    Do the head bolts go into the water jacket on a 63, 327, 250 hp?

    It looks like I am leaking antifreeze at the first head bolt on the right side head. Does the head bolt go into the water jacket? It is a 1963, 327 cubic inch, 250 horse power, base engine? Thanks.

    Yes. All of them do.

      Remove the bolt, scrupulously clean the threads in the block and on the bolt, apply sealer to the bolt, re-install the bolt and torque to specs. Loctite Pipe Thread Sealer with Teflon is a good sealer to use for this application.

        It goes without saying, but I will: Drain the coolant first. Or at least lower the level some.

          Joe,

          Is this Loctite sealer a non-setting Teflon paste?

          Loaded question.

          I tried using a non-setting Teflon paste to seal head bolts once and it didn't work. From the amount of coolant I found under the valvecover, it must have looked like a Rain Bird under there with the engine running.

          I went back to tried and proven Permatex #2.

            We have used the Loctite PST or the Permatex equivalent with no problems for probably 40 years.

                Believe it or not put up many with nothing but motor oil on the threads and never had a leak. Ain't a gonna make Florida Joey, business comes firstest.

                  Good stuff......I have also used for MANY years without any issues. Used both at home and in the chemical plants in critical services. However, Permatex #2 is also a good and proven choice for this service.

                  But if Dick recommends it, you know it is good.

                    The choice of thread sealant will change the torque value that should be used for your head bolts. When using a paste with Teflon, one should use the torque value that is specified for molybdenum lube, and a dab of moly grease should be placed under the head bolts (and washers, if used) after applying sealant to the threads. If using shellac based sealant, like Permatex/Indian Head/etc., then you should oil the underside of the bolt head (and washer, if used), and use the torque setting specified for lubricating the bolts with motor oil. The moly value is always about 10% lower than the motor oil value.

                    I like the 12346004 - GM Teflon Pipe & Thread Sealant better than the Permatex stuff. It's much more expensive, but it takes much longer to skin over, and remains soft over time whereas the Permatex gets semi-hard and gums up the threads.

                      Many current GM SERVICE head bolts for Gen I and Gen II small blocks have what appears to be a teflon-based sealer pre-applied to the bolt threads

                        I've seen pre-applied white sealer (probably teflon) and pre-applied blue sealer (Loctite ?) on the bolts supplied with the last two non GM water pumps I installed. These were not for Corvettes.

                          Believe the GM sealer is packaged by Loctite/Permatex.

                            Doesn't matter who packages it. I've used both and they ain't the same stuff. They dry different, act different and even smell different.

                              back in the day i used a oil based torque spec on a main bearing stud when i used a moly based lube and snapped off the stud. lesson learned. just remember if you don't learn something new it is a day lost.
