i pulled my a12 head off because i have a blown head gasket and im just wondering when i put it back together just wondering how tight to do the head bolts with the torque wrench thanks jarryd

if i remember rightly it is 44pounds... ill have a look in my manual right now for ya

sorry dude couldnt find it but i am pretty sure it is 44pounds,,, the wiki should have it in there aswell

is that 44 pounds with a hammer popo?

It depends on which head bolts you have.

Early A12s have one torque figure, but those with the updated head bolts can/should use the higher torque specification. This will help prevent blown gaskets. The better bolts have "13" on them.

The specs are:
A12 33-36 ft-lb 4.5-5.0 Mkg (to engine # A12-470084)
A12 40-43 ft-lb 5.5-6.0 Mkg (from engine # A12-470085)

Possibly A12s after 1973 might be even higher torque -- anyone have the specs for say a 1978 A12?

thanks mine is an 82 model also should i use a type of gasket glue when i put the head gasket in i have hylomar gasket jointing compound but just unsure its what autobarn recommended

i thought ity was always recomended not to use any glue/sealant on a head gasket

Yes, it is recommended not to put anything on a A-series head gasket.

By the way, 1982 A12A head bolt torque is 51-54 lbs. I suspect the 1982 A12 will be the same, as it is virtually the same block.

a mate of mine owns a head shop and recommends using copper coat on every head gasket i use it on every head i do and never had a problem including my s/c a15
just my 2 cents worth
