Re: New Head Gasket Seeps Antifreeze

Troubleshooting 101: Eliminate the obvious first.
Changes: head, washers, different gasket than original, condition of the parts.
Any time a possibility for mismatch, check and recheck the fitment.
Verify the gasket fits the block and the head and has the right dimensions. Recheck the head to block fit. Examine the gasket to see where it compressed or did not.
Also, where it leaked should tell you the path of the fluid, how it got from the water side to the outside or inside. Concentrate on those areas for fitment.
Then go to proper sealing techniques.
Depending on the washer hardness, making it thicker may require more torque if the washer deforms more. Use at least same grade as the nut, grade 5, preferable 8. If you used low grade washers or made from soft metal they may not transmit all the torque properly. What you read on the torque wrench is the force applied, not what the force did or how much actually went into tightening.
