Need a little wisdom. I installed one of Chris's exhaust systems ( It works beyond a expectations!!!! ) and pulled the push-rod tubes so I could install new Viton O-Rings.
Now, I have two tubes that leak. I watched my trusty Raby Type IV rebuild DVD and first time, straight motor oil. The second time I tried a dab of grease. Both to no avail. These leaks are tiny; just a drop every 3-5 minutes... but one of them is dripping onto the header! Are there any secrets ? mystery goo / sealers to use. Any and all advice is greatly appreciated. |

High temp RTV. Works great. Just be careful to clean it up good. FAT Perfromance uses it and if it's good enough for FAT, etc. etc.

As the Cap'n rolls in his grave. [/quote] (IMG:style_emoticons/default/agree.gif) I was wondering when someone would mention that RTV and other such sealants are a very bad idea for use on push rod tube seals, since the parts need to move as things heat up and cool down...that expansion and contraction stuff. I am surprised that so many folks are so quick to offer such poor advice... (IMG:style_emoticons/default/confused24.gif) wish that the Cap'n were here to offer proper admonishment. With the correct seals for the engine, properly installed....the push rod tubes do not leak. No sealant or RTV or other such goop is needed or desirable. |
