right, as you know the fiesta rs turbo has a shit oil return to the block, so i had my return put into the sump for better draining, while the sump was off i sent the turbo unit (t2) to carl at g.b turbo solutions who gave it a checkover and freshen up - he is a regular user on here .

started the car up and all is well with no leaks , revved it up and can smell some oil from the exhaust, left it running for 20 mins and again revved it and still a blueish smoke. now the engine reads 170psi all over on a dry compression test, all breathers are brand new and stem seals have been replaced. the motor has done 6 miles in 5 years as its been in the garage! only on 46k as well!

any solutions to whats going on or does it need a hard drive?
