1000 miles on the new motor and it runs FANTASTIC. Some of my fuel injectors are leaking. When i start the truck up it surges to life and blue smoke comes out the tailpipe. Iím gonna order a whole new set from rockauto. 368.00 before tax. I also need to drop all that transmission fluid.


Ford Factory secondary transmission filter for the 4R70W.

Gonna hook it up coming back from the cooler to protect my Pic-and-Pull transmission. I have zero issues with the transmission right now and i would like to keep that way.

Are you sure it's not your FPR leaking? I think it would be really odd for multiple injectors to all leak at once.

What you are describing could also be the FPR leaking. After you've driven it around for a bit, pull the vacuum hose off the nipple on the FPR and watch to see if fuel leaks. It's pretty common for the diaphragm to become cracked, and they will **** fuel into the vacuum line.... and essentially it floods the truck - causing the blue smoke.

I will check that out thank you. Im fairly confident itís the injectors. It was doing this before the rebuild but only a tiny bit. I had a fee cylinders that were full of carbon I suspected it then itís highly likely it is now. Im just doing all 8 cause Iím always messing with this thing Iíd like to not pop the hood so much. Plus the injectors were out of the car for over 6 months i had to get 2 from the pick and pull.

Rims came from a 2007 f150 i had to get adapters and cut the factory studs. The guy painted them im gonna sand blast them and put enamel on it. Also i want some Ford chrome center caps. I bet I could find some bootleg ones.
Dropped all the transmission fluid out of the truck and I found something disturbing. The transmission filter was free and floating around inside the pan. Good thing i got that secondary filter. I cut the cooler line and mounted.


Iíll keep my eye on it cause hose claps donít do great with transmission fluid.

Next thing is to put that rear axel on and the 2.5Ē springs in the front.

It wouldn't be pulling unfiltered fluid I'd be worried about... a case of the dry heaves is far more damaging. Is it a 4R70W? Make sure the seal off the old filter didn't get stuck up in there.

OK, that's what I figured... they usually stay pretty secure in a 4R70W.... UNLESS the old gasket/o-ring stayed in there. The E4OD/4R100 though... different story, LOL. Those fall out for no reason, and have caused the aftermarket to make a retainer clip kit for them.

Yesterday i swapped out all my injectors and fuel filter. 3 were cracked and 2 looked really clogged up i bet those were the pick an pull ones. I came out this morning to start it and normally there would be a huge cloud of blue smoke that would produce for the first 10 seconds of running now its just a puff of smoke when it 1st fires up.
So maybe it could be the FPR?
i drove it around and checked it before I ordered the injectors and it was dry. Or maybe my new rings arenít seatings but the last time i seen something like that the engine was really noisy and mine isnít any noisier than the next Over head cam engine.

I believe the coolant leak is connecting from the heater core line coming off the back of the water pump. In the line there is an O-ring this must be the leak. I never replaced that O-ring I wasnít aware that piece even came off cause I tried to take it off on the old block and the pipe sooner failed and got bent up and flattened and it never got loose. Maybe the freeze plugs? I do have one that is weeping very slowly.
