white smoke. funny idle

nordic97mist · 02-07-2012, 06:13 PM

My brother in law is about to buy the car from me. The car ran perfect. I havent turned in on in over a month since i compression tested it. Compression test came up perfect. I start the car today and the idle is pretty high, 2500 and there is quiet a bit of white smoke coming from the exhaust. I let it run a good 10 mins and it kept pouring smoke. I reset the ecu and the idle went back down to under 1k and the smoke stopped. I let it run a good 5 mins then revved it up and the idle went back to 2500 and started the white smoke again. I know white smoke is a sign of a busted head gasket but that doesnt make too much sense since its just been sitting. I checked the oil and it looks fine. Doesnt look milky and the coolant seems to be ok. Think its just condensation from just sitting so long that causing the white smoke? As far as the idle doing what its doing i really dont have any idea.

Smell the white smoke to see if it smells like coolant. I dont think that is the case though.-Shane

Broke

It doesnt smell like coolant. When it does do the white smoke thing the exhaust drips quiet a bit of water out. I checked the spark plugs just now and dont see any sort of green tint to them to suggest a head gasket...just really black from running rich

Valve?

nordic97mist · 02-07-2012, 06:44 PM

Wouldnt that have shown in the compression test?

1BAD4DR · 02-07-2012, 07:08 PM

you do the compression check before or after it started smoking?

Is it smoke or steam? Do a leak down test too.

Matts94Z28 · 02-07-2012, 07:15 PM

Remove drain plug, open oil fill cap, insert water hose, flush.

DOnt forget the bottle of NOS energy drink to help clean it.

ForceFed4g63 · 02-07-2012, 07:27 PM

Have you done a compression test since it started smoking? Check the TPS as well.

is pcm tuned for your setup?

neighbors brothers car did the same thing. Ended up being a slight crack in the head gasket. oil was leaking by also and getting the plugs a little wet and that was part of it.

After. It was prolly a good three weeks before i started the car when i did the compression test

Mustangscotty · 02-08-2012, 05:02 AM

Checked for codes?

Injector or two stuck open? Are all the electrical plugs in the engine bay secure and connections good? Fuses good? Smell the oil on the dipstick, does it have a strong smell of fuel? Vacuum lines leaking?
Is there excess discharge of water at the tail pipe?

My vote goes to a blown head gasket.

Smell the spark plug of your choice. What does it smell like after the engine has cooled down? Maybe cup your hand around the exhaust outlet and smell the condensation.

Air filter and pcv valve good? Is the filter wet?

If he doesn't want it with a blown head gasket, shoot me a PM with a price. I have someone very interested.

I dont know what motor you have. But I know with the B series motors ive had I did everything I could to blow a head gasket and couldnt.
