Past three days i have been workin on a 1980 S130 N/A slick top. Motor is runin strong, but smokin gray. I have changed the regulator. filter, ajusted idel. pluged vaccume lines. It can idle with no smoke. but when you hit the gas. it's like were sprayin for sqeter's. Tomarrow i am gona swap in another AFM, see if that helps. But i could use sugestions.

 

Hey buddy have you checked the oil level to see if it is going down? Might be burning some...just a thought.

 

Gray smoke = burning oil
Black smoke = burning too rich
White smoke = burning coolant

 

oil is good. burns none what's so ever. Coolant seems to be goin down. and it does smell a lil like coolant. just did not think of that as a suspect.

 

uh... since blue smoke is a sign of burning oil... it would prolly be burning oil if you see blue smoke.

 

it's more of a grayish white. he car burns no oil.

 

I had a car that blew a head gasket....it was the most beautiful, fluffy white cloud of smoke I have ever seen....then the engine locked up and I lost my brakes and power steering. My old dodge shadow burns 1 quart of oil a week and it is a strong running car (now my brothers) that smoke is a blueish grey color....I also would still suspect the oil.

 

The car came with an extra head. And the guy gave up on the car. Why he sold it. Btu since the car was not bought directly from the guy his self. the problem with the car was never passed on. I am gona let the car idle tomarrow. and watch the coolant level's. if they drop. then i might know why there was an extra head.

 

you runnin synthetic oil?

 

nope. striat up pensoil. And the levels have stayed the same for a good time now. It don't burn none. there's no blue color on the smoke

 

Ok ok, sounds like you are on top of the oil....do you see any wetness from the coolant around any part of the head? Freezplugs? Are you sparkplugs wet after it sits for a minute or two? Try to shine a light in the plug hole and see if you can see coolant or get some thin rope (shoestring, white and dry) stuff a length of it in each spark plug hole and check it for wetness.

 

cool. i will try tomarrow. thanks. And yeh. I am on top of the oil, the car sat for three year's. Then started up on the first turn of the key. Ran strong. Still is.
