Blowing Smoke out the exhaust, help
 

hi all

ive recently carried out an LS1 conversion on a MK2 Ford Escort here in Scotland, the car is now finished and road legal, been driving it over the past few days and have noticed that when i boot it i get a massive could of whitish smoke but then it goes away when i return to normal cruising and if i boot it again and again everything is still fine ???? also happened when i was in the garage when started from cold i revved it and got a massive cloud of whitish smoke (not black) but smelt like burnt oil, im a little concerned has anyone got any ideas or suggestions on what it might be ??

could it be over fueling when i floor it ? or worn internals, air leak etc etc ? it only happens once in a while not all the time

oh should mention that engine has sat for well over a year dormant

any help is much appriciated

Start up and after you floor it sounds like valve seals. Extremely unburnt raw fuel can appear to look like burning oil but it has a white screen too it, but you would smell it. If it smells like oil, it probably is.

Mine did the same thing, a puff of white smoke when you fire it up and a puff of smoke as soon as you smack it to the floor. I thought it was valve seals but ended up being rings!

Thanks for info guys, might do a comp leak cheak on cylinders, it pulls clean like a train so no too fussed at the minute

Cheers

Nice looking ride, enjoy.

been investigating this further

removed all inlet breathers from crank case and valve cover to check for oil, all clean but when i removed the intet filter ther was some oil just sitting in the TB, found this strange ! could this be comming back through the valve seals somehow ?

cheers

did you rebuild the whole enging or just replace the rings ?

cheers

It was the rings. They were fried from years of nitrous. Just checked one of them. But I haven't messed with that short block bc I swapped it for a 4.8 when I was building my turbo setup
