Firing up sefi engine that's sat for a few years

Postby bsaunder » Tue Nov 04, 2014 3:43 pm

I'm slowly resurrecting my Bronco from a six year sleep - next item is preparing my engine to fire.
I've already pulled the plugs and put some marvel mystery oil in the cylinders. I'm planning on draining the oil and then refilling with new, putting at least a quart in through the pcv breather to try and get most of the upper. I'll pull the dizzy and work the oil pump with a drill, re-stab dizzy, hand crank, and prime again. Also planning on making sure all the fuel lines are drained and then run the fuel pumps for a while (fuel pumps only, no crank) and change fuel filters.
Water is in good shape as well are hoses, serpentine belt, etc. The engine (351w, sefi from 93 Mustang, roller cam and rockers..) is still practically new and barely broken in yet.

Anything else to check before I try and fire it?

Dead, dead, dead, not even 2 volts across the terminals so I'm not sure I want to try and charge. It's a procomp knock off of an optima.

getting a new one is on the list

If it hasn't cranked over in six years I think I'd turn it over by hand a couple of times.

Swipe out the cylinders for cobwebs?? LOL! Seems like you have your bases covered to me. Lubrication is the key. If you have that covered it's unlikely you'll damage the engine.

lol - I was actually thinking about that for the intake and exhaust, but figured a little roasted silk would be ok. :D

I did make sure nothing crawled up and nested in the exhaust though. My dad had a bunch of field mice make a home in the muffler of his hay truck one year; doubt I'll ever forget that.

I bet you'll be fine with a little oil in the spark plug holes and doing just what you said.


BTW im glad to hear you are getting it back up n running.
