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

kaoss_11

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

kaoss_11

fresh headgasket also.

possibly a cracked header?

JDMbitches

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.

kaoss_11

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

K.H22hatch

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

C1CRX

clogged cat maybe or a vaccum leak?

kaoss_11

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.

K.H22hatch

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

JDMbitches

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