Ford Tech Makuloco now said that he will use the revised plastic tensioners?
I have some ticking in the first minute after the car was sitting for 5 days. Unfortunately, getting parts has become difficult to Germany these days.....

i thought it was the metal ones with the ratcheting wheel inside so no oil pressure still keeps the chain tight?

Apparently the ratcheting tensioners have been causing problems, so Fordtechmakuloco recommends using the OEM plastic non-ratcheting units.

Billet aluminum tensioners with the ratchet teeth filed away is what I am running. They are still spring loaded and pump up hydraulically just like the plastic ones but have an O ring instead of the sealing compound gasket.

I bought a set of the fel-pro gaskets that they make for the stock plastic tensioners. They look a lot more robust than that thin seal around the stock ones. They fill in the unnecessary cavity in the stockers with solid rubber and are less than $10 from rockauto. PXL_20221021_182127507.jpg PXL_20221021_182107599.jpg PXL_20221021_182154987.jpg

I thought I had some valvetrain or lifter noise last year, but it turned to be an exhaust header gasket leak. Granted I was using the header gaskets that came with the Kooks headers which I put on years ago. i didn't realize at the time the factory ones were best. So I replaced them with factory gaskets.

I have used those same Kooks aluminum header gaskets #PY-8023A-AL and never had any issues, set and forget them. I do spray them with hi-temp copper seal (old racers trick) prior to install.

I have similar noise. Now in process of replacing timing chains, guides, tensioners, phasers, rockers & lifters. It would kinda suck if I did all this and it's just a header gasket leak, lol.

Not really. Think of it as future proofing the engine. :D

Yeah, basically that's my thoughts too. The job is taking a lot longer than I expected, so I'd rather spend a few extra bucks and get all new, good Ford parts, in the hopes that I NEVER HAVE TO DO THIS AGAIN! o_O

Exhaust leak wouldn't be coming from the valve covers. i assume you actually put something to the valve covers then to your ear?

Well, never 'assume' anything, haha. I actually was driving next to assorted walls and listening to the reflected noise as I was putting different loads on the engine. After a few minutes of that, I was convinced it was a broken timing chain guide, thus my adventure began. Upon dis-assembly I immediately see that my initial diagnosis is 100% wrong. So now I am left to try and eliminate anything that might be causing that ticking. And since it is apart, I feel like I have no choice but to fire the parts cannon at it.

I am going to remove the cams and remove/check each valve spring for correct tension. Plus I ordered new Viton valve seals, in addition to everything else listed above.
