Vacuum plugging

[Scott Nutter]

Thanks for the responses. Has anyone use that quick steel epoxy putty to fill the vacuum lines? I would just like a more permenant solution, I did toast a motor once due to a vacuum leak and I still don't check them often enough.

If you want the most permanent solution you need to braze them closed. Epoxys can work loose over time. I'd trust the silicone caps over an epoxy.

Plus I'd hate to see what a loose piece of hard epoxy would do to a tip seal or a piston ring.
