Sewing machine under the hood

Watch the video i posted?

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

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

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.

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.

Speaking to this...

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.

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??

Zinc additives are not good for Cats!!

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.

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.

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.
