1997 Honda Accord V6 Sedan Automatic

Bought car, wasn't smoking.
Changed oil and filter with QS 5w-20
Wasn't smoking

Put new distributor cap on it
Wasn't smoking

Drove about 100 miles.
Error code 80

Cleaned EGR passage (it was nasty)
Wasn't smoking

Used engine degreaser carefully
Wasn't smoking

Pressure tested the a/c system, then added the 3 in 1 (oil/sealer/freon) 18 oz bottle of that EZ Chill stuff to the a/c
While car was running and adding the stuff in, it started smoking white out of the exhaust....

No check engine light on, no irregular motor noise, no water in oil, not running hot...

Ideas?

 

Let it run a bit and see if the smoke continues.

Smell it to see if its burning coolant or not first.

 

Forgot to add that it smoked real bad when I put the a/c stuff in... Then it quit... It comes back slightly sometimes, but not real bad.
When it first started, it was like I was killing mosquitoes lol

 

The real strange thing is the there shouldn't be any connection between adding stuff to the AC system, from there to the exhaust...???

 

I know, nothing about the two mix.. Very very strange indeed.. That is why I'm baffled lol

 

What pressures were you reading on the a/c system to prompt adding 18 oz of R-134a?

If you unplug the connector to the a/c compressor, do you still get white smoke from the exhaust.

 

0 -- Put a vacuum on it and it held at 20, so added in to about +35
Will check the plug and test.

 

Only thing I could think of is when the engine increases load because of the AC its causing stress somewhere, maybe the headgasket, and coolant runs through. But the ac shouldn't put that much strain on the engine, anymore than driving around would.

Try getting smoke to come out of the exhaust by other means. High revs, high load.

 

did it by any chance overheat while you were fiddling with the ac and it was idling and you didnt notice ? compression test to find out

 

Engine didn't overheat or even get close to overheating while filling with ez chill. I was sitting in the car with the max a/c on seeing if it got colder while my stepfather added the ez chill.

He got down there and smelled the exhaust and said it didn't smell like coolant or oil, (he's a mechanic for many years) -- but he's completely baffled as well
