You will need a new headgasket.

You will need new headbolts and rocker bolts, they are all TTY, so they shouldn't be re-used. I would replace the LIM gaskets for cheap insurance too. Generally you will break the LIM coolant elbow, so get one before you start, you'll thank me for that one!

A MASSIVE torque wrench too. IIRC 130 ft/lbs plus additional 90* You better have some ass behind you when tightening these down...

 

[J.E.T.]

About $250 in gaskets/bolts/sealant/fluids if I remember right...

i coulda swore it was something like


70* to every bolt...


then 80*....

then 90*

Definately not. Yes there is a specific pattern that uses ft lb increments for studs, but there are no increments for bolts. Also, there is no incrementing of the * of extra pressure.

what headgaskets are you going to use

I'm just trying to see how much is involved in tearing off the heads I have to replace my lower intake manifold gaskets because I had one of them start leaking about a week ago.
I was thinking of pulling the heads so I could clean the carbon off the pistons.

I'm pulling about 55/65kpa at idle when my car usually idles at 32/33kpa big leak eh? I'm not really sure I WANT to pull the heads.. ignorance is bliss eh :lolsign:

the aluminum LIM gaskets will never blow. its a nice upgrade
they are about 2-3 times as thick and ive run some high boost and not blown them

How do you know how many kpa your car is pulling at idle? I'm trying to track down the main reason of my running sickly rich, and think it might be a lower intake manifold gasket.
