I just bought an 05 Bentley GT late last year. This is the first time owning a GT and I previously had a 17 Bentayga W12. Recently my GT car has been vibrating when idling. A few missfire codes appeared, I replaced all the spark plugs and ignition coils and replaced the injectors and fuel pump. That phenomenon has improved significantly, but I really want to fix the vacuum leak without removing the engine from the chassis. I have reviewed some ways to bypass the air pipe above, but I know that the air pipe on the 05 GT car also extends down to the rear gearbox. Someone with experience please help me. I am in Vietnam. Thank you

My VIN SCBCR63W85C028546

 

Hello @gab ,
Welcome to 6speedonline !

As to the vacuum leaks over the top of the transmission, there is no way to repair them without dropping the engine transmission package, an 05 is an engine out job.
