h smoke on start up

jsfarmall · May 27, 2015

My h fires up easily, runs flawless. If it shut it down and start back while engine is still warm I get a puff of blue smoke and lasts about half a second and totally "clean" exhaust. Is this an issue that will cause problems later of just valve guide seals that's not worth fooling with unless I'm tearing into the engine anyway?

Not a problem, that smoke is common.

Worn valve guides are allowing a bit of oil to seep into the combustion chamber. Most of these old Farmalls do it. It won't hurt a thing.

That's just verification the rocker arms are getting oil

Pretty common, there are no stock valve stem seals, oil runs down valves then burns on startup.

BTW, bugs me on mine too.

Yeah mine's done that the last 10 or 20 years or so.

10 4 thank y'all! Was concerned would cause a later problem or was an early warning sign. So if she quits smoking on start up add oil lol.
