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. |

Not all 914's use the same seals. Early '70 1.7 uses smaller seals on the inboard or case end of the tube. 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) |

Porschetub:[/quote] do some research then you will know ,Porsche make cock-ups all the time ,time to listen to folks on here,good luck. [/quote] Porschetub, there is often very useful info on 914World, but there is also often misinformation and differing opinion. I won't be bulleyed into agreeing with you. In this case, I do disagree with those who say we should use RTV or other sealant on push rod tube seals. In my 40+ years of experience with 914's (beginning at a Porsche dealership where I worked and where I bought my 914 in 1976), I have learned a bit about our cars. I do not need to research your favorite shops and their methods, since I do all the maintenence and repair on my car myself, and drive it most every day. Back at ya, Porschetub- YOU should listen to those of us with true experience with these cars, and have a little more respect! Do you see any oil leaks from these push rod tubes? Not a matter of luck, just proper service (IMG:style_emoticons/default/beer.gif) |
