Hello from a newbie! Read with intrest post yesterday on cam cover oil leaks. My recently aquired 2.5v6 dumps oil outta them as fast as i fill it.However before i follow the excellent on site info perhaps someone could offer more advice. Both plastic covers on mine are badly warped-so bad last owner had siliconed both inside and outside around them to camoflage problem till too late!- and pointless refitting them. Im told this is common and best cure is to fit metal covers instead of plastic. Great news ..ive got some..off a vectra i believe. Bad news..not sure theyll fit. can anyone advise ? The oil filler is in a different place-on top of cover where mine is offset to passenger side-and looks like it will be covered by plenum And which gasket set do i need .? I note you all say use gen vaux.....help please if you know about this mod. cheers Richard in yorks.
