Major oil leak at rear

Hi im new to this and seems a helpful site...i brought a wagon sport but fitted with turbo lump ecu etc...

had the car for about 3 weeks now but picked up a really bad oil leak last week...where the box meets block is covered in oil underneath,,i know this is the lowest point on car (well bracket under it)

But changed the rear crank oil seal today and the bell house was covered in oil and so was the starter motor(inside box)...but im still leaking oil now and dunno why??

Within about 2-3min of parking up after a drive there is a area of oil roughly the size of the palm of your hand

Turbo side of the engine seems to dry higher up and cant see any leaks above with the intercooler off

Is it just a cam seal or rocker gasket...

Re: Major oil leak at rear

rocker cover tends to drip ontoi the downpipe when it goes, is there any evidence of that?

if you can i'd clean the whole of it and then fire it up to see if you can see the leak.

This cover is oil separator cover and it's possible that it leaks here. Remove cover and inspect it - if it's cracked get a replacement. When replacing use sealant...

Yeah i changed the oil seoperator plate as it was leaking due to a little hole near one of the screw holes and replaced it with new metal one

also changed the o ring on the blankin plate the otherside as was slightly leaking to..fitted new clutch aswell while out..and all seems good just slave has decided to start leaking now
