hello to everybody this is my first post in this forum I have been owning my truck for two years and I haven't done nothing major just brakes and tires and regular oil changes and now two weeks ago it started to blowing alot of white smoke and I noticed that the oil pressure gauge stopped working and started leaking motor oil from the exhaust pipe from the catalyst converter to be exact I have no clue what that could be any suggestions will be highly appreciat

 

That sounds like a blown turbo seal, don't run it until you get it fixed cause more likely than not there isn't any oil pressure

 

I really have no clue where I can buy this Turbo I live in Fresno CA or if I can fix this my self ?

 

It can be fixed just depends on how comfortable you are with your mechanical abilities. It involves taking the turbo off, pulling it all apart to replace the seals. I'm sure you can find the seals at the dealership.
