Mikey,

it would be pretty funny to show your S2000 on a track with some oil coming out the back... honda would say... NO SOUP FOR YOU!

I personally don't see it as an issue about a little bit of oil burning after being splashed all over the place.

Those turns at Summit Point aren't unique, you could probably reproduce it on the street. Might have to drive with a bit of emotion though. My understanding is that on-track driving school's don't invalidate the warranty.


BTW, what kind of oil do you use?

 

I've noted that my spark plug no.1 or is it no.4, whichever is closest to the front of the car has some oil on the threads, while electrodes are perfect dry. Do you have the same condition? Make sure you drive hard before the check.

 

The same thing that happens to S2000 drivers that don't account for the car's understeer - they get to meet the tire wall/sand pit.
Never happened to me though, the 930 has an undeserved reputation for bad handling though it does take a skilled driver to extract 100% of the car's potential. The record of 911/930/934/935 victories on the track for the past 35 years is offered as proof.
By the way, I feel that the S2000 is as close to a 1972-73 911S as it gets. Peaky power at high revs, light weight, moderate understeer followed by snap oversteer at the limits, great mechanical sounds, good looks, low production numbers, etc. Both are phenomenal cars.

 

Oct 29th I had a full day of track time at Gingerman. No blue smoke at all from my car.
Yesterday I had another day at the same track.
Only change was new oil change.
I use Mobile 1 5/30 before and after. I had 3k miles on the first oil before the change.
Yesterday I had huge buffs of smoke. Enough that I couldn't see Greg behind me.

The smoke only appeared after three tight high speed twisties and some heavy braking. But it went away in the afternoon.
I too think that it was possibly an overfill problem.
Hopefully something here can help.

Hi everybody! I would just like to share few thoughts about the smoke thing. When I was running on break-in oil my manifold as well as the pipe from filter to TB used to get oily and I have never taken the car above 5000 rpm. When I changed oil I cleaned up everuthing and it seems to have stayed dry ever since. I used MOTUL 300V synthetic oil but with a viscocity of 15W-50. 5-30s , 10-30s even 10-40s are oils made for energy conservation for every day driving and according to my and my dealers opinion they cannot offer enough protection at extreme operating conditions. Also ask guys with a B16 V-tec engine and they will tell you that when it was introduced HONDA specified 15W-50 oil. Next generation V-tec they redesigned the bearings in order for the engines to be able to use 10-40 or 10-30 oils wich help lower consumption of the vehicle . Also most synthetics in the market use viscocity modifiers to achieve the specific viscocity. The MOTUL 300V is ester base stock build to the specific viscocity thus there is no modifier additive which could break and lead to viscocity breakdown. The oil is developed in conjuction with race teams (MUGEN included) and it has minimal evaporation at high temp. It can even handle racing fuels. Anyway it's worth the money and the time you should spent to find it in US. If you insist on using 5-30 or 5-40 you can have it in those too. If you don't trust my word ask any guy who rides superbikes and he will brobably tell you the same about 300V. My intake is dry now guys.

[B]The smoke is from the crankcase ventilation as mentioned above.

 

I used to race Dodge Neons (DOHC coupes) and we had a similar problem. Blue smoke (oil) on some curves that generated high g-loads and hard braking.

The fix was a little jet (like a nitrous jet) place on one of the crankcase ventilation system hoses. Mopar Performance issued the solution and sells the part.

 

now would a dry sump system fix that problem? i keep hearing car magazine talk about it, but i have no idea what the difference is and why it's so much more expensive.

 

Porsches have dry sump systems. The oil is pumped to the engine via a separate reservoir that is filled from the oil from the oil pan. If the oil pan is "starved" of oil due to g forces and the like, the sump will still have enough oil to keep the engine supplied and oil pressure up. The '86 Turbo took something like 8-10 qts of oil (memory vague on this).
