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. |

Clean the bores where the O-rings go thoroughly. Make sure they are smooth, with no casting lines or anything else to snag on.
I do not recommend any sealant that hardens. Like RTV. The tubes are supposed to slide in and out of the head; the wire retainers push them in toward the center of the engine but the outer end has to be able to slide in the bore. RTV as shown in Elliot's pic will eventually fail. I'm frankly surprised that it hasn't failed already... --DD |
