Oil Filters

[Smally 01]

I have a 2006 Patrol Ute with 4.2 6 cylinder turbo intercooled diesel. I've been advised that there are two different oil filters ( Z503 & Z 416). Does anyone know what the difference is and how are they fitted. Which one goes to the front.

It's pretty obvious as the threads are different. Your model however should have the engine with 2 of the same filters. Only the early td42t engines had the different ones then they went back to 2 the same

Mine is the same as yours but a 2005, the filters are both the same.
It is a shit changing them as oil goes everywhere. Started leaving it to drain overnight and the oil left in the filters is way less.
Also move the fuel filter out of the way to give better access.

Mine is an '06 4.2 TDi - 2 x Z503

I have to admit my amazement that after a century of developing the internal combustion engine for automotive purposes & the '06 TDi being the end of the line of that engine's evolution that such poor consideration has been given to the ease of basic servicing. Whoever made the decision to make those filters so inaccessible should have been shot! And for any new owner .... it's impossible to see which filters you need until you remove the old ones which is a pia unless you live next door to the filter shop.

I like the idea of letting the motor drain overnight to reduce the amount of oil in the filters.

Using filters that have an anti drain back in them also helps, it's good for start up as well as the filters stay full and oil pressure is gained quicker.

Do Ryco's have that?

I can find out

It seems they do cuppa. You will generally notice when they are new the oil light takes about 2 sec, as they go through their life (hot,cold, pressure etc) they will lose a bit of tension on the anti drain back valve and may take up to 5 sec. This can many variables (filter quality, oil quality etc)

So with Ryco Z503's letting my motor drain overnight won't do much to reduce the quantity of oil in the filters prior to their removal then?

It will a little. I havent seen a filter thats perfect at it, plus there will always be residue in the filter head.
