An update on my situation chaps, i have taken the sump off and all the shells to discover that yes they are gone. The crank looks fine, no swarf or uneveness just looks spot on. I have decided that i will change all the shells and then make do with that till i have saved the money for my new engine. Oh yeah i will change the cam as it would most likely be fucked after being starved of oil. What do you lot reckon????? its either that or the car be off road for 8 months till i got the money for the engine i want.
