v50d 2005 vacuum and turbo probs
Hello to all. New on this forum but not to the marque having owned several Volvo's over the last four decades. 240's. 740 estates. 740 Turbo. 760. without any major problems despite the "Starship" mileage of some. However the current 2005 V50D Sport with 224k miles is letting the side down a little. The turbocharger has started to eject oil from what appears to be the exhaust coupling and causing the resultant blue smoke coming up from the back of the engine compartment. This occurred from start up after an oil and filter change. I doubt it is the original but if so it has been amazing. Just how difficult is the turbo to change out on this model? It looks like removal from underneath? Any advice greatly accepted.
On another issue does anybody know what pressure the vacuum pump should pull in inHg? Thanks all. |

Turbo feigning death
Well looks like turbo trying to fool us. All symptoms of oil seal gone. Huge clouds of blue smoke from exhaust and from manifold area. Turns out to be differential pipe from DPF broken off and blowing exhaust smoke up from manifold area and also causing DPF differential sensor thinking filter is blocked and putting engine in a permanent regeneration mode and pouring excess diesel in, thus all the smoke. Anyone need a good used Turbo? Another lesson in assumption is the mother of all mistakes.

Turbocharger replaced. DIY.
Well me and my big mouth! Even though what I said in earlier posts were correct I have still ended up changing the turbo and it was knackered. Not the easiest job in the world but more awkward than technically difficult. For those interested, pulled bolt from rear gearbox mount, removed two bolts from top l/h engine mount ( looking at engine ). With exhaust disconnected from turbo you can pull engine forward an inch or two but it is enough. Remove egr and cooler for access to manifold bolts. I also removed egr cooler water pipe that bolts to rear of engine ( looks like an old fashioned thermostat housing ) to give more clearance to remove turbo. Drivers side driveshaft to remove also. Turbo then can be wriggled out downwards after disconnecting oil pipes, bolts etc. Job carried out in my normal size garage with car on stands.
