I've got oil coming out of my dump valve and was wondering how to stop it? someone has told me that it is the turbo seals that have gone and the turbo would need a refurb. is this the case?
haven't had a proper look over the car yet but might do tomorrow?
i'm not to up on the c20let engine at the mo as its new to me.
could it be anything else?
I have had both z20let and c20let engined cars, both of which had a small ammount of oil comeing out of the dump valve, I was told they breath oil a little.
I would say if its excessive or you have oil in the intercooler as said above it is probable that the turbo oil seals have gone and the turbo will need a rebuild.
Agree. My turbs is fine and it still spits a bit of oil out of the dv, If its really gushing out then you wanna worry but as everyone else said just keep and eye on it.
is nothing to do with the turbo dude its the oil vapours from the rocker cover, I tested mine several time its nothing to worry about untill you see blue flumes from the exhaust
u beat me to it, i too was gona say oil from the pvc system too... if that is the case theirs the mod for the rocker cover which is drilling holes into the plate and create a catch tank which is easy and u can find the info on maxboost
wot engine is it??? if its the z20let even if its been serviced at the right intervals the turbos will only last 40-50k. im havin the same trouble with my coupe, noticed oil comin from the dump valve, cleand it and the intercooler out then a week later it was the same and started to boost all over the place and have found the seals are gone!!!!
i've had my zafira gsi for nearly 3 years and its just under 90000miles with the standard turbo. my d/v has slight oil leak from it but i'd say it comes from the cam cover breather.
its true many zlet turbos fail but i'd say due to being utter thrashed than anything else.
