Expert`s comment:

The excessive smoke could be due to improper burning of fuel,excessive carbon deposit in silencer.Cleaning of silencer, checking of fuel supply system and ignition will help to solve the problem.Please contact service center for exact estimation for the same.

Answer by Shiva Shankar 03 March 2010

White smoke or black smoke? If the smoke is white, that could mean one of your oil gaskets or seals is broken and your engine is burning engine oil with the fuel. Could be a bit of a serious problem but nothing complicated for a mechanic. If the smoke is black, that is almost certainly improper combustion - easily taken care of. This is due to dirty injector or bad injection timing. Your fuel supply should be doing fine. Carbon deposit in the exhaust will not cause any smoke problem. It might cause some power reduction, but nothing more than that. Tough to estimate costs without knowing the problem. This needs a mechanic's estimate.

Better check your oil seal if it is white smock. Is it black ,no proper compression occurs in cylinder. Check compression using compression gauge. It might be the compression seal cracked. Also clean or change air filter.

Answer by Himanshu 07 July 2017

hi guys I am aso facing the same issue, hyundai 2006 accent crdi, while smoke and drastic fall in the pickup, i did fuel injector calibration , did not work, did carbon cleaning, did not my mechanic is telling its Head gasket to be replaced, which would cost you 40k plus, and that too its 2006 model, so getting its part is also highly doubt. So what is suggested me is to just get rid of the car in either exchange offer or in olx..if you get a desecnt offer of 80k, just push it off is what he said me, which i will b doing that and will post you guys how much did i get it in exchange once i get it...
