Need to know about an engine

I have a shortblock, rebuild with 4,000 miles, upgraded seals and a streetport. Now it sat outside jacked up in the car. I covered it with a tarp, but when I went out yesterday it was blown off and it was raining. Now the holes were stopped up with rags, but they were soaked. The outside of the shortblock has a bit of rust on it, and the pulleys are rusted. It the engine going to be ok? A shop said to look through the exhaust ports for rust on the rotors or anything, but what do you gusy think? Think any harm was done?

I think that shop was on with their advice. Get a flashlight and look at the internals. But I would never let it sit outside like that in the first place.

Did you put in some MMO or preservative oil and crank it before you pulled it from the car?

Dump a bunch of motor oil, atf, mmo, wd40, or something along those lines down into the intake ports while cranking it over. This will a) displace any water or moisture that has gotten inside and b) coat the internals to prevent rust in the future and keep the seals nice and free.

You should have no problems doing it this way, I do recommend that you crank it over a few turns every couple of weeks until it is put back into service.

Uh, guys I can't crank it over, the car is sitting outside because it has to. It is burned completely to the ground.

Fogging oil works well, also. Its nice because its in an aerosol can. You can spray it everywhere all over the block and the inside. Then turn by hand.

Oh, I just didn't understand what you were talking about. I have already done all of those things, and soaked it. But I still haven't got it out yet. I can't figure out how to get it out and I took the plate of the bottom of the tranny.

I did the same thing when I had a motor it outside. I just poured some oil into each intake manifold runner and slowly turned the motor over. It was fine.
