Sump plug stripped

Postby JustSharon » 01 Dec 2019, 18:25

Hi
Changed the oil last year (universal sump - 2 drain holes) slightly stripped the hole.

So, in prep for Les Comes... Do I drop the engine protection and try to helicoil m14 x 1.5 in situ or do I drop the sump off?

Or who wants to come round and do it? Be warned though as there are a few minor jobs aswell to do - like a bearing and stuff :)

Use a time sert. Far better that a helicoil.

Thanks Russel

Okay, same principle as heli coil but a dam sight more expensive. How can I use a time sert without the expense?

Yes it is more expensive but it is permanent and stronger unlike a helicoil.

Get an over size sump plug kit , no time sert or helicopter, just a slightly larger thread

Timeserts ...hmm. Stronger than a Heli-coil they may be but unless installed dead square to the original sealing face, it will still leak because the land for the seal is quite narrow.
Had to correct one on a wbx recently, no choice because it had been done with a spark plug thread insert!

Isn't that M14 x 1.25 rather than M14 x 1.5 ?

I recently used some "US Pro" thread repair inserts for a glow plug, like Timesert, and the fitting kit came with the repair pieces, which isn't the case with Timesert and their fitting tools are expensive.

I have to say they worked well, but I couldn't see any in M14 x 1.5 to recommend, only Timesert / Helicoil type available ?

Correct, hence no option but to put it "right" by making a guide bush from another spark plug, screwing that in and using a spot-face cutter to shave back the aluminium until it met the (hardened steel) TimSert.
At least then the correct size VW sealing washer will be evenly clamped and not weep....

Sorry Sharon, gone off on a tangent (again...)

Drop the sump off and get it done by someone with access to a big pillar drill or a milling machine.

Best results and no guesswork!

Thanks but no, if it gets stripped again in the future then basically the sump is foo barred, prefer to stay with original sizing.

Never noticed you go off on a tangent Ian!! 8)

So, time for me to very nice to big pillar drill owners with a timesert kit and get this sorted?

A time sert or a heli coil requires a bigger hole drilling than a 1mm over sized plug , an over sized plug gives the possibility of a new plug and you can still time sert, one time sert go is all you get at that size
