Keep an eye on your oil level, not just in the short term either
Did you find out what went wrong with the old turbo?
From what my brother told me when he took it to the turbo specialists, they said that a small rock/stone got to it and wrecked the bearing/internals to it. Not sure how much of that is true but the insides were pretty much wrecked.
Just waiting on my oil feed pipe now and will get it all back together. Could the oil pump be messed up too which maybe did not feed the oil to the rest of the car?
get garage to check oil pressure
If the turbo has ingested something then you want to making sure it doesn't happen again. Changing the oil and oil filter is essential and you also want to be replacing the air filter and checking that everything is ok in that dept. Doesn't take much to wreck a turbo compressor wheel when something hits it due to the high speeds they're spinning at.
Oil gets low, bearings get hot, seals fail, turbo's knackered, that's my guess lol
Seriously though, what else could kill a turbo other than a lack of lubrication?
