Ticking Noise from engine 850 95

posted by  someone claiming to be Hack-Man on  Sat Mar 31 07:23 CST 2001 [RELATED]

I have a N/A 850. In the last day or so, I've noticed a light ticking noise when the engine is first started. It seems to go away after a few minutes. Anyone have any experience with this?

Thanks,

    Hack-Man-

    This sounds like a lifter noise. As long as it goes away within a few minutes, it is not a major concern. If it comes and goes after the engine is warmed up, it may be a sign of lifter wear/failure. How dirty is the oil? You can try changing the oil and filter and running the car for 10-15 minutes over 5000 RPM. (Second gear on the highway) Don't worry- as long as you have oil and coolant, and the T-belt isn't overdue, the engine can take it without any problems. If it lasts longer than a few minutes at startup or comes and goes after warm, you can replace the lifters. The replacement parts from Volvo are an improved version that specifically addresses the noise concern.

      Sounds like I may have the same problem. The ticking sound seems to come and go and when the car is hot or cold. What is involved in replacing the lifters? Can you give me a ball park estimate or is this a do it your self type of job?

      Thanks!

        Jeff-

        This is NOT a job for the DIY! The upper half of the cylinder head has to be removed to access the lifters. During this procedure, there is a risk of damaging the thrust flanges in the head that control camshaft end-play. Also, the PROPER way to re-assemble the head involves Volvo special tools to index the crankshaft and both camshafts in the correct postions to verify the cams are timed correctly. (the cam sprockets are slotted at the bolt holes) It takes about 5 or 6 different special tools to do this job- the cost for the tools would be at least a few hundred dollars for a job you probably won't ever do again. I estimate the labor to replace lifters at around 8 hours for a professional shop with all the proper tools.
