Hi peeps my 2001 petrol pug 110000 miler is due for another service in may 08 It had a full service in may of last year. I was thinking of changing the oil and filter myself .is this an awkward job on the d9 petrol? I gotta trolly jack but not ramps or axle stands got spanners do i need sump plug washer etc ?any advice would be appreciated from owners who done this job before. In other words talk me thru it.

Quite a straight forward job, I just did mine. Get yourself some axel stands if your gonna do it, you need to get under the car and a jack is very dodgy. In the haynes manual it goes through each step even if it does tell you the drain plug is in the wrong place.

[Donnie Darko]What's the point of a trolley jack, if you ain't got an axle stand?[/Donnie Darko]*

You don't need to get it that far in the air to get to the drain plug but obviously, it makes things a whole lot easier if it is off the ground. Go on, buy some axle stands, you know you want to


*actually, it's "what's the point of living, if you ain't got a dick?"

I had no problems getting under mine without a jack/axle stands.

I drove the front wheels onto a few bricks i had laying about

change the sump plug washer everytime as well

*wonders if he should mention he's never changed a sump plug washer*

Found one yesterday. While pouring the used diff oil from my jeep out of the oil catcher tray into an old bottle something got caught in the funnel, lo and behold a used pug sump plug washer

Speaking of which I knew the rear diff in the jeep was passed it's best, but the drain plug is one of those magnetic ones that attracts any metal filings in the oil, the dome of metal & oil scum on the plug was about 2cm deep. Good job I was draining it to swap the diff really, enabled me to give the inside of the housing a damn good glean before putting the new one in

Me too

The biggest problem by a mile is the undertray. If you try to remove it the fixings *will* break, then you will spend the next hour fabricating washers and tie wraps (if your lucky to have such stuff lying around) to make it fit again. All this whilst restling with it on your back with 'bits' falling into your mouth, eyes, hair etc.

Then comes the filter removal! the purflux filters have a lovely big squishy rubber gasket when you first fit them and you fit it with a nice film of oil, not too tight! just another quarter turn etc......Then over the next few months it welds itself to the filter plate You should be able to undo it with a filter wrench (get a good quality chain type wth a socket attachment) once undone this then proceeds to piss oil all over the a/c compressor!

A simper way:

Leave the undertray in place let the oil dribble over the back of the tray but use a big catcher incase it produces multi-drips put *plenty* of sheeting down. Stuff *loads* of blue paper or old towelling over the a/c compressor and under the filter area to catch the initial pour from the filter.

You will need loads of rags for wiping the undertray etc and poly bags for disposal.

You can re-use the washer. If you're clever you can 'aneal' it my heating to cherry red then dunking in cold water to make it soft again but just buy one with the filter and get a purflux filter from the dealers for what they cost.

Oil wise, any reasonble make 10W/40 semi synthetic will be fine.

Sometimes, it's worth paying someone to do it just to save on the mess/agro

The undertray's a pain the first time. When you've wrestled it off, chuck the rear screws away (the front ones make it easier to locate properly if they're fairly intact), drill some holes in it and use zip ties to put it back after.

Seriously it's MUCH easier to cut and replace zip ties than it is to keep fighting with rusted screws.

I don't have any problem at all with the undertray on mine. The screw type things turn 90deg then drop out. Then when you put them back in they just press straight in and turn 90deg to catch, if they aren't home all the way you can evern press them in a bit further without having to turn them at all.

Oddly on mine the screws were fine, you could always buy a new set, I have changed the oil a few times and the filter could be undone by hand I suppose it depends on who fitted the last one. I don't know how much a garage would charge but my guess would be more than it will cost you to buy some tools to do it yourself, then you have the tools for next time.

The screws are only half the problem. The other half is what's rusted at the other end of the screw.

Then again, I'm talking about an 11 year old car here

Neither of mine have an undertray. Are you sure they're actually necessary? (Apart from catching dropped tools of course). Couldn't you take it off and, you know, leave it off?

Given the amount of deep scratches and dents on mine, I'd say 'definitely'.

Also I suspect it's a big aerodynamic aid at high speed
