Oh the sweet, sweet smell...

[Saavedro88]

Of a BHG...
:cry:

This is the first time I've ever smelled the coolant btw... The first rebuild was for rodknock, no BHG.

I'm so pissed... Freakin Cobalt... I didn't even win! But mostly I'm pissed at myself... I don't even know how this happened...

So I need some opinions, I've been wanting to swap in a GTE for a while... Should I just do that? Should I just rebuild with a turbo kit for GE-T?

What can I do to make this NEVER happen again??

[s383mmber1]

Dont be madd about a head gasket, you can change one easy in an afternoon....

If your a GE, stock headgasket with a milled/straight head and clean block.

If your putting in a MHG the block and head have to be machined.

[suprarx7nut]

I"d say if you rebuilt for r/k the HG should be more than doable. Take your time, clean up VERY well and you shouldn;'t have to worry about it again.

It's already been done. I was under the impression that installing an MHG was like, the ultimate invincible fix?

If it's done right, ARP bolts or studs, like 383 said, head and block machined, retorqued?

Thats the 100% wrong way to think about it. Your wrong, anything can be destroyed in an engine at any given time for any reason.

If the heads not straight, itll BHG

If the block or heads cracked, itll BHG

Stock headbolts? Itlll BHG

Many other reasons? Itll BHG

[cuel]

How do you know it's BHG?

1JZ? I kick myself for not having swapped in one when I did my BHG.

[Saavedro88]

No 1j is definitely NOT an option.

When I did the last rebuild for the RK, we installed ARP studs and bolts everywhere (except i think we used Rockfords for the Exhaust manifold), sent the head out to be machined, installed a no name head gasket that cost i think about 150 and torqued the head to I think 92 to try to raise the compression a little...

I know it's BHG cause the coolant is spewing out of my exhaust...

[s383mmber1]

Common man! Dont blame the car for this one.

Over torqueing the headgasket? Why?

ARP has torque ratings for a reason.....

Don't see were you machined the block???

Did you use ARP head bolts or studs??

The studs I believe you can torque to 92 lbs, but the bolts you shouldn't go much more than what ARP recommends, I think it's around 72lbs. but don't quote me on that. ARP sends that info with the bolts.

Oh I'm not blaming the car! I know it was probably something I did. This was my first ever rebuild...

And I used the studs which, Like AJ, I thought I could torque those down to 92?

AJ: I had both machined, sorry...

[ill Z]

Well crap, I used head bolts(ARP) and torqued them to 83lbs. Should i pop open my valve covers and redo them at 75lbs? Car hasn't really been run much at all only cranked up a few times here and there to move it and tune it.

[s383mmber1]

You guys need to search, proper MHG torqueing has been covered more thank a million times on this forum...

Im not saying that overtorqueing the head gasket blew it, so dont think its your problem.

[ill Z]

Alright Seriously? The time I did my install I read several complete rebuilds on the SM forums. The one I followed seemed to be the most technical and detailed out of them all and also coincided with most other's rebuilds. This is why I went with 83lbs on the Bolts. Personally, I have had very few issues after the reassembly which makes me feel extremely fortunate and also tells me the individual who did the write up knew what he was talking about.

Woah calm down there....

I never said YOU were wrong.

But following instructions helps quite a bit...

[Saavedro88]

I wish there was one of those little Lego instruction manuals for our cars, that would be SWEET!!

So was 92 wrong? I should probably not do that again then eh?

[st2b]

When we torqued the 83 with studs, we torqued them to around 75-80. That was a year ago I could be wrong. Then I blew the headgasket because I didn't have money for the Metal head gasket.

It took us about 3 days to do the head gasket, but that was when I was 14 so if you know how to do it it shouldn't be that big of a deal.

Read the torque recommendations for the GE, that's what I would do.

s383,

my bad dude, was not trying to come across as defensive. If I did I apologize. I guess I was thread jacking there just for a moment.

[87nasupra]

did my BHG with stock toyota HG, arp studs torqued to 80 ft lbs. w/copper coating the stock HG. Nearly even compression across the board. Before when i dropped in my n/a jdm,compression numbers was all over the place and i just did a retorque on stock headbolts and stock HG.

Sometimes it works sometimes it don't depends sometimes how old the HG is.

[BlackDynamite]

i put 77ft/lbs on my metal head gasket, arp head bolts, block and head machined...gonna re torque them soon. Seems to be working fine for me.

[suprahooked]

Did you remove the rivit that lays on the block?
Did you have the timing belt rear cover machined?
Did you use rtv sealant at the rear timing cover?
