Hello all,

I need to put a helicoil into my sump drain hole (stripped by previous owner & dodgied up) on a 2.1 wbx engine. 😠

A helicoil kit is $110 which includes 5 helicoils & tools to do the job, I am looking to share this kit around to help others out &/or share my expense. 🤪

I am looking at "sharing" for the cost of a "helicoïl" (about $3.50) + a little bit of tool cost ($5) + postage (depending on where you are but $5 should cover most of aust.) then you send tools back to me.🤓

Then of course we could put this in the "AVD tool register" so its available to all users.

What do you think? Any interested parties? Or am I dreaming? 🙅

Or.......... is there someone out there that has already accumulated on of these little treasures that they would be willing to farm out for a similar deal?👍


Must be someone other than me that has a dodgy drain hole.😂😂

This will only really interest people with WBX engines or Type 4 kombi engines. Type 1 engines you'd just replace the sump plate.😘

Cheers
Brendan

I think you should look at the Time-sert version instead

Don't use a Helicoil Not suitable for a WBX
you need a Time-Sert
As suggested
Any Good Vw shop will have em

Seen him this arvo mate, no luck.

Looking at time serts as well Barry, its just that helicoils are more ready available. ATM.

If you can hang off until tomorrow Brendan I'm going in to the old work so I can see what's there in the Timesert box. If not, there may be an M16 x 1.5 tap there you can have to tap it oversize to use with an oversize plug.

From personal experience most of them leak because they are crooked or the coil screws into the case leaving a bloody big hole,go with the time sert. Cheers Les

if you fit a helicoil in alloy then you will have more problems

just use a time-sert as you have been advised


without going into
the reasons why
as info posted here is often misinterpreted

It would appear that time-serts are the way to go.

Price however has dramatically increased....... time-sert kit containing 5 x inserts is $325.

Anyone know someone that would be willing to lend this sort of thing out?

My opinion for liking the timesert type over the coil is purely as a end user.
I have had both put in various engines and looking at a time sert it is an actual "thing" with a thread (thats a technical term 🙅 ) that screws in where the damage is

I just struggle to acept a heli coil (a spring like thing that is dependent, if i am not mistaken, on the damaged hole) is a better device.

Not saying it cant work - i would just like to know why it is better than a time sert.
I can see the opposite reason

A thread insert doesn't go into a damaged hole! It goes into a brand new tapped hole which is either in a stripped thread or a new assembly from new. They are very good where a fastener is to be regularly removed and replaced but are actually stronger thread wise than being just the tapped thread in alloy parts. Remember that we have to stick to the rules of how much length of thread compared to the diameter of the thread. THAT is why any thread will strip, especially in alloy if the same length is used as for steel or cast iron. With alloy, it's best to be at least 2 x dia thread length.



BRENDAN. I have an M16 x 1.5 tap if you want to open it out to use an oversize plug. I'll pm my phone number so you can give me a call later on tonight. A lot cheaper as it'll only cost you a Toohey's old at Nambucca!!😂

i would use a heli coil over an insert type plug any day of the week, but i am guessing that your motor is still in the car so the problem you will have with a heli coil is that you need to snap the small tag off the end and there is a good chance that it will end up in side the motor ( not good )

tapping the case to 16mm would in my opinion be stupid

Why are these heli-coil kits so expensive? Is it just because of the large size or what? I heli-coiled the sump plate holes in my Beetle engine case, with the motor in the car, and all went well. I was able to retrieve the snapped-off tang without losing it in the motor, and all went well. The helicoil kit certainly wasn't anywhere near $110 though, it would've been under $50.

maybe because you used a 6mm helicoil

What size is it tapped to repair with an M14 x 1.5 Timesert?? That's right! M16 x 1.5 . The actual OD of the tap is 16.104 mm! A Timesert with original plug or M16 x 1.5 with oversize plug...... why??? Because we can 😂 but most definitely not stupid. 🙅

Also with the Timesert the length of the insert must suit the material thickness otherwise the "threadflow" tap for installation may not lock it in place correctly. Don't "just get a Timesert" of any length.

Tap it to 16mm , use a helicoil
have the helicoil damage the thread when someone changes the oil
then what ? tap it 18 mm ? 😂

A 16mm sump plug is also IMO stupid

I like things to look original.
not dodged up or

We are here to help Brendan fix a problem, not argue if something is stupid or not! Whichever method we use.... Helicoil, Timesert or oversize plug is individual choice. I have given correct engineering alternatives to a problem created by either a heavyhanded previous owner, likewise heavyhanded motor mechanic etc.

You supply him with the Timesert and tap and installation tools to help a fellow veedubber out OR I'll supply him with a standard M16 x 1.5 tap and the plug to suit, regardless of you thinking it's stupid or doesn't look original under the engine where no one will see it.

Signed by the Engineer.❗

I did not say that I am a mechanic 🤪

My qualifications were not stated.

If u read the post you will see that what I meant was if u use a 16mm plug the mechanic or whoever does this has signed the job or left his mark.

Anyway I am too far away to do the job and I don't lend tools

I was just telling him what is the correct repair for his WBX

if you are going to use a heli coil dont tap it 16mm make sure you use the correct heli coil tap.

if that heli coil does get damaged in the future, no dramas pull the coil out and fit a new one you dont have to go bigger.

After careful consideration of all the above advice I have decided to (at this stage) make do with what I have currently (plug not yet fully stripped) & jerry-rig a failsafe over the sump plug until I can thoroughly look at all of my repair options. I am a qualified machinist / toolmaker (although now working outside my trade) & up until I posted this idea on here, would not have had any real hesitation using a helicoil repair. my only real concern was making sure it went in square to ensure a seal between plug & seat.

Its funny how a simple idea can quickly turn into a my ways better than your way, your right I'm wrong type arguement. Well thats how it appears to me anyhow.

Thanks to all those that have provided meaniful input.

I take it that no one else is interested in a M14 x1.5 helicoil ???????

Dallas, I'll return your PM shortly.

Cheers

👍 Ok mate. Good to see another Toolmaker amongst us! Pity I'm only back part time at TAFE now otherwise the Fitting and Machining section would own a few metric fine series Helicoils and Timeserts as well!! But then again, maybe they still need some....... M14 x 1.5 may get on the list tomorrow!!
