how do i do a blow by test? what does that involve.i had the valves relapped last week before head was fittedi think the head gasket is ok and i used new head bolts.it was smoking before i took it apart but i was convinced by many people that it was the turbo even tho it hardly had any play in the shaft.

as i said before the engine has done 3k miles but the last time it was in a car was 2003,then it got put in my car last year.unless sumat has happened to the rings while in storage?

ive been offered a fiesta turbo efi bottom end with rings gone.so may put new rings in that lump and swap it over.that way it will have the cps hole if i ever want to swap management.
will my clutch bolt strait on to it or are they different sizes?
