Basic info: 1938 Chevy Master Deluxe inline-six 68K miles Stored in a garage all its life Never been driven in wintertime by original owner Engine was rebuilt and all electric components replaced in 2001 after a piston developed a hole. About six months later, Dad tried to start it but something happened, and the mechanic said that the pushrods were bending due to bad gas deposits making the rods & valves stick. Took the head off and boiled it, I think. Fuel tank was emptied and cleaned out. Put it back together and all was fine. Shortly afterwards, Dad could no longer operate the clutch, so the engine has not run since. He added oil in each spark plug hole twice a year. Sat in the garage since for almost 11 years now with the same gasoline and all other fluids. Car is now in my possession, and I am pretty sure that I will have to clean the bad gas deposits as well. I don't want to try cranking the engine until I am sure nothing is going to bind. 1) If I remove the spark plugs, put a little bit of oil in each cylinder, remove the crank hole cover and use a ratchet to hand crank the engine, will that be a good idea to get the moving parts lubricated, or should I assume that I have to remove the head and have it professionally cleaned? 2) If there are sticky gas deposits, I assume that the only way to tell is to see if there is a lot of resistance while trying to crank the engine without compression? 3) If there are deposits, is there any less intrusive way of cleaning them without removing the entire head? Everything under the hood looks brand-new from the factory, so would like to keep it that way. Thanks for any tips or suggestions. p.s. If anyone here has experience with these old Chevys, especially with knee-action shocks, let me know, I could use some expertise when I eventually restore it. If there is enough interest, I can post pics in the shiny-things section when I get the chance.
