doing an oil change on the Senator today, along with the oil cooler themostat. Took the sump plug off, old filter ect..... drained the oil. Went to put the sump plug back in, a bit of the thread just fell out of the sump  

Felt funny putting it in, started to tighten ok. But then it just spins  

Its on finger tight at the moment, and is a steady leak  

After a long run, and stopped. It dripps about 3 times a min, it then slows down. Done about 60 miles or so, its not gone down on the dip stick as far as i can see, but a sizable patch of oil on the road where it was parked.

Bloody typical, simple thing buggers up!  

Not got the time or tools to fix it (tap sets) halfords had opps all above M12, going to have to bite the bullet and take it anyway around Europe, but just keep topping it up and watch the pressure gauge.

The nut is still tight to the finger.

Mark, don't take it to europe like that, for goodness sake.

Let's have a look at it. How about a scrapper sump...

Scappers no good, no sennys around here.

Have to do something either tomorrow, or next Saturday morning.

No time during the week....

I think I will need an M16 to re-do the thread, and a replacement nut. But got no chance of getting on tomorrow...

:)I think you can get Threadlock or Beadlock from independant motor factors. You'd have to drain your new oil to get a clean thread. Might also be an idea to fit a fibre or rubber washer, not so much as a seal but if the thread's weak you do'nt want it vibrating out while you're driving.
      Might be a little tight undoing it when you get back but probably the lesser of two evils.
          Have a good trip and look after that Senny. [smiley=2vrolijk_08.gif]

Can you not get a Helicoil???  they go to the thread of the sump then the sump plug screws into that....shouldn't be much money either

Just a thought but would some PTFE tape around the original not help until you could do a more permanent repair?

:)I thought that at first but do'nt think it'd last long once oil got hot. [smiley=2vrolijk_08.gif]

Not familiar with the senny sumps but the omega ones usually strip the thread on the plug, not in the sump so you might just need another plug.

I'm guessing that it is sump, as bolt is steel, sump ali.  Tractor stripped the sump.

As for helicoils etc, going to that extreme, may as well just tap another.  Annoying thing is, I have a tap from when I did tractor, but its over at Mrs TheBoy's dads, and he's on hols

yeah bit of bugger that, put a old car matt under the car last night, just to top a stain appearing, might take it for a drive and then check the level on the dip, see how much it has dropped.

I kept my eye on the oil pressure gauge, stayed good under load at 5bar.

Does anyone around here local to me have Tap sets?

Tell me more about Helicoil, what is it what does it do if there is no thread on the sump.....

Retapping is probably easier tbh in this case...

What about searching the internet for scrap yards that have senny in might be of some help but if they do then it would be mail ordering the part you want. Worth a try.

It's no good trying to retap for the same size sump bolt. The hole in the sump will now be oversize and you'll just make it looser.
When you say the thread 'fell out', it makes me think that there was a steel insert pressed into the alloy sump and its this that has come adrift. More info please Mark.

The sump nut came off fine, but i think i over-tightened it previously. When putting the plug back in, feeling with my fingers i felt something loose, it was as shard of alloy which was part of the thread on the sump.

The nut was difficult to get going, but then went fine until it came to tighten with the socket. It goes up to finger tight ok...
