td5 leak

[pigeonbasher1]

just discovered an oil leak from the sump plug, it turns out the threads have been stripped, a friend recons its been tightend with a impact wrench, so we've dropped the oil and wrapped ptf tape round the plug for now, but is there a more permanent solution please, atb ray

Might be too thin for a helicoil, second hand sump probably best best

Either a replacement sump, or you can buy a sump repair kit that includes the necessary drill bits, thread tools, inserts and plugs. It's not unusual for a new hole to be drilled and tapped in the sump near the original. You would need to make sure the metal was thick enough to accept at 3 threads of the new bolt at the very minimum.

 

I would personally try to rethread/chase the threads of the existing hole. If this couldn't be done, I would drill and tap the hole for the next available size.

For the sake of £50 I would just change the sump.

Or for 10 minutes work retap it. Where abouts are you? I'm on my phone and can't see. If your local to me il re tap it

Does it actually tighten or just spin? have you got a washer on it?

If the threads are bad enough for oil to leak past re tapping it will not magically bring the metal back. You could retap to the next size up, but you will then need a new sump plug as an ordinary bolt won't do. If you're handy with the tools I would buy one of these and weld it to your sump. This is what we use and it works every time.

I've got boxes full of sump repair kits and helicoils however I usually use timeserts. Expensive but do a cracking job.

Never used a time_sert myself so cant comment on those but wouldn't use a helicoil unless I was selling the vehicle.

If you do them often I'd advise having a look in to them. A lot stronger than the original threads. A helicoil wouldn't even come close!!
