went out tonight for a spin, checked my oil to see it was below the minimum mark so i topped it up with around 3 quarter litres, checked it on the dipstick and was about half way, after about 20mins i stopped in neutral, engine revs dropped to around 400-600rpm smoke coming from the bonnet, popped it up to find oil gushing out the rocker breather EVERYWHERE, engine sounded fine, it drove fine, tested the boost to see if it lost power and it didnt, my dad reckons ive done all the seals in my engine, so fucking stressed right now, what can it be?!
