Sewing machine under the hood

[Chard]

I got a noise under the hood of my MM, So I had a good friend Of mine that works at a local police Depot as a tech give the MM a look over. He inspect and give me his opinion on the sewing machine noise under the hood.. he believes is a valve noise to be common on the Modular engines mentioned a TSB dedicated to this noise.. but with all the talk here in the forums about timing chain noise I made a little video and ask if you could please watch listen and let me know if this is the timing chain tensioner..

Your help is greatly appreciated..

Definitely not normal. It's not the common fuel injector clicking sound. Can you localise the sound to one bank or the other or is it in the front of the motor?

[camelgrundle]

I hear the common injector noise, but also hear the more erratic tic/knock sound which is concerning. Don't think it's the timing chains.

[Chard]

To add more information this noise is really only heard when engine is cold, or at rpm drop off. Once the engine reaches operating temp you can't hear anything at idle..

Try 5w30 or 40 and a motorcraft filter

[Turbov6Bryan]

So I hear a lash adjuster noise. It's the part right under the rocker...
Once the valve cover is off, only a rag and screw driver is needed

Here is a video. How too:

I just did oil change last week with castrol 5w-20 and a Motorcraft filter with a EFI service when i installed the JLT Intake. Trying to get the vehicle smogged today after work. I've been told to add some Lucas Oil Treatment to see if the noise would change plus its burning oil. Cant estimate how much yet, but i can see it at start up.

I cant really comment of any loss of power since i just got the car 3 weeks ago, but just on what i've done so far to it, i noticed a good change in driveability and performance

I tend to hear it more on the right bank more towards the top center (intake manifold area)

[RubberCtyRauder]

smoke at start up after sitting is pretty common, even among the mustangs dohc of those years. could be number 8 valve as there is poor circulation in the driver head at number 8 cyl. there is a head cooling mod to help prevent this, but won't fix it if already damaged. car would be running on 7 cyl. and is noticeable if number 8 has no compression.

How many miles? Mine had 170000kms , about 110000miles and sounded similar when I bought it. Was the passenger side composite chain tensioner. Replaced both tensioners and good now.

[ByronRACE]

Mine started that noise at 40k miles. Diesel oil cured it. 218k and counting.

How many miles on this motor?

How many miles on this motor?

Right under 74,000

[Turbov6Bryan]

Watch the video i posted?

[Chard]

Watch the video i posted?

Yes sir I did!! Did you run into the same problem I'm currently having?

[blkZooM]

If it doesn't harm performance in anyone and goes away once the engine is hot then it's simply the dreaded tick a good amount of these engines seem to make, mine use to do the same thing. If I remember correctly it's something with the cylinder heads

Correct.. something with worn valve guides. Ford states it will not affect performance, but only way to correct the issue will be either rebuilding the heads or replacing them with a new ones..

i wouldn't mind the noise, but it is quiet embarrassing to be honest..

Oh I get where you are coming from I hated it. Sucks to have a car that looks great, but sounds like it wants to come apart.

Exactly, Pulling up next to someone with the big intimidating Sedan with the V8 growl, only to Tick and rattle away at the light lol

[mm svt]

I'd still try a higher viscosity oil, it may help in a loud lifter or tensioner, high heat

[Chard]

i have about half a bottle of Lucas treatment oil left that i will add later this week.. wont be driving the MM til this Friday afternoon. hopefully that helps until i replace the lifter and or the chain guides and tensioners.

I had the same noise as heard in the video coming from my Marauder back in 2012. Ran normal other than making the noise for a few days. One morning, I stopped off and got gas, no issues, then when I went to start it, the car was stumbling real bad. No CELs. Ended up being the valve seats dropping due to overheating. Loss of compression on #8...

Definitely does not sound timing related to me, and I've done timing components on three 4.6s.

[mm svt]

Just oil treatment does not work as well as draining and refilling with 5w30 but would suggest 40

If I change back to motorcraft 5w20, the tick will come back within 3K miles. If I put this diesel oil back in, it will be gone within 3K miles. I think it's a sticky follower, and I think this junk has magic additives or something that works better. Whatever it is, it works for me.

How much Zinc is in the Diesel oil you show??:confused:

Zinc additives are not good for Cats!!:shake:

[Agent2006]

Kinda sounds like an exhaust manifold gasket leak...

It's in the specs, which are linked on that page. Very little. Formulated for modern catalyzed diesels.

[RF Overlord]

Byron, that oil has a 100°C viscosity of 11.9 cSt, putting it at the thicker end of the range (9.30 to 12.49 for 30-grade). That may be another factor in your experience.

[Chard]

To bring this back from the dead. Over the last week during my winter break i took the time and replaced all 32 lifters with new fresh oil and filter and Few things happen..

1. Noise is still there.
2. Car went hot on me once at idle and other while driving.
3. I know now how to properly bleed the coolant system.
4. Car started to misfire under load last night.

So at this time it seems the heads will need to be removed to fix what ever this is. My two choices are either, i can put the car away until i save the funds to take it to a shop and have the heads repaired/replaced with rebuilt units or slowly start tearing it apart myself with no set date of completion.

Was there much wear on the cam?

I know the 2valve motor has a oil restrictor, they will cause some noise if they clog.

ANYONE know if there is a restrictor on the 4 valve?


The noise isnt that bad. I would like to see you fix it, i listened to the noise again, it sure sounds like lash adjuster to rocker. All cam lobes good?

Yes, under the rearmost cam cap

[tbone]

This probably isn't it but have you tried removing the belt and listening? It's worth a shot...

Ill try to record another video today when i try to move it into the garage so you can have another (up to date) listen. yeah the cams look good from what i can tell. i may just remove the covers again and just redo the whole procedure again. i need to check whats causing the misfire under-load anyways

The Serpentine belt ? the noise is only heard at start ups or under loads

Bearings in pulleys sometimes make (more) noise under loads or when the load is removed. It takes 2 minutes to try it.

(After listening again it sounds like the noise starts as the load is removed. Removing the belt is the first thing I would have tried...)

I'll try that first thing tonight

Just recorded this if anyone would like to take a listen

It wouldn't hurt to add a quart of Marvel Mystery Oil to the engine ( yes it will be fine even with 6 quarts of oil in there already) and drive it 50 miles then change the oil.

I've also seen many times exhaust least causing ticks and these cars are no exception.

My son (who I thought I trained better that this) had 12 quarts in his Northstar DeVille and the thing still ran fine with no issues. I was shocked. And pissed as it overflowed my drain pan....
(He added an entire 5 quart jug all at once because these engines leak. :( )

That’ sounds a lot like valve train noise. Sounds like when my timing chain broke. I’d lift the valve covers.

[Chard]

Could low oil pressure cause this issue ??

[GetMeMyStogie]

+1

It sounds a bit like my MM, which has one or two broken manifold bolts. It doesn't bother me enough to have them drilled out and replaced.

Is your sound constant hot or cold engine, or does it go away when the engine heats up?

[MarauderOrlando]

Any update on this issue?
