The above rod broke as a result of 3/4 quart over fill. This I meticulously measured. It didn't even happen on the track, it happened during a mild corner at the Dragon.

Piston top and spark plug were soaked with oil, this was 100% oil hydrolock. The large intake of oil at one time was more than that of the combustion chamber size. When I looked into the cylinder with a penlight, the piston top had a pool of oil on top of it.

The guy added a quart of oil when we arrived at the dragon after our 850 mile highway drive, ASSUMING he would be low after the 850 mile drive down. He did not check it. He didn't realize all those highway miles consumed no oil at all.


Fill the oil to the TOP OF THE TOP DIAMOND, and that is IT! Not covering the H.

You are 10x better to have the oil at the bottom of the safe range than over fill.

You may be surprised, but I am not surprised at all.

Billman, do you think I might be have caused some damage so far?

I want to have your opinion about what test I should do in order to make sure that car is in fact running perfect? ( I was considering leak-down and compression.)

Also, what is the proper amount of engine should be put in this engine?

Thanks for your time Billman.

I doubt you have done any damage..but you were close.

Exact amount of oil is as follows, and how it should be checked:

With the car ice cold in the morning, after sitting overnight, on level ground, you want the oil level at the top of the XXXXX. NO more.

And MOST IMPORTANT!!!! The s2k is one of the only cars in the world I know that pick up a false layer of oil from a gap between the windage tray and the block. It coats ONE SIDE of the stick, giving a false reading. If one side shows perfect, and the other side shows nothing, you have NOTHING in the engine.

BOTH SIDES of the stick must match.

Thanks Billman... I think this is an important issue, once I get the car fully checked on Thursday... I will post the results and inform anyone who reads this as much as possible.

The lower side is always the correct reading.

A reputable mechanic which works on lots of s2000s told me that : It is somewhat common to see this happen in s2000, and he though it was b/c of head gaskets around the spark-plugs
I assure you 100% that the tube seals (what you called head gaskets around spark plugs) have nothing to do with what is happening with your car.
What do you think is happening here Billman? In this video here it looks like he's shooting smoke under hard braking rather than cornering.

He also mentioned he overfilled his oil.

Maybe that video is a delayed reaction? There is a corner right before where he starts to smoke?

:edit: nvm...idk hah.

While at track events I have noticed numerous S2000's smoke under very high vacuum conditions, and based upon the sound it was drivers that didn't match revs and downshifted early. Of course this happens at approach or even though lower speed turns. Only my observations, but in more advanced groups it seemed well timed rev management had much reduced smoking.

Sorry for not getting this.. you say top of the diamond but then say top of the Xs... so their so may ways to look at it, makes it confusing.. i think we should start calling them chevrons that way its broken down individually. Xs L|< XXXX>|H .... Diamonds L|<><><><><>|H.. they both can be viewed as x or diamonds .. but going by XS you will be one Chevrons less then with diamonds which would put you right under the H...

so which is it ?

I know not to go over the H. I understood that part
