Just taken my car 03 mondeo 1.8 petrol for its pre mot and the bloke says I am not going to be able to get it through the emissions due to it giving out a lot of blue smoke at about 3500rpm when you hold the throttle for a minute or 2.he says he has seen it before but isn't sure what causes it and in the past hes advised replacing the engine instead of spending time trying to solve it,seems a shame to scrap the car as it drives great and is still good on fuel etc

anyone know what causes it? and is there a quick/cheap fix?

it has done 125000 miles,hes says he has seen it happen at 70000 on other ones though

 

Duratorq is the Diesel engine. Anyway, have you noticed it loosing oil? It could be blocked breather pipes, worn piston rings, worn bores. Best to do a compression test and inspect the breather pipes. Could use a bore scope to inspect the bores. If the rings or bores are worn you're best of putting in a good second engine in or scrap it.

 

sorry,duratec i meant

doesnt seem to be using a great amount of oil really

 

Give it an oil change and pour in some Wynn's stop smoke. It might work.

 

hi mate,had the same thing on a 02 1.8 petrol...it was the egr just blanked it of and it was 100%[it only had 53000 mile on it,]cheers
