Engine noise Hello I just purchased a 2005 lincoln navigator and took it to a Ford dealership for a through inspection.My suv makes a ticking noise and they said its a camshaft phaser : necessary adjustments include(lash adjusters,camshaft gear / sprocket. just wondering how expensive if it is that would it cost......I took it to another mechanic and found the engine oil level low by about 1.5 litres and dirty ...we added new oil 5w20..his concern was it may be burning oil..looked at the oil level after 300 kms again and seemed to be ok was worried about the oil i need to be concerned about the ticking noise ?.. i hope this all makes sense to you.. regards R

    1999 Navi makes same ticking sound, isolated it at passenger side rear cylinders. Sounds like a solid lifter noise. Is this something common or do you let it go? Should this be addressed? Previous owner told me about it prior and said it had been making sound for some time. I thought initially that it was an exhaust leak before I drove it.

The ticking may have been related to the low dirty oil condition, did you get proof of regular service? the engine in your truck does have some history of oil consumption problems, but I think by 05 they where fixed by Ford, the ticking is either the cam chain or the cam followers, never heard anything called a camshaft phaser, and I have worked for a Ford dealer 20 years. Abnormal oi use is anything over 1 quart US for every 1000 miles of driving, a little more if you drive in hot weather conditions. Put a can of Berrymans Chemtool in the oil, this may help to clean the inside of the engine, also make sure to run either 10-30W or lighter in the engine, heavier oils will cause bearing damage.

yes, but if you look under your hood, you should be able to narrow down where the noise is coming from in that large engine compartment. also think about replacing the belt tensioner as well since you are replacing the belt with the idler pulley. its good preventative maintenance!

When I get up to about 65-70 mph with my 2004 Lincoln Navigator it makes a humming noise... very annoying.. Can anyone help me with what this is and how I can get it fixed?

Unfortunately, this is a somewhat common problem. Ford has issued several Technical Service Bulletins related to rear end noise. Without an extended warranty, this is something you will have to pay for.

Some vehicles may exhibit an axle whine or hum during acceleration, deceleration and/or cruise.
ACTION: An axle repair kit has been developed which incorporates most parts required for a comprehensive axle repair. The kit should be used instead of installing a complete axle assembly to repair an axle whine/hum. Replace Ring and Pinion with Axle Kit and Components.

The engine seems to be making a sputtering noise

Amelia, we just bought one off a lease 5 weeks ago (purchased from a dealer). We are having the same symptoms, suddenly, as you describe.

Took it back to the dealership. After a bit of drama, they agreed to foot the repair bill ($1000). It was a broken distributer cap and wiring which should have been replaced before it was resold to us. What a pain.

Engine noise

You have the 5.4 3 valve engine in your Navigator, Ford has had various problems with noise from this motor. The cost of repair will vary because this noise cam come from different places, such as cam phasers, valve lash adjusters and sometimes the ticking noise is actually coming from the injectors which is considered normal. I would have it checked out by the dealer. -Jared
