Advisable Specifications (Depending on condition) Treat the following items as suspect, and assume they will need replacing - Also weigh up time needed for thorough inspection against the cost of an available replacement
Replace All bearings, valve guides, springs, timing chains etc Some silent chain pitch can be very hard to come by
Crack / Pressure test cylinder head / block (essential on an unknown engine), crankshaft & con rods - Do not assume that, for example: a second hand block is crack free and will hold water just because the person selling it has given it a nice new coat of paint!
