Or so I thought, spent half the day under the damm car thinking it was the gasket from the return pipe, replaced it and an o ring in the power steering line, well it still leaks doesnt seem to leak idling but leakes and drips down after a drive, I think it is the sump gasket as I originally thought, also brake looses power assist if brake is held on, let it go for a couple of secs and its all good, pedal goes rock hard, someone suggested perhaps a abs issue but no fault codes logged, is there any vacuum lines I need to check, I disconnected egr a while back, if it was a stuck caliper would that not just affect a wheel, $400 second hand booster nearly 900 new
