Have your oil pressure checked, Is the engine clean inside, if its gunked up, the oil pickup tube could be clogged.

Engine problems


intake valves on the R side of cyl.head.exhaust valves on L side looking at engine from transmission end. need to perform a compression test on each cylinder making sure that the psi doesnt vary by more than a cpl. psi between cylinders.FUEL INJECTOR is very likely.AND injectors make a clicking noise when energized.a click each time injector is pulsed.(thats each time the cylinder is fired=alot of ticking or clicking)the higher the rpm the more rapid the noise.injectors are on the intake side of cylinder head. opposite side from exhaust manifold(the manifold that your tailpipe attaches) unplug injector on no.2 cyl(if thats where your misfire is) while the engine is running, if the engine runs the same without staggering or stalling there is your problem. good luck and happy motoring ___O^-o

A ticking sound on a 06 ford f150 super crew 5.4L


Ticking sound could be coming from a Coil-on-Plug, or a pcv valve, or (hope it's not) a valve lifter which could be sticking. Sticking lifter noise often disappears when rpm's change, or the noise comes & goes. try changing the motor oil & filter right after adding an Engine-Flush Treatment to the motor oil, running the engine for 10 minutes at idle with treatment added to the oil, then draining the oil & changing filter while oil is still very hot. That last part is very important, so be careful not to burn your hands - be careful. -- The sticking lifter is a likely cause if motor oil has not been changed at frequent intervals in the past (every 3-4K miles) -- dirty oil causes sticking lifters.

2006 BMW 3251 loud ticking sounds from engine


this is a very common issue with any of the bmws with n52 and n52k engine,as long as oil level is ok and is being changed regularly than than a "blleding proceedure" may solve this problem, when the engine has been running long enough that it is hot run the engine at idle to 4500 rpm for 10 to 12 min to start, if is still present after this attempt again.It has been said that this could take up to 30 min at longest.The reason for the ticking noise is a very tiny air gap in the hva and or lifters, try this and if does not work than the lifters should be replaced, although this noise doesnt really hinder the performance it does take away from driving such a nice car and having a loud noise come from the engine, good luck

2006 F-150 Triton 5.4 Engine -- ticking sound at idle on the top of the motor. Is it a phaser or injector problem? Does it need to be fixed? I just bought the truck 50k on it.

2003 Ford Ranger ticking noise, not a ping or knock. It is coming from the engine.


THE ticking noise coming from the engine ..is it just a 1 tick on idle at about each rev of engine,,and does it make any differance to the running of engine ,,Does it get softer when it gets warmer.
As it sounds like a loose tappet and being a oil adjusted tappets this thought of thing does come in now and again. and the best thing to do is to get a small plastic tube 25mm (or 1' ) and 2ft long and put it to your ear and listen at the top of the rocker cover ans see if the noise gets louder in a certen place ,as you will hear it if it is there..
Other wise it could be a Small end on the conrod which the piston is connected to.... lets hope not.
So let me know as soon as poss the answers to all the above. Ron

2001 FORD FOCUS LOAD TICKING NOISE


it very well can be that depending on the severity of the ticking noise, if it sounds like its coming from the top of the engine, place your hand on it only when you first start it up and if you can feel it knocking slightly and if the noise dies away once warmed up id say its your lifter, if its a heavier knocking rather than a ticking and comes from below or bottom end of engine it may be big end bearing, not good. try putting some engine treatment through the engine oil and make sure you run it in as directions state then change the oil and filter and see if that helps :)

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

I need help badly.


Good Day,

The shaking can be caused by a bad motor mount, but could also be caused from the engine when it is idle'ing low and about to stall. The motor mount would also shake the car under braking, so if is doesn't shake whiIe your braking it's probably not motor mount, Is your check engine light? The idle air is another possibilty among other things. I can assist further but I need to know which engine you have the 4 cyl 2.0L or 6.0 cyl 2.5L?

Let me know about the check engine light aswell.

Hope this helps
