I just read on a non-S2000 forum about a guy who uses common steps to clear a flooded engine (i.e. turning engine over while holding accelerator to the floor) as a way to slowly lubricate an engine after being unused for an extended period of time. I did a little research on this forum and it seems that our S2000s might have ECUs that disable the fuel injectors if the engine is cranked under full throttle. My S2000 sits unused for extended periods of time, so finding a simple method to minimize wear at start-up would be great for me. On the other hand, I have never heard of someone doing this before, so I am a little skeptical. Do any of you all have opinions on this?

 

I have heard about putting a tiny bit of oil through the spark plug holes. Although I can't confirm that it works

Urban legend, no need to hold the pedal to the floor with (full throttle & cold start could be a disaster all your oil is in the pan). no carburetor to flood. storage is no problem for this car unless it's for more than a yr. Just keep the battery charged. Others will chime in.

 

I can't give you a link to some study, but I recall reading synthetics tend to leave a better "film" than dino oils. Also use a 0W-30.

 

Assuming your anti drain back valve is working, would cranking the engine over by hand help or is it just better to rip the bandaid off aka cold start?

 

I don't know about the pcm cutting fuel flow at WOT at start-up ? , I don't know if that is true or not.

I will disable the fuel pump and coils, and I will turn the engine over 2-3 times to get oil flowing through the system while the engine isn't under load. Sometimes I'll remove the plugs to make it easier to turn over. But my engine sits for 5 months without being started during the winter season. If my car was sitting for 2 months or less I probably wouldn't go through the effort. I never spray any fluid into the spark plug holes, I'm always concerned that I will mess up the spark plug tubes.

 

well in my experience at the track whenever i spin off of run off and the car stalls i cannot get it to start unless i hold the pedal to the floor. if not you can sit there and crank for a couple minutes and it won't start, fully depress the gas pedal and crank for 5 seconds and she starts right up. Maybe a different scenario though..

 

I don't know if wot flood clear works on the factory S2000, but I do know there are a lot of cars that have that feature. I can also tell you that the AEM ECUs have that tuned into the base map for the s2000.

 

If you want to be really anal (like me), you could install a prelube pump. All I do is flip a switch under my dash and oil gets pumped from my drain plug port into my oil filter. Since the oil pressure port is located after the oil filter, I just wait a few seconds to get oil pressure, and I start the car.

Another option would be something like an AMS-Oiler. There are other variations on this as well.

 

For cars that have been sitting/unstarted for 6+ mos,I have done this:

Take the plugs out,spray about 10 sec worth of WD40 in the holes,put new plugs in and let sit for a day.Also,to be on the safe side,change the oil & filter.Use 1/2 of your fav oil and half MMO( Marvel Mystery Oil) and fill the filter with oil.

If it starts,just let it idle for 5-10 min.Hopefully the gas is fresh enough not to cause a problem.

Just a suggestion.
