TD5 oil drain plug thread

[fraser130]

Scott, they had no nippled ones in stock, so he's sending them next week when they come in. Hold on with the UK one, I have a mate who is an amazing machinist, if they need changed, I'm sure he can do it, and you could post me yours and I'll get him to do yours too.
I'll let you know as soon as mine arrives.

Thanks

If you are playing thread games PM me. I can supply taps and dies in virtually any metric thread you can think of and some you would not believe exist.

Thanks Brian, but I think the thread is fine, but we may need to turn down the shoulder on the taps to match the shoulder on the original plug.

Fraser130,

I don’t think turning the shoulder down is going to be the full solution.

While I didn’t measure the depth of the collar around the sump plug I’d estimate it’d be 5mm from the top of the collar to the bottom of the sump.

So even if you turn the shoulder of the valve down, the leaver housing (on/off) I think will foul the collar when you attempt to screw it down.

So you would either need to pack the valve up say 3mmm allowing 2mm for the standard washer. Or grind the colour completely down or a couple mm off so it doesn’t foul the on/off leaver housing after reducing the shoulder of the valve.

As I haven’t removed the sump plug I’ll be interested in the possible solution.

All good fun

Ahhhh, I see what you mean, Mine haven't arrived yet, but I want to change my oil as soon as it does, so I'll check it out as soon as it arrives, I guess it all comes down to the thread length in the sump, it woul db nice to have the valves' thread level with the inside of the sump (if it's long enough) and use a spacer to drop it down so the valve lever works.
maybe?
I can take my car off the road for a little while to sort it, if I need a spacer, I'll get my mate to make 3.

I guess we'll see.....

Well Scott I'm not impressed!
Not only is the shoulder in the way, but the thread is WAY off!
I've emailed him to see what he can do, Has your plug (on the car) got anything written on it?
Mine says "UNC 4.8"
The thread on the new valve is significantly smaller, I'm guessing here that his sizes are for the V8 maybe???

Edit:
Jack at fumoto has been very nice, he's sending me another valve and an adaptor and a postage paid envelope to return the other 2 I bought.
I'll take photos of it installed once it's done so others can see how they fit/protrude.

So did anyone get anywhere with fumoto drain valves?

I'm thinking of getting one because it looks like i've just pulled all the thread out of a previously bodged sump... the hole that's left behind is 15.7mm
Pitch on the plug is 1.5

So i'm looking to re-tap the sump and fit a larger size plug, but was going to get one of these valves so I never have a problem with a bloody aluminium sump again!!!!

[scott oz]

I've ground the skirt down on mine but as yet have not attempted to fit it. So I don't know that it will clear the skirt on the sump without the skirt being reduced in height.

The fact that the supplier sent an "extension" which effectively dropped the drain plug down abut 3" which to me makes it unusable for offroad says it all. Also from memory the flats on the extension wouldn't clear the sumps skirt in any event.

Given the above and Fraser130 comments I'd go for the English one as you know it would fit.

[reeksyofoz]

Cheers for that Scott, but the damage means I'm going to be drilling and tapping ... and definitely with a larger pitch so it doesn't happen again

That shoulder on the sump is a pain in the backside though so I'll be looking for an allen head bolt to suit.
