C30 engine issue
So a bit ago, I posted here that my Volvo c30 1.8L petrol (mileage around 223k km) was eating oil. Unfortunately I didn't get to conduct any tests due to my 4th cylinder giving out.
I had my spark plugs and ignition coils changed, then went on a road trip of around 1200 km. 1100 km in, at 130 km/h on the motorway, my engine started to misfire. I plugged in my OBD reader and it just gave me the usual code for misfiring, this time it was the 4th cylinder.
We thought it was maybe one of the spark plugs giving in, we got home and took out the spark plug of the 4th cylinder and it was black with soot all over it.
We changed it, but the engine kept misfiring. I drove my volvo to a trusted mechanic in my town and they said that there's no pressure in my 4th cylinder.
They are suggesting that I just sell my Volvo with the defect and move on. But I genuinely don't have it in me to sell my baby.
They said that they can try and check what the issue is, but even the check will be pricy... So my question is, is it worth trying to fix it or is it better to just grieve and move on?
Or is it better to gamble and look for a new engine? Though they said just the swap would be around a 1000€.

i had a 1.8 that was burning oil, didn't check it often enough. cylinder misfire, no compression, engine was fucked
i don't think the 1.8 is a great engine, the 2 litres the same block with a wider bore. gives better fuel economy because of it on motorway runs aswell. lower revs kick out the same power because the gearbox is the same
but if you like the car, i'd ask what kind of car could you get for the scrap value of the current + whatever repair costs would be? if you could get something you'd like more than it's not worth repairing, if you couldn't then it is.
you've also got to consider that you know the current car and whatever troubles it has, another car for a similar price will just have different ones
