Juddery A160
 

Hello, thanks for taking the time to read this. Bought an old A160 a few months ago as a reliable run around, great little car but drove it about 10 miles across the local common about 10 miles at around 60 (normally suburban traffic) everything was fine, next day however it started juddering its 2000 miles past service, and checked the oil, was o.k on dipstick but the filler cap had a viscous yellow residue in it.

Any thoughts would be gratefully received. Thanks

Thank you very much
