  • 9n ford engine sleeves
  • is it possible for the sleeves to sit to far down in the block and not seal the head gasket? I have overhauled this engine and am getting antifreeze in the cylinders. The block was decked an head was milled. Is it possible that i got a bad head gasket even tho it is new? possibly leaking thru studs that go in the block ?

  • I decked my 8N engine with new sleeves installed and have had no problems. I was careful to chase the stud threads in the block with only a plumber's wire brush for 1/2" pipe before reinstalling the studs. I used Permatex Aviation Form-a-Gasket to seal them and only torqued the studs to 10 ft-lb in the block. Also used the Felpro soft head gasket, not the metal one. Can get those at NAPA.

  • Steve,I would drain the block and remove the studs double nut them to remove one at a time.Coat the threads with some Permatex Aviation Form-a-Gasket and replace them.Then re torque them.Refill coolant start and check for leaks.Before taking the head off again.

  • Sleeves shouldn't have anything to do with sealing water, even if they were somehow set too deep. A cracked cylinder head would allow water to get places it shouldn't be, but that should have been found before they did any machine work on it. Studs or bolts that go into the water jacket do need sealant on the threads.

  • I generally use Permatex Blue for water jacket and Black for oil.
