The tappet noise is common on the early 2.0 litre engines on which the 2.3 is based - it was cured on the later models with a modification and is quite normal - the only reason it was fixed was due to owner worrying about the noise - It will come and go as the car warms up - I've two that have done it and both have been fine in every respect.

I have just purchased a 94 850. When it's under and hard acceleration it makes a buzzing sound. Also I have to hold the shift knob to keep it from slipping between gears.

Any suggestions?

I have a 95 Volvo 850, and if your 850 is driving rough, hesitating or shutting off when you come to a stop, change your Throttle Position Sensor and your Oxygen Sensors. When I got my sensor changed, the old one had oil and crap all caked in it, which caused the car to drive like crap sometimes. You should notice a huge huge huge difference afterwards. It is a great car, but for some reason, as age hits, the different sensors start to breakdown. You may think it's a major part like your engine or transmission, but it could just be something as simple as a sensor that needs to be changed.

I have a 96 850, and while pulling into gas station, I shut it off like normal. However after grabbing my Coke and Doritos, it would not start. I tinkered on it and tapped on the fuel pump cover; it started. Coincidence? Anyway, I fortunately got it home and pulled into the driveway. Now it turns over, but will not start; the same as before. I've just replaced the fuel pump. Same problem, now what?

Thanks for great site! Paul.

I just bought a 94 Volvo 850 from an auction. It leaks power steering fluid, oil and I just replaced the axle and control arm. There is whining noise, so I know it's my power steering. I was told to replace the rack and pinion (700 repair). What could the oil leak be?
