Re: Help needed with Volvo 850 engine popping noise

Okay, I managed to figure it out. I changed the head gasket, and two of the wires that go to the spark plugs. Two of the engine cylinders weren't working because of that. Now it runs like butter.

Re: Help needed with Volvo 850 engine popping noise

Look at how the engine vibrates when it makes the noise. Is that knocking/misfire? Burned valve? It doesn't sound like piston slap. Could be a weird sounding rod knock. The serpentine belt is long and it takes several rotations of the engine for it to hit the same point in the belt. Does the noise ...

I will try it on the weekend, thanks for the suggestion. Hopefully it's just a bad accessory somewhere.

Re: Help needed with Volvo 850 engine popping noise

Sounds horrible. could it be bad ignition components? when did you replace the wires, plugs, rotor etc.? Also, the startup sounds creepy as well. Which would make me think of the ignition as well. Well, to be honest it's been a while since I replaced the components. But the ignition is working fine...

Help needed with Volvo 850 engine popping noise

Dear community Recently my car's engine started to produce a strange popping, crackling, clicking noise, whenever I start it. After a while the engine just stops, especially if the air conditioning is also turned on. This noise kills the engine. I'm really not sure what's causing the problem. But th...
