Clicking sound dependent on acceleration, EF Sedan - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Hi all,

have a clicking sound under the hood like a bike chain clicking which is proportional to how hard I press the accelerator, and is independent of whether I'm in neutral, reverse or drive. In idle it clicks about twice a second, and when I rev it up it gets up to many times a second. Occasionally it will 'miss' a click. It happens in all gears and on both LPG or petrol. The sound seems to be coming from the engine block. The car (Ex-cab EF) seems to be driving fine and at full power. I looked up similar posts on this website and on the net. Can anyone please suggest which might be most likely or any other possible causes?

Possible causes and solutions:

- Spray pulleys, belts with WD40 - done, no difference

- Gudgeon pins - I couldn't work out where these were using my manual, given where the sound is coming from and its characteristics is this likely?

- Check drive shaft - did this, sound doesn't seem to be coming from it

- Charcoal cannister on passenger side might be touching body work - couldn't find this but it didn't seem like the sound was coming from that side anyway

- Engine mount flexing causing sound - the engine is very stable and sound did not seem to change at all when I supported it or tried to suppress movement.

- Check idle solenoid - seemed to be working alright, although I didn't
have time yet for a thorough check - is this a possible cause?\

- Try engine oil flush and then thrash the car - just had a comprehensive service and the engine oil is full and seems clean.
- Other possible causes - timing chain, internal engine part?

Thanks for reading,

Draco

Heya,

i had something similar, turned out the serpentine belt was dirty (i.e. full of dust etc etc). Let the car idle, and while the belt is going round, hold a brush to it, that should clean out any crap caught in it.

Hopefully it helps, and if it's not that, check your fuel lines as they could be touching and making the same sound.

To me it sounds like teh Purge valve on the charcoal canister return line.
Mine made a similar clicking a while ago.All i did was take it out, blow and suck it a couple of times and it stopped.

Sounds like the torque converter bolts have come loose & are hitting the engine block. If you can get under the vehicle, remove the inspection plate & check them. There are four of them.

Well, took it to my mechanic this morning and the problem is one of the lifters, we tried a hack fix by putting in a thicker drag car style oil, but it didn't reduce the noise at all, he reckoned that it was alright to drive on for a while as long as I could put up with the noise. I got a price for getting the lifters replaced - $640!!! (haha) inc. 2 1/2 hrs labor, how much can I get a new set of rockers for - if I can get them reasonably priced then I can just pay them for labor.

I picked up a set of lifters, brand new Dynotech brand, from the local engine shop, cost me $180.
And if you can do them yourself, you will be able to save heaps.

You may be able to clean offending lifter or just replace that one...Iff it is the lifter ?? It maybe due to excess clearance...
