New to me 850 turbo sedan Topic is solved

Step back a bit and think basics and don't get lost in the possibilities. After warming, unplug each wire from it's designated spark plug and listen for arcing, see if car runs obviously on one less cylinder. You may have done this. Then as suggested in other posts go directly to compression test. But does the car start and warm up just fine? Bad coolant temp sensor can really be sneaky. Go to compression testing early. Doesn't cost anything, and you have immediately ruled in or out worst case possibilities. Otherwise one ends up tossing parts randomly, angst in attempts to fix, etc. Walk it back from your compression results looking at fuel, air, other when necessary. Just my approach and I am no expert. Maybe someone said this already.

another cost is you have to have a second car to use while you fix the volvo. thats a deal breaker for most due to limited budget for insurance or parking space. Also it helps if you have space to keep 2 or 3 spare parts cars.

Wtf are you doing to your cars, dude??
I’ve never had a second car or needed one, and I don’t have 2-3 parts cars sitting around either.

Knock on wood, but I’ve always been able to fix my 850s in quite short order, and never but once had it to a dealer to fix something (worrying sound, which the dealer mech fixed with a damn crowbar... )

Sure they’re heavy, sure they need attention, but you don’t need 2000 dollar dealer servicing, you can do most things with a few screwdrivers and wrenches, and if you give them a shower once a week in winter, they don’t rust either.

If you buy a clapped out Volvo , 20 years old, young will spend 2-3x acquisition cost putting things back to where they need to be. Two out of my three were bought at clean retail prices , well maintained,And have been good daily drivers with a total of three breakdowns in 25 driving years. The third was purchased somewhat below retail , well maintained, and will follow suit.

I was exaggerating a little for humor, but if you are doing any mods or cumulative maintenance combined with getting parts mail order
the car will definitely sit. Its nice to take it apart first and order later as you never know what you need or not need. Around here there is no dealer and except for oil changes you wouldn't want to use Napa for volvo. So you can order in advance but that means a lot of parts you dont need to cover every possible problem. For instance changing the heat core, I bought a firewall hose kitt in advance but turned out mine was fine. The core turned out to be new too, but not heating air due to being aftermarket design that allows air circulation on the sides that do not fill out the space in the air box.

You don’t refurbish by just replacing broken parts. That’s firewall kit has four o rings in it which you just rolled when you pulled the heater hoses. On a 20 year old car, you replace the Orings and I replaced the bulkhead piece too.

The foam gasket in the heater core is part of the kit inOEM , aftermarket parts look cheap but short you on things like this. The difference in fit and function between aftermarket and Volvo parts is usually profound.

The supply chain in VAG group is horribly corrupted with bad parts. Volvo is much better.

I hear you. I've replaced the thermostat of my friends 2002 Ibiza four times in the last five years. Well, you could say that I'm a bad mechanic, but it's made of plastic and the thing just breaks after a year.
