MHG versus standard (7m-gte)

[doobs]

Makes you think its not the gasket but the fasteners.

I hope so fella

Ey all,

At the moment I'm running a stock gasket torqued down with ARP studs to 84ft/lbs (what ever was in the ARP guide). While installing the gasket I had the head skimmed, cleaned the block as best I could, and ensured it was flat. I also had the head tested for 'hardness' and it was fine. I used hylomar spray on the gasket...
I retorqued after first heat cycle, after 500kms not boosting at all, and after 1000kms with basically no boosting, then took it easy for another 500kms...
I'm running 9psi now and have for a while, the car has almost clocked over 8,000ks since the gasket change, touch wood its ok...
When I rebuild it, I will be putting a MHG on it...

Cheers

you shouldnt have any problems, just make sure the cooling system is up to scratch, as you would any car, and give it its proper run down time after a hard thrashing, and it'll live for ages.

You have sooooo much more self control than me!!!!

Mine with the full rebuild saw some hot temps cruising around summernats and I had no probs.

The car saw over 100 a couple of times. Seems good I'm not to sure it would of been right with a standard gasket

Mine sits around 80C to 90C in normal city driving, regardless of the ambient temperature... if I give her a constant hard time, it might get up to 95Cish, until I slow down… The hottest my car gets is if I turn the car off on a hot day, it sits at around 100C until I turn it back on...

Bit of an old thread, but I wonder how you got along finding some of that Dynatec Sealer #2 ?

http://www.toymods.net/forums/showth...t=decking+head

Looked on their website, and now they are doing gasket products but couldn't see if any were equivelant to what you used ?

If anyone knows what the current standard is, let us all know ??

i am about to do a hg, gonna use a std toyota hg with arp studs, where can you get them for 160-170 (AS posted above) i have seen them CHEAPEST $220ish!

my car has gotten to mid 90's on my aftermarket gauge, even after a thrashing, it doesnt get to 100, ill clean the entire system again once i do the hg though!

i have heard 74lbs/ft is fine and anything more than that is 100% unnecessary! std 58 obviously didnt work, stupid toyota, you think they would of done a recall after a few years!

[Wildsupra]

Na i never managed to find the dynatec sealer #2 i once used. Who knows wot happened to that stuff, it was probably toxic and was banned like so many other excellent products that actually work

Woggin, those prices were almost a year ago when the exchange rate from usa was ALOT better than now.

[Wildsupra]

sorry my mistake, almost 2 years agao heheh

[gixer]

How about a spray of Hylomar on the gasket, that stuff usually works a treat.

[Wildsupra]

yeah its good stuff but doenst really combat the 7m issue entirely

[hosking1991]

hey guys im in the middle of a 7mge bhg fix

It blew between 5-6 cylinder

Now the head and block is as straight as the day it rolled off the factory floor

I will deck the head and replace the stem seals and it needs welding to one water jacket easy fix

Should i spend some money on decent head bolts for a stocko 7mge?

And what should i torque the head to? the vrs kit i have here says 56 ft pounds

thanks luke

[woggin]

56lbs/ft will make it go pop again, most people do it up to about 74lbs/ft, sum go higher, but isnt really needed!!

forcefed has bolts/studs for sale for $212 i pm'ed about the prices (economic downfall may have affected them) but i will put studs on my 5m once i fix the bhg, then boost time!!

modyourcar.com also have 7m head studs for sale, its a ozzie based 'fully hektic' website, run by lebos!

wog

[TheStitt]

why boost a 5M???

[woggin]

iam thinkin of it, not 100% on it yet, have wanted to do it for a while, first 5mgte without BHG! considering it, if i can find a 7mgte, cheap, thats in good nick maybe ill do that, or ill just save up and buy my bros jza70!

[Wildsupra]

why boost a 5M???

not much different to boosting a 7m...gunna have the same issues.....the yanks love doin it
