Civic Type-R Trouble :(

Just got back from Bangor with my mate and his Civic Type-R's engine management light came on the dash, wont let the car accelerate like normal (obviously the management restricting it), checked the dipstick and had oil all the way up the top and a LOUD knocking noise coming from the engine at mid-range revs, horrible problem, can anyone shed any light?
Thanks

For one its going to have so many sensors, id personally take it to Honda, or a specialist but then again i know nothing about cars!

thats gunna be costly aswell i should think. Honda's a very expensive in parts alone, sounds kinda serious.

Oil pressure light on too by any chance?

hmm is he dumb and over filled it lol. could be a blocked crank case breather if the oil is being forced up the dip stick.hmm tha knock aint a good sign tho

could be the o2 or the lamba sensours

does it sound like a diesel? mabye the rods are noking.... he should have gone vag....

any decent local garage can check why the eml is on, an most wont charge you or be £5 tops (dont take it to honda tho!!)

so many posibilities of wots causin it thers no point sugestin things really,

does ur mate live near you? bring it over to huw gers in pengroes nxt week an ill stick the scanner on it for free for him

Thanks for all the responses guys, turns out as he does rag the car the bottom end's gone so a new engine is in order!
Shame as the car is mental...but for all you VAG nuts he's swapping it for an Audi TT this month once the engine's in!
