jordan10125 Lucky u didn't spend $1000 in accidents I replaced spark plugs coils and injectors...turns it it was this a $5 dollar repair part from Napa 😭 but seems to run smooth now than ever coils and injectors were 15 years old stock was good to replace them anyway spark plugs were 5 years old this was on a 2001 Ford Expedition 5.4L Triton

👏🏻 great work. Yeah always love a quick and cheap fix!! So glad this video is still helping people. Cheers

@@ScouserTech Yes, the gift that keeps giving.

RJ can’t say this enough, thank you! So happy to see this video is helping others many years after. Cheers !

Christopher Luke Glad I could help

Scouser Tech mister, i have a 99 mustang & makes the same noise & when i turn off the car it makes a pressurized air release sound, could it be the pcv valve?

Awful response time, I know but were you able to find out if same issue?

So glad this is still helping out. Truck sounds so much better when the noise goes away huh?

God yes!

Mine doesn’t rattle until I take it out while running then when I install while still running it keeps rattling. When I turn off truck it stops rattling after I restart it won’t rattle, is this normal?

So glad this helped. I remember we had thought it was a pulley but love when they are quick and cheap fixes

No codes on my end. Just the loud noise each time truck was started and ran

Anthony E I know my 01 5.4 liter is making this same sound and I never paid no mind to it but the other day check engine light came on and now she's throwing a couple codes. Bank one to lean and bank two to lean. Messing around with stuff ended up pulling the valve after reading that the pcv valve or hose could be plugged and be a problem I put my thumb on the pcv valve and got string suction but notice when I put it back the humming noise started again so for the small fee of 5 bucks for a new one I replaced it even if it's not my problem cheap replacement that can lengthen the life of your engine. And back to you question assuming you've fixed it since 11 months ago my cylinder two started misfiring one random day wasn't sure what the problem was but got the code read and hoped to god it was just a plug and sure enough I pulled the plug out of the cylinder and it was disgusting. I don't mess with the plugs in my 01 expy because I hate the thought of over tightening and stripping these stupid aluminum threads and popping a plug out while on the road but I replace them as they go. I know it's not smart but it does the trick and gets me rolling again.

Sorry just seeing this. The ticking can happen with higher mileage cars. Did you change out your plugs and coil packs since?

Sorry for late reply But I only encountered noise. Came on sudden and then once fixed never returned

You ever find the problem?

Your welcome

Did ever figure it out?

Thanks Norberto. Glad it is still helping out

Robert Armstrong yeah when it initially came up I was like uh oh power steering or a belt but once under the hood I was able to track it down 😉

Was a quick flip but I agree. Western NY winters make keeping it clean very hard

+Scouser Tech i know the feeling i live in canada it sucks but once summer comes its always clean

Yes the previous owner had all sorts hooked up to it. Was changed shortly after video was made with brand new battery.

Thomas ohman These trucks to not have variable valve timing meaning they do not have cam phasers. This is a 2V engine and not the newer and now discontinued 3V engine
