Thread: My 1st oil & filters change

Thanks Mike. Somewhere here on the forum (I think) I saw someone talk about relocating the filter to a chasis rail ... and changing the filter to the std old Z9 ... apparently much bigger, much cheaper ... might be worth the effort.

Mr Urban Panzer ... I'll keep an eye on it. I guess a _little_ nip up is probably a good thing ... and thanks for your Disco2.uk web site ... that just makes all the disco specifics sooooo easy for us first timers. You're a bloody ledgend mate

Hi Graeme ... where does it say that in RAVE ?? ... there's alot of stuff in RAVE and I haven't covered a 1/4 of it yet.

The oil pressure light stayed on for 1 to 2 sec's longer than a standard start ... a 5w oil travels pretty quick at 58psi. Please correct me if I'm wrong, but when you do an oil change, you drain the sump, and as the level of oil in the pan drops there's a vacum developed above the falling oil level ... small, but none-the-less a vacum ... which may draw oils backwards under vacum out of the oil galleries ... IF air can get in to break the vacum ... If changing the filter first will allow air into the system to assist the drain of the oil galleries, then maybe I can understand, but I tend to think it's not an issue ... ?? Is there a non-return valve in the oil pump ??

Edited to add ... according to RAVE, there's a non-return valve on the oil gallery entry to the head ... page 12-1-34 or there abouts.

Feral ... yep No need to pay someone if you can do it (properly) yourself. I'll check the Transmax out. Thanks.

BMKal ... Excellent idea ! I will knock one up at work. That will work easy as it will work around either side of the turbo oil drain line from underneath. Sweet !

Gary ... Looks like a more sensible tool for this job than my "ring" type tool. Thanks. We could use these at work as well (small engine repair & servicing).

Pedro ... You Betcha ! I'd checked the complete Disco2.uk web site over long before I bought my Disco ... It's an excellent reference site !

... and, Loving It !

So, I changed the ATF on the weekend. Pretty straight forward. Dropped exactly 4L of old ATF ... still reddish with a brown tinge ... no lumpies or foreign bits on the drain pan and no burnt smell. Good!! Topped up with 4L Valvoline ATF DX-3 and went for a drive ... shifts a little smoother (not that it wasn't smooth before), but the torque converter now locks up sooner than it was before ... hopefully another change will get it locking up closer to the stated 72km/hr instead of the 95 it was doing ... and now currently about 80-82km/Hr ... once locked, it doesn't unlock until 72km/hr (1750rpm) ... old or new fluid. I can see why locking up below this 1750rpm might be an issue with labouring the engine ... ?? If I drive like a grey nomad the TC lockup seems to take forever with more road speed required ... If I drive with a bit of gusto, she locks up pretty quickly not long after 80km/hr.

4L out of 9.7L means I've only changed around 40% of the ATF .... I'll do a weeks running then probably drop the pan, change the filter, and add another 4L of fresh ATF ... which will leave around 3.35L of the old original fluid ... then a 3rd change will leave around 1.4L or 15% of the old fluid ... and that will do until the next 10k oil & filters change where I'll change the ATF to Transmax Z ... if the budget will allow

Coolant flush/change (Nulon OAT), diffs, transfer case, power steering, brake fluids to go ...

I have never had a filter spin off and I just use my hands...no tools required.

With the money save by not going to the workshops you can now replace all the oils & filters with the best.

With the auto....try Transmax Z. Its very good. Change your filter too. Just remember this still holds heaps of fluid even though you have drained the pan. The auto smoothness is measurable.

Keep at it...the're a joy to work on

Where did you buy Transmax Z? I couldnt find in Supercheapauto.
and what do you use for Transfer, front & rear axle?
I am planning to do my first oil change as well. Thanks

anybody that sells castrol oils,,,
