02 Dmax making oil

time for all new injectors brother, hate to tell ya that, but it has a few injectors with cracked return passages in them and it's puking fuel into the crankcase. i see trucks getting pulled in here all the time with fuel soaked tailgates from the engine filling up with deisel and flooding over. good thing tho is that deisel is a lite oil and ive neverrrrr seen it hurt a dmax to date if you're under the special policy on mileage, they wont cost ya but 100bucks at the local dealership call your local dealer, give em your info and mileage and have them check to see if you still fall under special policy for replacement, bet ya do.

you've gotta pull a vaccum on the return side of the fuel system on the motor, its a straight up pain in the ass to do fuel in the crankcase is a sure sign of cracked injectors tho, so its not a hard fix, jus a expensive 1 if he's out by mileage lol

its jus pulling bunch of shit outta the way bro, if you have any kinda wrench experience, its not that hard to do. worst part of it is all the damn allen bolts, and there's 1 on the driver's side valvecover along that back that's a straight bitch to get at, sometimes i've had to beat back the firewall as much as possible get em, other times i can use a 6mm bit and put a 1/4 wrench on that and get em out, jus depends.
the passenger side is by far the easiest, so start there that way when you get to the bitchhhhh side(drivers) you'll understand how to do it. its easier to have the injector pulling tool also, but ive done it without before too.

my condolences!

And you are right, pax side is probably a couple hour job, with the driver side being the challenge (a 5mm shallow 1/4 dr bit socket made it's way to my toolbox in case I ever had to do these again). What is the injector removal tool? When doing them last time it consisted of channel locks to wiggle em loose and then prying them up.

Unfortunately, a Tech 2 or EFI Live is going to be your best friend here.

Pensicola injectors seem to be hit or miss. Some people have great luck with them.

After an install of injectors that is getting fuel in the oil, 99.9% of the time is caused by few things. Leaking fuel lines, injector cups not seated properly, the copper washer in the bottom is not seal properly, or an o-ring on the injector got cut or damaged while doing the install.

I agree though, that if the valve covers came off, then it could very well be one or more of the high pressure lines not sealing up very well. Those lines were actually designed to compress around the fitting the first time when they are installed in the factory, and if removed, those lines are supposed to be replaced. They were only designed to be tightened one time, but a lot of people still just re-use them. So its kind of luck of the draw if you get them to line up perfectly again or not.
