I have a 1987 Honda Accord, five speed manual, and have 181k miles on it. It runs very good, never had problems, never been driven more than 15 miles( one way) commuter every day, but recently noticed that smoke and burning smell comes out of the hood, some of it is noticeable thru the cabin also. It occurs after about 5-10 minutes drive on the road and the smoke comes from the bottom part of the engine and rises up. No smoke thru muffler (tail pipe) at all, coolant is full and clear, engine temperature is perfect and constant within range. Is related to clutch?
Any advice with a quick fix that I can try at home is greatly appreciated.

 

Oil is leaking from somewhere and running onto hot engine exhaust to cause smoking. Possibilities are valve cover gasket, distributor seals, oil pan seal, or oil pressure switch.

Suggest cleaning engine to allow easier ID of leak location.

good luck

 

Yep, most likely.

check that oil filter is on tight
