Well after my accident a month n a half ago I got it back on the road a week ago. I primed the front end because I got tired of the red bumper, black/burgundy fender, and dark gray hood. Eh looks better imo... dont hate cuz I dont care too much lol. And its dirty...so what lol

I have tons more pictures, but these were my favs. Taken with a sony alpha 300. First two images were slightly modified. Just upped the saturation.



I'm having idle problems tho. It idles fine but feels a little rough. And when I quickly push and release the accelerator, I get white smoke. A slight loss of power too. Vacuum leak maybe, or HG on the way out...im not sure.

drain your oil and see what it looks like. do a leak down test. if it were a headgasket it would be white all the time. its probably just oil smoke. worn rings would be my guess....

I'm thinking the HG, oil wouldn't make white smoke.

yes, but if it were the headgasket it would be puffing out white smoke like a coal train puffs out smoke. the OP doesnt know whats wrong with it and its his car.... its probably blue smoke (which sometimes people will call white). most people just know black, and white. they cant really tell the difference between blue smoke, and white smoke but i sure as hell can lol.

If the smoke isnt from coolant, and its from oil it doesnt always mean rings. And you said it happens after you hit the gas. Good just be a bad PCV valve. They are ment to release crank crase pressure back in to the intake manni, but after they go bad they will let oil get in too.

Its def white smoke. I know blue smoke, i helped change a friends turbo which was spitting oil.

link here for the blown turbo. http://www.youtube.com/watch?v=nXqaPfGzOEc

I'm going to try to take out the front timing guide and see if its just off timing, but i know white smoke comes from burning coolant. eh... i was gonna do a 5 spd swap too, but if the engine is on its way out, whats the point/

didnt do much today...just did a compresssion test. I got 160-165 across each cylinder. How much do shops usually charge for a leak down test?

Figuring the compression is good, the HG/piston rings being blown is out of the picture. I have a few things it may be.

1. Bad injector2. PCV 3. Timing4. Running rich for some reason

I disconnected the EGR and plugged the hole where it goes into the intake...could that be a problem?

timing would be black smoke btw.... bad injector wouldnt cause white smoke....running rich would cause black smoke.... and i highly doubt its the pcv valve causing it to smoke like that. have you drained your oil??? what does the smoke smell like?

disconnecting the egr wont cause a problem as your describing. take it to someone who knows what theyre doing is my best advice.

I agree, this is not a fuel issue. Have you looked at the coolant in your radiator, nightsauce?

Sounds like bad valve stem seals to me. Both of my sohc's started that BS after 180K.

I solved that by RB20 swapping. If I hadn't you can just replace the stem seals and it'll be fine. I didn't read much about it but I guess you can pressurize the combustion chamber when its at TDC and replace the guides then. Or I think that's about how it goes.

guys, the OP says its WHITE smoke, and NOT BLUE smoke. he says he knows the difference between white and blue. valve stem seals would be blue smoke. i honestly dont think the OP knows enough to diagnose, and fix this on his own. hence why were here, but i honestly dont feel like your giving a good enough description. as i asked before, have you drained your oil??? check the coolant too. those will tell everything.

like i said before, take it to someone who knows their KAs....

coolant wasnt dark / oil wasnt milky.

thanks to those who gave their input :]
