Right, I cracked the sump so jacked car up etc and whilst I was there jacked the engine up to add a spacer on the rear mount to give me more sump clearance. But then I noticed the exhaust was wedged against the tunnel. So took the spacers out and lowered the car back down filled with oil. Before I started it I took the intake tube off and gave it a clean and polished the filter tube up. Put I back together and started the car. Now it idles at 2-2.5k and jerks left right and centre. Now the bonnet was open when it started to rain but not a lot of rain actually got in anywhere. There's no smell
