2001 V70 T5 Crankshaft is gone.

[Cerutti]

Hello folks. Have a bit of a big problem here...

I brought my car to garage to fix a cracked radiator and a broken turbo. There was also oil leakage on camshaft seals, which let the timing belt covered in oil. Asked the guy to check the PCV an dit was clean. I also complained that at 2.500 rpm I could feel an extra vibration on the cabin, well, changed both engine mounts. Timing belt was changed with pulley, tensioner and so, all Volvo parts. By the way, the timing belt in place was around 60.000 km.

When I got the car back, the vibration was almost extreme. The guys said it would be related to the new mounting parts. Well, 40 km later, I got the message that lubrificant fluid was low. I drove around 30 meters and parked the car. Electrical messages showed up, including transmission to be serviced, low battery and authorizer. The car didn't start again, engine was completely dead. Well, I ordered an volvo DICE / VIDA and it arrived 4 months later; Few days before it arrive, the guys from garage called me and said the crankshaft was gone and the cause would be related to a failure on the oil pump.

Car left the garage with 5.2 liters of 100% synthetic oil and full of water and coolant.

Do you guys have any idea what could have happened?

Fixed turbo (original specs) sending too much pressure on an engine that was 182.000 km?
Turbo oil hoses connected on a wrong way?
Timing belt tensioner not properly installed?
Crankshaft left out of position?
Objects went on the engine via the intake when removing it for PCV check?


Thanks in advance folks

It is difficult to speculate on major engine failures like this. An oil pump failure on a Volvo is rare! it is more likely oil and coolant mixed somewhere and proper lubrication was lost

The first garage doesn't seem to be that skilled. Try go to some other place. I doubt the crankshaft is in cause, it sounds more like the mechanic is looking for random repairs. He could have made a mistake when replacing the timing belt.

When the mechanic replaced the cracked radiator it could have affected the coolant hose going to the transmission. Make sure there is no transmission fluid leak inside the radiator (a common issue).

Also, the PCV system was probably clogged somewhere in the past, because of all the oil leaks through the seals - leaking oil seals means the PCV was solid clogged for a long time. Did you bought the car recently? When the PCV box gets clogged, the oil passage inside the oil pan gets clogged too. When the box and hoses around are replaced, the oil pan should also be removed to clear the oil passages inside, otherwise the PCV system will still be stuck.
