Motor Oil Eating

[podirtfarmer]

Well the truck runs great but now all of a sudden it is guzzling oil 5qts in less than 200 miles smokes out the exhaust has a odd smell nothing in the coolant. Ran great on a run to Iowa and back 2500 miles used 2-quarts and that was towing a 5th wheel back running at 70. no leaks under truck truck has 230000 miles Would it be better to just pull it and replace with lower milage motor or see what is wrong with this one.Any ideas would be great. Thanks

im assuming theres no oil in your turbo? no excess oil? if its not the turbo its your rings...ouch.

Could be an injector O ring.

If it happened out of nowhere its probably the oil seal on the exhaust side of the turbo. If your rings were bad enough to use 5 quarts in 200 miles you'd know it. The truck would run like crap and probably would start really hard. Start by pulling your intake hose and see if the trubo has any shaft play, up and down, side to side, and in and out.

Well no play in the turbo it did star hard this morning like the batterys were low then fired up and now it is smoking all the time when it is running idling or reving not a real blue smoke but smoke odd smell not coolant smell Also the vent out of the valve cover into the intake has a lot of preassure it seems to me and if i cover it it builds up more pressure Did my engine die . Any one have a motor for sale.

Well checked everything some of the injectors are shot. Now do I sink all the money to replace these or I just had a option open up I found a 2001 with 55000 miles on it the owner had a accident and the truck is totaled he will sell me the engine and trans for about the same $$ as the injectors would cost to do. I think she going to get a heart transplant.

Well the other engine fell through the guy who had it sold the computer and it has not run in over a year. I aasked him if how long he would cover it if it did not run I would have got a tail light warranty thats tough when you spend tht much money. So now i am looking for Injectors I would like to get some thing with some more power I also tow a 30ft toyhauler any direction on this would be great thanks

[jethro]

i would just get stage one sticks new oring and new cups as they may also be bad. is there oil in the fuel filter? or any black stuff in it

[podirtfarmer]

The fuel in the bowl is dark in color and has a more slippery feel to it.

That is the diagnostic test for injector o-rings. When the lower injector o-ring goes bad, oil from the HPOP rail gets forced into the fuel rail, and backs up into the filter assembly. Change out your o-rings and you'll be running as good or better than you were before. I wouldn't even waste money on new injectors because the diagnosis of a bad injector was probably because that cylinder was burning more oil than fuel.
