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 the car is in no condition to travel anywhere like this.
I would appreciate any help to figure out the cause or a solution to fix the problem.
My car is a Volvo 850 Sedan made in 1993.
Thanks in advance !
Here are two videos to show the sound I'm talking about:

Re: Help needed with Volvo 850 engine popping noise Topic is solved
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.

Re: Help needed with Volvo 850 engine popping noise
Try removing the serpentine belt and seeing of the noise stops. It does not sound good, but could just be a bad accessory

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 go away if you rev the engine? Does it go away when the engine is warm?

Re: Help needed with Volvo 850 engine popping noise
Well, to be honest it's been a while since I replaced the components. But the ignition is working fine I checked it. It feels more like if something is jamming the engine.

Re: Help needed with Volvo 850 engine popping 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
It feels more like something is jamming the engine when it tries to roll. Sometimes it goes away when reving, but it comes back in idle every time. First I'll try to remove the serpentine belt this weekend, let's see if that helps.callahanoffroad wrote: ↑Thu Aug 29, 2019 6:28 amLook at how the engine vibrates when it makes the noise.

Re: Help needed with Volvo 850 engine popping noise
At idle a bad sparkplug or wire can actually lead to heavy cutouts in these cars. they usually start cutting out in humid conditions, but not necessarily. almost like the engine wants to stall.hunterhuni wrote: ↑Thu Aug 29, 2019 9:56 amWell, to be honest it's been a while since I replaced the components.

but then, maybe it is something with one of the accessories. before you remove the belt, look up on all the creative super cheap serpentine belt tools members of this forum came up with.

Re: Help needed with Volvo 850 engine popping noise
That sounds like crossfire to me. Cap, rotor, wires and plugs to get you to where it can be diagnosed. You may find that it went away when you do a tune up.

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.
Apparently it wasn't that big of a problem. Thanks for the help, and suggestions. Drive safe
