If got a terrible ticking noise coming from the engine and i am determined that its a lifter problem. How much is this gonna cost to fix and how crtical is it that i get it fixed a.s.a.p? Thanks

 

sorry should have specified that it is a 1998 4.0 p38

 

How many miles on the engine?
What oil are you using and how often do you change it?
Are you using premium fuel?

 

Its got 145000 on it and im using 10 30 for oil. She's had nothing but premium gas

 

You need to change oil, 10w-30 is to thin for these engines, especially during the warm weather.
I use and swear by Shell Rotella 15w-40.
Try that and see what happens, worse case you're out the cost of a oil change.

 

Try a good 15w-40 oil like shell rotella, but most likely , if your'e convinced the noise is coming from the valve-train. it's probably a worn rocker arm and/or rocker shaft. I chased a tick for a while before I found a rocker arm that the steel insert for the pushrod had loosened up and made the racket only after the engine had warmed up.

 

I agree, go with a heavier oil, not to fix the tick but because the engine needs it.
As for your tick, go to the D2 section, look at a sticky I posted for valve train noise, read it, then send me your number and lets talk.

 

Thanks guys, i went with the heavier oil but the ticking is still there. Mike im having a hard time finding the section that your talking about?

Thanks again for all the imput
