that front oil drain is ALWAYS a DEAD GIVE AWAY... thats the only thing i look for really when trying to determine if its a 1.5 or 1.6 engine.. the 1.5 always has a small front oil drain..1.5 engines are still great tho, just not in a 1.5 block. if you could find a 1.6 block, and throw the 1.5 assy in it, you would have one tough, rev happy engine..thats probably what im going to install in my dads Tracker, a Turbo 1.5, in a real turbo 12mm block..
ok, well the 1.6 still has the 1.6 style oil drain on the front of the head.. ALWAYS. and its atleast twice the size of the 1.5 drain.. the big lump in the middle of the head, running down to the block...and i was talking about the gaskets ONLY COMING STOCK in 1.5 engines. im sure there have been more 1.5 gaskets put in 1.6 engines then anyone even hears about..
