engine rebuilding to spec

[BlitZ]

Hi all,


I am wondering if most rebuilders (workshops) torque all engine internals to spec in a rebuild or do they just guesstimate...... cause i cant imagine them find a spec sheet for each rebuild...

and with an engine rebuild..........
what component is the most likily cause of some of the badly built engines out there.. (no power- drinking oil?)
(eg. honing, seal installment, torque (screwing seals) etc)


thanks in advance,
noobie dan
