Have a 2010 Toyota 7fdu60 bought it brand new has only 1375 hours
on it. When changing oil on this machine the oil dip stick must be pulled to let air out of block when adding the oil this was done the first 3 oil changes but not the forth, after changing oil it was hard to start but started ever sense then its a little more noisy I delt with it but just a few weeks ago it started going though a lot of fuel and smoking so I had Toyota come and look at it they said it was injectors so $2503.00 dollars later it was a bit better but yesterday it started smoking worse then ever and running rough after it warms up its stops smoking and runs fine. I'm at my wits end any help would be appreciated thanks chris
