Thanks tiger, i think i'll get new side covers
Dan, what does NLA mean?
NLA - No Longer Available.
Try a new seal first. if it still leaks get the bushes and have them machined to fit by a local machine shop.
I once knew of car which needed a bush done very quickly. The guy fitted a new bush and 'reamed' it with a flap wheel. I told him it was a very amateur way to do it, but he was desperate. The car ran without any oil leaks - he fitted a new seal - and was still doing so over 2 years later.
I'm not advocating doing this, but if someone is desperate it can be a 'quick fix'. Not advised, but in an emergency it can work.
