Hi guys,
My S2000 has been stood a couple of years.
I want to safely revive her from her sleep.
The engine is free, I checked by pushing the car in gear.

Would you put something in the petrol, like RedEx or similar.?
The tank smells fine.
Should I empty the tank? Where would you disconnect the fuel line to pump it out with the fuel pump.?

thks

remove fuel pump fuse. open valve cover and drizzle oil over the moving parts- cam, rollers, etc. perhaps remove spark plugs and spray in some fogging oil- let it sit. manually roll the engine over to lubricate. Might as well check your valve clearances while you're in there.

button it up. run a clutch interlock bypass so you can turn the engine over without putting pressure on the thrust bearing when you push the clutch in. Remember, your fuel fuse is still out, so turn the engine over until the oil pressure light goes out.

Put the fuel pump fuse back in. Depending on how much fuel you have in the tank, put some high test in to fill it up.

Start the car and let it idle. Drive it gently till the old fuel is used up.

I left a car ('88 GTX) sit for 5-6 years with old 94 octane in the tank as I was replacing the engine- the replacement engine had sat for 10 years indoors. Followed the above procedures and gently used up the old fuel- car ran fine.
good luck.

Excellent advice. I'd also add a very good fuel injector cleaner. Fuel turns to varnish, and loves to clog small passages.

The Chevron Techron product is very good at this. There are two versions. You want the fuel system cleaner, which is much more highly concentrated, vs the lesser fuel injector cleaner.

Hopefully the fuel tank was left full, so it didn't rust inside. The sooner you can add fresh fuel into the mix the better. Dilute the old stuff. So top up once you drive a little and there is room to add some.

 

I also pour half of a quart of any new oil into the oil port on the valve cover. I do this to put some oil onto the dry valve train parts, so that there is some oil on them when you bump the engine.

Regardless of whether you do this or not --- you should change the oil after the first start-up. Drain all the old stuff out and change the oil filter. You also may want to open the air cleaner housing and see if any critters or buggies decided to make it their new home.

Good luck, with the restoration!
