I am the proud owner of a 2006 Volvo S40 that I picked-up from my mother about 2 years ago. She bought it used and with only 75k miles in 2016, it seemed like a great daily driver for our commute. It has been great but now, we have a problem. The car is physically in awesome shape, looks like it is a couple of years old in and out but we have an engine issue.
Long story short, I took the car into a local/non-volvo service shop to have the timing checked as the car seemed to be running slightly out of sorts. Car always started on the first try but would be a bit more sluggish than the typical 2.4i automatic S40. No odd sounds either and no other issues with the car. After the shop noticed the timing was off by a tooth or two (after the timing belt was changed a few thousand miles ago by my father and I, we also changed accessory belts and pulleys & tensioner), they corrected the timing and stated the car was running great.
Within 5 miles of me picking up the car, the car stalled in the road. Had it towed back to the local shop who did the timing adjustment and they claim that the AC compressor seized, snapped the accessory belt to the AC compressor (only 5k miles old) and a piece of it went into the timing belt/crankshaft causing the engine to immediately jump multiple teeth (5-7). The death was quick and silent, no loud metallic sounds or warnings. They have put a new belt on and corrected timing but the car doesn't start and seems like it doesn't have any compression.
How feasible is all of this? Wouldn't the AC Compressor belt, being brand new volvo part, slip before it snaps? Sounds like a terrible design by Volvo if a $15 belt can destroy an engine. The AC was also not on in the car and windows were down. It seems a bit suspect but I also now have a car that is worth $4K with $3500 in engine replacement and $1k in AC Compressor replacement.
Thoughts on needing a new engine or if you have experienced this, is the bottom end of the engine okay and really only needs a new head? Looking for opinions and possible direction as this is my daily commuter car and I just bought a house. Buying a new car doesn't sounds great so I am looking at a replacement engine or serious rebuild time?
Thanks in advance for any thoughts you might have or possible leads on an engine (I will continue my online search). I am also trying to get the shop to share some of the financial burden as they had their hands on the engine miles before it failed as the car was driving relatively well when I brought it in the first time...UGH!
