Be sure to drain enough coolant out of the radiator to get the level below the top of the block. Don't ask how I know. :roll: :roll: Close to 10 years ago, I removed one weeping head bolt and reinserted it after putting sealer on the threads. No problems yet. For several bolts, I would get a new head gasket and start over. I've been known to be overly cautious about some things. :) :)

I would take them out one at a time, goop them and retorque. Should be OK.

My "cautious" approach would be:

1) Drain the coolant below head level.
2) In reverse head tightening sequence, crack each bolt a little bit.
3) Same sequence, loosen each bolt to barely snug.
4) In head tightening sequence, remove each bolt, clean up, apply sealant, reinstall to slightly snug.
5) Finish torqueing all bolts by the book.
6) Top off coolant.
7) Warm the engine and retorque by the book.

True caution would be just replace the head gasket after loosening all the head bolts.

Well at this point I might as well get a new gasket and do it right , because I spent all that money on rebuild , just not very happy about such a dumb mistake

Don't beat yourself up, we have all been there. All to often, in my case. :oops:
