Whenever I start my truck first thing in the morning to go to work or school or whatever when my engine is cold and has been sitting in the garage all night it makes these clicking sounds. It's coming from the engine bay and I don't know what it is. Sometimes it will do it 2 - 3 times. Or 4 or 5 times. I have no idea what it could be. My warranty is up in 800 miles! If it's an easy fix I will do it otherwise I am going to take it to the dealer. Anyone experience this same thing? Or is it just the weather do you think? BTW, it didn't do this last winter, and I parked on the driveway.

 

Valvetrain clicking due to starvation of oil on initial startup. You use a Fram filter, right?

Next oil change, get a Motorcraft filter. It has an ADV (anti-drainback valve) which keeps the oil higher up in the block to prevent this from happening.

Nothing to get too worried about, though.

 

I do not use Fram. I stopped using those around 18,000 miles or so. I've been using Motorcraft and Mobil 1 on and off. You think I should switch to 0W-20 Mobil 1 instead of 5W-30 Mobil 1? I'm due for an oil change here soon. I might get another Mobil 1 filter. Been using Motorcraft on this last couple times.

 

i think i have the same problem sometimes, is yours real fast like a bunch of poping really quick?

 

A/C Compressor?

 

Yeah! That is exactly what it is. It's like a loud bowl of rice crispies in my engine!

And Diabolic, it is not my A/C compressor. I never use it.

 

I agree with John, it sounds as if it is a lifter tick.

 

Good or bad? Or will it hurt anything in the long run?

 

it will hurt stuff in the long run. where you live it would be a good idea to use the 0w20 motor oil, it has a thinner viscocity in cold weather so it pumps a lot faster. you may also, want to consider AMSOIL, its a 100% synthetic oil, unlike mobil 1, so it stays fluid better in cold weather

 

I have given AMSOIL some thought but I don't like the idea of leaving it in my engine for 25,000 miles/1 year or whatever. I'll give the 0W-20 a shot and see how it does.

 

Don't make me sick John (N3ELZ) on ya! :)

 

Does it stop when the motor is warm or maybe u just can't hear it after the motor is warm bcuz your no longer in a semi-closed, quiet area, like the garage when you 1st start the truck? Next time u pull into the garage for the night, listen and see if you hear the sound? You might just be hearing the injectors from the higher idle and quiet garage???? Or could be like the others said, valvetrain. Also when u pull into the garage have someone hold the engine at a bit higher rpm, like it would be when u 1st start the truck.

Just my 2 pennys.

Worth a try b4 you start thinking it to be the valvetrain.

 

AMSOIL will last that long if you change the filter every 12500. i personally am going to change both every 10k just for the hell of it. But even if you consider the cost of AMSOIL is only about $1 more per quart than Mobil 1, and you get the benefits of a FULL Synthetic oil, even if you just go 10k like me, your still saving money and using a better oil

 

It only makes the popping noises when I start it up after sitting all night and only for a second or two. Then it stops every other time I start it up.

Well Mobil 1 is expensive enough for a college student, lol. And I thought Mobil 1 was fully synthetic as well?

 

i use royal purple with moto filter, it does not do it near as much as it used to when i first bought my truck from the previous owner, it usually only does it in the morning when its typically cold out

 

mobil 1 is not 100% synthetic. in fact, my cousin is the president of marketing for Exxon Mobil, he told me they are coming out with an extended drain 7500 mile synthetic oil. when i asked what was different, he told me they added more supersyn. which means, it wasnt 100% before, and it still wont be 100%.
