I had the same tick in my 1999 3.5 L trooper and they it stopped. Then it started to idling like was going to shut off when I started the engine trying to go in reverse or drive I had to hold the gas and brake to keep the vehicle started . Later , I about 4 weeks I replace all the intake manifold gaskets. The parts was not expense the labor was a killer itself.

This is a very good point. The vacuum leak can get quite loud and sound almost like a lifter ticking. The fuel mileage will drop through the floor as well. I went from 10 to 14 mpg after repairing mine.
The intake gaskets on the 3.5 are ridiculous. If you ever get a chance to look at the OEM's you'll know what I mean. Hard Plastic? Yeah, that'll last forever or until it gets brittle. Fel-Pro makes an interesting replacement that should last. It's my only gripe with an otherwise really nice vehicle. Judging from what I saw when I changed mine I can say that everyone will have to do this repair sooner or later.

I own a 2002 Trooper with 102K miles. I've changed my oil every 2500-3K with Synthetic blend oil, and I've still developed a valve lifter ticking on cold starts. Any suggestions on what I can do to fix the issue (additives suggested?) without major engine rebuilding? Thanks for any suggestions.

With my 1996 I switch to synthetic and still had a tick, after a long time I realized that if I put in an extra quart of oil it stopped. So I run it with the oil above the high mark just a little.

This is an update to my original post. I tried using Lucas Oil stabilizer additive with no luck, but I then added a pint of Sea Foam to the oil & the ticking seems to have stopped. Although I don't live in extreme cold conditions, it did stop ticking when starting cold in 15-20 degree temperatures in the morning.

I switched to synthectic oil and the ticking finally quit and the other thing I do is run it a quart high. Since doing those two things the ticking has final stopped. I am going to check into that Sea Foam I have never heard of it.
#16 of 17 Valve Lifter Ticking Fix?
Feb 09, 2011 (8:27 am)
I just bought my son a 96 Trooper 3.2 OHV and changed oil at 110K with 10w-30 and filter. It still ticked. I then changed the oil at 113K with a new filter and this time with 5w-30. I added the Lucas oil stabilizer(half bottle), and it continued ticking. I have built(rebuilt) stock and performance V8 engines in the past, and knowing that several oil additives(like zinc) have been removed from the regular oils, I decided to add a engine break-in oil additive. I put 1/2 bottle(enough to treat 6 quarts of oil) of Redline Engine Break-in Additive(#81403) that I had on the shelf from Summit Racing. Bingo----ticking gone! Now there is just the normal sound of a Japanese V6(I also own a V6 Toyota with timing belts too). There are other engine break-in suppliers(like Lucas, Comp Cams, etc.). The zinc/phosphorus(ZDDP) may be the missing ingrediant for this problem! I recall that synthetics still have the minerals in them(I have read that synthetics have had some success on other post).
I don't normally post to forums, but I do search them for solutions----so I decided to share this. I hope it works for you!

I changed the oil again at 120K with 5w-30(with no additive) about 2 months ago. The ticking returned last week (as original) when I purchased the car. I added 1/2 bottle of Redline to the oil and the ticking stopped immediately. I will be adding the Redline to each regular oil change.....proof is in the pudding!
