Why he felt the need to parrot his same old drool when you had already
mentioned having the heads checked/reworked is anyones guess.

No you mean Neil is the bird brain. Head gasket do not just fail for
no reason and if you think they do you are a bird brain.

The OP realizes that genius, that's why he stated in his first post that
he was going to take the heads to a machine shop and have them checked.

You just like to be a troll and cause trouble. I was telling them SOP
of gasket repair.

Do you not read what people post, or is it just a lack of comprehension?

Yes I do think you lack reasoning and comprehension...

Ah, the infamous 'I'm rubber, you're glue' defense...

You going to deny the plausibility of the computer programmer had a
leaking intake gasket and ran the coolant low resulting in what is now
SUSPECTED to be a blown head gasket?

I highly advise using a Fel-Pro MS98002T intake manifold gasket set on
this application, this set is a better design that addresses the
inherent weak spot of the OEM manifold gaskets which were very prone to
failure. (and may well be the root cause of the overheat)
Also, keep the injectors wet once disassembled; when you disconnect the
fuel lines at the left rear corner of the engine, cap the lines on the
manifold side. If the injectors are allowed to dry out, there is a very
good chance that they will stick and cause a misfire.

There was a design defect with Intake gasket that GM rediesigned in
late 2005.

GMs redesign sucks. The Fel-Pro gaskets are much better.

New design is a lot better

So the product quality level of 'sucks' is OK with you. Hmmm....

It effected the 4.3 and 5.7 Vortec motors.

The defect effects ALL GM V engines. 3.1, 3.4, 3.8, 4.3, 5.0, 5.7.

Not really but then a Troll would not likely know this. The reason
there was a big problem with 4.3 and 5.7 Vortec motors is because when
GM went from TBI to MPI thay changed bolting of intake to engine
(example on 5.7 they stopped using center 4 bolts to secure it) and
the manifold flexed more in heating and cooling cycle and strained
gaskets plus GM used a cheap plastic design for a while too. Intake
gasket problems with TBI engines where of a different nature and 3.1,
3.4 and 3.8 where not as troublesome because they were not based on a
modified 40 plus year old engine design.

Yeah... that's why the other V engines suffer internal coolant leakage
at the intake gaskets, because they want to be just like the Vortec
line. Everybody offered a plastic design on those engines "for a
while". So, the 3.8 isn't based on a 40 plus year old design?

I personall had
one fail on my 2000 5.7 under warranty at 29K miles and again out of
warranty at 38K miles. They fixed it for free out of warranty and
promised me that if it ever leaks again they will fix it for free.

IOWs, you've never done the job, even on your own truck.
<snicker>

Actuall I have rebuild a lot of engine and valve jobs and intake
gasket changes but why change it when GM will pay to have it done?? Is
this a Troll thing? BTW, I was planning to change mine when GM offered
to do it for free and free repair if it ever leaks again and only a
foolish troll would pass that one up.

You are a wise man. I wouldn't want me working on my own truck if I
were you either.

They said last repair had new gasket style. BTW truck only has a
little over 42K today

Good luck with your project.

You will need good luck if you follow Neils advise and do not varify
that heads are flat.

Hey ***, where did I tell him not to verify that the heads were flat?
(use all the screen space you need to show the citation)

tisk tisk, Troll loosing temper. Remember you started this not me....

What did Neil start?

That head gasket is clamped between to big pieces

You mean 'two' big pieces?

I guess your troll brain get lost here and cannot rationalize that the
block is a big piece of cast iron and so is head.

I guess you are *too* stupid *to* realize that you mispelled *two*,
hence his response.

of cast iron and the only way it is going to block is if one of the
surfaces warps and changes pressure on it. (or you supercharge it on
over boost engine a lot too).

Gotta love these tangents you go off on...
Supercharged?? W-T-F?

Another Troll responce, I was stating the reason why they fail in
service. I dod not say he had a super on his. I need to remember when
you talk to a Troll you have to keep it simple sometimes.

Also remember to go on ridiculous tangents about supercharged 4.3
problems.

SOme time they can warp with heat and
straight out with they cool but NEVER change a head gasket on any
engine that has blown one without check head for flatness or for
etching from hot gasses after it blew.

Yes birdbrain, this should be mentioned six or seven more times, even
though the OP knows to (and has stated that he will) do it anyway.

Yes I am sure he sees who has a temper problem here.

I'm rubber, you're glue... looks like it's you again. No backs!
