the car i have has a blown bottom end really badly and is smokin really bad...but is this caused by the bottom end or could it be possible turbo failer.....iv checked the turbo a tiny bit of play each way..but thee was a bit of oil in the bottom boost pipe...but i allways had oil in the top boost pipe on my 5turbo nd that never smoked.....so will a blown bottomend cause heavy smoking lol .................iv never blown one....when i say blown botton end i mean nockin badly...what u lot think

 

If the bottom end is knocking i would think somethings not right in there.

 

yer its fucked lol
