engine missing and white smoke
this is long so bear with me please. I have came to CA from WY in my 97 f250with no issues then the next morning started it and it was missing and smoking brought it to a shop they told me my idm was bad they replaced it then said 4 injectors on pass side was bad I told them 2 of them are new with less then 900 miles on them then they said 3 was bad they replaced them and said cyl 5 had no compression. so I said Id come get it payed 1803 for nothing it was running the same. so I got a used motor and put it in with new turbo fuel pump uvch and glow plugs and relay fired it up lots of white smoke and missing I figured it just needed to run it to get the oil to build up. so I did smoke got less so I took it for a ride when boost hit 17lbs it started blowing white smoke and died. then it would turn over but not start oil pressure was gone. after turning it over for about 15 min it started and oil pressure was back. still missing pulled valve covers and pulled one injector plug off at a time and 5 and 7 are not changing the miss smoke is very light at a idle now but get worse the more fuel you give it. it has got me stumped new cps as well checked wires from injectors to idm all are good. please help we are disabled and stuck at a campground.
