MHG versus standard (7m-gte)

[EldarO]

with all of us flocking to team BHG, it was only a matter of time before they ran out of stock and had to make more, might as well improve on it!

Ive had success with this goo before. its good for 200degrees C and 300psi

I'm Curious as to what this goo is called.

[whatthe?]

The problem Ive seen with factory gaskets (even when torwued properly and gooed) is that high boost will still push them away from the bores due to the soft material theyre made of. The one that came out of the 7M in my silver supra hadnt blown, but it had pushed the o-rings around the water jacket openings into a funny shape and the big o-rings around the bores were decidedly eggshaped.

The goo is made by Dynatex, Its the sealer #2 product, whatever that means.

Guess they just use numbers to distinguish.

Will be hunting it down in the next few days.

Fit a MHG from Cometic tripple layer have have and deck check for warpage and clean up manchine accordinly and then throw on a set of ARP Headbolts $160-$170. You will never have trouble again chech water pump thermostat hoses radiator condition radiator cap condtion hoses and metal pipes are not corred and thermos and fan working and no belt slip and check condotion of water temperature sensonsor two in front of powersteering can and one on of thermostat and one below theromostat. Check for head condition not har or soft no obious hairline cracks in water galleries and this should see back on the road.

hey guys how much torque can standard oem bolts take? cause if i take my oem bolts out and replace them with my arp bolts wont that ruin the hg due to pressure no pressure then reapplied pressure?

I'm running standard bolts at around 68ft/lb I think. Pretty sure they are good for up to 75ft/lb, I just didn't want to push em too hard.

[EldarO]

i put em at 80 ft/lbs.

[Yian]

I think I torqued it down to just a touch over 80. Couple more ft/lb for good measure

[ma61turbo]

Hrm, I might have to torque mine down some more then!

[doobs]

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

Doobs

I did mine exactly the same as yours.

ARP studs with a standard gasket.

Mine is an NA engine and I have also had no probs.

Makes you think its not the gasket but the fasteners.
