I just bought a Fez turbo for the missus, it needs a little work and possible a turbo overall but it generally ok . Its had a rebulid recently, about 20 miles ago to be precise however it keeps blowing the oil cap off. Does anyone have any ideas, obviously its pressurising somewhere but are there any key areas to look at first before i start pulling it apart.

Thanks all

 

check thr breather on end of rocker cover isn't caked up.....if its not then it prob requires uprated breather.

Thats the optimistic way of lookijng at it...normally heavy breathing means rebuild time...it did on mine anyhow.

Thanks Dan, I have a baileys breather knocking round somewhere ill dig it out. The engine has had a rebuild and i have all the receipts to prove but you never know i suppose.

 

not some thing silly like a nackered cap??

 

Yer rings have gone! Mabey

 

But its just had new rings and pistons, shells etc.........

 

as said above could just need a new cap. thats what i thought was mine untill i found out the rings had gone

 

Yep was the breather blocked solid , cleaned it out with some TFR, water and an air line. Now works a treat . Sending the turbo off monday for a recon
