THIS IS PROBABLY AND IMPOSSIBLE QUESTION!!
but i'll ask anyway. lol


Generally speaking, How bad do Cosworth Cylinder
bores wear, due to milage? (120k)
shes starting to use a bit of oil so im doin the lot
(personally im starting to think its more likely to be the turbo thats fooked lol)

as i wanna know if i should be expecting to buy .5 pistons
with my engine re-build bits.

I realise it would need to be done if the bores are scored.
but do bores wear that much?
