Block Sealer question
I have one stud/nut on the head of my freshly rebuilt engine that has a very slight weep that hasn't yet gone away after a few retorque cycles. I've seen some folks on Forbarn recommend using some block sealer to fix this.
Is there a specific brand that I should use? Thanks |

Re: Block Sealer question
When this happened to me, I took drained the radiator down a bit, took the the offending stud out, coated the threads heavily with hi-temp gasket sealer, put it back in, and let it set up overnight. Then torqued the nut down, and it was good to go. No more "weaping".

It probably was on the cable clamp stud, they should outlaw those armored cable clamps!

Re: Block Sealer question
I believe that I once used blue silicone to stop such a leak. I wonder what such sealants due to the torque setting.

well shouldn't have any effect whatsoever on torque value....if done correctly. that is, the stud is seated/bottomed out ,by hand , properly..prior to any attempt at torqueing the NUT! the torque is the clamping force that the NUT is exerting on the head...not on the stud. |
