I have a 04 Ram 1500 w/ a 4.7L. Just bought it with 34,000 miles on it. After I changed my oil, @ 36,000 it started to tick like a lifter has collapsed. I used Mobil 1 and K&N oil filter. Should I use some type of oil treatment orgo back to conventional oil. I've heard of the hemi tick but, as you can see, its not a hemi. Any insight or suggestions ? Please help.

 

What octane fuel are you running? I'd start by running a higher grade maybe a simple fix like that. Thats at least the simplest and cheapest place to start...

 

What viscosity oil did you use?

 

I'm running 87 octane gas and used 5w-30 oil

 

How many quarts of oil did you put in? You can try running 89 octance and see if that takes care of it. I know with the hemi's 87 will usually tick without a tuner

 

You say you just bought it, could it be that you might not have noticed it before the oil change? Reason I mention is because the 4.7's are known to crack exhaust manifold studs. The exhaust leak sounds very much like a lifter, but goes away once it warms up, as the manifold expands. Just a thought, I have that problem now.

 

Hanson, I put 7 qts in I think. anyway the level is reading full. I'll try the higher octane gas as well

 

United, It's possible that I didn't notice it but its pretty noticeable now. I have heard about the exhaust problem, but it's not leaking bad enough to see any signs of a leak. As you said, it does get quieter after the engine warms up, but doesn't disapear. Wouldn't a lifter do the same thing untill it finally gets enough oil to "pump it up" some?

 

Alot of the 4.7's will tick on a cold start-up (mine does) but then it goes away after a minute or two. Is this what you are experiencing?

 

Octane shouldn't cause a tick at idle. Try some conventional oil and seeif it quits.
