Our otherwise great Onan erupted into a cloud of smoke at the fireworks. I shut it down promptly.
The dipstick has gotten so loose in the tube that not only does it not seal, but the crankcase pressure will easily blow by it.
I wrapped it with teflon tape and put it back on-line as it was a hot night. This worked, but I know it won't last long.
The seal does not look replaceable. JimK might have new, but the shipping would have to exceed the part cost.

Does anybody have a plan to make the dipstick stay tight?
