So my 83 has been sitting for a few months at the shop so I decided to drive it home yesterday and put it up for the winter. The car hasnt been driven for at least 3 months other then moving it around the lot and the shop. I drove it maybe 2 miles to the gas station to fill up last night and when I got there there was smoke/steam coming from under the carburator area. Smelled like burning coolant and there was a decent amount of it. Brought it back to the shop to check it out and there was only a little still coming out and I took a good look under the carb and from what I could see there was a little dampness but no puddles or anything. So the question is where would there be coolant leaking from under the carb/intake and do you think it just puddled out and pooled up while it was sitting and then just burnt off? I drove it home after checking it at the shop (15 miles mostly highway 80-90mph) and when I got home I didnt see any more steam and the smell was mostly gone. The car will be sitting for the rest of the winter now but I want to get a handle on this problem before it gets worse. Thanks for the help.

 

i could be your intake o-rings..

 

Yep, only place it could come from, particularly on the intake side of the engine.

 

Yippie skippy. Yeah, that job is waiting till spring. I guess it would be a good time to put on a header and get rid of the air pump and all that crap too huh?

 

How's your anti-freeze level look? That'll tell you how much you lost, which will give you an idea of how severe the leak is.

There's a small chance that there's a pinhole in the heater hose, that sprays AF on top the engine under pressure; it'd then run down & pool on top the mani under the carb.

Much more likely to be the o-rings, though.

 

you can replace them or do like me..and get freeze plugs..you can get them many places..i bought them at pineapple racing..Rotor Housing Coolant Passage Plug

 

This is only like a fifteen minute job, so don't dread it too much.
