Head Gasket replacement

[alyssa]

I have a 1995 Honda Civic, 4 cyl, 16 valve that had water in the cylinder. The engine ran ok but continuously overheated. At one point the engine would not turn over and I found it to be hydraulically locked. Removal of the sparkplugs resolved the problem (a large slug of water was expelled from the cylinder). Once again the engine would start and run but I knew that I had a problem so I did not operate the vehicle any more (other than to move it around in the yard to keep code enforcement off my back).
I have removed the head. I could not find any screaming evidence of leakage through the existing head gasket. (When I have done this before there was clear evidence of a breakdown of the gasket. However it has been several years.) Cylinder #3 (counting away from the distributor) was half full of water.
Question:
1) My neighbor told me I had to put the new head gasket on with (I think he said) "engine shellac" because it is an aluminum block and cylinder head. Is this true?
2) My nephew indicated that I cannot reuse the head bolts, I must buy new ones. Is this true?
3) Is it possible that the leakage could be from the cooling jacket on the intake manifold through the manifold gasket? There was evidence of leakage at this gasket (mostly just staining) but not at #3 cylinder.
4) I know that hot torquing the head bolts is not recommended but I believe that you are supposed to re-check the torque of the head bolts after some run-in time. Or perhaps they are supposed to be at 80% or 90% of final torque until some run-in time on the engine, after which they are supposed to be torqued to 100%. Is any of this true?

Your best bet is to send the head in and have it checked for cracks or warping. Hondas dont like to be overheated. Yes the intake gasket COULD be the source of your problem but it also may not be. It would have to be a serious leak on the intake. You do need to buy new head bolts when replacing. They are a one time use bolt and the torque may not be accurate if used again thus causing you to do it all over again. I personally have never used any type of sealant on head gaskets. I have used high tack lightly to help keep gasket in place while resetting the head. As far as the torque specs, I am not certain but most models require a set foot pound and then you have to go back thru again and turn an additonal 1/4 turn or more or even turned so many degrees extra. Hope that helped you in some way
