Hmmm by timing set do you mean including the phasers as well? Or just the chain?

Phasers, chain, tensioners, guides, sprokets, oul pump, and water pump while there. All went well during install (ref fordmarkoloco youtube video for assistance, dude is awesome). Of course new gaskets all around and VCT and seals.

Sorry just to clarify, the timing set was cloyes so like the phasers for example were not Ford OEM? In which case it's always recommended to go OEM on the phasers. That knock is exactly what I have with my Ford phasers, it's a relatively "normal" sound of the VCT system. Guessing it only does it during when the engine is warm? There is a TSB out on it and it's the "hot idle knock". More of a sound annoyance. Basically the locating pin inside (that locks it at base timing during idle) is knocking around in its hole because there is no thick oil flowing around it. So it's echoing around, usually meaning it's worn. That's why I asked if the phasers were OEM. Ford's won't make that sound if it's brand new.

i sincerely appreciate the replys!!!! Those were OEM fomoco phasers installed from “Freedom Racing”. All parts except for the Cloyes TC kit and melling 360 oil pump are OEM. I had a mechanic tell me it was lower end but if so it should make the noise all the time. Yes, it only does it after its warmed up and has been driven. I let it idle after cold start for 20 min and not a sound. Here is a link to another video i did tonight. Thanks again for the help.

Hmmm the second video doesn't sound like what I have nor what FordTech was showing. Now I'm starting to think it could be something else especially since the noise disappears in certain gears. Perhaps someone else could chime in, otherwise I'll probably be looking into this in the morning

May I make a humble observation. Bare in mind that this entire system is dependent on proper oil pressure/flow. The first diagnostic I would suggest for this issue is to check the actual oil pressure. In my case, I found a bad seal on one the tensioners. That in turn created a lack of pressure/flow and the system did not perform properly. The tensioner could not keep the chain tight causing a failure of the guide rails and further problems. I did replace the entire system but feel the phasers, chain and sprockets were fine. Since I paid less that $150 for the entire kit plus oil pump I am very happy with the results. I drive my truck quite alot and have put close to 20K on it since the repairs. She is quiet and purres like a kitten. I have installed a real oil gauge and at 200k miles can report a hot idle pressure of 30lbs.

thanks for the input! I have used a stethoscope all over the engine, if the chain tensioner had failed i should have been able to hear that on the TC cover right? I am getting Nothing on the top side or the bottom for that maater. U can clearly hear it when under the truck but I cannot locate it. Ive told it could be crank bearings, but i would think i should hear that when scoping the oil pan or the block? I admit im not a savy mechanic, ive not done this stuff in 20 yrs. due to technology i feel left behind a bit. Also, I admit i have not put a guage on the oil. This is something i will do. Thanks again for the feedback! Trying to rule out crank bearings. FYI. 121k miles on truck. 5W-30 oil mobil 1 w MC oil filter. Changed every 3-4k miles. When phaser n such changed there was no visible sludge, all looked clean. Cam was good and lash adjuster rolled freely.

Whether the 260,000 is km or miles, you probably could - BUT I WOULDN'T. A new tensioner with plunger fully extended probably would still leave the chain loose.


The chains WILL be lengthened by wear / stretch with that many miles. Basically, THAT is the purpose of the tensioner in the first place. If chains never stretched, you wouldn't even need tensioners.
