im going to be cheeky here and ask some advice for my mothers car!!
although its not an astra, its still a vauxhall!!
its a 1999 corsa 1.2, pretty sure its the ecotec x12xe
about a year ago the egr valve was playing up, so had it cleaned by a mechanic who is my uncle for free and it was fine.
now its misfiring slightly on idle and under 2krpm, with oil in the cylinder number one, i changed the spark plugs and there was oil caked on the first spark plug.
just wondering if anyone thinks its the egr valve cocking up or if its a worn piston ring letting oil squeeze past the piston and sitting on top of it.
anyone know how much it would cost for either to be sorted out? any info will be greatly recieved
