Hi Guys,
I have new pushrod tubes and viton o-rings ready to install as my quest to keep kitty litter out of my garage continues... The bores are super clean and look like they'd make a good seal...but when I serviced the tubes last year, they did leak a bit. That was using new viton, but the old tubes. The new tubes definitely seem to "seat" the rubber better. What are your thoughts about using yamabond (or some other flexible sealant)? Is there any downside? I assume it would only go around the seals on the case side, right? Thanks! |

Rotated the tubes 180 degrees (surprisingly easy -- little torque?), some improvement but still three to four drops from the passenger side pushrod/cylinder area while idling the engine for about 15 minutes while checking timing etc. Looks like I am going to have to reseal the cylinders to the case, (IMG:style_emoticons/default/mad.gif) Plan on using Yamabond for both the cylinders and the tubes.
