Why is my engine chattering?
An engine ticking noise might seem fairly normal, but it could be an early sign of low oil pressure. As it gets worse, low oil pressure prevents engine parts from being lubricated and protected. It doesn’t take long until it gets much, much worse.
How do you fix a rattle valve?
How to Eliminate Engine Valve Noise
- Check the oil level in the engine; a level that’s either too low or too high can cause valve noise.

What are the most common problems with 1993-2000 Volvos?
All 1993-2000 850, S70, C70 and V70 models (as well as most 2001 2007 S60, S80, V70 and XC 90 models) use a complicated crankcase vent system to prevent the build u of pressure inside the engine. Since the mid 70’s Volvo owners have had problems with this system clogging up with oil deposits.
Where is the dual exhaust outlet on a Volvo 850?
For example, my Volvo 850 now sounds much deeper and more refined. A “dual conversion” will be for those that have a single pipe and want a dual exhaust outlet. The majority of the time, this occurs right at the very end of the exhaust stream, so it makes little to no performance difference.
What kind of exhaust system does a Volvo use?
As for emissions, as long as you use a certified catalytic convertor, run both O2 sensors in the stock locations, and a silencer that silences enough, you will meet all emissions and sound level laws. Like I said, I have a 3″ downpipe back system, and I have yet to throw a light.
What’s the problem with my 1993 Volvo 850?
Just the little annoying things that can drive you nuts trying to resolve if you don’t know the cause and where to begin fixing it. Beginning with the 1993 850 Volvo began using an upper engine mount (also called the upper engine stabilizer) that helped to control engine movement especially during acceleration.
