Those miles I put on it where all highway hauling ass miles. It did not smoke but it ran hot on my sister one day and the next day it would not crank. Im thinking a lot of moister in the engine or something related, anyway ,I really want to do a performance build up...I am really interested in getting at least 200hp from my zetec. I would love to get the aftermarket intake manifold seen on this site and chrome rings along with a good port and polish with some aftermarket cams and a header...but thats it. I know i will need new bearings rod bolts etc. I still havent got any ideas on where to get those lifters and if the part on fordparts online is for an entire set or not?
