I am getting ready to instal a reman'd head on my '92 2.3l. The instructions make a vague reference to the use of thread sealant for bolts passing through oil and coolant passages. This is not my first head replacement, but it is for this engine. I've never seen the use of thread sealant on head bolts before. Could someone tell me what kind of sealant I should use and on which bolts?


TIA.
