Hi guys - got my rebuilt B20B ready to crank last night and noticed a steady trickle of water the whole way along the inlet side of the head after I had filled it up.
I followed the green book - 61-69 lb. ft, however I have seen other quoted numbers of 80 lb ft - or a TTY of 13/43/90 deg - what do you guys torque down to?
The head gasket was supplied in a full gasket kit Durapro GSFH450D unlike any I've used before it didn't seem to have steel in it around the bores etc - and it was certainly different to the one that came off in construction, but same thickness.
Any tips would be great, thinking if it's categorically not torque spec I will pull the head off tonight and clean and reuse the old HG and see how I go, but I'm hoping it's just under torqued as it was very uniform in how it dribbled along the gasket!
Thanks
Mick

What were the specs supplied with the durapro gasket?

Good point had my head in the factory manual I don't recall seeing a spec sheet in the pack but I'll check

Mick - one thing some folks forget is to put the 'o' ring on the water pump where it meets the head.
Torquing the head is done in 3 stages -
#1 before fitting rocker gear, 29 ft lb
#2 after rocker gear is fitted, 58 ft lb, then set clearances
#3 = 69 ft lb, after 10 minutes running, then re-check clearences

Also adjusting the height of the water pump to meet the head catches out.
I wouldn't have used that brand Hg, elring b20e Hg is best with modern fuel.
