day together, today I need your help briefly. before a few weeks the car started to jerk during the ride. after I first thought about steering gears / servo steering, I checked my candles last weekend. to the engine: – 2.4 turbo with 193 hp – gas system is installed were 5x original volvo candles – built for 1.5 years, about 20,000 km ran. here the picture after the expansion. candle nr. 1 is completely burned down. https://data.motor-talk.de/…/previously-1-8971023 240380644574.JPGhttps://data.motor-talk.de/…/vor-2-4085480412888067314.JPG because I had no new candles to hand, I installed an old candle from the last change (bosch – see candle nr. 2.) the second candle (volvo) I screwed in for the burned nr. 1. the engine started super. after 5 km however started the jerking again during the ride. so I got 5x new original volvo candles for the turbo and built them this morning. here the picture after the expansion the candles that were now 3 days in the car: https://data.motor-talk.de/…/after-1-6724032011755817824.JPGhttps://data.motor-talk.de/…/after-2-8096641682161302121.JPG asks: – why is kerze nr. 1 (previously nr. 2) so oiled after 3 days? – why are the interiors 1-4 so clean and nr. 5 so brown smeared?https://data.motor-talk.de/…/after-nr-5-297477641154540314.JPGhttps://data.motor-talk.de/…/cable-8754308472746573478.JPG to explain: – the compression I had Saturday with g etestet. nr. 1-5 all ran out to 14. parallel: – since a few days the car loses cool liquid. times 1 liter on 5 kilometers during the trip. sometimes nothing. – sometimes the container is full in the evening and in the morning when I start to work completely empty (over night, during parking) – Saturday I gave pressure on the system to check where the water leaks –> result: it did not occur anywhere. at least not the 10 min. where the test ran. add: – four weeks ago 40 0ml oil from the servo container and the steering made funny noises. after filling the oil everything is fine again. now I’ll see how he does himself with 5 new candles and reports tonight. does someone have an idea what the volvo lacks?
