Hi,
I just done a simple oil change and now I have really stuffed things up.
I was reading online that over filling the oil actually damages the engine.

As I don't have a GQ Patrol manual readily available, could someone please tell me how much engine oil is needed? (6 cylinder, 4.2 Litre Diesel) from a GQ 1990 Patrol.

I really cant believe how a simple oil change, after all the other things I modified on my vehicle, is the one to get it undone.

I put in 9 litres of oil yesterday. and today I went to drain the engine oil, and nothing comes out! I mean it was not leaking oil from the 20km I driven. and it wasn't burning it up because there was no black smoke from exhaust.
I needed to drain engine oil out due to a whining sound that came from the 1,2,3 and 5th gear when driving. Furthermore, at about 1100 RPM the engine shakes just noticeably.
I feared that the problem was over dosed in the oil, but now there is none to be coming out of the bottom bung.

Thanks for any help...
