Right my mate is a proper petrol head, has lots of cars and knows his stuff he is just telling me stuff to get lol. I will just be the one handing him spanners to do the job, my special tallant lay elsewhere in a different job. What other gaskets are there below the head apart from the sump I know that 1 and I am not a complete mong when it comes to cars i just do the oil change and small things but would rather someone who I trust do the hard parts as I would make a hash of it. Can you help out with any sites that sell conversion kits you must know what that is if ya into doing stuff on cars yourself???? I have never heard of it that is the whole point of asking the people on a BMW owners site is it not?
