you just gotta take the sump off pal to get to the pick up pipe and then remove 2x 10mm or 13mm bolts and its off! and theres a little green o ring seal too, so when you get your new engine i really really can not stresss enough how much you should replace it lol it cost me what? a tenner for that and the seal, will not take long at all to do with the engine out. to check the turbo all i can think is feel the play in the shaft? see if its rough when turning about all you can do without striping it
