Hi all I've had a strong smell come from the petrol filler area for some weeks. Today I got it on the ramps and thought I'd check the tank and hoses attaching from the tank connections were ok... after a few seized bolts all looked well.

We then looked at the simple route and the petrol cap oring has cracks our 4mm long all round it... could this be my problem? I tried putting some geese on it but didn't make any difference. Also I have notice a little lumpy running at idle that may be coincidence but seemed to happen around the same time...

I'd have thought adding geese would make it even more quacked.....

errrr ... I'll get my coat.

Seriously - not ever experienced anything similar ?!?

Hmm ok meant grease lol - well I swapped with my m6 one and it fits
It's the same but that too is cracked nearly as bad so made no difference think I will order two rings for now
