2007 Expedition - Need new engine???
We ordered the car and had it built specifically for us at the end of 2006. Have babied the car the entire time (full synthetic every 3000 miles) and no major wear and tear besides the normal trip or 2 over the years to Florida. Car started running rough last weekend, took it to the shop and I was told I needed a new engine - $8k!!!!! This is my family mechanic that has fixed all of my cars and is trustworthy. 140K miles. Anybody else find this odd that an engine won't last more than 8 years????
Thanks.
Mark

Funny you should post this today. We also have a 2007 Expedition EL Limited. 110,000 miles. On Sunday, it just would not accelerate. Took it to the local Ford dealership. They got the following codes from one side of the motor. P0012,P0016, P0300, P0302, P0303, P0304, P0316. They told us the car jumped time with possible catastrophic damage and would recommend a new motor! We're having it towed to a family's garage that has a lot of Ford knowledge. We have to get a second opinion. I'm curious which codes came up with your 07 Expedition and is it a defect in this motor in particular?

New Motor 07 Expedition
We towed our expedition to a family's shop who is very knowledgeable. He said by the time they take the whole motor apart, we'd be in it for several thousands of dollars and won't be sure they address everything that may have been damaged. So it looks like we're getting a Jasper motor installed. $6000.00. 3 year 100,000 mile warranty. I still can't believe a 07 motor with 100,000 miles would be shot.

Make sure it is not a variable cam timing solenoid. There is 1 in each rocker cover for each bank. When they go bad, it will jump, backfire, misfire, etc. we had one go bad on the wife's 08 Expedition. Reman engine with 30k. Had dealer replace for roughly $300.

Reply/Question
Do you mean we should make sure the Jasper motor we are going to buy to replace original motor may need this replacement? Or do you think that's what may have caused the original motor to jump time? Thanks

Did they tell you why exactly you need a new engine? Sometimes, (as dave91gt said) can be caused by a malfunctioning VCT solenoid valve, or possible sludge or debris buildup on the solenoid screens.
I'm assuming they put an oil pressure gauge on it, since oil pressure is the more common causes of rough idle and random p03XX codes for misfires.
Oil pressure should be 25 PSI at hot idle. Below that: the cam phaser will not set back to idle postion. Diagnosing what the cause of the low oil pressure is can be a pain. It can be anything from crankshaft thrust bearing wear, causing excessive crank walk, sludged oil sump (rare), or other debris like pieces of timing chain guides blocking the sump screen, worn camshaft journals bleeding oil pressure when hot, blown timing chain tensioner seals. In other more rare cases it can be caused by the oil pump too.
The fun part is finding why the oil pressure is low, if that is the case with yours. Because there is so many places that oil pressure is known for leaking down in the engines. Time consuming to find and high labor charges because of tearing the engine apart trying to find the culprit. They just recommend a long block most of the time.
