Rattle In Exhaust And Blowing Smoke

[Jonny P Star]

recently i got my 93 r32 gtst back from mechanics rebuilt turbo, 2nd hand engine (rb20det) and gearbox was installed.

on my way home my blow off valve seized open via a metal shaving got in there amazingly. so this overfueled the car pretty bad as i did not realize what was wrong until the car started to splutter and would not get passed 4grand then it stalled and wouldn't start again. the inside of the exhaust was black and so were the plugs. so i got a new blow off valve and plugs, but is still blowing smoke on acceeleration and deceleration and it tends to blow more smoke when it is warm.

i also have the cold start problem of engine shake and almost stalling.

now after a highway run to clean out the excess carbon its still smoking and now has a rattle in the "exhaust" like there is something in there, cant hear it from under bonnet, can hear it from under the skirt.

done bout 150-200km after replacing vavle and plugs and is stll blowing smoke but i didnt exactly run it hard on the highwat run.

any help would be great, jonno

failed o ring in rebuilt turbo, getting re-rebuilt for nothing as under warranty. jp

do a ecu diagnostic and get the fault codes if there is any.....

ur cold start problem could be ur IAC motor not working properly/seized or dirty.... located near ur throttle body ..... round cylinder with a plug on it..... pull it off, clean it....

and for ur smoke issue, once u get it bak with the rebuilt turbo.... get some "intake cleaner/head cleaner" spray from any auto shop, read the instructions on the can and it should clean out carbon build up......
