Doing both heads vs bent vavle
Thanks for the comments on doing both heads. Let's just call the engine tear-down a new hobby and learning experience. Time costs me nothing and I just want the vehicle running with out a miss fire. I can't see investing in both heads and rationale is if I fix...
Update and Help
At this pace I should have the job done by next FEB. Interestingly enough...the auto shop work that cost me $750 to FIX the problem...(rocker arm) didn't even last from the shop to my house (see the picture - rocker arm fell off again). They also tied wire around the spring...
It has 220 KM (125K Miles). The truck is immaculate so worthy of a few dollars but not an additional $3 grand. it's the 5.4 2V
I'm going to continue the battle and get to head of things. Fixing the valve and putting it back together is a $2K increase in resale value should I decide to dump...
Hmm. Growing confused. I'm cheap and only wanted to fix the bent intake valve and hope to get another 25K.
Opinions please. Pull the passenger head on the frame??? or.... if I have to pull the motor I might as well try and source a low mileage used. Yes or know. Is pulling the motor an...
I spent many hours researching this and have found very little. I hope this helps someone as I document this and hope people provide some insight before I get too deep. Here's the story so far
Misfire on 2. Changed COP plugs etc. Took to large Automotive shop they recommended a 800 spark...
Thanks everyone for the info. The fuel inertia in the back seems to be a reset only button with nothing to turn it off or at least I can't find it. Pressing down does nothing. Anyhow, unplugging the cam sensor worked.....it was all for not because I couldn't get the compression tester to...
Thanks for the Response. Not #10 fuse on the 2003. Relay 203 (PCM) #32, 33,34 is the Fuel Pump Relay, PCM and sensors. Relay 303 is Fuel Pump shut off but that relay doesn't exist.
I'll try the crank sensor if I can locate it.
2003 5.4.
So I've had a single cylinder missfire that gets worse as the vehicles warms (#2). A relative compression revealed the cylinder is over 40% off the others. Is there anything electrical that could give a false reading (i.e cylinder not firing) or is this test pretty accurate for...
2003 Expedition Eddie Bauer. I have spent many hours trying to find our how to shut off the fuel pump/disable the fuel as I'm trying to do a compression test on one cylinder. I had a relative compression done and it was greater than 40% on one cylinder. I just want to compare 3 easy access...
