Sticking inlet valves
Hi to all !
I just restored a 1961 Galaxie with a 292 Y-Block ...the engine was sitting some years in a barn but itr was not a problem to get it turned. Now I started it , but realized some troubles - 4 inlet valves sticked . Has anybody an idea what to do now, I dont want to remove the heads....is there a way to get them cleaned and free moveable without removing of heads ??? Thanks, Andy

You should probably just go ahead and pull those heads. In my opinion if the valves are sticking they are more than likely coated with rust and will give you trouble down the road. It will tear up the seals and start burning oil and the rust will tear up you valve guides. It will probably cost you less in the long run to do the work now.

Pop the valve covers and squirt some penetrating oil on the valve stems let sit over night then use a soft faced hammer and tap the valves down with a sharp quick blow. they'll pop up. Repeat a few times with oil and blows then start it up and let it warm up.

I have seen this on a number of occasions, and all were due to the burning of old fuel. If you fired it up with what ever fuel was in the tank, and it is old it will cause the intake valves to stick due to the varnished gas.
Once you get the valves moving again, you better check the pushrods to see if they are bent.

Marvels mystery oil may help, also some fresh gass with a good fuel aditive to strip the gunk out of the system.

I replace my marine fuel line evry year due to sitting.. It's just good practice.. Fuel sitting is a bad thing for any type of motor..If it's the cause for your trouble consider the carbs, line(any elbows/links that are rubber), pump, filter....clean it all up or...you get the idea..
