I am afraid of using too much Marvel Mystery oil. Car has not ran in over 7 years, but no reason to expect copious amounts of surface rust in cylinders.

I don't want to glaze my new plugs, royal pain in ass x12...
If the engine's not stuck, then you don't want MMO. Engine oil is what you want between rings and bore. One light shot down each spark plug hole, then turn the engine through a rev or two.

If you're planning on starting it afterward, just disconnect the ignition, leave the plugs out, drape a heavy towel over the plug holes, and spin the engine with the starter (after turning it over by hand first) for 10 sec or so. That'll blow any excess oil out of the cylinders through the plug holes. Put things together, and start it. I've never fouled a plug on an engine after doing this. You'll get a little puff of white smoke on startup, but there's never enough oil left to keep things from working.

pre oiling

ehh

sure if it is an expensive Maserati engine. But sitting with dead old oil either has or hasn't rotted the bearing shells. You cannot know without taking it apart. IF you are going to take it apart, why are you starting it?

If it isn't full of water then you are not that different from starting it from an oil change, and if you have those serious doubts, you shouldn't be starting it.

Change the oil, check the coolant to make sure its coolant not dust.

Starting a long dead car is basically a small piece of disrespect. You are betting it doesn't throw a rod in the first 10 seconds, but kind of don't care if it does.

That Elise in that guys yard in florida for 10 years, hell ya, I'm checking the oil and throwing the jump pack on it. Toyota motors are a dime a dozen.

Even Lotus twin cam, cheap lower end go for it.

That Turbo Esprit or Maserati Merak, matching numbers 63 Vette, yeah, think we are towing her home and taking the long way.

Mystery oil is a great penetrant, so absolutely squirt it down the bores, then wait and follow with oil.


As a side note, the money he is talking about for a twin cam rebuild is crazy town, hell a new Ford block is less than 2 grand on your doorstep.
