You know what I say to that.

studs are in

one of the stud holes on the right bank toward the rear had semi-buggered threads though, I chased them and the stud is in but I'm not hugely happy with how it felt going in. Fingers crossed it holds the torque...

Now would be the time to put a helicoil or Timesert in. Big PIA later.
Better safe than sorry...

odd thing about that... the closest tap I could find was 12x1.5. The thread pitch looks right but the bolt just feels 'loose' for instance running the stud through a die. Certainly not SAE and 10 is way too small. Just my imagination? Can anyone confirm that the holes are M12X1.5 ?

You're right though, I should helicoil.

ETKA should say, I would check but I don't have it here.

negative on etka, doesn't list the thread size.

Dear Santa...

Nice stocking stuffer! Many of us could save hours with one of these for sure!

Pretty cool tool

I hate bringing a bolt to the local Napa and asking the thread pitch and the guy gets off his stool like it is a HUGE chore

Marc, how did it feel coming out? Was it funky or did it come out fine? Basically you are saying that the bolt feels a tiny bit too small for the threaded hole? If you are going to do a helicoil, now is the time.

the easy thing to do is probably just to call ARP, give them the part number and see what they say...

according to Tacoma Screw it's a M11. i got one from them. 8 bucks.
Took down the head bolt. took a bit to figure out.

11mm? WTF audi. sheesh. That would make sense.

CANONN90QS · Post by **CANONN90QS** » Fri Dec 12, 2008 1:33 pm

yea. the guy was pretty helpful but was a little blown away that it was 11mm.

Post by **HT Motorsport** » Fri Dec 12, 2008 5:40 pm

Nice like the M7 studs in the valvetrain. Good one Audi

Never mind... this POS does not have M11 thread checker! I'll have my usual lump of coal instead... :x

11mm helicoil installed so all is well there. Went to go fit my headgaskets and realized my sealed victor reinz gasket set has two right headgaskets in the kit :curses:

Sigh.

ugh...... where did you get the headgaskets? victor reinz problem or shipper problem?

The set was sealed, so I'll guess VR problem. Doh.

aren't you stacking gaskets anyway? Just get two left ones

Post by **Marc** » Tue Dec 16, 2008 3:56 pm

yes. And I bought an extra left and right separate... So now I have 3 rights and one left...

Weird.....just t did a quick check of the etka, and it show them being the same left to right for the pt, but two separate numbers for the abh. Any idea what is different Mark? Pics?

cuatrokoop · Post by **cuatrokoop** » Wed Dec 17, 2008 10:11 am

Correct, they don't have the normal 88mm bore spacing That was the only way they could get the larger pistons in IIRC.

Jonathan · Post by **Jonathan** » Wed Dec 17, 2008 10:50 am

So, the bores are in a zig-zag pattern, like the VR but to a much, much lesser degree?
