My 92 XJ had lifter tick, but also made a ton of noise (suspension, body creak, blah,blah, and blah) and so I couldn't hear it all the time. I could only hear it at low speed or on start up.

My new 96 XJ is exceptionally quiet and I can hear the lifter tick until it's been running for a few minutes. Is that normal? And will sea foam help that? Just had the oil changed at 135k and went to a semi-synthetic blend. PO used regular oil. I don't notice any lack of power, no hesitation, no smoke and it burns very little oil, so I'm assuming it's not a piston skirt issue.

 

What brand oil filter.

 

Exactly...

Also, I wouldn't use seafoam.

Shine a light into the oil filler hole and assess the sludge. Post the pic here if you want.

 

Valvoline oil filter. Wife says she can still hear the tick after it warms up sometimes. It's hard for me to hear with the wind noise.

 

Don't know the quality of Valvoline filters. Wix is the filter of choice.

If you suspect lifter tick when started cold, do this:

Shut it off. Wait 10 seconds and restart. Noise gone?

 

I use a Napa Gold. My dads LJ sounded like w a train clicking when it was running. Got rid of that fram and now it is quiet as can be

 

Napa gold is wix.

 

I know

 

What'r you getten after Pete? The drain-back valve?

 

Nope. Lets the lifter get oil.

 

I have lifter tick due to a worn cam bearing. No special oil filter can fix it for me...

Pop the valve cover off and look at your lifters. Could be anything from a loose bolt on a rocker arm to apparently your oil filter....

 

How in the world do you get a lifter tick from worn cam bearings?

And you're commenting on oil filters?

Your method to determine this?

You can see lifters with a valve cover off?

Poor advice ^^^^ here.

 

I should have it in my buddies shop this weekend so I can give it a more detailed inspection.

 

After investigation,if it's just a lifter tick try using this.
Worked on my wife's '04 Grand.
