Nav Posted March 26, 2012 Share Posted March 26, 2012 Hi guys,I have a few questions regarding an engine rebuild;When rebuilding an engine, say if the block was re-bored, do you re-bore the block to the next size up from the original size? Is that dimension set or do you bore it to the next size pistons available? If the engine was not re-bored but just honed can I use the original pistons with a new set of rings or do I have to change the pistons as well?When rebuilding an engine, does the values and springs need to be replaced or the old ones still useable? Do I have to change it if the engine was re-bored?And is there a list of standard things that needs changing when building an engine; i.e. bearings, gaskets etc.And one last question, is it better to get a decent second hand used gearbox or build the one already have to use with the new engine. (Mine is crunching in almost all gears; first gear is a pain sometimes to get into, have to yank it into gear. Second, Third and fourth crunches when going to gear. Fifth seems ok and reverse again not that smooth. Even when in gear the gear stick moves around like its in neutral, soo much play )If anyone can shed some light into these questions it will most appreciated. 1"£££$££"!!
