IDLES ROUGH AND STALLS WHEN WARM OUTSIDE


Check for broken breather hose from valve cover and follow it under the intake. You may also have a ruptured diaphragm crankcase ventilation valve (vac leak), bolted under intake manifold.

Volvo v50 t5 oil leak


Most likely it is the breather tube and/or the oil trap box (integrated into the oil filter housing). if the box is plugged or the diaphragm is torn the box will send oil to the top of the engine via the hose.

do you also have a high pitched whistling noise?

Volvo has extended the warranty for the oil trap box (filter housing) to 120k miles and/or 10 years.

745 bmw il 2002 idles rough


This is usually caused by the crankcase vent valves leaking air. These valves are round and sit on top of the front of each valve cover at the front. The diaphragm leaks and causes a vacuum leak and the car runs rough.

I am experiencing a squeaking noise from infront near the fan belt area. when i accelerate,it gets louder. I discovered that the power steering pump is leaking ,so i topped up the reservoir and it stopped...


i have a similar problem. a squeaking noise, sounds when i start the engine, and when i stop the engine. at times it comes when the engine is running and idle, and it lasts some time like a high pitched whistle. Ive had several mechanics look at it, and it seem to be one of the smaller pulleys that the belts run around. in the 2002 model (petrol) of the crv the belts are not the cam belts, becuase this model has a cam chain (much more robust!). so they all said its nothing to worry about. you can try having your pulley replaced.

1987 bmw 325 idles rough


On the 325 series I have worked on (your year, make, model), I have found that idling issues like you describe are the result of a defective oxygen sensor. Replace the oxygen sensor with a Bosch unit. That should take care of your issue.
