hey guys i have a 2002 lb7 and 158,xxx,ive owned the truck since october..as wierd as it sounds its been problem free until i straight piped it and put a intake on it.and then i started noticing a small coolant leak and a quick thick white smoke at start up,so i replaced the injectors.everything went smooth and it didnt smoke or anything until about two days after.so i went to drain the oil out and it was so sludgy all of a sudden it was like yogurt(textured not colored) so i went 50/50 with oil and kero .ran it got it hot and then drained it out and did it once more and the oil and all seemed to drain out fine.but im confused on why all of a sudden theres sludge built up? the second day i purchased the truck i changed the oil and fuel filter.

i noticed the oil psi gauge to be low also.i love the truck to death.it runs awesome i think,i have been topping the anti freeze off every 4-5 days also.but all of a sudden it seems to be letting me down and turning into more of a money pit then anything

any help or input on anything would be greatly appreciated thanks guys

 

sounds like youre getting coolant in your oil. More than likely headgasket problem.

 

but there are no other signs of a said bad headgasket other then coolant leak.hoses dont get hard,coolant doesnt surge out or anything no coolant runing down the back of the motor either?

 

that's signs of bad headgasket letting compression into the cooling system. They can fail several ways. If it was an oil cooler problem you would more than likely have oil in your coolant jug. So its between a leaking injector cup from when you did injectors or a failed headgasket allowing coolant to seep into your oil.

 

okay thanks for the help!
