is it the injectors?

[MGM]

hi guys, ive had a ticking sound coming from the engine bay for a while now, its real loud, i can hear it when driving next to a wall or barrier. the car still runs fine but i hate the sound. makes it sound crap
would it be injectors? is it bad to have them doing it?

[howesy]

Didn't look but if it's a v8 then more than likely the purge valve which is up in behind the near (passenger) side guard. Fords technical fix is to access the area and bend everything up and wrap a rag around it but be careful this is a highly technical ford skilled operation.

yeah its the carbon cannister

nah its not an 8. just an xr6 ute <<. im not sure if the sound was there when i bought the car 8 or so months ago but i hate the sound. can it be the same problem being a 6?

[JOSH]

well it might be a lifter then, how long ago did you change the oil?

[MGM]

ive changed it twice in the last 8 months. last one was 2 weeks ago, had the sound before i changed it last time

yeh mate mine is the same......just had injectors serviced.....mech said it was lifters...replaced them all.....still there after 3000kms....changed fuel pressure regulator stopped for bit then came back after 4 hour trip....got told it could be the map sensor....still havent changed this

[MGM]

thanks mate, i want to find out what it is coz it sounds crap

[MGM]

got my extractors put on today and it seems to have made the ticking louder. when i looked under the car it kind of sounded like it was from the cat/gearbox to. unless the sound travels through the extractors somehow

[HLC]

itll be an exhaust leak.

i have the same ticking. tightened all my header bolts. made it better for about 10 minutes, and now its even worse.

Extractors do make a ticking noise of their own.

Perhaps the noise you had previous to their installation was the timing chain. It is known to rattle, mine drives me nuts. The tensioner is hydraulic IIRC.

Try a different viscosity oil and see if that helps. I've tried 10W/40, 10W/50, 15W/50, all with varying degrees of success and next time I just may try a 10W/30. It's trial and error.

All the best with it.

There's no valve clearances to set, the tappets are hydraulic also.

yeh mate mine does the same....only when its warm to..not when its cold....put the screwdriver to ur fuel rail....mine comes from this area....mine have gotten louder since the extractors got installed...pacey comp header....4480????

[MGM]

i got the 4499's cheap off a member on here. the extractors were louder yesterday with the ticking than today. but i thought it was mabey the injectors as it didnt do it when i bought the car (i think)

Have you tried to isolate the noise with the old "long screwdriver handle pressed to your ear, then touch various parts" trick?

It can be staggering how well that works

[MGM]

no i havnt coz ive never heard of doing that but il give it a go tomorro. thanks mate
