Thread: Flooded pistons no#3&4

A couple of weeks ago I finished installing a t25 kit on my friends B13. Last week, he was experiencing a couple of issues & his motor was leaking fuel. Since he had a spare highport, we decided to just swap it in & diagnose the problem with the old motor later.
We installed the "new" highport motor & were still having the same problem. We thought it was the cats, changed it, & we still have the same problem. We took the head off the motor & we spot that fuel is going straight through cylinder 3 & 4. Sparkplug 3 & 4 are also fouled.
What could it be thats causing the flooding?? Bad injectors?? Spanish witchcraft?? An ECU/ECM problem?? Let us know cause I am stumped.

The only fuel mod done to the vehicle is a Walbro #255 pump & ss lines.
The issues he was having with the car while it was running is that it had no power, was leaking fuel, & it was smoking, alot.

sounds like a stuck injector.

x2 thats what it woulds like to me also

leaking injector o-ring. put a pressure gage inline of the fuel filter to the rail. turn on the car and then shut it off. the gage should register a maintaned pressure for at least 15 minutes. if not...and drops to zero quickly. well then you know that there iss a bad o-ring...and needs to be changed.

Just as a pre-emptive measure, go ahead and reseat the injectors with new o-rings, anyway. It's best, for piece of mind, and doesn't really cost much at all.

Make sure you lubricate the o-rings with vasoline, so that you don't tear the brand new ones while re-installing the injectors.

x3 on the o-rings. That's your problem right there. Lube them with some Vaseline, and you'll be good to go.

OMG a CHRISCAR SIGHTING!

I say Spanish witchcraft!!!!!...nah check your injectors/orings most def...

I would just take the rail out and place it on top of of clean paper towels and apply fuel pressure to it (Don't start the car) and wait to see if it leaks. Like everybody here says it is probably the injector O-ring.

exactly.

ive made the same stupid mistake stinky.
