Can somone tell me the reason FC's flood.


Im interested in buying one, and I would like to know what parts I need to replace to make it stop flooding...





Also, after long periods of flooding, why do the seals need to be replaced? Could you do an atf treatment and revive the engine?


Thanks alot I appriciate it!

well, i only had a flood once on my S5. What i think happend was they i didnt drive it for so long, the oil required to make a seal on apex seals drained off over time. And when i went to start it, it could not make any compression and flooded. Or i have leaky injectors...

leakey injectors is the most cause of flooding. try getting a fuel cut switch

Just make sure the injectors get serviced (cleaned/replaced). The fuel cut switch is a band-aid fix from what I hear.

Ive only had my car flood one me once, once was when i started her up, and moved to a differnt parking space after she was cold, then tryed to start her like 20 minutes after that. Unless you have leaky injectors they only flood if you move them a short distance while cold, because the ecu injects alot of fuel when the car is cold and will flood the motor sometimes when this happens. I think that problem is fixed on s5's though.

can anyone confirm that they this problem was fixed on s5s?

They didn't entirely fix the flooding problem on the S5s. They added a fuel cut whenever the throttle is wide open while starting, something the S4 didn't have.

Flooding is caused on both series, by the same things.

Either leaky injectors or low compression and in a few very very rare cases a problem in the ECU. On older motors, where compression is a little low, it can also happen if the engine is not warmed completely before shutting off.

And as mentioned above a fuel cut switch is a band aid at best, and should not in anyway be considered a long term solution.

And anytime the engine is flooded, you must change the oil ASAP. Not changing the oil will result in reduced compression from diluted oil failing to lubricate as it should.
