this vehicle is precious to me...
Check out that site. there is a few vids there. Yes they are expensive
yes they are 100 times better than a "helicoil" ( i don't like them a lot)
can get them in stainless whitch is a bonus in water systems.
helicoils come out sometimes those don't. Exellent for all the alloy bits especially on bellhousings.
I reguard series good series 1 blocks precious too.
Ah my mistake - I thought the repair in question was to the water pump flange!Quote:

Apologies all,

no, that was sarcasm. which is why we need a sarcasm font, kinda like the correct tension for any bolt is to do it up till it snaps then back it of half a turn for thread relief.Quote:

I'll see you tomorrow at 1.00pm Dave - and I certainly appreciate your help. I need to educate myself some with all of this, but I do trust your judgement in the meantime! :)
I'm hoping Google will be my friend.
What an amazing journey this thread has been - good thing I haven't mentioned the fuel pump! (only joking!) :p
I'll demo a helicoil for you tomorrow in some scrap steel along with some other trickery that you might come across later on.
WOW, what a debate
helicoil's cheep & easy and no where as strong as original,
There place and where I tend to use them is in aluminum where assembly and disassembly would be done often.
Welding up and re boring then taping is always the first choice PERIOD. But this depends on material and position. A cast iron block and a vertical working face is not ideal. It is what I would do BUT is not in reality with in the skill set of many today.
2rd option is just go oversize, BUT there may not be enough supporting material surrounding the original to do this.
In that case I would still bore and tap over size then flush of a bolt, grind of the week point and weld it up. Then bore to original.
Again out of the skill set of most.
Now as most solutions require over boring and this includes helicoils and as I pointed out there can be some problems with this. so lets look at the different sizes actually needed.
i believe the original is 1/4 BSC which sounds correct
We are more interested in the dia of the bottom of the thread rather than the over all dia. or the boring size.
1/4 id .201 od .266
6mm id 5mm od .2362
5/16 id .257 od .332
so we can see that 6mm is a bit smaller than 1/4 and that 5/16 is a natural size for a striped 1/4 thread. a 5/16 would give a full clean thread.
now helicoil's
1/4 od .375
That means that the largest cut diameter for a 1/4 helicoil is greater than a 5/16 which begs the question of why use a helicoil when a 5//16 will do. That is assuming that the shank size is not an issue but then why use 6mm when the shank size is smaller than a 1/4??
As i originally posted, its just un-kosher
done and dusted, split the deck and pass em out, its delt with.
Matilda rolls on under her own steam, well without the steam so much now the cooling system works.
:TakeABow: Quite right! :D As Borat would say, "Great Success"Quote:

We wanted to flush the block without circulating the gunk through the newly rebuilt pump, so....

Wooden cutout plugs - I'm keeping them - along with the inner tube tyre gaskets we fashioned....
Here is the Man himself - flush successful...

So then in came backup in the form of Killer - he did the Helicoiling and then we rebuilt the cooling system - just to prove I did more than just order Pizza.....

Anyhow - Matilda is up and running again - no leaks, it's all good. Actually Dave - that bottom radiator hose that was slightly leaking - I hadn't done up the hose clamp! :blink:
And this thread is late 'cos I've been driving my love all around Ipswich :wub: Thanks everyone for your help along the way in this crazy thread - and especially Killer and Blknight - you guys are true gentlemen.
I declare this debacle OVER! :D
now I know that in all the hectic production work and insult slinging I may have missed something...Quote:

So the saga of the water pump comes to a close, What are we going to look foward to reading now.
This would have to go down as the longest water pump repair that I know off.
