It's been two days since I got my car back w/comptech sc...

I was just having fun driving the car and over reved entering the freeway (3--->2nd). Anyways, my car sounded okay so I decided to push the car again and same thing happened again while exiting the toll way...I over reved. I know it was a careless mistake...but I was sooo excited...

Well, now I think I'm hearing a clunking or a thumping sound when I depress the clutch at certain rpm during a shift...what can be causing this? I'm going to check my valve train just in case...but I have no clue about the noise coming from depressing the clutch...any ideas? Thanks.

 

First question...what RPM range did the overrevs happen. Were you at redline when you overreved?

Second question...do you still have your clutch delay valve in?

If you were at redline and you still have the CDV in then first guess would be that your clutch may have given itself up to save the rest of your engine. Any slipping of the clutch at high rpms?

You should still check the valve train especially if you did it twice
A leakdown test may also be in order. Better to spend a few hundred dollars now than a few thousand later.

Consider yourself lucky if the car checks out and if you still have your clutch delay valve in you might want to send a thank you note to honda engineers. They probably saved you a new engine.

 

Yes, it happened at redline and I still have the clutch delay valve.

It was weird...the car just stopped (similiar to when u hit the rev limiter) and the tires peeled as if I was braking hard for a second until I step on the clutch again...

By the way, it doesn't seem like my clutch is slipping though...it's just that noise at certain rpm.

I'm going to open my valve cover and check the valve train...but is compression test really necessary? My car idles fine and everything else seems okay...

 

Not weird at all. This is the sound of the rear tires locking up and driving your engine beyond redline.

 

ask yourself the following question. How much does it cost to run a compression and/or a leakdown test? Now ask how much will it cost to fix if I drop a valve.

Finding a problem early can save you alot of headaches later. It's up to you to decide how much piece of mind is worth.

 

Yea, what's the cost of a new engine these days - $8 - $9K? Pocket change it seems.....

 

all this over-rev talk is very scary to me, i ovreved my car once.i went from 3rd at 87 to 2nd ouch.this was like a month after i got my S,this is my first real sports car i ever had.but i think i just got lucky with mine because i had it for close to two years now and 5,500 miles later still no problems.but then again after i get my car out of the paint shop and put my gears and new clutch in thats when my engine will go boom.i know i dont drive my car much but its my weekind car so when i do drive it i drive it like i stole it.

 

Does anyone else see the fallacy of these two statements?
Hint 1: The car is most likely unfamiliar to you since it's your first "real" sportscar. No other car you've ever driven has the same sort of close gated 6 sp. manual transmission. Since you drive it so infrequently, you will take that much longer to figure out and get an instinctive feel for what the stick springs are there for and what they really do.
Hint 2: You drive it "like you stole it". This entails a certain amount of carelessness and "ham-fistedness" and a certain degree of "rough housing" of the car.
Hint 3: Put Hint 1 and Hint 2 together.

ps. History, as posted on this forum, would indicate that a few before you have made this very statement, only to discover that within weeks or months, the engine develops a peculiar valvetrain noise and odd operational characteristics. Further investigation has shown severe internal damage, which could have been avoided had a more precautionary approach had been taken. In any case, it's your nickel.

For both of the above replies: We make our own destinies, don't we?

 

I dont own an S2000 but the engine should be able to handle a bit of a thrashing right? They have a rev limiter dont they?

 

why are you coming down so hard on me i'm just sharing my own experience with this,alot of ppl have overeverd there engines especly since the trans is really close gatted like you said.i only did this one time a month after i bought my car,it was a mistake anybody could have made it.as for me being careless with my car i'm not.i bust a couple of 9k shifts when i run around town but who dosent and yes i may not have alot of seat time in the car but i can drive it real good i've never lost a street race in it.when i could afford to auto x it i did,so i would say normal every day driving time no but i do have a fair amount of racing time.oh and yes i know that i'm stupid for street racing so don't get on me about that.its a bad habbit that i know could get me killed one day but i cant help myself its fun sometimes.one more thing i would like to add is that i'm not rich nether are my parents so if my engine where to go boom and the warranty did not cover it i would have a 33,000 dollar sports car that dosent run siting in my garage and that just docent sound like any fun to me.

p.s i don't drive my car like i stole,i'm a spirited drive i like to have fun with it .
