To save me some trouble.. does anyone know the socket size il need to undo the sump plug on a TH magna?

Thanks

24mm off the top of my head

I was just picking sockets randomly whilst lying under there... strangely the best fit on my 3rd gen's plug was 15/16" from the SAE set.

24mm, advisable to use a 6 sided socket so u cant round it off.

yeh but what is less than 0.2mm out so either one will fit the baby

yeh 0.2mm is enough to strip the sh1t out of it.. believe ME i no. i found out the hard way

24mm sounds about right. Had to do my oil change last weekend and I didn't have a 24mm socket, ended up getting the imperial sockets out, so 15/16 it is. But i better get the metric socket otherwise as Gremlin said, i'll end up stripping the bolt head off completely, then I'd be in trouble...

Mines a 24mm - used it on the weekend
Have fun doing your oil change :cool:

Thanks.. 24mm did the job.

I had to use a tommybar & hammer to take mine off 1st time, so I needed zero slop!


Mitsu dealer must have used a air ratchet, damned plug was screwed in real tight.
I didn't do it back up anywhere that tight and still there's nil leak.

15/16" AF is actually smaller than 24mm by 0.007" (7 thou), so it would be a marginally snugger fit than 24mm.
I would suggest your 15/16" AF would be a better spanner / socket to use even though the plug is actually 24mm. In other words, and assuming your spanner / socket is in good nick, you are not going to strip the plug with a smaller spanner. :happy:

Autobarn (so presumably everybody else) has replacement plugs with a flange and a deeper 16mm (from memory) head. I will be replacing mine on the next change, mine's a bit rounded from the mucking about I had to do the first time I changed the oil after a service a while back. Why the numpty mechanic thought 10,000Nm was a reasonable torque for a $#^&!* plug is beyond me.

A 380 sump plug fits just nice, it has a good deep head, and IIRC it's 14mm. You can usually get them from your local Mitsu stealership for just a few $.

Many years ago, I headed outback with our TM Magna, towing our caravan. We got as far as Mildura, and when we came back to the car from a short walk, my wife said that the car was leaking oil. "Nah, it must be some other car, ours doesn't leak oil". We got out to Wentworth, and again after a short walk, she said "our car IS leaking oil". "Nah, it must be the same car doing the same route as us". But I decided to check. The sump plug was fingertight! And we were heading up the centre... I always did my own oil changes and never overtightened the plug. After that, I tighten up a bit more, but never as tight as most grease monkeys do. I guess that if they strip a plug, they can weld a bar onto it and get it off easily and pout a new plug on - the customer pays anyway. If it falls off, they have to carry the burden, so they do it tight.

This all stemmed from a previous car, where the grese monkeys under warranty had checked the gearbox oil and tightened the filler plug so tight that I could not get it off. I finished up hammering a 16 mm ring spanner onto the 17 mm rounded off plug and got it off. I then dressed the hexagon and from then on it was 16 mm.

I've had to use an angle grinder on one of those 24 mm no-longer-hex-shaped sump plugs on a Sigma, to shave the head down to nothing before it would move. Ever since then I've used a torque wrench and replaced them ASAP with the smaller but deeper sump plug as on the 380. No problems since.

I had a similar thing as you erad, I drove 1700km straight and discovered after that the sump plug bolt was loose

I was very lucky

I replaced my sump plug with a new one from auto pro, came with a washer and cost $6. It's now a 14mm and very deep. Not a huge chance of stripping it now. Strangely the washer was white and plastic. Doesn't leak tho.

Check the plastic washer next oil change for cracks. I have a feeling they will do that if tightened too much.
Bought the same sump plugs + plastic washers, but bought aluminium washers to replace the plastic ones, at least I know they just flatten a bit when tightened. Just being cautious, really.

Wow, how tight have you guys been doing them? If the plastic washer is in good nick you don't need to tighten them up too much at all...

Use a torque wrench and take the guesswork out of it. 42 Nm says the manual, I do mine at 50 Nm, hence I prefer a metal washer to plastic.

Did an oil change on two of my cars yesterday, the Magna with the 380 sump plug and aluminium washer showed the washer conforms nicely to the hole in the sump, ie it squashes down nicely. Makes it single use though, so I ordered some more, eBay. 22 mm external diameter, 14 mm internal diameter, 50 cents each, ordered a bunch. Supercheap made me pay $1 each. lol

....or just use the "O" ring that mits use and sell, no need to put a plastic washer on a sump plug then????

Oh and I love the thread mine, great work

You mean that little "O" ring that always falls apart when you don't have any spares?

As for the 2005 thread mine - if it is of some (slight) interest to someone, why not? Lots of topics get recycled on this forum.
(Like your favourite, "What oil should I use in my Magna?") lol

Bugger, I didn't notice :redface:

I bought a pack of washers to use for my next few oil changes. They are the red ones you get off the rack at auto pro. I like them they squish nice and are cheap as. I only used the white plastic one that came with the sump plug as it came with the plug. Seems to work ok and didn't leak oil. I don't use a torque wrench but I grab the ratchet by the top top so you don't get much leverage at all and do it tight never had a problem doing it this way.

Just curious as to the tension between madmax and madmagna Is it because you both mad? Or it it just the usual fighting for alpha male spot on the forum.... Lol

Mmmm . . . Madmagna is the undisputed king of this forum. He has "hands-on" knowledge of the Magna and 380 no one else can match.

Sometimes I respond to a thread when I really have NFI what it is about, but Mal generally sorts me out and gets the thread back on track. It's all a learning experience in my opinion, no Alpha Male ego conflict at all. There used to be some of that in the past, but those people went off somewhere else. A different forum, I believe.

Interesting comments, usual comments so nothing new there

The "O" ring I have never seen one "fall apart" when it is replaced with each oil change.

If you are going to use any washer at least use an alloy one, plastic is just stupid as it will crush and split.

Um, why??

I spoke to Mal the other day when I called mitsfix and the man knows what he's talking about. He wasn't able to help me with parts but sent me in the right direction and gave me some good advice. I think I shall get some alloy washers for my next oil change. It is entertaining to watch you two go at it on the forum though hahaha :)

Yea well I wasn't really disputing the washer used, point is if you use one at all you're not really going to get a leak or whatever. It's a low pressure system so people tightening the sump plug to a point where they were rounding it off when trying to get it off next is just laughable.

any pod vs panel threads popping up these days?? they were my favourite

Ohh god....please, dont go there....lol

Pod filter hands down!!

Pod filter hands down!!

i disagree.. i got 1hp more from a panel

Yes, but a pod gives you more of that vacuum cleaner noise.

And we all know, more noise = more power = more cool = more street cred & more attractive to girls . . . . . right?

I hope I don't get an infraction if I admit it was a troll post.

I have a dyno printout showing low end torque drops but peak power is higher if I remove the intake snorkel.

Mitsu dealer must have used a air ratchet, damned plug was screwed in real tight..

When my factory warranty ran out on the old TH I tried to do the first oil change myself - after breaking 2 ring spanners on the sump plug and it starting to round off I took it back to the local Mitsi dealer and asked if Hercules could loosen it for me - service manager was very helpful "zipped" the car around to the service bay.... A good 1/2 an hour later he came back saying they couldn't get it out and asked what I'd used to put it in - I said I didn't YOUR service dept was the last to work on it. Anyway long story short - they called at 5Pm to say they had to drop the sump to get the plug out, so I had to go back next day to collect it. I then did the oil change easily.

And as my other car is a Jaguar XJ-S I ALWAYS use anti-seize on bolts and copper washers (You can reheat the washer to soften it and refit for a seal), never had a seized plug or leak after that (300,000Km odd and 30,000 in the next TJ)
