torque headgasket questions.

holler Northernwestern;

it's right- if i re-torque the head gasket on EA82 or must one time torque? because of my ea82 wont starting and stuck, there have a some water inside cycle from spark plug (spark plug had a wet on it) because of i was re-torque make the gasket wont let the coolant into?

my head gasket is Fel-Pro

 

Step 1 nut- 22 ft lb

step 2 nut- 42 ft lb

step 3-9 nut- 47 ft lb.

i have a Haynes book.

it's right torque ft lb for my head gasket replace?

please help.

No-you don't need to re-torque the felpro 9392pt gasket's. I do a final torque of 52 ft. lbs. Follow the sequence. And, search the subject. It's probably the Most documented subject in this forum.

like he said - one time on the fel-pro's (that's their advantage and why we recommend them) and a final torque step of 5-10 pounds more is common. sequence you posted looks right off the top of my head, i'm sure it's listed here.

 

sounds like you have a problem - coolant in combustion chamber? the intake manifold gaskets can leak into the cylinders as well. the aftermarket ones are usually really cheap flimsy cardboard. the Subaru OEM intake gaskets are much better in this case.

Don't even think about using anything But the OEM gaskets on the intake. This is a Junk, felpro one with about 4 months on it.

ok, thank you.

i did take off the head cycle block, cam shaft block, valve cover for now. tomorrow ill going to torque on the head cycle block without re-torque.

i did put on the rubber seal on the intake manifold without gasket, it is ok for it or have to but new gasket for intake manifold?

thank for show photo and message.

message back.

Consider this:"

EXCESSIVE bolt loading will cause problems. Many backyard mecanics think that if 50 Ft. lbs of torque is good then 60 is better. In fact dynomometer testing has shown that less is best in most instances. Indeed extra horsepower maybe gotten by being "torque frugal". Why??? The more torque that is applied onto the block the more chance of distortion. This distortion is usually seen at the weakest places at the narrowes point of the bore and at the top of the cylinder. At the top of the cylinder where the compression pressures are always greatest any excess distortion will nullify any benefit of that extra clamping force. Blow-by of gasses will cause premature gasket burn through and less horsepower. "Less maybe best". "

Unlike the EJ, the EA-82 doesn't have headgasket problems, outside a good reason.
