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. |

I am sorry I don't remember the details, but it won't matter.
Buy both types of seals. The green ones fit perfectly on one end only. The black ones fit perfectly on the other end only. The remaining ones I toss in the trash so I won't use them ever. |

Regardless of whohever "FAT Performance" and "European Motor Works" are, (and since I've never heard of them they have no credibility with me (IMG:style_emoticons/default/confused24.gif) ) the best info on our cars comes from those who designed and built them. No sealant is specified to be used on push rod tube seals by the factory. (IMG:style_emoticons/default/beerchug.gif) |
