Heads up to those who plan on running head studs

[libbydiesel]

so actually, the moral to this thread, is if you're going to do a headgasket on an 11mm engine, dont buy the head gasket or the studs, just throw out the engine and find a 12mm one.

It's a sucky lesson to learn but I learned that lesson the same way a few years ago.  After that, I gave away the only good 11mm block I had other than the one that is currently running fine in my rabbit.  If it ever has an issue with the head gasket, I will pull it and install a 'real' 1.6TD or bigger...  Do you have another engine to install?

I have a couple options but nothing straight forward.

See what i want is just a straight 1.6 that i could put my spearco turbo kit on

But what i have is

A 1.6td hydro block just needs put together with new rings and bearings

Then i have 2 aaz heads, which are not of use for this car since i just want a straight 1.6

My dad has a block i could have its a solid lifter 12mm 1.6na block, but were not sure of condition it may need bored out.  If the bores ok ill just rering that and sit my 11mm head on it well see.

I thought the studs would keep me safe from cracking but they didnt and it now has turned into a huge waste of time and money.  But life goes on

How does one go about cracking the block when applying the necessary torque to the hot head?  Shall I freight you my spare 1.6 block?

The 11mm blocks crack if you look at them sideways.

I'm not sure why the 11mm blocks would crack easier than the 12mm.
 Bigger hole means less meat between the bolt hole and water jacket,.. unless they changed the casting to provide more meat.
 How much did you torque it to?
 I use 80ftlbs on my 11mm ARPs, without a problem, so far. Boost spiked to 35 with the incredible back pressure of the VNT, without a problem.
Did you bottom the studs into their holes? They expand at a different rate than the block steel and shouldn't be up against the bottom of the hole.
 Which hole cracked out?

This has probably been asked , is that a fine thread that you are torquing to 80 ft pounds? Cause with the racewares they told me 50 , 60 max. I've never popped a head gasket unless it was my stupidity. I can't imagine the clamp load with 80-100 ft pounds and a fine thread bolt. I'm really suspect of arp's torque values.
