I told you guys a few weeks ago about when I was at a track and my car started smoking really bad during a 5th gear pull to redline. Well now I am seriously thinking of trading in my s2000 after this weekend. I was driving down the interstate yesterday and the road was completely clear as far as I could see. So I just stepped on it. I was running 70 and I just left it in 6th gear. About 130 or so I noticed it smoking a little bit. But I stayed on it, by 150 the car was smoking horribly. Well during normal driving and redline pulls through 4th gear it still doesnt smoke at all. I wanted to go forced induction early next year but I concerned that there may be something major internally wrong that will surface when I do that. I am defiantly not prepared to put a new engine in it right now, nor rebuild this one. I really need help on this one for possible internal problems.

Since that day it smoked at the track I have changed the oil and triple checked to make sure of a correct level, changed the pcv valve and the spark plugs.

I would do a compression test and leak down test before I decided on mods.

any ideas on internal problems that could cause that? Messed up Valve stem guides, blown rings, cracked headgasket? Its doesnt smoke any other time than on a hard top end pull. Then it smokes like my buddies eclipse does everytime just before its about it blow up,(but his always blows up and mine if i get off of it the problem just goes away) I just dont want to start modifying an engine thats already on its last leg? 80000 miles.

do a compression test and post the results, it hard to tell what it could be, i would think if you were getting oil blow by on the cylinders it would do it(smoke) at lower speeds as well. as the car ever been overheated, how many miles? any more info would help!

once again.

Compression test, and leakdown test.

during those runs you may very well be expanding already damaged rings as the motor gets slightly hotter and hotter letting more blow by through. this is a possibility, or cracked ringlands etc...

Were you the first owner of the car?

Of course I have been told I am full of it concerning my past comments regarding S2000 longevity but..

Revs make a difference and the S2000 turns 30% more than average since it is geared to be in the high power band.

IMO the life of this engine is gonna be in the 90K to 150K range and not the higher mileage that some have associated with some Hondas.

The car has 83000 miles

I am not the first owner, I am actually the third owner.

I will run a compression test tomorrow but I will have to wait another couple of days to have a leakdown test done.

I think that your logic about the 30% more revs dramatically decreasing the life of the engine may be right on.

smracer31

well its to be expected, im surprised the engine will last 75k miles as high as it revs, now for the 04 and up... maybe it will last 200k miles? lol

I've read a post on the atl website about a guy who supercharged his S at 100k and has had no problems even at 170k. I think honda knows what it is doing.

No doubt Honda did a good job, but there is no such thing as magic. Revs equal wear and more revs equal more wear and and a need for a rebuild.
