Hi , my 4.4 v8 L322 has recently had an oil change and since then when I start it in the mornings its very tappety for a second or so and once when I started it when it was warm the oil light took so long to go out that the dash warning said stop engine low pressure but was ok when restarted . The filter and oil are correct type and oil level is ok . any ideas ?

Could be a stuck tappet that frees up when warm. This can be caused by running with a low oil level. You can sort this with a decent engine flush usually but it will mean another oil change!

1. oil filter without a non return valve
2. replacement oil too thin
