From another forum about changing motors from 4.6 to 5.4: F-150 from 1997 to 2004 Heritage model years.
exhaust: The collectors on the exhaust manifolds are set at different angles and locations. The 4.6 exhaust might not bolt up to 5.4 manifold. You may need to have a muffler shop modify your...
Will a Expedition exhaust from 2001 4.6 fit a Expedition 99 EB 5.4; also would the 2001 o2 sensors work? I have a feeling they won't, although JC whitney shows the same system for both vehicles.
I found a complete system on CL for $100. I'm not sure what shape its in.
Thanks, I had just watched a video on this. I feel better about it now. I wanted to ask here, because I know there is a lot of bad info out there. Dawn it is.
Looking for advise on flushing radiator/engine. I just put new head gaskets on so the oil problem is fixed
Looking for best product to use for oil in water/antifreeze. Should I wait or do it immediately? Even if I need to wait for some reason, I'll drain and put new antifreeze.
I want to do...
Thank you. Moose I was thinking the same thing. It turned pretty easy when I cranked. I also agree with the simple first approach. I Fixed -Low on fuel, crankshaft position sensor was unhooked, and a weak battery. I'm not sure the exact problem but, after I fixed these it started right up. I...
OK I'm thinking, If I had the crank and cam marks in the correct position (crank at 6:00 and cams at about 11:00 and 1:00) then the #1 should be on compression, correct? Then on the exhaust stroke they will not line up. The only time they line up would be on compression stroke. I hope this is...
It was late last night so didn't checked for spark. The fuel rail had pressure. Checking for spark today.
Bedrck, How can I tell if the piston is on the correct stroke. I knew it did in my head , just couldn't get my mind to understand. Ha. 180 out right. I haven't worked on something like...
Ok, i'm pulling my hair out here. After new head gaskets, valve job, my truck won't start.
I lined up all the chain's marks with crank and cams marks. I had #1 TDC. This may be a stupid question, but does it matter if the piston is on intake stroke or exhaust stroke. I feel like I'm missing...
Just replaced rear control arms (upper) both sides were broken; I've read it's weak spot on 99 Expedition.
Also replaced idler arm, both tie rods ends, sway bar stabilizers (bushings were busted out). It was all over the road. When I came home from vacation, I found the truck in this shape. I...
Here's a very good article on 99-02 Ford 5.4l including the stock pi heads, improved cams, steel cranks. http://www.idmsvcs.com/2vmod/archive/babcox/eb40340.html
I'm removing the head. When I remove the windsor cam, is there a certain bolt pattern or pattern removing the journals, or any special advice I should follow.
I can't find any info on the actually removal of the cam. If anyone has a like I would appreciate it.
thanks
Maybe I should start a new thread, but I'll ask here.
timing chain on passenger has slack, any ideas what could cause this. The guide is also broken. The tensioner piston is not out as far as the other side, best I can tell. I thought I should ask before I finish tear down.
Great article. Thank you
(about half way down their the page is the info I pasted below, although I believe I think its talking about 4.6. I'm not sure about the 5.4.)
The PI heads weren’t installed on everything in 1999, and the parts books aren’t clear about exactly where they were used, so...
Thanks for the information.
I'm Confused about my 99 expedition EB 5.4 triton.
From what I understand the exp did not have PI heads (PI=Square ports)
From the pictures I've seen, mine looks like PI. although I may be wrong.
The engine side stamp reads date 8-14-98 Windsor
Stamp also has...
From what I have read Ford had some problems with their head gaskets during these years.
My questions are.
Does anyone know if it was only certain engines that had these problems, and if there a way to tell?
A lot of people had trouble early (under 50,000) Mine blew at 180,000 so I hopping...
2006 expedition, I did a Parasitic Draw Test and found two problems.
Fuse 4 dvd player was pulling .9 amps. The screen looks slightly illuminated. I pressed the power button and the screen went black for a few seconds, and then back on. It looks like a black screen savor. It also ejected the...
Thanks for the links. I'm having a problem with the battery being dead in the AM: It only happens ever few days or so. This morning it was so dead it wouldn't unlock the doors.
Finally got to fuel pressure test. The pressure holds at 15 psi idling, slight increase on rev. Specs are 28-45. With the key in on position not running it pumps up to 8-9 psi; specs 35-45. The spec info is from just answer . com Shawn, Auto Service Technician. I'm assuming it is correct. I'm...
I got a scan tool
ST FTRM1 % 5.4
LT FRRM1 % 25
ST FTRM2 % 3.1
LT FTRM2 % 25
From the reading does it seem that my O2 sensors are bad? Or not enough info?
Rps 749
Maf flow 6.28
I'm working today so still unable to pressure test fuel.
I did check the intake air sensor, and I think it's ok. If...
I was wondering about the hot vs cold bench test. Thats all I'm looking for is a few suggestions, and yours sounds good. I had thought about the vacum lines collapsing but didn't think about the fuel lines. Do you happen to know, If it were a coil pack would it only show bad when hot. I've heard...
Thanks. Maybe I stated the original post incorrect. It should be.
How do I trouble shoot hot start problems. I have checked these.
I have not ruled these out however it does start for a minute. When I smelled gas humm the pump must be working, so what else could this be. I working on it this...
