I have benefitted immensely from your advice and I wished I could donate. Ford F-150 is not common in Port Harcourt, Nigeria. My engine has totally failed and there are neither spare parts nor competent mechanic to fix it.I cannot afford a new engine but I want my vehicle on the road again. If it not illegal, please suggest the brands and sizes of 6 cylinder engines of other cars that will be compartible with the brain box /gear box of F-150 that can put my truck back on the road.
