Jerm Posted May 8, 2019 Share Posted May 8, 2019 Help with engine tick! 2010 fusion 3.0 v6 90k miles, original motor was replaced due to previous owner running it out of oil and it spun a rod, the new motor came from a junk yard who said it had 88k miles and the motor ticks/taps that sounds like a lifter, it is louder when cold and first started and gets more faint when warm, most noticeable when under a load (backing out of drive way) and the sound goes away once revved past 2500, if revved in neutral or park it goes away after 1500rpm. It also does it at idle only when cold, when its warm the tick is sort of periodic and much quiter. I'm assuming the motor had sat for while in the junk yard but what is causing this tick? Surely its nothing like a rod bearing with only 88k mile, it is a clean motor and has no oil leaks, I've had marvel mistery oil in it for the past 500 miles and it seemed to help a little, it runs fine but does seem to have a hesitation on medium acceleration kinda feels like a miss but no engine light, anyone else experience anything similar or are these just noisy engines? I know they have hydraulic lifters/tappets.. Note I do have 5w20 conventional oil with 1 quart of mmo in it, don't know if not running synthetic will have anything to do with it or not 0 Quote Link to comment Share on other sites More sharing options...
CarGeekIII Posted May 18, 2020 Share Posted May 18, 2020 I have experienced this with my 2011 3.0 liter. It began around 110k and continues at 135k. I've attributed it to a lifter problem. As stated, it does not seem to affect the running of the engine. For lube, I've been running Castrol Syntec 5w20 in the engine for quite some time. I was considering some Marvel Mystery Oil about 500 miles before my next oil change to see if that will clear it. On a related note, my Nissan Titan 5.6 liter V8 does the same thing. It began at approximately 80k miles and persists still at 98k. 0 Quote Link to comment Share on other sites More sharing options...
cmte_carvalho Posted January 18, 2023 Share Posted January 18, 2023 Hi! Have a look at these two videos both by Fordtechmakuloco/Brian - there's a chance they're related to the ticking noise: Take care! 0 Quote Link to comment Share on other sites More sharing options...
