Remove the rubber plug on the intake manifold where one would tap a boost gauge into.

Spray WD-40 for 4 seconds into this port. Crank engine and I guarantee you it will unflood and start right up.

It will also start an engine that's flooded with coolant too.

 

Never thought of that. Good idea, simpler than trying to remove plugs. I'd use a "real" oil, though. Perhaps a 2 stroke oil would be best. A cc or so would do the trick. Don't use very much, because it doesn't compress, and if you put enough in to fill a chamber...... Well, I guess "bang" is descriptive enough. ;-)

 

dude, try and make your subject lines a bit clearer than "Has anybody tried this? and does it work" maybe something like "WD40 To Help Start a Flooded Engine" would be nice...That way you can actually tell what the thread is about before you waste time looking at something you really aren't interested in.

 

I posted this a while back after my car sat at a paint shop for 2 months and flooded with coolant when I picked it up.

WD-40 is flammable and one characteristic of it is that it displaces water. The original purpose for WD-40 was to coat the Saturn rockets with WD-40 to prevent ice formation during fueling and launch. So spraying into the chamber would probably displace coolant.

Plus it's mostly in vapor form so it doesn't hydrolock your engine if you put too much into it.

 

Yeah, if you dumped in like an entire quart of oil...

 

I've used this nipple to force motor oil down the intake to start a car with a blown engine before...

Hence the name Water Displacement Formula #40

 

i've done this with starting fluid to crank a flooded engine. this was my last resort, as all of the other traditional unflooding methods were unsuccessful. it worked like a charm and the car started right up.
