UPDATE!!!
Well i managed to get the cover off ok, started to sand it down, but the rust was so bad i would need to sand blast it! so that idea went out the window
Now the real fun began putting it back on!
For starters i couldn't get the spacers in the write place, as i had to hold the baffle and spacers to the cover then flip it onto the engine block!
That didn't work, after 100's of attempts it got on my tits and started thinkinh, shit i can't get it back on!
So with my nerves, i thought i would try again, this time one of the spacers fell n the valves! :O
I shat my self thinking that was it im not getting that back out! luckily i managed to get it out without touching anything, fewww!
So finally got it all back on after an hour!
So i'm just going to buy a new cover lol
