Title: other reasons for smoking?
Post by: ENVYD on June 15, 2008, 09:57:20 PM
well i got my engine built by lindop not that long ago. and when i got it back i stoped at the first service when i started the car back up there was smoke and they said it is normal on a new engine! how ever it still dose this and its run-in and mapped and so on.... so i thought it may be the turbos but was a bit odd how it never done this before hand! so could there be another reason?? and did anyone else who has had a rebuilt engine smoke for the first how ever miles?
 
thanks
steven

ive built quite a few now and they do smoke on first start up after a build due to the oil thats used during the build process but should not smoke after they have been run in. you do get a small puff on start up on some ported engines etc.....

If it is only on startup and dissapears after 20 to 30 seconds then that is fine.
