i think its finally dead
 

I posted this on FB , but I thought id post her for help too

"Well , I think ive finally killed the 4.4 :(
parked up after work , having a laugh with my mate and his quiet revving car, he took his to 3k and I took mine to 3k , mine sounded nicer with the x pipe on it , when it settled down , I got a red oil symbol with STOP!lowoilpressure came up on the dash ,now the car was parked with the front right higher than the rest of the car,
but I went off when you accelerated, so I thought it was low oil. with it being parked on a slant for 20 minutes
checked dipstick , when I got home , 3miles ,and put 1litre of ll04 in and fired it up , oil lights on again , and I'm not 100% sure but I'm thinking I got a noise coming from the engine now :(
but seeing as its 04.40 im not messing now
update, I had to take car to parents and get backup car, x5 ran ok ,on motorway (freeway) :) no lights no other noises, came to end of mway, red light on again , pulled up outside parents yup got another noise from engine, for definite, not a knock or a bang , and turned it off as I needed keys, check oil level,
what's the amount of oil to take from low to full? . 1litre ?.
ill take a video of the noise when I go back later,
I have done plenty for this car , and I went past the point of no return ages ago ,I just don't want it to die due to the one thing ive actually looked after, that's the engine ,
to sum it up , steves pretty upset
