My d16y8 just recieved a new head gasket and resurface. Problem is when i pressurize a cylinder i get air in the coolant. Im almost convinced that block must be resurfaced. Any input is welcomed.

Do i need to dissassemble the block to have it decked?
should i resurface the head again? 1,000 miles since done last.

block may be warped, and yes it needs to be completely torn down to resurface.
could have a cracked cylinder too. or the head may be cracked

Thinking a crack would cause a leak from 1 or 2 cylinders, not all 4

Have you heat cycled the head gasket? Or is this before running the engine even once after the install?

theres 1,000 on the new gasket

Thank you. The way your post read, I and possibly others can't tell if you were pressuring the cylinder immediately after install or after some use (heat cycles) and discovering the reoccurring issue.
