just bought a 89 f-250 with a 7.3, not a pretty truck but a steal at $220. so here are the problems: oil leak, bad water pump, and oil cooler leaking. the first 2 are easy fixes, gonna change the gaskets and have the new water pump ready to be installed. my only problem is the leaking oil cooler. its leaking from the front housing. small pinhole leak at first and under inspection it grew from a little poking around. here is my question, can it be welded, the housing metal seems unusually thin. i also found a cooler on ebay but it looks a little different from mine, will it fit? here's the link: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&_trkparms=tab=Watching&viewitem=&item=200183568080&_trksid=p3907.m32 any help would be grately appreciated. thanks again.
