Ok

Let me start with.. This is a 2000 ranger 4x4 4.0L OHV.

I just recently purchased the long block from ATK. all sensors replaced. new oil pump.. Took my time with the install.

Last night.. I fired it up for the first time.. right off the bat one of the lifters is tapping :( ..

I just getting some thoughts on this and what if anything I can do.

I have contact ATK about it. Their technician said to go ahead and drive it 600 miles and see if it shuts up. Which I don't mind doing.

Whats your thoughts and would any thing added help.. if it is just stuck or air trapped..

Thanks.

 

It takes time for the oil to get into the lifters. Did you install the lifters, or was it them?
Because if they weren't soaked in oil. they'll tick
If they weren't installed and primed correctly, they'll tick until oil reaches it.

 

They were preinstalled from ATK.. So I don't know if they soaked them.. heh.. but they do a hot run on the motor.. So I would think they would soak them. Guess it may just take some time.. Ahh hate hearing a ticking noise on a new motor.. :(

 

I would say next time you start it up. let it idle for a good 10 minutes before driving. the oil might not have reached them yet.
My Grand National has a lifter tick for the first 10 minutes when it gets fired up because somebody (my old man) didn't prime his side right.
They fill up with oil and stop after a bit.

 

you sure its not an exhaust leak? they can sound very similar if its the manifold at the head leaking

 

pretty sure it's not the exhaust.. Brand new gaskets / new studs . Using a stethoscope it sounds more centered then outside. I did run it for about 20 minutes on the first startup.. Thinking it would shutup as well. Never did.. I will change the oil out and drive it and see if it shuts up...

 

What oil did you use ?

What oil is recommended by ATK ?

 

I used 10w-30 .. ATK recommended what ford says..

 

Think it would be better to use 5w-30? never used it before. but wonder if the thinner oil will help the issue

 

I thought Ford recommended 5-20W.
My ’88 2.9 and my ’93, 5.0 both called for 5-20 and my latest 03 Ranger 3.0calls for 5-20.

I had a garage do an oil chg and the tappets were singing when I went in to pick it up and the shop owner said they were that way when it came in , NOT !

When asked he said he used 10-30 and when I asked him to chg it to 5-20 he did without any argument.

The tappets quieted down shortly there after, so now that is all I use, although now I use 5-20 Mobile 1.


Does your Ford Manual call for 10-30 weight oil ?

 

Not much difference with 5w30 and 10w30 just the cold weight.

The oil spec is on the rad support for the engine, ford went to 5w20 to increase mileage.

My question is did you put a crappy fram filter on it?

 

Motorcraft oil and Motorcraft filter and drive it. Did you put the heads on? or were they on?

 

But 5-20 is, it made all the difference in the world.

 

Heads were already on from ATK. Which with this motor, you have to pull the heads to replace the lifters.. :( Although, I did use a fram filter. The tick started from the first startup. Currently the motor only has about 20 miles on it. Still ticking.

 

Put a FL-1A filter on it and drive it.
