hi all
i went out to my 1988 90 td started the engine after about 20 secs pre heat
it ran but very rough even for a td then a bang lots of white and blue smoke from exhaust turned the engine off popped the bonnet and found a large amount of oil on the down pipe from the turbo.
my question is, is this a simple turbo has blown need a new one or engine has given up and needs a rebuild or tdi putting in thanks in advance for help.
