Then get back to us.. All of us who are mechanics/ owners, know that this is a challenge.. Just keep in touch, and post all of what you did, and what the truck did.. with respect, Jojo Agreed run it for awhile keep checking the oil in the morning and if it increases on the dip stick you’ll likely have your answer then you can start doing the testing! 2 Quote Link to comment Share on other sites More sharing options...
IGV Posted April 22, 2023 Author Share Posted April 22, 2023 Well I think I have fuel dilution unfortunately, I have checked the oil level everyday since I changed the oil I have a picture from day one April 11 through April 18 Quote Link to comment Share on other sites More sharing options...

Joey Mack Posted April 22, 2023 Share Posted April 22, 2023 I will suggest you do the fuel pressure test that I posted earlier. It will take a few hours, but it is better than just doing a re-build, and you really need to know where the leak is!! Otherwise, what ever you put into the engine will be wasted, because the fuel leak is still there.. 1 Quote Link to comment Share on other sites More sharing options...
IGV Posted April 22, 2023 Author Share Posted April 22, 2023 Yeah I will definitely do the test now, because it doesn't look right on the oil level Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted April 22, 2023 Share Posted April 22, 2023 Good... Just keep in touch here as you go, step-by-step.. Have you gotten a Book on the engine so you can see pictures of where the fuel galleries are and the 2 plugs in the front of the engine near the breather. there are 2 at the rear, around the corner from the #6 cylinder. They are in a straight line to the front plugs.. you will notice that the fuel inlet in the block aligns with one gallery, and the return fitting at the block is in line with the other gallery. Fuel surrounds the EUP's between the o-rings. You may have noticed 2 sets of holes in the EUP's when you had them out.. Quote Link to comment Share on other sites More sharing options...
IGV Posted April 22, 2023 Author Share Posted April 22, 2023 No, I don't have a book where I can get one of those books? Quote Link to comment Share on other sites More sharing options...
IGV Posted April 22, 2023 Author Share Posted April 22, 2023 But I just have to put pressure into the front plugs right? Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted April 22, 2023 Share Posted April 22, 2023 Books are cheap and if you Google them they are readily available, even on the other side of the world were I am They dont have everything in the books but they have almost everything you can think of and lots of leads to finding all sorts of issues A very educational thread going on here Paul Quote Link to comment Share on other sites More sharing options...
IGV Posted April 22, 2023 Author Share Posted April 22, 2023 Ok thank you for the information mrsmackpaul I will buy one Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted April 22, 2023 Share Posted April 22, 2023 IGV... mat I suggest you pick one of the rear plugs. It takes a 1/4'' dr. ratchet to remove the plug.. I suggest a breaker bar to loosen it, because it may be tight enough to break the little ratchet. Here is a picture of the E-Tech supplement book.

IGV Posted April 23, 2023 Author Share Posted April 23, 2023 Ok thank you joey mack I will buy one of those books right now, so to check the eups I use the back of the engine plug and to test the lift pump I use the bottom plug near the timing cover or the breather Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted April 23, 2023 Share Posted April 23, 2023 Just use one of the rear plugs. the pressure will travel through the EUP's and fuel lines. Be sure to remove the fuel line that comes from the tanks and goes to the input of the primary filter. Then plug the port in the filter pad. That will keep the air pressure in the engine and not going back to the tank. leave the fuel pump assembled and pull it back out of the block a half inch or so, so you can see if it is dripping with pressure.. I suggest the rear plug because, when you spill fuel at the front plugs, you won't be fooled in to thinking you found the leak.. the rear plugs do not go into the oil..

Joey Mack Posted April 23, 2023 Share Posted April 23, 2023 I forgot to tell you.. make up a fitting with a shut off valve. you will lose some fuel when you install the fitting assembly. so you will need to crack the valve open and pump the fuel primer until fuel comes out of the valve. This ensures that fuel is in the galleries.. then proceed with the rest of the setup.. the port is 1/4'' NPT.. you can screw an air tool nipple into the valve so you can put pressure to it.

Joey Mack Posted April 24, 2023 Share Posted April 24, 2023 Since you have the pump off. Leave the filter on it tight, and put an air tool nipple in the inlet of the pump, and plug the other end, and pressurize the pump with 70psi. And see if it leaks around the shaft seal.. please wear a face shield when doing this.. jojo 1 Quote Link to comment Share on other sites More sharing options...
IGV Posted April 24, 2023 Author Share Posted April 24, 2023 I just did the pressure test on the suply pump and yes is leaking fuel from the shaft 1 1 Quote Link to comment Share on other sites More sharing options...
