaced the starter a few days ago. It didn't fix it.

I like the theory that oil isn't reaching somewhere on start. I'll try doing an engine flush this weekend.

I replaced the tensior and belt a year or two ago. It doesn't sound like it's coming from the front to me, but maybe it is one the pulleys. It does sound like a bad ball bearing.

If the car has had regular oil changes with high quality oil & filters then I'd not worry about flushing the engine. In fact you may do more damage to the engine.

What filter is on there now? You should use a Motorcraft FL820S which has the anti-drain back valve.

Take off the serpentine belt and start the engine.

BTW.. it's always a good idea to change all the pulleys and belts at the same time as they all get the same amount of use.

I believe these motors have bucket style cam followers. Correct me if I’m wrong

Of course, since posting this and since I've been opening the hood every time before I start to make a better video, the noise hasn't happened.

I pulled off the drive belt. I replaced the idler pulley, belt, and tensioner in 2015. I didn't replace the ribbed pulley, though. It sounds rough.

I assume it's not supposed to sound like that when I spin it.

That’s totally normal.......

I thought modern oils could give me at least 100,000 miles before a change.

Yep, but bearings don’t last that long

When I had it open before and heard it, it didn't sound like it was coming from the front. I'm not certain this will fix the noise. I would expect to hear it every time if the pulley is the source.

We'll see... new part is on the way...
