I have an iron head 440 I built many years ago in my car now. I have exhaust manifold studs except for two holes which I installed header bolts (driver front bolt/passenger back bolt).
About 2 weeks ago I started getting a little drip from the passenger/back header bolt. fyi- I don't seem to have an exhaust leak. Anyway, I drained the coolant, removed the bolt, smeared it with RTV silicone....still leaked. I bought a longer bolt, cleaned/dried everything, squirted silicone inside the hole & smeared it on the bolt.....still leaking. I did verify that it's coming from that pass/back bolt area & NOT from the corner of the head (thank God).
Ok, before I do this for the 3rd time, does anyone have any good tips how to make sure it gets sealed this time? THANK YOU!
