O ring replacement is easy and cheap

http://www.aulro.com/afvb/technical-...lug-fix-3.html

O-rings were pretty irrelevant for me as i had lost the entire cover. Got a new one now & fitted it with a metal strut over the front of it to ensure its held in place. Also fitted a new rocker cover gasket.:)

I may have another oil leak from the vacuum pump oil feed hose:(, but it could be I just didn't degrease this area. I'll know tomorrow after I drive it after degreasing this. It looks a bit hard to get at, but I'm sure I'll be able to sort it out.

Thanks everyone for your help:D:D Its nice to know I'm not alone, even if I'm having weird problems no-ones seen before:D

well after searching high and low scored a pack of 5 Viton orings from England through the amazon search, around $39 delivered to Nth QLD alteweb uk

BUT the cover is into the rocker space, and if you have enough pressure to force it out then you either have a blocked crankcase ventilator or so much crankcase pressure that the ventilator is overwhelmed. I would be checking the flat thingo in the inlet manifold .

Mine at 130Kk was so loose that it was a major oil leak but it still was in place.

I've just fitted a new O ring which I sourced from CAT (part #
2N-5243) which cost $6.99. The old O ring was very hard and brittle and broke whenI tried to remove it whereas the new one is soft and flexible.

The plug fits snuggly now and should provide a decent seal.

Being EPDM it will turn to cheese soon...

A correct item: BS330 Viton

Any good bearing company will have them.
