The motor was rebuilt 5000 miles ago. I did a oil change a week ago and put cheap spark plugs in the motor because i need an oil change right away and thats what I had at the time. So tonight a S2000 started reving on me because he had his wife in the car so naturally we go at it and of course he has that look of surprise as I start to pull car lenghts on him. After that my car started smoking and was sounding like a wrx. What could it be? I didnt over rev or misshift the car just started running like *** and smoke coming from the exhaust and entering the engine bay? Any ideas?

 

My guess would be a blown headgasket? maybe too much oil?

 

There could be several things that could have happened. you could have had detonation in th engine and caused damage to the pistons and /or have a spun bearing and causing a knock on the motor. Floated a valve and hit the piston resulting in bent valves.

Like stated before, it could possibly be a couple of different things--I know you said you didn't misshift or anything, but the symptoms you describe do sound like a possible (couple) bent valves......

 

I would check your cam timing first, maybe your belt jumped. How high were you reving because valve float is a possibility as well.

 

COmpression test it. My guess is bent valves or a piston rings gone. Happened to me along time ago in my old prelude. Sounded like a WRX too. Turns out i cracked a ring.

 

Could be a bunch of things, but not bent valves. Bent valves wont smoke.

Could be a cracked ringland, could be a spun bearing, could be your rings decided to fail, could be a headgasket leak, could be an oil seal somewhere...there are a bunch of things that can make your car misfire and blow smoke.

 

same thing happend to my buddy. one of the valves snap and it sound like a wrx r you sure that you dident put it in to the wrong gear by accident and dident know? or we you jsut pinned and it happend? let me know

 

the motor was rebuilt with dual valve springs, after market valves, new piston rings, new bearings and when I started it today no smoke. i was shifting at 7500

 

fresh headgasket also.

 

possibly a cracked header?

 

ohh im not sayin that your a bad driver or anything but no one is perfect. liek my buddy that snaped his valve he was racing this ricer integra and ****** he was playin bitch and he was bout to redline i 3rd and he went for forth and it ****** went in to 2nd. it was SO loud his motor probaly hit 9k and its just d15b7. which is a little sohc monster! hope you get it fixed or fine the problem. GL

 

checked header its good, I have a valvetrain like i said no misshift and I didnt over rev.

 

was the smoke blue black or white? did it smell sweet or like burning oil? and check your dipstick for coolant.

 

clogged cat maybe or a vaccum leak?

 

no coolant in oil, smoke was white and light, I have no cat and no vaccum leaks

 

Compression test your motor, i can almost garuntee that its a cracked ring in one of the cylinders.

 

could maybe have been water in your muffler if you wernt driving for very long. if its light white smoke then i wouldnt worry about it

 

he said it sounded like a wrx i dont think and h22 is supposed to sound like that.

I say it could be a blown hg. my friend had the same exact problem. good compression but sounded like a WRX. drove like crap. bad HG.
