Now i know there has been some discussions in the past about 11 stud blocks and heads but realistically whats peoples views on the 11th stud above the waterpump?

i had the 11th stud leak once blowing the gasket and ive heard iirc on here that the block can be deformed if over tightened at the waterpump end, i am in two minds about having my new block drilled for this

I've had mine done. Carl did mine and I trust his work, so I have worries about the depth of the holes etc etc.

If you are building the engine your self, then take care fitting the studs/head and you'll be fine

My opinion is the same as Andy. I'll be going 11 stud.

If something is worth doing, it's worth doing half of.

I must be lucky as I have drilled and tapped two blocks for 11 stud and I use a lot more than the recommended torque on all the studs - no heag gasket problems so far !.

You should only torque to 25 ft/lb on the waterpump one.

wasn't that because it was not a stud, but a bolt, and not a 3/8 bolt but rather 5/16., hence a lower torque?

if yoy fitted a 3/8" stud same as the short front studs, why still only torque it to 25lbft?

Mine is a 3/8" stud and I usually give it at least 50 lb ft - but I like to live on the edge !

(and I have spare blocks )

Isn't it the 11th stud that goes into the water gallery and you have to use a sealant?

only if you drill it too far,

I thought the idea of doing the water pump on to 25 ft lb was due to it being smaller. I've always done mine all to 45.

Mitsi Evo 7, 911, Cossie. & all the chavs ...... won no problem

its well proven that 11 studs are not required .......... but if you are a real petrol head and need 11 studs by all means, drill the water pump side to 12.5mm depth and NO More! and tap the thread. *wink*

as mentioned i would only use 25 ft pounds of torque here as there is not much meat around that side of the block and the extra Heat off a well worked turbo motor will help to distort this area, rendering the block scrap unless you want a short stroker in the future ?

First mini turbo to get in the 12's & site perv

Herefordshire

My original block was 11 stud, I had another done which was 9 stud by mistake.

On that block I blew the head gasket at 18psi out through the 10th stud would have been.

We then converted it back to 11 and it hasnt happened since.


Thats my experiences for staying 11 studded (no belt jokes)

TBH the first time I used 11 studs it was for the bragging rights and, as I have drilled spare heads and blocks I continued doing so.

It seems that its not usually necessary when the engine put together properly.
