My 2016 F150 5.0 is making a valve knock at slow acceleration on low RPMs, and then it goes away. Fast acceleration doesn't make any knocking or noise. Also, at idle, it has the typical piston slack. These issues don't always duplicate. Do you believe replacing the solenoids will fix it? PS: No fail codes found.
Yes valve covers need to come off. Don't think there is a shortcut around that much. The valvecover bolts them selves are available, so you can get replacement if you can get the bolt out
I could have removed the heater hoses, then I would have added coolant cost, and more labor to bleed the coolant, as well as risking breaking a quick connector at the firewall. Generally techs like to work around stuff if possible instead of removing everything. Time = Money
If the seal for the solenoid is leaking can it be replaced from the top? Or does the cover have to come out. Also what was the symptom that prompted the solenoid replacement?
@@Patman03sprcrw my truck has random stumbles and rough idle intermittently, sometimes it will die but no check engine light. I’m tempted to replace vct solenoids
Interesting... I don't think it's worth wasting coolant and all that mess, and a potential leak down the road. But if you're due for a coolant flush, you could do two birds with one stone 👍
I would remove them. They're up high so I doubt you would lose much coolant. I would gladly undo two hose clamps and replace a bit of coolant to have one less thing to fight with.
I just got a quote from my Local ford dealer of $5000 to do this. $2200 in parts and $2300 in labor, plus some other bogus charges and tax. My truck is running like total crap now. Is this all there is to it? I can buy Fords parts for about $200 and do it in about a half day myself ????
They might have quoted the camshaft actuators too for that kind of price, you're almost in reman engine territory at 5k lol And yes this job is that easy if this is all you need to do.
@@Patman03sprcrw ...so, my truck has 126k miles on it. I have always used full synthetic oil in it and always replaced it at 5K miles. I really find it hard to believe that the chain and tensioner etc is worn out. I am just gonna replace the VCT's and hope for the best. What do you think?
@@Patman03sprcrw was on occasional stumble or misfire, and or stall while idling. Now rough running, some loss of power at takeoff, bucking when you are at cruise speed down the road, still will stall when stopped occasionally.
