maybe it is bearings! theres so many names for different things
the way it was described to me, is that the subframe comes out and then the sump and then what i need to repair is there. sound like bearings?

you can see the bearing shells going into the connecting rod "big ends" near the start of the video. It is not uncommon for the crankshaft to be re-ground to ensure each journal is perfectly round and not scarred up. This part cannot be done thru the sump.

ah i understand which part now. shouldnt be too difficult me thinks. if it needs a new cam shaft then ill break the vehicle for spare parts. are you saying i cant replace the bearings through the sump?

no, it's the re-work on the crankshaft
which couldn't be done thru the sump.
