Drain Plug

A former Colleague used to have an Isuzu Trooper (big engine for towing) he reckoned the Owners Club was just about the bees knees for everything!

I assume are already aware of it If not I have put a link here:-

Hi Dave

Yes, for all the modern technology in cars these days they go and stick warning lights in them which are a complete waste of time.

There’s one thing about the old cars at least they had temperature and oil pressure gauges in them, I remember an old Humber Sceptre I owned, getting into that was like climbing into an aircraft cockpit gauges everywhere.

Yes it has to be said some of the modern technology is certainly a backwards step, unless of course manufactures don’t want car owners to know there is a fault until its too darn late.

Yes I'm a member of the Isuzu owners club and I did put a posting on there about plugs but did not have any replies, I guess it just depends on who reads the post, so I thought I'd give this site a try.

At the end of the day I've had the car for 14 years and the engine warning light hasn't come on yet to let me know it's time to replace the engine because lack of oil, so I guess when I put the plugs back in I must be getting something right

Hi Clive B1, did some digging and found the following link to parts lists for the 4jx1 engine as used in Australian market Trooper / Holden Jackaroo's.

However the oil pan plug gasket I found in the engine section has description 14 ID 20 OD (as on the ones I found for US gasoline / petrol engined Troopers, so Isuzu may have mixed and matched plugs and pans between various models sold around the world.

It also seems like the 3.0 TD engine was not sold to the US market at least not in Troopers, so I have not had any luck finding your specific model part list on North American sites.

Hope the info at the link helps, sorry I couldn't find more specific info.

Hello Jeff

Thank you for taking the time to see what information you could find, the oil pan drain plug sounds about right as it is smaller than the rear axle and gearbox plugs.

I will certainly download what you have found as it could come in very useful in the future as I don't think I will be getting rid of the Tropper any time soon and the exploded views can sometimes make things a lot easier when doing jobs on them.

As a matter of fact I had a look at the exploded clutch assembly which needs something doing to it because when I put my foot on the pedal there are more creaks coming from it than a haunted house .

So thank you once again for the link, you certainly manage to find things better than me.

Cheers

It's worrying how difficult people have found this simple car problem that your fathers wouldn't have though twice about.

Sealing washers should always be as thick as possible because it is easier to squash thick things than thin things as it is easier for the material to flow.
The undercut doesn't matter because you centre it by feel and eye as you do it up.
It's just a hole, roundish for neatness but not essential, but the outside can be any shape as it doesn't do anything.
You want an offcut of copper from someone who made a boiler or a bit of aluminium off whatever you salvaged from a skip last week.
After drilling the hole with care to avoid making it un-flat (use top and bottom waste material to drill though) anneal the copper almost red hot then clean with vinegar or for aluminium use the soap trick to avoid melting it and clean with scotchbright.
You should be able to reuse it for about 10 years. You won't ever lose oil suddenly just keep and eye out for it marking its territory. If it does make its mark make sure you know which section is dripping - engine, clutch (for crank oil seal) transfer or gearbox.

On the RR 200TDI I had a rather nifty drain valve. There was a hose you screwed onto it that opened the valve so the oil went straight into the can with no drips and even allowed for stopping part way to change can as it took 6litres.

Hi Bazyle

I do fully understand what you are saying, one can always improvise but as these aren't usually too expensive I'd pick the easy way out.

To start with if need 8 of them it's a bit of drag having to cut 20mm diameter holes in each one as I don't have a lathe and a 20mm drill is rather large which brings it to the point of having to drill a series of holes and then file it out.

I just thought it an idea to find out what others do as I'm sure they have come across the same problem.

Hi Jeff

You found a parts list for the Trooper, is there any chance you could find such a listing for a Vauxhall Omega B 2.5DT or Opel as you may know it, it's the one which has a BMW 6 cylinder lump in it as standard.

Cheers

Clive

This is your excuse for getting a lathe

is there any chance you could find such a listing for a Vauxhall Omega B 2.5DT or Opel as you may know it, it's the one which has a BMW 6 cylinder lump in it as standard.

Hi Clive, I would need the year and hopefully the engine model to have any hope of locating info on your car as noted. Vauxhall and Opel car brands are not very common here in North America but you never know what info there is out there. With more info on year and engine I'll have a look.

Hi Jeff

The year for the Vauxhall is 2000 the engine fitted as standard is a BMW 6 cylinder 2.5DT, I belive the same engine was also used in the Range Rover, P38

Cheers

Clive

Haynes manual for a Trooper, I don't know if it would be the right year.

**LINK**

The engine code for the BMW engine fitted to a MY2000 Omega is X25DT.

Unlikely to be major differences to the mechanical parts of the engine, just to the engine management system and other emission control equipment. The first letter of Vauxhall/Opel engine codes defines the emissions standard the engine meets.

Would these be any use?

Hi Clive, Re Vauxhall Omega 2.5 DT - I had a half hour look in all the usual places I look for car parts data - no parts lists or exploded diagrams. I did find a lot of parts adverts for your Omega and various bits for your engine from ebay and from UK based scrapyards. The mail order place I use had listings on Opel to 1975 only, Vauxhall to 1963 only, and no listing for X25DT BMW engine in the BMW car parts listings. Sorry, have no data for you.

Hello Jeff

Thanks for taking the time to have look its much appreciated, I agree the X25DT is a bit of a rare breed when it comes finding things for it, not so long ago I was trying to buy a new water temperature gauge sender unit ie. the bit which screws into the engine.

Absolutely no chance, fortunately it turned out to be the wiring in the end.

Thanks once again

Clive

Hi Martin

Thanks for the two links, as a matter of fact I've set for some of the crushable ones to see how they go.

I may stick a bit of sealer on them as well, belt and braces if you like, I don't care just as long as I don't have to keep getting underneath just to keep checking the oil level or finding a tell tail trail of oil on the drive.

Cheers

Clive

I you're worried about the washer centring on the plug, fit an appropriately sized O-ring in the undercut and that will centre the washer.

Good idea Mark, another thing that can be used is a bit of insulation from a bit of electrical cable/flex. A copper washer is not too hard to make, anneal it before use, and after it has been tightened a few times, anneal it again.

Can't see it mentioned that a motor factors has been tried, someone did mention it earlier. I've just done an oil change & service on our Rav4, all bits from the local motor factors including the drain plug which had a crushable copper washer and a thick fibre washer with it. Hooked blister type pack so obviously they have various sizes, Well worth checking, Having a quick look at a couple of Motor Factors (GSF etc) they do list the 2000 Trooper for bits.
