Hi all

I have a 1995 volvo 850 t5. Well, my partner has one and id away at the moment so I am hoping I can delve into the issue a little before he gets back.

Basically, the engine is making a clicking sound. Immediately on start up, which continues when i drive. In saying that, ive been only doing 5 minute drives so perhaps its not running long enough to go away.

So today, i started it. Car starts ticking. The ticking is like 3 or 4 seconds apart between clicks, and the idle seems to change slightly each time it clicks.

I checked the oil and it was a little low. So i put 2 litres in, and then i ran the car (idling) to see if it would go away. Just for a few minutes.

It did seem to go away, but then i gave it a little rev and it came back.

So in summary, clicks on start, idle and while driving. Idle changes slightly between clicks. And there is a few seconds between clicks.

Anyone got any idea what this might be? And is it fatal?

I need to do a 200 kilometre drive on monday and i dont want it to poop itself

just checked it again. If i leave it idling the click stops but as soon as there are more revs, it comes back. And the noise is almost like the click of a switch (like when your kettle finishes boiling and the switch flicks off. Not the best comparison but similar lol)

Thanks

 

If it's the lifters it might be your choice of oil filter. Please don't use Fram. If you have a Fram on it now, replace it.
Many people, myself included have run into noisy lifters when using Fram filters on the 850s.

 

It would be best if you could post a video and get close to the sound. If the idle changes, it is likely some sort of air valve or vacuum valve going bad.

 

Thanks for your responses.

Ive found out it is the aircon. The noise is coming from where the ac clutch is.

Turned the ac off and the noise has stopped.

 

So it's cycling off and on? If so, it likely needs serviced.
