First time servicing my Disco

[balvenie]

My Disco is a May '97 V8 and it needs an oil and filter change. It will be a crawl-under job and on the weekend I managed to locate a huge sump oil catcher which should help to keep the garage floor clean. But I need help with the sump plug gasket and an oil filter, especially the filter. Presumably after market is cheapest and I have looked at the R%@o site and studied the numbers in the book at the el cheapo auto shop but they don't seem to match. I could have screwed that up though. In addition, I need to know the ID of sump plug gaskets and the metal they are made of too.
My old car has been with me since new and has had a small variety of mechanics. The last one installed a red oil filter. That's all I can tell you. There is no brand that I can see. If this can be carried out successfully there are all sorts of things that need doing but this will keep it going for 6 months at least. In the past all I have worked on is my motorcycle but it is hibernating while I have been recuperating. At any rate, I am reasonably proficient with tools.

Thank you in advance

Don't worry about the copper washer under the sump plug, mine has been re used for the last 5 years and still does not leak, its just another con from mechanics that it needs replacing every change.
As far as filters go just go to repco or the like and ask for a D1 V8 ryco filter, some crap mechanics use a Z9 on the rovers but the oil pressure will drop slightly so use the correct filter. Z89A from memory, should be about 17.00

I generally just buy a service kit from Roverlord here. You know you're getting proven quality parts, they arrive within a couple of days, and include the new copper washer. Also includes a fuel filter and air filter, and, if you want, a filter and gasket for the auto. Plus they are long-time supporters of this forum.

I, too, have re-used plug washers, but if they're available, I'll use a new one.

When you use a new copper washer, your sump plug will be the only oil free part of the engine. 😂

You should not use Z9 as they are longer in length and supposedly at full articulations they can get ripped off

Not with the v8. Z89a is a better fit tho.
Last few rycos that I used, I had problems with the drain back valves.....

Last few rycos that I used, I had problems with the drain back valves.....First ryco I used on the v8 I done it up hand tight like I do on all my cars. Started er up and it was pouring out the seal and fast too. I had to do it up with the wrench another 2 full turns I was pretty surprised. No big deal it's not overtight, but it's not leaking now so all's good.
Cheers Jim

Did it have a gasket? Forget it and filters can leak.

Without a gasket, tightening would not stop the leak. More likely would be the old gasket remaining stuck to the mount and you ending up with two. Even more likely is that the thread was a little tight for some reason. I use Ryco for most servicing mainly because they are easier to get through Bursons and they do need to be tightened 2/3 of a turn after contact as advised.

Urban Myth??

Please by all means correct me if ANY OF YOU have had one "ripped off"

Yep been guilty of exactly that in the past.

Maybe on a 300tdi, can touch diff i think. No problems on either my 200tdi or v8.

Wow; never realised I could get so many replies[bigsmile1] Thank you everyone and I have a Z89A:thumbsup:. I think tomorrow will be the day.

will cost you a bottle of balvenie.

So; You know single malt scotch eh mate. I belong to another forum where they know everything from SM Scotch to rotary engine aeroplanes, so it shouldn't surprise if this forum is full of knowledgeable people too[bigsmile] A bloke we know is a great SM Scotch man and I think I have converted him to Balvenie but every time we meet, he trots out something different (he is a really good bloke). One time he had some really smokey stuff. Laphroag??
A whole bottle might be a bit rich come to think of it Fausto. How about I drink to your health instead[bigsmile1]

As promised, today was the day but there was a hitch. El Cheapo got its advice wrong and the sump plug gaskets do not fit. For reference and FWIW, my car takes a 21mm internal diameter washer. Did a ring around locally to no avail and emailed Roverlord. To my surprise he rang me, all the way from Victoria! As luck would have it, I was out and he mailed me later with a part number. Tried to order but could not figure out how to do it either on his website or his ebay shop. Curses foiled again as Oilcan Harry would say.
BUT my wife recalled a mob that I had forgotten and sure enough, they had some so it's on for tomorrow [bigsmile1]
Another bit of good luck 1) Having the huge sheet of plastic under the car makes sliding around quite easy[thumbsupbig]
2) The oil does not spew all over the exhaust pipes and goes straight into the the whopping great catcher I bought[bigsmile]

[Rick1970]

If the oil didn’t hit the exhaust, guessing you did it cold. From memory the sump plug is 1/2” BSPP, quite odd in the automotive world, usually unf or metric.

[balvenie]

I did do it cold Rick. Can't hide anything from you blokes can I[bigsmile]
Do you use something to keep the hot oil off the pipes, like a sheet of tin? It looks very awkward to get something in there and thanks for the heads up. Would never have expected there to be a difference between hot and cold oil:redface:
Picked up my sump plug gaskets this a m. Another surprise: they are the "wind-on" type. Never heard of such a thing.

I was expecting metric but the hexagon is 1.130 inches or 28.702mm according to Google. I gave up and used a shifter.

[Rick1970]

I do it hot, burn hand, then clean up and mess....
Mite modify a plug to drain it a bit slower one day.....

[balvenie]

Thanks Rick[bigsmile]

A piece of tin about 150mm wide and 200mm long, bent into a shallow vee and wedged between the sump and the pipe directs hot oil into the catch bucket quite successfully. Mind you, an oil evacuator via the dip stick tube is even easier, makes you look like a pro too. [thumbsupbig]

[balvenie]

Thank you bee utey
Might have to look up the price of an evacuator[bighmmm][bigsmile]

Posted this info in another forum .. but if you want the easiest solution get a quick connect sump plug for it.
Cost a bit of $'s(possibly over $100 or so) but then it's totally tool less, never any worry of dropping sump plug into oil, and properly mess free, as you ten drain the oil directly into the container you dump the oil out with.
ie. you don't have to dump oil into a pan which then needs to be transferred into another container to take it to the recycle place.

I got the Femco click drain system.
So the procedure is:
Oil is always fully at temp. Undo the brass cap by hand. Connect the click drain to the bung still sitting in the sump plug. Click connect has a bit of hose on it's end, oil drains directly into an old oil container.
I let it sit for as long as possible whilst other stuff gets done at the same time, mainly to allow the oil to fully drain out of the clear plastic tube, but there is always one drop that want to escape. even the smallest rag deals with that.

So draining the sump is a completely clean affair now. Just need to work on a system for the 300Tdi's oil filter too now.

ps. if the sump plug is 1/2 BSP wouldn't that be the same size as the radiator and coolant bleeder bungs?
Can't remember sizes and stuff, but I thought 7/8ths(??) or 21mm was the spanner sizes for those two bungs.

[rick130]

Maybe on a 300tdi, can touch diff i think. No problems on either my 200tdi or v8.Yep, the diff will bash the bottom of it with a 300Tdi, but some judicious use of a 5" grinder on the diff casting alleviates the issue. [emoji56]

[balvenie]

I will have a look for that too, AK83[bigsmile]
The deed is now done. No leaks after a 5 minute drive to the shops but I will check in the morning.
BTW It took 17 seconds for the oil light to go out[bighmmm][bighmmm]:unsure::exclam: Only a couple of seconds when started the second time.

I try to never fit a completely empty filter. The more oil you trickle into it before fitting the less time you have to wait for oil pressure. Also, drain and refill the sump before you remove and replace the filter. Then start the engine reasonably soon after that. Letting the oil pump drain dry is unwise.

[discomatt69]

I always fill the filter, makes a bit of mess when screwing it on but I would rather that than no oil pressure

[balvenie]

I would never have dreamed that the filter could be removed from a full sump. There have been lot of surprises for me in this little journey[biggrin] and I appreciate the help you all are giving me :thumbsup:
