HI!
no i don't have VVT on those cars...
and i don't think volvo ever used VVT on T5...
i'm sure the 2 covers are on the good engine
ne is mint and the other is oily.......
on the volvo procedure, thy use a tool made of 2 long screws, set in the spark plug hole, to compress the cover on the head.
I'll try this afternoon to bolt the cover very slowly, turning the bolt by hand... and we'll see...
but it's very strange...
thanks to you
