So...Anyone have a how-to for the LNF..........?

 

uh-oh

 

In for story

 

agreed

 

heard about that after I got home from the cruise, bummer!

 

How'd you blow the HG?

Procedure is exactly the same as any other ecotec motor. Remove piping and manifolds, valve cover, front timing cover, timing chain, head bolts, lift off head.

 

That sucks man

 

not hard, just time consuming, get yourself a set of ARP studs tho

 

Also when putting the head back on remeber inside out, i'll try and find the pattern chart for torquing

 

its a constant circling, like that game snake lol a spiral torque sequence

 

head torque specs?

 

Make sure you retorque the head if you use those... Most people don't.

 

How-to anyone?

 

How did you blow a headgasket?

 

you tell us how u did it, then we will tell u a how to. what u think u get free advice on here?

 

There is a procedure to torque to spec + 1xx degrees that will dial you in at the correct torque after stretch, thus not requiring retorque. However, high horse engines should retorque REGARDLESS.

 

i did an additional 70 degrees, as that is what they instruct you to do

 

good deal. fifteen years ago what BYT said would absolutely be true, but technology and heat treatment practices and lots of testing have come to the conclusion they can nail down the correct clamping pressure right out of the box.
