Hi everyone ok 323 v6 100,000 miles smoking badly ish and only sometimes when pulling away after sitting in traffic for a few mins also very badly when you hit that magic 5000 rpm mark, I have done 2 engine flushes and now using 10/40 oil there is also i bit of a rattle from the bottom end when you rev hi then lift your foot of the gas... so how much for a new engine or a refit????

Thanks nick

New engine ? Mazda £4,000 upwards - but that might be for a fully rebuilt one

Scrap yard - anywhere from £200 upwards depending on mileage

Fitting depends on hourly rate but you are looking at about 10 hours

hope that helps
