My fiance's son owns a 2014 F150 with the 5.0L that has 196,000 miles on it that he bought new. He works for the railroad and travels for his job thus the high mileage but most of the mileage is highway miles.
This truck had been totally trouble free until about 190,000 miles when he started getting a slight tapping noise in the engine at certain rpms. He took it to an independent shop and they determined it was the cam phasers. He had Motorcraft cam phasers installed and at the same time had an aftermarket timing chain kit installed. Noise in the engine is now gone and the truck runs fine with no CEL.
So fast forward to last week and about 5,000 miles later, he is out of town for work and his truck starts running like crap and the CEL comes on and it feels like it's missing. He takes it to Autozone and they read the codes. One is a P032 and the other is a P0019. P032 is a cylinder 2 misfire and P0019 has to do with the cam position sensor on bank 2. He only has a couple of days left until he comes home so he keeps driving it.
He comes home and takes it back to the shop who did the repair and they don't know what is wrong. Someone(not the shop) had convinced him that the problem was a bad fuel injector on cylinder 2 so he had the shop install a new injector.
Of coarse that doesn't fix anything so he replaces the plugs which are the original ones and of coarse that doesn't fix the misfire. They also moved the coil pack around and the misfire is still in cylinder 2.
He has me put the truck on my scanner and it still shows the two codes I mentioned before but now had a P0018 code which had to do with the other cam position sensor on the same bank. Truck is idling very rough and you can tell it's misfiring. I tell him it's possible he has a compression problem in cylinder 2 since they have done and replaced pretty much everything for that cylinder. He makes an appointment at the local Ford dealer and they look at it and tell him he needs a new engine to the tune of about $9,600 and that he has low compression in four cylinders. He brought the truck home and said he is not spending the money to replace the engine. He had to go back out on the road for work so nothing has been done to the truck to verify if the compression is in fact bad. He took a different vehicle so his truck is just sitting.
So I have a few questions. If the dealer's diagnosis is correct, what could have caused this compression issue on what is supposedly a pretty durable engine. The entire time he has owned it, he has changed the oil using the OLM which usually tells him to change between 9-10 K miles. He always uses Motorcraft 5W-20. 98% of the miles on the truck has been long distance highway miles. Do you think that the long oil changes with the 5W20 oil could be the cause?
Could the cam position sensor issue have caused some type of damage to the engine resulting in low compression?
Could driving it with the misfire have caused the low compression in such a short time? Only cylinder 2 shows a misfire on the scanner. He didn't tell me if the dealer had told him what cylinders had the supposedly low compression.
What could be the cause of the P0018 & P0019 codes? Something in the original repair that went bad?
Thanks.
