I kno I've brought this up b4 but the fix I was told didn't work. I check my fluids in the truck every month and every time I pull the engin oil dipstick it has a little oil right on the very tip or has none at all. She does blow a little blew smoke wen idoling but wen I step on the gas there is still some blue but mostly black. She does have a small leak wher the motor meets the Tranny but its not big enough to justify the loss of that much oil. What can I do to fix it. Refilling the oil every month is starting to get expencive.

 

i had the same problem but mine was the turbo. it went bad and i got another one. but you might wanna check the oil return from ur turbo to ur intake that seal on mine split and was misting oil.

 

CDR valve. Check that too.

 

You still have plenty of power? This is one of things that could get difficult. It is always something simple when the truck still runs. If you think about your truck and where the oil is you have a few places to look. This might have to be looked at by a specialist. The places to look into is; cylinder compression, is it good? High Pressure oil System, is there a possible leak it could be internal. Your burning oil so it is time to realy look into it. It might be that a piston ring has gone bad. any place that the oil circulates need to be looked into or tested.

 

my truck isnt turbo, ive already soaked the cdr valve in gas and cleaned it up nice lke a month ago,the truck has plenty of power.

 

Aw Crap I did it again you have an idi! No hpop! Sorry. you still have plenty of power, cool. Well geeze? Must be a seal in the heads?

 

well, with the rear leak, i am gona say rear main seal, witha mix of shot valve guides and worn rings.

 

yea but wouldnt worn rings cause a loss of horse power. not to make my truck sound bad *** or anything but with the 39 inch tires with stock 4:10 gears itll pull my 7,000lb boat like it wasnt even back there. thats what dosent make sence to me. im thinking mabe even tho i cleaned the cdr valve mabe its jus no good and needs to be replaced. its gota b somthing in not thinking of, i went RPM diesel which is a reputable diesel shop round here and the tech mentioned somthing bout the seals that are on the ip where it bolts to the timing chain gear, he said there is a chance if they are bad then oil could be getting into the pump there and its just injecting it into the engin along with the fuel, does that sound like somthing that could happen or him just blowing smoke up my but so ill pay him to rebuild the pump

 

well, if thats what he said, i would never go there again. first off, no timing chain. all gear driven. there is no oil pressure at the front of the injection pump, so no real way for that to happen.


if u can blow both directions threw the cdr, it is bad.

also from the factory there are NO exhaust valve seals. installing seals on the valves helps alot.

took me from 4 qts between oil changes to just 1 qt.

 

Yep, I had same problem about a year ago. Same questions and I got same answers as you in this post. The only thing that helped was the valve seals. My exhaust umbrella's were hard and cracked. For about $25.00 and a couple hours of work this is the way to go.
