Default Ford Fiesta 2012 LX Engine tapping noise

I have a Ford Fiesta LX 2012 (154,000k on odometer) that has had a loud tapping noise coming from the motor. It has the 1.6L Petrol engine, but the tapping makes it sound like a diesel.

The engine starts first time, it does not use water, or burn oil and it has not any oil in water and vice versa. I am experiencing no warning lights.

The only real issue is that it is quite sluggish when the air conditioning is on, and in summer it feels sluggish and intermittently stalls while idling, but it starts straight back up. The colder the weather the better the engine runs.

I had a mechanic look at the issue and they have told me that the engine needs replacing because it is worn out.

I'm tossing up whether it is worth replacing the motor, or if I should get another mechanic to take a look in case it is something that can be fixed without replacing the motor.

Has anybody else experienced this type of issue with your Fiesta? and if so, what caused the problem?

What fuel do you use?
I had one of these-It just did not like 91 esp on hills with air con on.
If you run 91 run it on 95 see if it goes better.
Yeah I would get another mechanic to look at it. even if the engine is tired you can probably still get another 20000kms or more out of it.

Tapping or more of a knocking noise?



18 seconds onwards, does it sound like that?

Thanks for your replies.

I'm running the E10 fuel in it (Ethanol). I've added Super premium (98) to the tank and will refuel with that next. I will get another mechanic to also look at it. I also checked the oil levels and made sure it was full (It was halfway between empty and maximum). The engine is at it's loudest until it warms up, but not so loud that you can hear it over the radio while driving.

I've recorded my engine, it sounds really loud and to be honest quite knackered. It sounds similar to the video that you posted as a reply above.

That sounds like noisy/sticky lifters to me, usually rod knock is deeper, has it always been serviced on time or has it skipped services?

I'd be putting an oil flush through it, I've always been skeptical on this snake oil bull**** until I saw one work to clear up lifter noise on an abused old EF Falcon, it cleared the lifter noise after idling with it in the oil for about an hour.



This is the one you want - Purge-EF EF-850 by Fuel Treat Australia,

You can contact them by their website:

https://fueltreat.com/contact-fueltreat-australia/

Its not available over the counter at parts retailers, they primarily sell to OEMs.

You might need to buy a carton of 24, or maybe see if you can mix and match a carton of 24x with a mix of Purge-EF EF-850, Surefire FI-700 and Freerun FR-788 and then do all three on the car.

Put the Purge-EF in the car, let it idle in the driveway for an hour and then drop the oil, remove the oil filter, replace with a new one and then fill the oil with fresh oil.

I've got no affiliation of Fuel Treat Australia, but I have used their products and I've seen it clear up lifter noise on some absolutely abused ****boxes.

At most even if it doesn't work and its fingered, you'll only be down about $200 for the Surefire EF if you have to buy a carton, if its just sticky lifters then you got out of this cheaply.

EDIT: If you want I'll post you some free of charge, I have some on hand, that way it costs you nothing, private message me a postal address and someone to address it to.

Thanks Franco for the fantastic feedback and advice.

The Fiesta has been serviced regularly and I make sure it has oil in it. I will order some of that oil flush today and give that a go.

Thanks once again to everybody who has given advise. I appreciate it.
