Hey guys i have a 79 with a 350 in it it started smoking and i cant figure out where its coming from to save my life. It doesnt smoke right away it takes about 5 to 10 minutes because it smokes some its hard to see where its coming from but qhen i **** it off jt looks like it comes from under the motor ive replaced the vale gaskets and header ones cant find a leak anywhere it does have a trans leak somewhere could that be doing kt ? Smells like rubber burning though oil is fine and coolent is fine as wel so i do t think its a blown head. I have a video of it but dont know how to post it

 

first, welcome to the boards


now, what color is the smoke?


You mention its coming from under the motor, is it in front? to the rear? Do you have access to a jack and some jack stands? Maybe try jacking the car up, letting it run then shutting it off and sliding under there to see if something is dripping

 

could be trans fluid leaking on your exhaust too ,an if you just changed the cover gaskets could be old oil still burning off ,I had an 82 TA did it for a few days after the change,
