Headgasket still weeps, front of engine.

Yes, I am working on a hydro motor.

I agree ARP is the way to go, but am not entirely sure this motor will be in the car much longer. I am thinking TDI to this car.. OR taking the T bits from the TDI and putting them on my 1.6 for now??

Its up in the air..

BUT yes to the warm half-turn??

My book gives that as the sequence for the triple square head bolts (somewhat different for the older socket-head bolts). I understand it to be specific to head bolt type and not whether it's a mechanical or hydro head.

Ok, head bolt specific. I have the 12mm triple square.

Warm 1/2 turn is good then?

this is also my understanding. IIRC (no book here right now) the triple square bolts do not require a retorque after 1k miles. Only the 6pt bolt do. FWIW, I have ARPs on my car and it leaks. FML.

Triple square do require 1k mile retorque. Let's not let this get into a confusing mess. What I posted earlier was direct from the Bentley.

To 8VOF: I would give it that extra half turn. I think that as long as you aren't seeing any combustion pressure into the coolant, you should be OK on the gasket seal. Half turn in one continuous motion is a bit much. If you have to break it up into smaller turns, I'd probably do (2) quarter turns, each in a smooth, continuous motion as the Bentley requires, while following the standard torque procedure between each quarter turn.

The book right here says, MF and ME require an additional 1/2 turn at 1k miles.

Also, I thought that all hydro heads have triple square bolts anyways.

Not trying to at all. Thanks for the clarification :thumbup:

Apologies if that came across even remotely rude

6pt bolts require a re-torque because they are re-useable non-stretch bolts.. 1.5, and early 1.6Ds were the engines to come with these bolts..
