No Bondo, just the normal fogging.

Is it not just digging oil coming out ? That’s congealed in the exhaust ? Quite common on first start up on a trailer I’d say.

Thanks chaps, I found an old bike inner tube with a schrader valve attached. So I'm going to try the suggested jury rig and see if I can put 10lbs psi in and see if it holds. If it does then I guess its just fogging oil.
