Engine Build FAIL (1 Viewer)

[SouthMS40]

So I had the SBC for my FJ40 completely rebuilt and then did the worst thing one could do, I let it sit up due to an idle project mostly because of funding. We're not going to discuss for how long it has sat. I did spray a liberal amount of fogging oil in each cylinder and put a spark plug in each hole. I also taped over any and every hole in the block to keep anything from crawling in especially dirt dobbers. It has also sat covered inside the garage with no motor oil since the build.

Now that things are back on again what should I do to prevent destroying this engine on attempted startup? Do I need to pull the pan and bearing caps and re-lube the bearings? Or can I just use a distributer type oil primer and prime the engine and turn it over by hand several times prior to a real startup?

I would just prime it with a drill and roll it over by hand a few times to make sure everything is smooth. I pulled a running 350 and hung it on an engine stand. Shot some oil into the spark plug holes, replaced the plugs, threw a tarp over it and left it in my carport for 4 years til I had the $$$ to finish the swap. It fired up on the first go round and ran good for over 15 years. It had over 80,000 miles on it when I started, and probably over 200,000 when I finished. I sold it still running OK and passing smog, but getting tired. New owner dyno tested it at 127 wheel HP and pretty low compression #, so he is replacing it with a newer fuel injected 5.7. John

I did a similar deal. Pulled a good 350 from a truck I built and put it on a stand for "later". About the only thing I did different was to loosen all the rockers before storage to close all the valves...

I never had a need for the motor so I sold the it to a friend and helped him install it in his Cruiser. We used an old dissy and pre-oiled the motor. Rolled the motor over by hand until I had oil coming out of all the push rods. Then re-lashed the valves and fired it up. Still running fine to this day.

Pre-oil that motor and enjoy it!

I could think of many crummier conditions that motor could have gone through...I'm in the "prime with a rod down the dizzy hole and let er rip" crowd. After you add oil, that is

Thanks for the replies guys, you have eased my mind somewhat. After looking at all of your locations we have two in AZ and one in IN. I am located in extreme south Mississippi, 8 miles north of the Gulf of Mexico. My point being the difference in humidity. The average annual humidity in MS is 75% and can be as high as 95% during the summer months. Again I sprayed liberal amounts of fogging oil in the cylinder and taped over all of the holes. I guess at this point the only thing I can do is oil, prime, PRAY, and fire it up. I'll let you know how it goes considering this is the year!
