89 C4 white smoke from exhaust

[Steve Fontaine]

hey guys, I am going to be finished paying off a C4 in a week and will be picking it up at the same time. It has been in a heated garage for 5 months during winter and when we started it up a bit of white smoke was coming out of the magnaflow exhaust. i even have a video so you can see. Its probably from sitting around for a long time but im not a mechanic. Thoughts?

What was the outside temperature? Just looks like exhaust to me.

 

[Malcolm]

Any sweet smell to it?

outdoors temp was +7 celcius if i remember. not cold enough for creating what your thinking.

lol i dont know. i didnt smell anything. im thinking oil change when i get it home?

I think it's ok. Watch your coolant level for awhile and see if it disappears any.

I agree with Malcolm , if you don't taste that sweet smell then she ain't burning antifreeze. And it would be really white smoke if it was. To me it looks bluish smoke, could be just a little oil down the valve guides and will clear up after a good warm up and run.

Agree with you Brian, I think it's nothing. Now a blown head gasket that's another story...

actually i was with the corvette last time it was running back in october. it was perfectly fine. which has me thinking same thing. just some condensation or something. it didnt smell out of the ordinary and i know what a usless head gasket does. this is definitly not a gasket issue which im glad about.

Wouldn't anti freeze show on the oil dipstick as a chocolate milky colour, if it was a head gasket?

 

[Malcolm]

Some times but not necessarily.

If there is coolant in with the oil there should be coolant on the inside of the oil cap. When it heats up it turns to steam and collects on the cap.

put some startron in the fuel tank. ethanol in gasoline will attract water especially when sitting.
