Loud Ticking noise

[Noel69]

I have a 2003 UZJ100 V8 cruiser which has developed a loud ticking noise from I think the R/H/R of the engine. I have done a valve lash and compression check and both seem ok (with-in spec)
I Believe that it maybe a lifter but not sure. What happens to a lifter to make it faulty?? as they are not hydraulic lifters. ( fed up with people saying "oh you've done a lifter")
What else could be causing the noise?
Can the belt tensioner fail causing a ticking noise?
Can i check the valve lash with the engine running by placing the feeler gauge under the cam lobe to see if the noise stops to pin point the one at fault?

Any info would be great

Hi Noel,
you might try to pinpoint the noise. Put the blade of a long screwdriver against the suspected area of the engine and push your ear at the end of the handle. The screwdriver will act as a stetoscope and you can 'listen out' the engine.
if you run the engine without the camshaft cover, you're in for an oil shower. Putting anything between a camshaft and a valve while the engine is running, seems like a very bad idea.
good luck,
Wout

Thanks Firewout...
I have used a stetoscope and had the rocker covers off and managed to put the probe of the stetoscope on the side of each lifter as it was running and still could not pin point the area. I have been told it could be a cracked exhaust manifold but I'm not 100 percent sure that is the problem.

Have a listen to the fuel pump and around that area as well.

cracked exhaust manifold(s) is a very common cause of a ticking noise on the UZJ100

One way is to upload it to youtube and then post the youtube url on the forum.

See the options above (when your typing) Bold , underline , smileys etc the second but last option , a box with a tree in it , click that to upload pics and vids from your computer to the forum . 3 years i've been using this forum and never knew it but don't tell the mrs who worked that out on her very first post

Tap the tree icon choose upload browse to the vid file and after selecting it you get a video panel showing, top right it says "use", click that and it compresses the vid, and then upload.

I did this one from my iPad....

I'll try that now.
No go, I get 'invalid file'

I have this and can say it's very annoying.

yeah i went to the advace setting and it takes ages to upload but then I cant see it anywhere....some is getting a heap of videos of a ticking engine...LOL

 

[Noel69]

Can anyone tell me if it is a lifter making the noise.... how will i find out which one it is?? will the valve lash be excessive on the faulty lifter?

 

[nathanrobo]

Just a thought, but is the noise constant? Is is worst when the engine is cold, especially when you first start the car?

 

[frank rabbets]

A cracked exhaust manifold will be louder ticking with engine on wider throttle and under load. A faulty lifter will be constant.
